(a) Bioinformatics pipeline used to screen the candidate genes among the differentially expressed genes. (b) The three mRNA levels for FN1, CCND2, and ITGB8 on the gene chip. (c) RT-qPCR analyses of FN1 in the A2780 and OVCAR3 cells. GAPDH was used for normalization. Right, melting curves using the real-time PCR target genes (FN1, CCND2, and IGTB8) and the endogenous reference gene.
