FIGURE 6.

Expression of the progesterone receptor (PGR), growth regulation by estrogen in breast cancer 1 (GREB1), and natriuretic peptide C (NPPC) mRNA were evaluated by qRT-PCR in Ishikawa cells treated for 6 hr with vehicle or low-dose combinations of (A) 1 nM BHT and DEA or (B) 1 nM or 10 nM PCE and MDEA. Values were normalized to the reference gene peptidylprolyl isomerase B (PPIB) and set relative to vehicle. Bar graphs represent means of at least five biological replicates ± SEM. *p<0.05, **p<0.01 as determined by ANOVA with Tukey’s post-hoc analysis.
