Gene expression analyses and platinum resistance in tumoral samples from ovarian cancer patients. Gene expression analyses by RT-qPCR of C-KIT, CD133, NANOG, CXCR4 and ABCG2 in non-tumoral and tumoral samples from ovarian cancer patients, resistant or sensitive to platinum treatment. The average and SD of three independent experiments are shown. Statistical significance was assessed using the Student’s t-test. *, P < 0.05; **, P < 0.01; ***, P < 0.001
