Genetic mutations in NF-?B pathway genes were associated with the protection from hepatitis C virus infection among Chinese Han population.

ABSTRACT: Host genetic polymorphism is one of major unalterable major factors for HCV infection. NF-?B proteins play multiple roles in immune response and involve in HCV infection and progression. This study was conducted to explore the relationship between single nucleotide polymorphisms (SNPs) in NF-?B pathway and the susceptibility as well as resolution of HCV infection. A total of 1642 Chinese subjects were enrolled in the study, including 963 uninfected control cases, 231 cases with spontaneous viral clearance and 448 cases with persistent HCV infection, and four SNPs (Rel rs842647, NF-?B2 rs12769316, RelA rs7101916, RelB rs28372683) were genotyped by TaqMan assay among them. Potentially functional polymorphisms were analyzed using online bioinformatics tools. The logistic analyses results indicated that RelA rs7101916 T allele (PBonferroni?=?0.016) and RelB rs28372683 A allele (PBonferroni?=?4.8e-5) were associated with an decreased risk of the susceptibility to HCV infection among Chinese Han population, which were consistent with the results of cumulative effects and haplotype analysis. The silico analysis of SNPs function suggested that the genetic variation of rs7101916 and rs28372683 could influence gene transcriptional regulation and expression, subsequently affecting NF-?B pathway activation and the susceptibility to HCV infection. This study firstly reported that the carriage of RelA rs7101916 T or RelB rs28372683 A was the potential protective factor against HCV infection among the Chinese population.

Project description:Psoriasis is a chronic inflammatory skin disease related to immune, whose complexity of molecular mechanisms is still not fully clear. RNA sequencing has been widely applied in various fields including biological medicine. According to the bioinformatics analysis of differential genes, biomarkers and drug targets have been discovered for the diagnosis and treatment of diseases. Besides, the pathological mechanisms of disease and functions of gene can be evaluated. In the present study, we report the application of RNA sequencing in skin tissues from psoriatic and healthy persons. By obtaining 2139 differential expressed genes (DEGs), 208 significantly differential GO terms and 44 significantly differential pathways were generated. We found that the functions of DEGs were mainly related to cell cycle, inflammatory, virus, immune response and metabolic process.The major pathways included cytokine-cytokine receptor interaction, Toll-like receptor signaling pathway, chemokine signaling pathway, cell cycle, metabolic pathways, ribosome, peroxisome, steroid biosynthesis and biosynthesis of unsaturated fatty acids. Furthermore, co-expression network was constructed to identify core genes and relations between genes. we considered genes with high values of degree and k-core difference in the co-expression network as core genes, such as IFNG, IL26, TLR3, PRKCQ, TLR4, CD274, CDK1 and IL17A. We chose CD274, an important immune checkpoint, to evaluate its regulatory mechanisms. Candidate genes related to CD274 were evaluated by the co-expression network analysis, and the relations between CD274 and candidate genes were validated in epidermal keratinocytes. Finally, IFNG and CDK1 inhibitor (indirubin) were found increasing the expression levels of CD274. In addition, indirubin was confirmed to attenuate mouse psoriasis-like skin lesion with the mechanisms related to CD274. In conclusion, this study provides us a comprehensive transcriptome analysis method on psoriasis to identify core genes and explore the important regulatory functions of genes.
