RESUMEN

Zinc oxide nanoparticles have wide range biological, biomedical and environmental applications. However, traditional nanofabrication of ZnONPs uses various toxic chemicals and organic solvents which limit their bio-applications. To overcome this hurdle, Bauhinia variegata derived buds extract was utilized to fabricate ZnONPs. The greenly generated ZnONPs were successfully prepared and extensively characterized using different analytical tools and the average crystalline size was calculated as 25.47 nm. Further, bioengineered ZnONPs were explored for multiple biological activities that revealed excellent therapeutic potentials. The antibacterial potential was determined using different bacterial strains. Pseudomonas aeruginosa (MIC: 137.5 µg/mL) was reported to be the most resistant variant while Bacillus subtilis (MIC: 34.38 µg/mL) was observed to be most susceptible bacterial strain. DPPH radical scavenging potential was measured to determine the antioxidant capacity of ZnONPs and the highest scavenging potential was observed as 82% at highest of 300 µg/mL. The fungicidal effect of green ZnONPs in comparison with Amphotericin B was assessed against five selected pathogenic fungal strains. The results revealed, Fusarium solani (MIC: 46.875 µg/mL) was least resistant and Aspergillus flavus (MIC: 187.5 µg/mL) was most resistant in fungicidal examination. Cytotoxicity potential of B.V@ZnONPs was analyzed against newly hatched nauplii of brine shrimps. The results for greenly produced ZnONPs was recorded as 39.78 µg/mL while 3.006 µg/mL was reported for positive control vincristine sulphate. The results confirmed the category of general cytotoxic for greenly synthesized nano sized B.V@ZnONPs.

RESUMEN

BACKGROUND: Pancreatic adenocarcinoma (PAAD) is a highly aggressive cancer with poor prognosis and limited therapeutic options. Identifying molecular markers and understanding their role in PAAD pathogenesis is crucial for developing targeted therapies. This study integrates bioinformatics and molecular experiments to investigate the diagnostic, prognostic, and therapeutic significance of FGFBP1 in PAAD. METHODS: UALCAN, TNMplot, OncoDB, GEPIA2, HPA, GSCA, KM Plotter, TISIDB, TISCH2, CancerSEA, STRING, DAVID, cell culture, RT-qPCR analysis, western blot analysis, colony formation, cell proliferation, and wound healing assays. RESULTS: Expression analyses revealed a significantly elevated FGFBP1 levels in PAAD tissues compared to normal samples. Promoter methylation analysis indicated lower methylation levels in PAAD, inversely correlated with FGFBP1 expression, suggesting epigenetic regulation. Genetic alteration analysis showed that FGFBP1 is not significantly affected by single nucleotide variants, but copy number variations are present without impacting mRNA expression. Survival analysis using KM plotter demonstrated that high FGFBP1 expression is associated with poor overall and disease-free survival. A Cox regression-based prognostic model confirmed the negative impact of elevated FGFBP1 on patient outcomes. Correlation analysis with immune-related factors indicated that FGFBP1 may contribute to an immunosuppressive tumor microenvironment, affecting immune cell infiltration and function. Single-cell analysis highlighted FGFBP1 expression in malignant, endothelial, and fibroblast cells within the tumor microenvironment. Gene enrichment analysis revealed FGFBP1's involvement in various biological processes and pathways related to cancer progression. Experimental validation using RT-qPCR confirmed high FGFBP1 expression in PAAD cell lines. FGFBP1 knockdown in HEK293T cells significantly reduced cell proliferation, colony formation, and migration. CONCLUSION: These findings suggest that FGFBP1 plays a critical role in PAAD pathogenesis and could serve as a potential therapeutic target for improving patient outcomes.

RESUMEN

BACKGROUND: Oxidative stress mediated by reactive oxygen species (ROS) is a common denominator in arsenic toxicity. Arsenic stress in soil affects the water absorption, decrease stomatal conductance, reduction in osmotic, and leaf water potential, which restrict water uptake and osmotic stress in plants. Arsenic-induced osmotic stress triggers the overproduction of ROS, which causes a number of germination, physiological, biochemical, and antioxidant alterations. Antioxidants with potential to reduce ROS levels ameliorate the arsenic-induced lesions. Plant growth promoting rhizobacteria (PGPR) increase the total soluble sugars and proline, which scavenging OH radicals thereby prevent the oxidative damages cause by ROS. The main objective of this study was to evaluate the potential role of Arsenic resistant PGPR in growth of maize by mitigating arsenic stress. METHODOLOGY: Arsenic tolerant PGPR strain MD3 (Pseudochrobactrum asaccharolyticum) was used to dismiss the 'As' induced oxidative stress in maize grown at concentrations of 50 and 100 mg/kg. Previously isolated arsenic tolerant bacterial strain MD3 "Pseudochrobactrum asaccharolyticum was used for this experiment. Further, growth promoting potential of MD3 was done by germination and physio-biochemical analysis of maize seeds. Experimental units were arranged in Completely Randomized Design (CRD). A total of 6 sets of treatments viz., control, arsenic treated (50 & 100 mg/kg), bacterial inoculated (MD3), and arsenic stress plus bacterial inoculated with three replicates were used for Petri plates and pot experiments. After treating with this MD3 strain, seeds of corn were grown in pots filled with or without 50 mg/kg and 100 mg/kg sodium arsenate. RESULTS: The plants under arsenic stress (100 mg/kg) decreased the osmotic potential (0.8 MPa) as compared to control indicated the osmotic stress, which caused the reduction in growth, physiological parameters, proline accumulation, alteration in antioxidant enzymes (Superoxide dismutase-SOD, catalase-CAT, peroxidase-POD), increased MDA content, and H2O2 in maize plants. As-tolerant Pseudochrobactrum asaccharolyticum improved the plant growth by reducing the oxidation stress and antioxidant enzymes by proline accumulation. PCA analysis revealed that all six treatments scattered differently across the PC1 and PC2, having 85.51% and 9.72% data variance, respectively. This indicating the efficiency of As-tolerant strains. The heatmap supported the As-tolerant strains were positively correlated with growth parameters and physiological activities of the maize plants. CONCLUSION: This study concluded that Pseudochrobactrum asaccharolyticum reduced the 'As' toxicity in maize plant through the augmentation of the antioxidant defense system. Thus, MD3 (Pseudochrobactrum asaccharolyticum) strain can be considered as bio-fertilizer.

RESUMEN

New 2-thioxopyrimidinone derivatives (A1-A10) were synthesized in 87-96% yields via a simple three-component condensation reaction. These compounds were screened extensively through in vitro assays for antioxidant and antibacterial investigations. The DPPH assays resulted in the excellent potency of A6-A10 as antioxidants with IC50 values of 0.83 ± 0.125, 0.90 ± 0.77, 0.36 ± 0.063, 1.4 ± 0.07, and 1.18 ± 0.06 mg/mL, which were much better than 1.79 ± 0.045 mg/mL for the reference ascorbic acid. These compounds exhibited better antibacterial potency against Klebsiella with IC50 values of 2 ± 7, 1.32 ± 8.9, 1.19 ± 11, 1.1 ± 12, and 1.16 ± 11 mg/mL for A6-A10. High-throughput screenings (HTS) of these motifs were carried out including investigation of drug-like behaviors, physiochemical property evaluation, and structure-related studies involving DFT and metabolic transformation trends. The radical scavenging ability of the synthesized motifs was validated through molecular docking studies through ligand-protein binding against human inducible nitric oxide synthase (HINOS) PDB ID: 4NOS, and the results were promising. Furthermore, the antiviral capability of the compounds was examined by in silico studies using two viral proteins PDB ID: 6Y84 and PDB ID: 6LU7. Binding poses of ligands were discussed, and amino acids in the protein binding pockets were investigated, where the tested compounds showed much better binding affinities than the standard inhibitors, proving to be suitable leads for antiviral drug discovery. The stabilities of the molecular docked complexes in real systems were validated by molecular dynamics simulations.

RESUMEN

BACKGROUND: Several WRKY transcription factors (TFs), including CaWRKY6, CaWRKY22, CaWRKY27, and CaWRKY40 are known to govern the resistance of pepper (Capsicum annuum L.) plants to Ralstonia solanacearum infestation (RSI) and other abiotic stresses. However, the molecular mechanisms underlying these processes remain elusive. METHODS: This study functionally described CaWRKY3 for its role in pepper immunity against RSI. The roles of phytohormones in mediating the expression levels of CaWRKY3 were investigated by subjecting pepper plants to 1 mM salicylic acid (SA), 100 µM methyl jasmonate (MeJA), and 100 µM ethylene (ETH) at 4-leaf stage. A virus-induced gene silencing (VIGS) approach based on the Tobacco Rattle Virus (TRV) was used to silence CaWRKY3 in pepper, and transiently over-expressed to infer its role against RSI. RESULTS: Phytohormones and RSI increased CaWRKY3 transcription. The transcriptions of defense-associated marker genes, including CaNPR1, CaPR1, CaDEF1, and CaHIR1 were decreased in VIGS experiment, which made pepper less resistant to RSI. Significant hypersensitive (HR)-like cell death, H2O2 buildup, and transcriptional up-regulation of immunological marker genes were noticed in pepper when CaWRKY3 was transiently overexpressed. Transcriptional activity of CaWRKY3 was increased with overexpression of CaWRKY6, CaWRKY22, CaWRKY27, and CaWRKY40, and vice versa. In contrast, Pseudomonas syringae pv tomato DC3000 (Pst DC3000) was easily repelled by the innate immune system of transgenic Arabidopsis thaliana that overexpressed CaWRKY3. The transcriptions of defense-related marker genes like AtPR1, AtPR2, and AtNPR1 were increased in CaWRKY3-overexpressing transgenic A. thaliana plants. CONCLUSION: It is concluded that CaWRKY3 favorably regulates phytohormone-mediated synergistic signaling, which controls cell death in plant and immunity of pepper plant against bacterial infections.

RESUMEN

This study focused on developing novel pyridine-3-carboxamide analogs to treat bacterial wilt in tomatoes caused by Ralstonia solanacearum. The analogs were synthesized through a multistep process and their structures confirmed using spectroscopy. Molecular docking studies identified the most potent analog from the series. A specific analog, compound 4a, was found to significantly enhance disease resistance in tomato plants infected with R. solanacearum. The structure-activity relationship analysis showed the positions and types of substituents on the aromatic rings of compounds 4a-i strongly influenced their biological activity. Compound 4a, with a chloro group at the para position on ring C and hydroxyl group at the ortho position on ring A, was exceptionally effective against R. solanacearum. When used to treat seeds, the analogs displayed remarkable efficacy, especially compound 4a which had specific activity against bacterial wilt pathogens. Compound 4a also promoted vegetative and reproductive growth of tomato plants, increasing seed germination and seedling vigor. In plants mechanically infected with bacteria, compound 4a substantially reduced the percentage of infection, pathogen quantity in young tissue, and disease progression. The analogs were highly potent due to their amide linkage. Molecular docking identified the best compounds with strong binding affinities. Overall, the strategic design and synthesis of these pyridine-3-carboxamide analogs offers an effective approach to targeting and controlling R. solanacearum and bacterial wilt in tomatoes.

RESUMEN

BACKGROUND: Oncogenic processes in cancer are often characterized by dysregulation of critical genes. Our study focused on the minichromosome maintenance 10 replication initiation factor (MCM10) gene's expression and its potential diagnostic and prognostic implications in pan-cancer. METHOD: Leveraging large-scale genomic datasets, and experimental validation we embarked on a comprehensive analysis to shed light on the diagnostic and prognostic role of MCM10. RESULTS: Our findings underscore the wide-ranging up-regulation of MCM10 across 24 major cancer types, positioning it as a ubiquitous player in tumorigenesis. Significantly, MCM10 up-regulation was strongly associated with poorer overall survival in Kidney Renal Papillary Cell Carcinoma (KIRP), Liver Hepatocellular Carcinoma (LIHC), and Lung Adenocarcinoma (LUAD), emphasizing its potential as a valuable prognostic marker in these cancers. While genetic mutations often drive oncogenic processes, our mutational analysis revealed the relative stability of MCM10 in KIRP, LIHC, and LUAD. This suggests that epigenetic (hypomethylation) and non-mutational regulatory mechanisms predominantly govern MCM10 expression in these cancer types. Further analyses demonstrated positive correlations between MCM10 expression and immune cell infiltration, particularly CD8+ T cells and CD4+ T cells, offering insights into the gene's influence on the tumor immune microenvironment. Additionally, pathway enrichment analysis highlighted MCM10-associated genes' involvement in crucial signaling pathways, such as the cell cycle, DNA replication, and repair. Exploring the therapeutic potential, we examined important drugs capable of regulating MCM10 expression, opening doors to personalized treatment strategies. CONCLUSION: Our study elucidates the multifaceted roles of MCM10 in KIRP, LIHC, and LUAD. Its pervasive up-regulation, prognostic significance, epigenetic regulation, and influence on the immune microenvironment provide valuable insights into these cancers. This research contributes to the growing body of evidence surrounding MCM10 and invites further investigation, validation, and potential translational efforts to harness its clinical relevance.

RESUMEN

BACKGROUND: In the case of COVID-19 patients, it has been observed that the immune system of the infected person exhibits an extreme inflammatory response known as cytokine release syndrome (CRS) where the inflammatory cytokines are swiftly produced in quite large amounts in response to infective stimuli. Numerous case studies of COVID-19 patients with severe symptoms have documented the presence of higher plasma concentrations of human interleukin-6 (IL-6), which suggests that IL-6 is a crucial factor in the pathophysiology of the disease. In order to prevent CRS in COVID-19 patients, the drugs that can exhibit binding interactions with IL-6 and block the signaling pathways to decrease the IL-6 activity may be repurposed. METHODS: This research work focused on molecular docking-based screening of the drugs celecoxib (CXB) and dexamethasone (DME) to explore their potential to interact with the binding sites of IL-6 protein and reduce the hyper-activation of IL-6 in the infected personnel. RESULTS: Both of the drugs were observed to bind with the IL-6 (IL-6 receptor alpha chain) and IL-6Rα receptor with the respective affinities of -7.3 kcal/mol and -6.3 kcal/mol, respectively, for CXB and DME. Moreover, various types of binding interactions of the drugs with the target proteins were also observed in the docking studies. The dynamic behaviors of IL-6/IL-6Rα in complex with the drugs were also explored through molecular dynamics simulation analysis. The results indicated significant stabilities of the acquired drug-protein complexes up to 100 ns. CONCLUSION: The findings of this study have suggested the potential of the drugs studied to be utilized as antagonists for countering CRS in COVID-19 ailment. This study presents the studied drugs as promising candidates both for the clinical and pre-clinical treatment of COVID-19.

RESUMEN

One of the most prevalent chronic conditions affecting older men is benign prostatic hyperplasia (BPH), causing severe annoyance and embarrassment to patients. The pathogenesis of BPH has been connected to epithelial proliferation, inflammation, deranged redox balance, and apoptosis. Diacerein (DIA), the anthraquinone derivative, is a non-steroidal anti-inflammatory drug. This study intended to investigate the ameliorative effect of DIA on the prostatic histology in testosterone-induced BPH in rats. BPH was experimentally induced by daily subcutaneous injection of testosterone propionate for four weeks. The treated group received DIA daily for a further two weeks after induction of BPH. Rats' body and prostate weights, serum-free testosterone, dihydrotestosterone, and PSA were evaluated. Prostatic tissue was processed for measuring redox balance and histopathological examination. The BPH group had increased body and prostate weights, serum testosterone, dihydrotestosterone, PSA, and oxidative stress. Histologically, there were marked acinar epithelial and stromal hyperplasia, inflammatory infiltrates, and increased collagen deposition. An immunohistochemical study showed an increase in the inflammatory TNF-α and the proliferative PCNA markers. Treatment with DIA markedly decreased the prostate weight and plasma hormones, improved tissue redox balance, repaired the histological changes, and increased the proapoptotic caspase 3 expression besides the substantial reduction in TNF-α and PCNA expression. In conclusion, our study underscored DIA's potential to alleviate the prostatic hyperplastic and inflammatory changes in BPH through its antioxidant, anti-inflammatory, antiproliferative, and apoptosis-inducing effects, rendering it an effective, innovative treatment for BPH.

RESUMEN

Objective: Estrogen receptor breast cancer (BC) is characterized by the expression of estrogen receptors. It is the most common cancer among women, with an incidence rate of 2.26 million cases worldwide. The aim of this study was to identify differentially expressed genes and isoform switching between estrogen receptor positive and triple negative BC samples. Methods: The data were collected from ArrayExpress, followed by preprocessing and subsequent mapping from HISAT2. Read quantification was performed by StringTie, and then R package ballgown was used to perform differential expression analysis. Functional enrichment analysis was conducted using Enrichr, and then immune genes were shortlisted based on the ScType marker database. Isoform switch analysis was also performed using the IsoformSwitchAnalyzeR package. Results: A total of 9,771 differentially expressed genes were identified, of which 86 were upregulated and 117 were downregulated. Six genes were identified as mainly associated with estrogen receptor positive BC, while a novel set of ten genes were found which have not previously been reported in estrogen receptor positive BC. Furthermore, alternative splicing and subsequent isoform usage in the immune system related genes were determined. Conclusion: This study identified the differential usage of isoforms in the immune system related genes in cancer cells that suggest immunosuppression due to the dysregulation of CXCR chemokine receptor binding, iron ion binding, and cytokine activity.

RESUMEN

BACKGROUND: Although evidence regarding pituitary tumor-transforming 3, pseudogene (PTTG3P) involvement in human cancers has been acquired via human and animal model-based molecular studies, there is a lack of pan-cancer analysis of this gene in human tumors. METHODS: Tumor-causing effects of PTTG3P in 24 human tumors were explored using The Cancer Genome Atlas (TCGA) datasets from different bioinformatics databases and applying in silico tools such as The University of ALabama at Birmingham CANcer (UALCAN), Human Protein Atlas (HPA), Kaplan Meier (KM) plotter, cBioPortal, Search Tool for the Retrieval of Interacting Genes/Proteins (STRING), Cytoscape, Database for Annotation, Visualization, and Integrated Discovery (DAVID), Tumor IMmune Estimation Resource (TIMER), and Comparative Toxicogenomics Database (CTD). Then, via in vitro experiments, including RNA sequencing (RNA-seq) and targeted bisulfite sequencing (bisulfite-seq), expression and promoter methylation levels of PTTG3P were verified in cell lines. RESULTS: The PTTG3P expression was overexpressed across 23 malignancies and its overexpression was further found significantly effecting the overall survival (OS) durations of the esophageal carcinoma (ESCA) and head and neck cancer (HNSC) patients. This important information helps us to understand that PTTG3P plays a significant role in the development and progression of ESCA and HNSC. As for PTTG3P functional mechanisms, this gene along with its other binding partners was significantly concentrated in "Oocyte meiosis", "Cell cycle", "Ubiquitin mediated proteolysis", and "Progesterone-mediated oocyte maturation". Moreover, ESCA and HNSC tissues having the higher expression of PTTG3P were found to have lower promoter methylation levels of PTTG3P and higher CD8+ T immune cells level. Additionally, PTTG3P expression-regulatory drugs were also explored in the current manuscript for designing appropriate treatment strategies for ESCA and HNSC with respect to PTTG3P expression. CONCLUSION: Our pan-cancer based findings provided a comprehensive account of the oncogenic role and utilization of PTTG3P as a novel molecular biomarker of ESCA and HNSC.

RESUMEN

OBJECTIVES: Prominin 2 (PROM2) gene has been reported as a molecular biomarker of human cancers; however, its role is still controversial. This study was therefore arranged to seek the role of PROM2 in different cancers with Bioinformatics and in vitro analyses. METHODS: A combination of bioinformatics and molecular experiments. RESULTS: Through the utilization of Bioinformatics analysis, it was observed that in 19 out of the 24 human cancers studied, there was a significant increase in the expression of PROM2 compared to the respective control samples. Additionally, the overexpression of PROM2 was linked specifically to a decrease in overall survival (OS) among breast cancer (BRCA), lung adenocarcinoma (LUAD), and uterine corpus endometrial carcinoma (UCEC) patients. Furthermore, advanced molecular investigations were conducted, encompassing RNA sequencing (RNA-seq) as well as targeted bisulfite sequencing (bisulfite-seq) assessments of PROM2. These analyses were performed across an array of lung cancer cell lines (A549, ABC-1, EBC-1, and LK-2) and a normal control lung cell line (MRC-9). Results of these analysis revealed overexpression and reduced methylation of PROM2 within lung cancer cell lines, relative to the corresponding control cell line. This suggests that PROM2 assumes a substantial function in the advancement and course of BRCA, LUAD, and UCEC cancers. Subsequent pathway analysis revealed that genes enriched by PROM2 are actively engaged in four pivotal pathways. Additionally, intriguing associations were observed between PROM2 expression, tumor purity, infiltration of CD8+ T immune cells, and genetic modifications. Moreover, we also predicted a few MicroRNAs (miRNAs), transcription factors (TFs), and potential drugs that could help to understand and better manage these cancers via designing appropriate therapies targeting PROM2. CONCLUSION: Via this study, we effectively revealed PROM2 overexpression as a potential diagnostic and prognostic biomarker of survival in BRCA, LUAD, and UCEC.

RESUMEN

N6-methyladenosine methylation (m6A) is a common type of epigenetic alteration that prominently affects the prognosis of tumor patients. However, it is unknown how the m6A regulator affects the tumor microenvironment (TME) cell infiltration in adrenocortical carcinoma (ACC) and how it affects the prognosis of ACC patients yet. The m6A alteration patterns of 112 ACC patients were evaluated, furthermore, the association with immune infiltration cell features was investigated. The unsupervised clustering method was applied to typify the m6A alteration patterns of ACC patients. The principal component analysis (PCA) technique was taken to create the m6A score to assess the alteration pattern in specific malignancies. We found two independent patterns of m6A alteration in ACC patients. The TME cell infiltration features were significantly in accordance with phenotypes of tumor immune-inflamed and immune desert in both patterns. The m6Ascore also served as an independent predictive factor in ACC patients. The somatic copy number variation (CNV) and patients prognosis can be predicted by m6A alteration patterns. Moreover, the ACC patients with high m6A scores had better overall survival (OS) and higher efficiency in immune checkpoint blockade therapy. Our work demonstrated the significance of m6A alteration to the ACC patients immunotherapy. The individual m6A alteration patterns analysis might contribute to ACC patients prognosis prediction and immunotherapy choice.

RESUMEN

Type 2 diabetes mellitus is characterized by hyperglycemia and insulin resistance. It is spreading around the globe like a pandemic. Major factors behind the development of diabetes can be genetics, environmental factors, dietary choices and obesity. Many medicinal plants have anti-diabetic potential. This study has investigated the anti-diabetic effect of curry leaves extract. This study also investigated the chemical characterization of curry leaves. Phytochemicals including saponins, tannins, alkaloids, flavonoids, phenols and glycosides were also investigated. Encapsulated 5mg per kg of the body weight and 10mg per kg of the body weight were given to treatment groups I and II. Random blood sugar, fasting blood sugar and HbA1c of 45 diabetic female adults were measured on the 0-day and 45th days. All results were analyzed using the two-sample t-test in IBM SPSS Statistics 20. Curry leaves contained moisture (24.1±1.78)%, ash (17.82±2.13)%, nitrogen free extract (36.12±3.52)%, crude protein (8.32±0.83)%, crude fiber (6.98±2.31)% and crude fat (6.87±0.21)%. Mineral analysis showed that magnesium and calcium were major minerals present in curry leaves. Curry leaves extract contained saponins 2.71±0.23, flavonoids 7.84±0.42, tannins 0.91±0.09, glycosides 0.17±0.01, phenols 3.89±0.12, alkaloids 2.01±0.87. These phytochemicals were expressed in mg/100 g of the sample. Curry leaf extract showed a significant (p<0.05) reduction in fasting blood sugar, random blood sugar and glycated hemoglobin in both treatment groups.

RESUMEN

Citrus sinensis is an important member of the genus Citrus which contains phenolic compounds and bioflavonoids which have antihyperlipidemic and antiatherogenic effects. It also has the potential to reduce oxidative stress. To investigate the antihyperlipidemic effect of orange peel powder was encapsulated and analyzed in hyperlipidemic patients. Results showed that it contains moisture (12.2%), ash content (7.9%), crude fat (0.78%), crude protein (12.37%) and crude fiber (13.2%). Total phenolic content and total flavonoid content were observed as 163.17 mg and 17.23mg in quercetin equivalent per gram a dry weight basis. Furthermore, the Orange peel powder was given in the form of medicinal capsules to hyperlipidemia male subjects. The experimental groups (G1 and G2) were given orange peel powder in capsules 400mg/d to the G1 group and 800mg/d to the G2 group for the time of 45 days. The serum lipid profile of patients was measured before and after the experimental trial. The result showed that G1 and G2 showed a decrease in plasma lipid parameters and increased high-density lipoprotein content in blood substantially as compared to G0. Thus, it was concluded from the results that orange peel powder depicts a significant impact on treating hyperlipidemia.

RESUMEN

Hyperglycemia is a condition often observed in diabetics, dyslipidemia and obese. It is a major factor behind the development of diabetes and the reasons can be genetics, environmental factors, dietary choices and obesity. Many medicinal plants have anti-diabetic potential. This study investigated the anti-hyperglycemic effect of apple peel extract. This study also investigated the chemical characterization of apple peel. Phytochemicals including total phenolics and flavonoids were determined. Encapsulated 350mg/day was given to treatment groups. Random blood sugar, fasting blood sugar and HbA1c of 45 diabetic female adults was measured on the 0-day and 45th day. Results showed that apple peel contained moisture (14.71±3.57)%, ash (17.82±2.13)%, nitrogen free extract (32.12±3.52)%, crude protein (6.89±0.83)%, crude fiber (19.17±0.21)% and crude fat (9.91±2.31)%. Findings showed that apple peel contains magnesium (6.61±1.088), calcium (8.17±0.32), zinc (14.08±1.21) and potassium (67.21±1.86). These findings were shown in mg in kg. Apple peel extract contained total phenolic content (TPC) of 8.14±1.07 and total phenolic content (TFC) of 4.89±1.81. Apple peel extract showed a significant reduction in all blood parameters of hyperglycemia. All results were significant at p<0.05.

RESUMEN

Hypercholesterolemia is a condition with elevated cholesterol and lipid profile. It is the leading reason behind myocardial infarction and coronary heart disease. It is observed in young people as well due to a sedentary lifestyle. Triphala powder has a hypolipidemic and anti-hypercholesterolemia effect. This study was designed to investigate the effect of triphala powder against hypercholesterolemia. This study also examined Triphala powder's chemical composition. Total phenolic and flavonoid content were examined. Encapsulated 400 mg and 600 mg Triphala powder were given to treatment groups I and II. Lipid profile parameters were measured and compared at 0 weeks and 10th weeks in all groups. All results were analyzed using ANOVA in IBM SPSS Statistics 20. Results of proximate analyses have shown that Okra pod powder contains moisture 12.27%, ash 11.25%, nitrogen-free extract 45.93%, crude protein 13.37%, crude fat 2.95% and crude fiber 14.23%. Mineral analysis showed that iron and manganese are major minerals in triphala powder. Triphala powder showed a significant reduction in lipid profile parameters in hypercholesterolemia. All results are taken significantly at p<0.05.

RESUMEN

Natural killer (NK) cells are predominant innate lymphocytes that initiate the early immune response during infection. NK cells undergo a metabolic switch to fuel augmented proliferation and activation following infection. Tumor necrosis factor-alpha (TNFα) is a well-known inflammatory cytokine that enhances NK cell function; however, the mechanism underlying NK cell proliferation in response to TNFα is not well established. Here, we demonstrated that upon infection/inflammation, NK cells upregulate the expression of TNF receptor 2 (TNFR2), which is associated with increased proliferation, metabolic activity, and effector function. Notably, IL-18 can induce TNFR2 expression in NK cells, augmenting their sensitivity toward TNFα. Mechanistically, TNFα-TNFR2 signaling upregulates the expression of CD25 (IL-2Rα) and nutrient transporters in NK cells, leading to a metabolic switch toward aerobic glycolysis. Transcriptomic analysis revealed significantly reduced expression levels of genes involved in cellular metabolism and proliferation in NK cells from TNFR2 KO mice. Accordingly, our data affirmed that genetic ablation of TNFR2 curtails CD25 upregulation and TNFα-induced glycolysis, leading to impaired NK cell proliferation and antiviral function during MCMV infection in vivo. Collectively, our results delineate the crucial role of the TNFα-TNFR2 axis in NK cell proliferation, glycolysis, and effector function.

RESUMEN

Rising soil salinity is a major concern for agricultural production worldwide, particularly in arid and semi-arid regions. To improve salt tolerance and the productivity of economic crop plants in the face of future climatic changes, plant-based solutions are required to feed the continuously increasing world population. In the present study, we aimed to ascertain the impact of Glutamic-acid-functionalized iron nanoparticles (Glu-FeNPs) on two varieties (NM-92 and AZRI-2006) of mung beans with different concentrations (0, 40 mM, 60 mM, and 80 mM) of osmotic stress. The result of the study showed that vegetative growth parameters such as root and shoot length, fresh and dry biomass, moisture contents, leaf area, and the number of pods per plant were significantly decreased with osmotic stress. Similarly, biochemicals such as protein, chlorophylls, and carotenes contents also significantly declined under induced osmotic stress. The application of Glu-FeNPs significantly (p ≤ 0.05) restored both the vegetative growth parameters and biochemical contents of plants under osmotic stress. The pre-sowing treatment of seeds with Glu-FeNPs significantly ameliorated the tolerance level of Vigna radiata to osmotic stress by optimizing the level of antioxidant enzymes and osmolytes such as superoxide dismutase (SOD), peroxidase (POD), and proline contents. Our finding indicates that Glu-FeNPs significantly restore the growth of plants under osmotic stress via enhancing photosynthetic activity and triggering the antioxidation system of both varieties.

RESUMEN

BACKGROUND: Previously reported breast invasive carcinoma (BRIC) biomarkers have compromised utility because of their heterogeneity-specific behaviors. The goal of this study was to find BRIC biomarkers that could be used in spite of the heterogeneity barrier. METHODS: Previously reported BRIC-linked hub genes were obtained from the literature via a search technique. A protein-protein interaction (PPI) network of the extracted hub genes was constructed, visualized, and analyzed to explore the top six real hub genes. Following this, real hub genes' expression profiling was carried out using various TCGA data sources and RNA sequencing (RNA-seq) of BT 20 and HMEC cell lines to uncover the tumor-driver roles of the real hub genes. RESULTS: In total, 124 BRIC-linked hub genes were collected from the literature via the search technique. From these collected hub genes, a total of 6 genes, including Centrosomal protein of 55 kDa (CEP55), Kinesin Family Member 2C (KIF2C), kinesin family member 20A (KIF20A), Ribonucleotide Reductase Regulatory Subunit M2 (RRM2), Aurora A Kinase (AURKA), and Protein Regulator of cytokinesis 1 (PRC1) were determined to be the real hub genes. Via expression profiling and validation analyses, we documented the overexpression of CEP55, KIF2C, KIF20A, RRM2, AURKA, and PRC1 real hub genes in BRIC patients with different clinical variables. Further correlational analyses showed diverse associations among real hub genes' expression and other important parameters, including promoter methylation status, genetic alteration, overall survival (OS), relapse-free survival (RFS), tumor purity, CD8+ T, CD4+ T immune cell infiltration, and different mutant genes across BRIC samples. Finally, in this work, we investigated several transcription factors (TFS), microRNAs, and therapeutic medicines related to the real hub genes that have great therapeutic potential. CONCLUSION: In conclusion, we discovered six real hub genes, which may be employed as novel potential biomarkers for BRIC patients with different clinical parameters.
