Relationship between circulating irisin levels and overweight/obesity: A meta-analysis.

Background: Currently, the findings about irisin as a novel myokine related to obesity are inconsistent in overweight/obese people. To our knowledge, no systematic analysis has been conducted to evaluate the relationship between irisin levels and overweight/obesity.

Aim: To evaluate the association between circulating irisin levels and overweight/obesity.

Musashi-2 promotes hepatitis Bvirus related hepatocellular carcinoma progression via the Wnt/β-catenin pathway.

Our recent study observed that the expression of Musashi-2 (MSI2), a member of the Musashi family, was up-regulated in hepatitis B virus (HBV) related hepatocellular carcinoma parenchymal cells. Using quantitative PCR, tissue microarray (TMA) and immunohistochemical staining, we evaluated MSI2 mRNA and protein levels in tumor tissues from patients with different stages of hepatocellular carcinoma with paired adjacent noncancerous sample sets. The following techniques were used to further investigate MSI2 function and its potential molecular mechanism: RNAi, wound healing assay, Transwell assay, quantitative PCR and western blot analysis.
