Fig. 2From: Cellular effects induced by 17-β-estradiol to reduce the survival of renal cell carcinoma cellsDNA repairing ability of A498 cells with treatments of etoposide and E2. A498 cells treated respectively with a etoposide (50 μM) alone or b etoposide (50 μM) and E2 (70 nM). Green, γH2AX-positive cells; blue, DAPI (4′,6-diamidino-2-phenylindole. The scale bar represented the 50 μm. E2, 17-β-estradiolBack to article page
