RESUMEN

Alzheimer's disease (AD) stands as a formidable challenge in modern medicine, characterized by progressive neurodegeneration, cognitive decline, and memory impairment. Despite extensive research, effective therapeutic strategies remain elusive. The antioxidant, anti-inflammatory, and neuroprotective properties of curcumin, found in turmeric, have demonstrated promise. The poor bioavailability and rapid systemic clearance of this drug limit its clinical application. This comprehensive review explores the potential of curcumin-loaded polymeric nanomaterials as an innovative therapeutic avenue for AD. It delves into the preparation and characteristics of diverse polymeric nanomaterial platforms, including liposomes, micelles, dendrimers, and polymeric nanoparticles. Emphasis is placed on how these platforms enhance curcumin's bioavailability and enable targeted delivery to the brain, addressing critical challenges in AD treatment. Mechanistic insights reveal how these nanomaterials modulate key AD pathological processes, including amyloid-beta aggregation, tau phosphorylation, oxidative stress, and neuroinflammation. The review also highlighted the preclinical studies demonstrate reduced amyloid-beta plaques and neuroinflammation, alongside improved cognitive function, while clinical trials show promise in enhancing curcumin's bioavailability and efficacy in AD. Additionally, it addresses the challenges of clinical translation, such as regulatory issues, large-scale production, and long-term stability. By synthesizing recent advancements, this review underscores the potential of curcumin-loaded polymeric nanomaterials to offer a novel and effective therapeutic approach for AD, aiming to guide future research and development in this field.

RESUMEN

Diabetes mellitus (DM) is one of the severe metabolic diseases found in all types of people's lives in lower, middle and high income countries. It is suggested that the prevalence of diabetes is increasing in many countries and most of the cases are type 2 DM, clinical treatments are changing now to manage type 2 DM, however, up-to-date, there is no diagnostic, prognostic, and therapeutic target for type 2 DM. MicroRNAs (miRNAs) is one of a non-protein coding RNAs that have been regulating a wide range cellular processes and induce the development of many diseases. Most of the researchers concluded that miRNAs involvement is an important process in a broad range of signaling pathways such as cell proliferation, stem cell maintenance, migration, apoptosis and gene or protein expressions. Expressed sequence tags (ESTs) are the best source of coding and non-coding sequences for the identification of miRNAs. Although DNA methylation is an important mechanism for miRNAs up-regulation, this has not been highly explored in type 2 DM. The present study is useful to elucidate the molecular mechanism of MiR-1285-5p in type 2 DM and its role in disease progression and we discovered miR-1285 as a novel prognostic, diagnostic and therapeutic target for type 2 DM.

RESUMEN

Stroke is an important neurological disease in which blood flow to the brain is interrupted and it is becoming an increasing non-communicable disease in developing countries. Current treatment options for stroke is modifying lifestyle practice, diabetes treatment, drugs, and other factors management, but yet no cure is available in sight for the disease, despite it requires new insight into the molecular and therapeutic targets. In general, MicroRNAs (miRNAs) are small noncoding RNAs considered as of greater biological importance and controls molecular signaling pathways in diabetic pathogenesis. Among the reported MiRNAs, MIR-21 is considered to be an important MiRNA, which is frequently elevated in many types of types of strokes, suggesting that it plays an important role in cell proliferation, and apoptosis. Until now, there is no research paper that signifying the role of miR-21 in all types of strokes and the number of studies on the different category of strokes is limited, so in this paper, we are highlighting the recent investigations related to the significance of miR-21 in different types of strokes based on the up-to-date reports. It was found that MiR-21 was found to be normally up and down regulated in all types of strokes, however; we summarize the important research findings related to the role of miR-21 in different types of strokes.

RESUMEN

Myeloid leukemia (ML) is heterogeneous cancer classified by abnormal growth of myeloid cells due to genetic aberrations and mutations. It is generally categorized by clonal disorders of hematopoietic stem cells and differentiation. The molecular mechanism behind the myeloid malignancies is not yet known, but recent sequencing analysis reveals all the mutated factors. As we know that there is currently no compromise on therapy for such types of malignancies and at the present painful process like chemotherapy and radiation therapy are not effective for the treatment of ML, so there is an urgent need to develop a non-invasive biomarker for different types of ML. MicroRNAs (MiRNAs) is a small non-coding RNAs that have been involved in a wide range of biological function and it is the main cause of the manifestation of many diseases. Among the reported MiRNAs, MIR-21 is considered to be an important MiRNA, which is frequently elevated in many types of types of cancer, suggesting that it plays an important role in cancer progressions. So far, there is no paper that signifies the role of miR-21 in all types of ML and the number of studies on the different category of ML is sparse. Therefore, the main thrust of this paper is to provide an overview of the current clinical evidence and significance of miR-21 in ML. It was found that MiR-21 was found to be normally upregulated in all types of ML, however, we summarize the important research findings surrounding the role of miR-21 in different types of ML.

RESUMEN

BACKGROUND: MicroRNAs (miRNAs) are small, highly conserved non-coding RNA molecules involved in the RNA silencing and post-transcriptional regulation of gene expression. miRNAs are well conserved in both plants and animals, and are thought to be a vital and evolutionarily ancient component of gene regulation and also act as oncogenes or tumor suppressors. It is known that Express Sequence Tags (EST) are a short sub-sequence of cDNA sequence, which contain information of condition or tissue specific transcripts (coding and non-coding) of an organism. METHODS: In the present study, we have applied the bioinformatics tools to identify miRNA from breast cancer using EST resource. Through bioinformatics approach, the presence of an EST encoding hsa-miR-17- 3p of breast cancer was identified. RESULTS: Further studies reveal that hsa-miR-17 is confirmed in the breast cancer specific EST sequence among the predicted miRNAs secondary structure. Moreover, miR-17-3p could be responsible for a tumor suppression, which plays a major role in human breast cancer. CONCLUSION: Further studies are required to investigate the molecular mechanisms behind miR-17-3p involves in the suppression of breast cancer cells. Interestingly, our target analysis suggesting that all the targets involved in multiple signaling pathways in different cell regulations moreover, we need to have more number of in vitro and in vivo studies that prove miR-17-3p as candidate microRNA for breast cancer cells.

RESUMEN

Irrespective of positive developments of cancer treatment, the mortality due to various cancers remains high and the mechanisms of cancer initiation and the development also remains mysterious. As we know that microRNAs are considered to be a short noncoding RNA molecules consisting of 21-25 nucleotides (nt) in length and they silence their target genes by inhibiting mRNA translation or degrading the mRNA molecules by binding to their 3'-untranslated (UTR) region and play a very important role in cancer biology. Recent evidences indicate that miR-21 is over expressed in cancer stem cells and plays a vital role in cell proliferation, apoptosis, and invasion. Even though an increased expression level of miR-21 has been observed in cancer stem cells, studies related to the role of miR-21 in cancer stem cells are limited. The main aim of this mini review is to explain the potency of miR-21 in various cancer stem cells (CSCs) and as a new target for therapeutic interventions of cancer progression.
