Relative ABCB1 expression in lymphoblastoid and ovarian cancer cell lines.
ABCB1 mRNA expression was measured by quantitative RT-PCR in (a) 19 lymphoblastoid cell lines and (b) 10 ovarian cancer cell lines. All results were expressed relative to the level expressed in OVCAR-3. The expression in SK-OV-3, A2780 and OVCAR-3 in (a) were measured in parallel to compare the levels of relative expression between lymphoblastoid cell lines and ovarian cancer cell lines. The results presented were the geometric mean of values normalized to the three control genes HPRT, GUSB and PGK1.
