Transcriptional activity of SCF detected by a reverse transcription-quantitative polymerase chain reaction, and protein expression levels detected by enzyme-linked immunosorbent assay in the OVCAR8 cell line. (A) mRNA expression levels of SCF, which were significantly inhibited at 48 (P=0.008) and 72 h (P=0.005). (B) Protein expression levels of SCF, which were not significantly inhibited at 48 h (P=0.101) but were significantly inhibited at 72 h compared with the control group (P=0.036). *P<0.01 vs. the control. SCF, stem cell factor.
