RESUMO
Previously, we determined that the CARD11 rs4722404 single nucleotide polymorphism (SNP) increases risk of early-onset psoriasis vulgaris (PsV). Moreover, the CARD14 gene polymorphism c.C2458T (p.Arg820Trp) is associated with clinical features of this disease. CARMA1/CARD11, CARMA2/CARD14, and CARMA3/CARD10 are conserved across many species and constitute a family of proteins, all of the members of which contain various functional domains characteristic of this group. The NF-κB signaling pathway, regulated by the CARMA family of scaffold proteins and its eponymous component, is a crucial mediator in the pathogenesis of psoriasis. However, little is known about the association between CARMA3/CARD10 and PsV. The aim of this study was to evaluate the relationship between the gene encoding this protein and risk of PsV in the southern Han Chinese population. Genomic DNA from 568 individuals of southern Chinese origin, including 355 patients with PsV and 213 control subjects, was analyzed. We selected seven tag SNPs in the CARMA3/CARD10 gene and genotyped them by the SNaPshot assay. Our results identified no significant association between these SNPs and PsV in the Chinese population examined. Future studies should focus on the potential function of the CARMA3/CARD10 gene in the pathogenesis of PsV.

Quantitative real-time polymerase chain reaction (qRT-PCR) is an important technology used to analyze gene-expression levels. Reference genes, which are assumed to be expressed consistently across various developmental stages and in different tissues, were selected for expression level analysis. Using digital gene expression technology, we selected nine reference genes (18S, EF, CYCOL, SAND, GAPDH, ACTIN, BHLH, TIP, and Clathrin) as candidate reference genes for further study. Using three different analysis methods (GeNorm, NormFinder, and BestKeeper), a total of 144 lily (Lilium x formolongi "Raizan 3") samples were analyzed. The samples were collected from four different tissues under various developmental stages. In addition, leaves treated with different plant hormones were collected and analyzed. The data showed that the stability of the nine reference genes differed among samples, but TIP, EF, Clathrin, and BHLH could be identified as the most stable genes overall. In addition, the relative expression level of LfFT in different lily tissues with the competence to flower was also analyzed to verify the selected reference genes. This study constitutes an important source for selecting reference genes when analyzing the expression patterns of flowering time and floral development regulation genes in lily cultivars.
