Immunostaining of c-fos and PRL in human endometrium (A) c-fos proliferative/placebo. (B) c-fos secretory/placebo. (C) c-fos secretory/MPA. (D) PRL proliferative/placebo. (E) PRL secretory/placebo. (F) PRL secretory/MPA. Specific immunostaining is indicated by the brown color in the nuclei (A) and citosol (E, F). Original magnification: ×400.

3. FIGURE 2
Percentage of patients with endometrial samples that showed positive immunostaining for c-fos (A) or PRL (B) on epithelial and stromal cells. ∗P<.05 vs. proliferative/placebo (Fisher’s exact test). MPA = medroxyprogesterone acetate; PRL = prolactin.

4. FIGURE 3
Percentage of patients whose endometrial samples showed positive immunostaining for c-fos (A) or PRL (B) on epithelial (open bars) and stromal (hatched bars) cells according to endometrial biopsy dating. EP = early proliferative; MP = midproliferative; ES = early secretory; MS = midsecretory; LS = late secretory. Serum E2 levels and progesterone/E2 ratios of patients from each endometrial phase are expressed as medians (C). • = progesterone/E2; ○ = E2.

5. FIGURE 4
Reverse transcription–polymerase chain reaction product visualized in agarose gel stained with ethidium bromide. Lanes 1–7 = proliferative/placebo; lanes 8–13 = secretory/placebo; lanes 14–18 = secretory/MPA. N = negative control. Quantitative results are expressed in relation to β2-microglobulin optical density (arbitrary units) and plotted as medians plus 75th percentiles. ∗P<.05 vs. proliferative/placebo (Dunn’s test). MPA = medroxyprogesterone acetate; PRL = prolactin; bp = base pair.

Correlation between c-fos mRNA in the endometrium and serum E2 levels (A) and progesterone/E2 ratios (B). r = Spearman rank correlation coefficient). MPA = medroxyprogesterone acetate; mRNA = messenger RNA.
