P4 mediated time-dependant gene expression in RL95-2 (blue) and HEC1A (red) cell lines compared to non-treated samples. Expression profiles of FOXA2, NCOA1, TBX19 and TNC genes had significant difference (p < 0.05, two-tailed, unpaired Student's t-test with 95% confidence of log2-transformed expression ratios relative to baseline expression) in mRNA expression ratios (*) between RL95-2 and HEC1A cells after P4 treatment. P4 mostly induced mRNA level in RL95-2 cells but down-regulated in HEC1A cells.
