017 and P= 0.011, Selleck GSK3235025 respectively) and significantly lower triglycerides level (P=0.023), total cholesterol, HDL-C and LDL-C levels (all Ps<0.001) than 480 controls. In multivariate logistic regression analyses, a low total cholesterol,
a low triglycerides and a high HOMA-IR are independent factors significantly associated with chronic HCV Infection. In the 160 CHC patients [41 patients with high HOMA-IR (>2.5)], a high BMI, triglycerides and HCV RNA level are independent factors significantly associated with high HOMA-IR in multivariate logistic analyses. Chronic HCV infection was associated with metabolic characteristics including IR and lipid profile. IR was also associated with virological characteristics. “
“Cancer/testis (CT) antigens have been considered therapeutic targets
for treating cancers. However, a central question is whether their expression contributes to tumorigenesis or if they are functionally irrelevant by-products derived from the process of cellular transformation. In any case, these CT antigens are essential for cancer cell survival and may serve as potential therapeutic targets. Recently, the cell-based RNA interference (RNAi) screen has proven to be a powerful approach for identifying potential therapeutic targets. In this study we sought to identify new CT antigens as potential therapeutic targets for human hepatocellular carcinoma (HCC), and 179 potential CT genes on the X chromosome were screened through a bioinformatics analysis of gene expression DZNeP datasheet profiles. Then an RNAi screen against these potential CT genes identified nine that were required for sustaining the survival of Focus and PLC/PRF/5 cells. Among the nine genes, the physiologically testis-restricted dual specificity phosphatase 21 (DUSP21) encoding a dual specificity phosphatase was up-regulated in 39 (33%) of 118 human HCC specimens. Ectopic DUSP21 had no obvious impact on proliferation and colony formation in HCC cells. However, DUSP21 silencing significantly suppressed cell proliferation, colony formation, and in vivo tumorigenicity in HCC cells. The administration of adenovirus-mediated RNAi and an atelocollagen/siRNA mixture against
endogenous DUSP21 significantly suppressed xenograft HCC tumors in mice. Further investigations showed that DUSP21 knockdown led 上海皓元 to arrest of the cell cycle in G1 phase, cell senescence, and expression changes of some factors with functions in the cell cycle and/or senescence. Furthermore, the antiproliferative role of DUSP21 knockdown is through activation of p38 mitogen-activated protein kinase in HCC. Conclusion: DUSP21 plays an important role in sustaining HCC cell proliferation and may thus act as a potential therapeutic target in HCC treatment. (Hepatology 2014;59:518–530) “
“Background and Aim: In human blood, two main subsets of antigen-presenting-cells (APCs) have been described: plasmocytoid dendritic cells (pDC) and myeloid dendritic cells (mDC) which are further subdivided in CD11c-mDC and CD16-mDC DC.
