miR-23 is a putative regulator of TrxR1 expression during skeletal muscle differentiation. (a) RT-qPCR analysis showing the relative expression of TrxR1 mRNA in proliferating (GM) versus differentiating (DM) C2C12 cells collected at 1, 2, 3 and 5 days. Data were normalised to Cyclophilin A expression and represented as mean ± SEM of three independent experiments. (b) Relative expression of TrxR1 mRNA in proliferating (GM) versus differentiating (DM) satellite cells, measured by RT-qPCR and normalized to GAPDH expression. (c) Putative miR-23a and b binding sites in the 3′ UTR of TrxR1 mRNA. (d) RT-qPCR analysis displaying miR-23a andmiR-23b expression (normalized to U6 snoRNA) in C2C12 proliferating (GM) versus differentiating (DM) cells. Data are exposed as mean ± SEM of three experiments. The normalised GM values of each miRNA were set = 1.
