Densitometric summary, expressed as the ratio of mRNA for mineralocorticoid receptor (MR) (top), 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) (middle), and 11β-HSD2 (bottom) to that of glyceraldehyde-3-phosphate dehydrogenase (GAPDH) in rat ovaries (on days 1–4 of the estrus cycle), super-ovulated ovaries, colon, and kidney. Estrus cycles of the rats were synchronized with luteinizing hormone-releasing hormone (LHRH), and ovaries were taken at day 1 (early diestrus), day 2 (late diestrus), day 3 (estrus), and day 4 (late estrus). Sup-Ov: super-ovulated ovaries taken from rats 8–12 hr after coitus after super-ovulation induced by the administration of LHRH (40 μg/rat; ∼200 μg/kg on day 4), pregnant mare serum gonadotropin (300 IU/kg on day 2), and human chorionic gonadotropin (300 IU/kg on day 0). Col: colon; Kid: kidney. Error bars represent standard error of the mean. *Denotes significance compared with the values of mRNA from super-ovulated ovaries.
