Expression of DNA repair enzymes in MCF-7 and MCF-10A cells treated with TH and OHT. The expression of Rad51, Ku70 and Ku80 in the cells was determined by Western blotting following 24 hr exposure to OHT (10 μM), TH (1%) or their combination. The protein bands were visualized using an image analyzer and band density was analysed using ImageJ software with fold-change difference of expression compared to untreated cells (UT) written below each band.
