Estrogen and progesterone receptor isoforms expression in the stomach of Mongolian gerbils

Figure 1 Estrogen and progesterone receptor isoforms expression in gastric tissue. PR isoforms and ER-alpha expressed in gerbil tissues are similar to those present in rats. Ovariectomized adult female gerbils were treated with subcutaneous injections of vehicle (VEH), 17-beta-estradiol (E2) alone and E2+ progesterone (E2 + P4). Gastric antrum lysates were immunoblotted with commercially available antibodies for ER-alpha, and PR. Equally treated rat tissues were used as positive control. The images show representative blots of gastric antrum of rat and gerbil.

Figure 2 Sex steroid receptors content in gerbil uterus. PR isoforms (A) and ERα (B) in gerbil uterine lysates is shown. Ovariectomized adult female gerbils were treated with subcutaneous injections of VEH, E2 and E2 + P4. Receptors were detected by immunoblotting and content was adjusted to alpha-tubulin expression (n = 5). Data are mean ± SE.

Figure 3 Sex steroid receptors content in gerbil gastric antrum. PR isoforms (A) and ER-alpha (B) in gerbil gastric antrum lysates is shown. Ovariectomized adult female gerbils were treated with subcutaneous injections of VEH, E2 and E2 + P4. Receptors were detected by immunoblotting and content was adjusted to alpha-tubulin expression (n = 5). Data are mean ± SE.

Figure 4 Sex steroid receptors content in gerbil gastric corpus. PR-A (A) and PR-B (B) ER-alpha in gerbil gastric corpus lysates is shown. Ovariectomized adult female gerbils were treated with subcutaneous injections of VEH, E2 and E2 + P4. Receptors were detected by immunoblotting and content was adjusted to alpha-tubulin expression (n = 5). Data are mean ± SE. ^aP < 0.05 vs VEH and E2 + P4.
