Aglepristone, a competitive progesterone antagonist, is successfully used in various progesterone-dependent conditions. This study investigated uterine histomorphometric analysis, and expressions of the oestrogen α receptor (ERα) and progesterone receptor (PR) in uteri of bitches following the single dose of aglepristone treatment. Twelve client-owned healthy diestrous bitches were used in the study. The single dose of aglepristone (Alizine®, 10 mg/kg) was injected subcutaneously 5 days before ovariohysterectomy in the treatment group (n = 6); bitches without treatment served as a control group (n = 6). Uteri were collected for histomorphometric analysis, ERα and PR gene, and protein expressions studies. The mRNA expressions of ERα and PR were determined by RT-qPCR. Immunohistochemical analysis was used to evaluate the ERα and PR protein expressions using an H-score in five parts of the uterus. The results demonstrated glandular epithelium height significantly decreased (p < .05) and ERα mRNA increased (p < .01) in treated dogs. Of the treated bitches, lower expression levels of ERα were observed in the luminal epithelium, crypt and glandular epithelium, with higher expression in the endometrial stroma and myometrium (p < .05); however, PR expression decreased in the luminal epithelium, crypt and glandular epithelium (p < .01). In conclusion, reduction of the uterine glandular epithelium and ERα mRNA upregulation together with changes in ERα and PR expressions were observed in the treated bitches. However, changes in uterine ERα and PR expressions in the treated bitches depended on tissue layers. The treatment had no effect on serum oestradiol and progesterone levels. 相似文献
