Representative ethidium-bromide–stained polyacrylamide gel of reverse-transcribed ER and PR mRNA coamplified by PCR from Ishikawa cells (Ish), human endometrium (Endo), and human ovary (Ov). The expected products from the ER and PR migrate at 380 and 535 bp, respectively.

3. Figure 2
Effect of levonorgestrel, MPA, norethindrone, and 17β-E2 on VEGF 165 isoform abundance using cpm ratios vs. β-actin. Relative abundance of VEGF 165 mRNA from control and three different concentrations of levonorgestrel (LNG), MPA, norethindrone (NET), and 17β-E2 (E2) are indicated. Results are expressed as means ± SE. *P<.05 as compared with the control group. ±P<.05 as MPA at 1.0 μM is compared with E2 at 1.0 μM. **P<.05 as norethindrone at 1.0 μM is compared with E2 at 1.0 μM.
