Fig. 2From: Analysis of MDR genes expression and cross-resistance in eight drug resistant ovarian cancer cell linesGene expression analysis. Expression (Q-PCR) of MDR1 (a), MRP1 (b), MRP2 (c), BCRP (d), and LRP (e) genes. The figure presents relative gene expression in resistant cell lines (grey bars) with respect to the A2780 cell line (white bars) assigned as 1. Values were considered significant at *P < 0.05, **P < 0.01 and ***P < 0.001Back to article page
