BACKGROUND SERPINE2, also known as protease nexin-1, belongs to the serine protease inhibitor (SERPIN) superfamily. It is one of the potent SERPINs that modulates the activity of plasminogen activators (PAs). PAs and their SERPIN inhibitors, such as SERPINB2 and SERPINE1, were expressed in the human endometrium and were implicated in implantation. However, expression data about SERPINE2 in the ...

We examined the localization of oestrogen receptor (ER) β mRNA in the human endometrium throughout the menstrual cycle using non-radioactive in-situ hybridization with Brigati-tailed oligonucleotides. The findings were compared with those of ERα in order to examine the possible biological significance of ERβ in the human endometrium. Both ERα and ERβ mRNA expression were detected in all major h...

Calina papaya leaf is an Indonesian plant type that has the potential to be used as a medicinal plant. Phytochemical compounds found in leaves act antifertility agents. The research aimed study effect of ethanol extract on estrus cycle and uterine morphology wistar rats. experiment lasted 30 days involved 25 female treatment consisted 5 groups, namely K (distilled water), K+ (contraceptive pill...

Rhythmic peristaltic contractions of the muscular wall of the non-pregnant uterus can be demonstrated throughout the menstrual cycle, with a maximum just before ovulation. However, not only during the follicular phase but also during the luteal phase, the uterus shows remarkable contractile activity. The present study was conducted in order to examine uterine peristaltic activity and its functi...

In a total of 41 endometrial tissue samples, the relationship between telomerase activity and proliferating cell nuclear antigen (PCNA) labelling index was studied. In samples of endometrium from the proliferative phase of the menstrual cycle, telomerase activity was found in 15 out of 17 cases (88%). Two samples from the early proliferative phase showed negative telomerase activity and a low P...

Abstract In cows embryo transfer occurs on the 7 th day of oestrous cycle. Embryo survival and successful pregnancy depend many factors, including early interaction between endometrium. Therefore, aim our research was to describe histo-morphological characteristics endometrium in donor recipient obtaining day, respectively (7 oestrus cycle). addition, progesterone oestradiol levels, ipsilateral...

Background: Epigenetic aberration such as DNA methylation and histone modifications appear to be involved in various diseases such as Endometriosis. Here, we investigated the epigenetic regulation of HOXA10 promoter, as a crucial gene, responsible for uterine organogenesis, functional endometrial differentiation and endometrial receptivity, and its correlation with mRNA expression of this gene ...

BACKGROUND During the estrous cycle, the rat uterine endometrium undergoes many changes such as cell proliferation and apoptosis. If implantation occurs, stromal cells differentiate into decidual cells and near the end of pregnancy, a second wave of apoptosis occurs. This process called decidual regression, is tightly regulated as is it crucial for successful pregnancy. We have previously shown...

BACKGROUND Endometrium is a unique tissue that is prepared for implantation of blastocyst during each menstrual cycle. In humans, if implantation does not occur or fails, endometrium is shed. METHODS AND RESULTS We identified ebaf/lefty, as a key cytokine, highly expressed in human endometrium during the non-receptive phase of tissue remodelling. Lefty was increased in the endometria of a num...
