WebFurthermore, H2O2 significantly up-regulated the expression levels of SOD-2, CAT, GPx and NRF2, and modulated miR-146a and miR-34a gene expression. The same analyses were carried out after pre-treatment with taurine, a known antioxidant substance, which, in our experience, counteracted the H2O2-induced effect. WebFollowing normalization of miRNA expression to a reference gene (e.g. RNU44), we than calculate the fold change increase in expression of the miRNA of interest in the experimental group (e.g. lentivirus over-expressing miR-138) compared to the control group (lentivirus over-expressing the non-silencing, NS, RNA).
