Fig. 1From: Oxidative phosphorylation activation is an important characteristic of DOX resistance in hepatocellular carcinoma cellsLow-dose DOX-induced drug resistance in hepatoma SMMC-7721 cells. a SMMC-7721 and SMMC-7721/DOX cell configuration. b Growth curves of SMMC-7721 and SMMC-7721/DOX cells c Change in cell viability induced by different concentrations of DOX. d Immunofluorescence staining for P-gp with polyclonal mouse anti-P-gp minigene (green). Nuclear DNA was stained with DAPI (blue). DOX showed red fluorescence. Merge, maximum projectionBack to article page
