Mares with endometrosis exhibit histological changes not only in the endometrium but also in the myometrium that suggest possible functional impairment. The molecular background of these changes is not well understood. We hypothesize that the transcriptomic profile of the mare myometrium varies depending on the degree of endometrosis in mares.

The Burro de Miranda is an endangered donkey breed. The dynamics of the immune system of the donkey's reproductive tract are essential to manage the fertility of these animals for the improvement and survival of the species. In mares, high numbers of immune cells infiltrating the endometrium promote endometrosis, which is still to be confirmed in jennies.

Equine endometrosis is a major cause of infertility in mares and is characterized by degenerative, functional and fibrotic changes in the endometrium with increased collagen (COL) deposition. Transforming growth factor (TGF)-β1 is one of the major pro-fibrotic factors involved in the excessive deposition of extracellular matrix (ECM) components in the equine endometrium. It has been demonstrated that ovarian steroids, specifically 17β-estradiol (E2) and progesterone (P4), not only regulate the cyclicity of the estrous cycle, but also have been implicated as anti- or pro-fibrotic factors.

Introduction: Prostaglandins (PG) are important regulators of the myometrial contractility in mammals. Endometrosis, a condition characterized by morphological changes in the equine endometrium, also affects endometrial secretory function. However, it remains unclear whether and how endometrosis affects myometrial function.

Background: Endometrosis (chronic degenerative endometritis) results in morphological changes in the equine endometrium and impairs its secretory function. However, the effect of this condition on the myometrium remains unclear. Lysophosphatidic acid (LPA) may affect female reproductive function and embryo transport by influencing uterine contractility through its receptors (LPARs).
