Primary, Yuan et al. performed all experiments making use of HepG2 and Hep3B hepatoma cell lines stably overexpressing chloramphenicol acetyltransferase or HBx, with out parental cell lines as controls. We carried out experiments using parental HepG2, SMMC-7721, BEL-7402, and MHCC97-H hepatoma cells along with the ordinary liver cell line LO2. Second, the expression levels of HBx in HBx stably transfected HepG2 and Hep3B cells utilized by Yuan et al. weren’t proven. While they described that HBx can boost the expression of upregulated gene eleven , we tend not to see considerable adjustments in the URG11 expression in between HepG2 cells, presumably expressing CAT and HBx, according their Inhibitor seven. We detected HBx expression in every single experiment carried out.
Third, we carried out both knockdown and overexpression experiments to determine the biological function of miR-148a, whereas Yuan et al. carried out only knockdown selleckchem experienced experiments with anti¨CmiR-148a. For cell development and migration assays, the knockdown results with anti¨CmiR-148a inside their examine are unknown, resulting from lack within the data. We showed the expression ranges of miR-148a from the cell development and migration experiments. Lastly, we investigated clinical correlation in 43 sufferers with HBV infection with HCC and 9 patients with out HBV infection with HCC. Yuan et al. assessed clinical correlation in 19 sufferers with HBV infection with HCC. A lot more not long ago, miRNA expression profiling research have shown that HBx expression or HBV infection consequence in alterations of expression of a lot of miRNAs, while the perform of those miRNAs stays largely unknown .
We identified miR-148a WP1066 being a downstream target of HBx. Intriguingly, like HBx, HBV surface antigen and HBV core antigen , 2 other HBV-encoded proteins, also inhibited miR-148a expression . HBsAg indicates latest hepatitis B infection and HBcAg is an indicator of energetic viral replication. The truth that HBsAg and HBcAg regulate miR-148a expression suggests that miR-148a might play a role in viral infection. The mechanisms by which HBsAg and HBcAg modulate miR-148a expression stay for being investigated. It will also be interesting to examine if other tumor viruses alter host miR-148a expression. Loss of function in the p53 tumor suppressor protein has been reported to get a causative occasion in the pathogenesis of the large fraction of human cancers .
p53 is regularly mutated in human cancers, which include HCC, and lots of mutations of p53 result in reduction of p53 perform.
