Role of miR-500a-5p in the response to oxidative stress. (a) MCF-7 and T47D cells were exposed to increasing concentrations of H2O2 within their respective sublethal range. RNA extracted under these conditions was reverse-transcribed and tested for expression of miR-500a-5p guide strand (upper panels), and miR-500a-3p passenger strand (bottom panels). (b) Two selected targets of miR-500a-5p (i.e. TXNRD1 and NFEL2L) were studied under the same experimental conditions. (*) indicates P value < 0.05.
