Interleukin 1 regulates its own receptors in human endometrial cells via distinct mechanisms.

I-34: Steroid Hormone Signalling at the FetomaternalInterface

Background: Progesterone is indispensable for differentiation of human endometrial stromal cells (HESCs) into decidual cells, a process that critically controls embryo implantation. However, HESCs also abundantly express androgen receptors (AR), yet the role of this member of the superfamily of ligand-dependent transcription factors in the decidual process remains poorly elucidated. Materials a...

Human chorionic gonadotropin and growth factors at the embryonic-endometrial interface control leukemia inhibitory factor (LIF) and interleukin 6 (IL-6) secretion by human endometrial epithelium.

BACKGROUND The elucidation of the molecular mechanisms by which the embryo contributes to its implantation is an area of extensive research. The main objective of this study was to investigate the pattern of leukemia inhibitory factor (LIF) and interleukin-6 (IL-6) secretion by human endometrial epithelium, and their regulation by human chorionic gonadotropin (hCG) and other growth factors pres...

Adiponectin Effect on The Viability of Human Endometrial Stromal Cells and mRNA Expression of Adiponectin Receptors

بررسی ایمونوهیستوشیمی بروز گیرنده‌های استروژن و پروژسترون در انواع هیپرپلازی و کارسینوم آندومتریویید آندومتر

Background: Endometrial carcinoma (EC) is the most common gynecologic malignancy however, mechanisms underlying its pathogenesis remain obscure. Endometrial carcinoma has been classified into two major categories: type I (related to estrogen or endometrioid adenocarcinoma) and type II (unrelated to estrogen). Estrogen is the main trigger for the abnormal proliferation in the endometrial epithel...

Imbalance in the expression of the activating type I and the inhibitory type II interleukin 1 receptors in endometriosis.

BACKGROUND The ectopic establishment and progression of endometrial tissue is dependent upon its interaction with and responsiveness to the stimuli present in its new environment. Immune cell-derived cytokines, such as interleukin 1 (IL1), may alone or in concert with estrogens enhance the capability of ectopic endometrial cells to implant and develop into the host tissue. The objective of this...
