Full textResumo: Diferentes tratamentos hormonais com a utilização de estrógenos e progestágenos são comumente utilizados para aumentar a oferta de receptoras nos programas de TE. Porém, pouco se sabe sobre a ação destes hormônios na expressão gênica e proteica dos receptores endometriais de estrógeno e progesterona em éguas acíclicas. O presente estudo teve como objetivo avaliar os efeitos de três tratamentos hormonais utilizados durante a preparação de éguas acíclicas sobre o edema, tônus uterino e expressão gênica e proteica de receptores de estrógeno e progesterona endometriais. Éguas em anestro foram divididas em três grupos: Dose Total 10 mg BE+P4, (n=7), Dose Total 5 mg BE+P4 (n=7), Priming Hormonal (n=7) e comparadas com o grupo de éguas cíclicas (n=7). Foram avaliados: a expressão proteica e gênica relativa dos transcritos para os receptores de estrógeno e progesterona presentes no endométrio por meio das técnicas de imunohistoquímica e RT-qPCR; e as características morfológicas do útero por palpação retal e ultrassonografia em modo B. Os tratamentos hormonais utilizados no presente estudo foram eficazes em promover edema e tônus uterinos semelhante ao que ocorre em éguas cíclicas. Adicionalmente, o grupo Priming Hormonal demonstrou induzir características uterinas similares as observadas nos grupos 5 mg BE+P4 e no grupo controle, após 14 dias de intervalo. O tratamento hormonal com dose total de 10 mg de BE+P4 LA utilizando para o preparo de éguas acíclicas, demonstrou ser similar ... (Resumo completo, clicar acesso eletrônico abaixo)
Abstract: Different hormonal treatments with the use of estrogen and progestogen are commonly used to increase the supply of receiving the TE programs. However, little is known about the effect of these hormones on gene and protein expression of endometrial receptors for estrogen and progesterone in non-cyclic mares. This study aimed to evaluate the effects of three hormonal treatments used for the preparation of non-cyclic mares on the edema and uterine tone and gene and protein expression of estrogen and endometrial progesterone receptors. Mares anestrus were divided into three groups: total dose 10 mg EB + P4 (n = 7) total dose 5 mg EB + P4 (n = 7) Hormonal Priming (n = 7) and compared with the group of cyclic mares (n = 7). Were evaluated: protein expression and gene transcripts related to the estrogen and progesterone receptors present in the endometrium by the techniques of immunohistochemistry and RT-qPCR; and the morphological characteristics of the uterus by rectal palpation and ultrasound in B mode. Hormonal treatments used in this study were effective in promoting edema and uterine tone similar to what occurs in cyclic mares. Additionally, the Hormonal Priming group demonstrated induce uterine similar characteristics observed in the groups 5 mg EB + P4 and control group, after 14 days apart. Hormonal treatment with a total dose of 10 mg EB + P4 LA using for the preparation of non-cyclic mares, was shown to be similar in tone and uterine edema, protein expression and relative...

Full textThe aim of this study was to demonstrate the presence and localization of gonadotropic and steroid hormone receptors, in different tissues of the mare genital tract and the different reactivity to these receptors during the endometrial cycle and physiologic anestrus. Another objective was to compare the reactivity to theses receptors in mares with and without endometrosis. Immunohistochemistry was performed using the peroxidase anti-peroxidase technique (PAP). Uterus, cervix and oviduct of 41 criollo mares were collected in an abattoir. There was variation in the intensity of the staining and distribution for estrogen receptors (PR), progesterone receptors (PR) and luteinizing hormone receptors (LHR) with the endometrial cycle and different tissues. The endometrial surface epithelial cells were stained strongly for ER and PR in the estrous and dioestrus; glandular epithelial cells, stromal cells and smooth muscle cells of the myometrium had moderate staining for ER and PR during these two phases and in anestrus too. The immunoreactive score for LHR in the surface epithelial cells during endometrial cycle was weak to moderate but, in general, strong staining was observed in dioestrus. More weak staining intensity was observed in the glandular epithelial cells than luminal epithelial cells. Smooth muscle cells of the myometrium showed weak staining for LHR throughout the endometrial cycle. During the anestrus, the immunoreactivity score was weak in the surface epithelial cells. In general, the glandular epithelium was not stained. Myometrium cells were weak to not staining for LHR, in this phase. In this study there was no significant difference in immunoreactive score for ER, PR and LHR in endometrium with or without endometrosis but fibrotic glands showed different expression patterns of ER, PR and LHR, could evidence for functionally glandular maldifferentiation in endometrosis. The cervical epithelial surface, stromal cells and smooth muscle cells were moderate to strongly staining for ER and PR, with little variation throughout the endometrial cycle but the immunorectivity was strongest during the anestrus in muscular and stromal cells. Surface epithelial cells of cervix were weak to moderate stained for LHR; smooth muscle cells showed weak staining for these receptors. There was no variation during cycle. In the oviduct, epithelial, stromal and muscle cells showed reactivity for RE and RP, during cycle and anestrus. Epithelial cells were moderate to strongly staining for these receptors, with evident irregularity in different types of cells. Apparently ciliated epithelial cells were stained but the intensity was much less than that observed in nonciliated epithelial cells, probably reflecting different functions of these cells. Stromal cells showed moderate staining during dioestrus and strongest reactivity in estrous and anestrus; muscle cells showed strong reactivity for ER throughout the cycle. The reactivity for LHR was weak to moderate throughout the cycle in the epithelial cells and weak in the muscle cells. During anestrus only three strains of muscle cells showed reactivity for LHR. In dioestrus the intensity was strongest. These findings evidence for the firs time the presence for LHR in extra-gonadal reproductive organs of mare. Though there were reports of ER and PR expression in equine endometrium, this is the first report of localization of these receptors in cervix and oviduct of mare using immunohistochemistry. It was found marked individual variation among the strains. These results probably were caused by the variation among the day of cycle and the complexity of mechanisms involved in the presence of these receptors. The findings of the present study allow us to infer that the ovarian steroid hormones nad LH function through their receptors in different tissues of mare reproductive tract, can help us to elaborate new strategies to improve the reproductive efficiency in this specie.
