https://www.selleckchem.com/TGF-beta.html MiR-134 has been reported to have a role in the development and progression of various cancers. In this study, we found that miR-134 expression was significantly decreased in chemo-resistant serous epithelial ovarian cancer (EOC) patients. Over-expression of miR-134 enhanced the sensitivity of SKOV3-TR30 cells to paclitaxel, and increased paclitaxel-induced apoptosis. Further, Pak2 was identified as a direct target of miR-134, and Pak2-specific siRNA increased cell inhibition rate and promoted paclitaxal-induced apoptosis. By regulating Pak2 expression, miR-134 could mediate Bad phosphorylation at Ser112 and Ser136, which affected cell survival and apoptosis. In conclusion, our findings indicate that repression of miR-134 and consequent up-regulation of Pak2 might contribute to paclitaxel resistance.Calpain 3 (CAPN3) is a tissue specific calpain, and its mRNA is the most expressed calpain isoform in skeletal muscles. Many mutations and polymorphisms within the human CAPN3 gene have been reported and related to limb-girdle muscular dystrophy. Several reports link CAPN3 polymorphisms and meat quality. An association between three allele variants in exon-10 of ovine CAPN3 and the yield of fat trimmed meat cuts has been reported. This research investigated the biochemical significance of polymorphic variation in CAPN3. CAPN3 mRNA sequences were obtained from muscle samples collected from lambs which were homozygous for each of the three alleles. Four single base substitutions were found besides those in exon-10, but none of them, including the variations within exon-10, caused a change in amino acid sequence. The expression of CAPN3 mRNA and the amounts of CAPN3 protein were also compared among genotypes, and no significant differences were found. These results suggest that the reported association of specific allele variants within CAPN3 exon-10 to phenotype variations were not direct effects of CAPN3 polymorphisms. Interspecie
