Allograft inflammatory factor-1 (AIF-1) is a cytokine originally identified in rat cardiac allografts with chronic rejection. AIF-1 is expressed in various human immune-related tissues and is thought to play a role in inflammatory responses…

Uterine movement is suggested to play roles in various events related to the uterus. In view of the current concept underscoring the biological implications of mechanical stretch, we speculated that the mechanical stretch exerted by uterine…

During the secretory phase of the menstrual cycle, a natural killer (NK) cell subset expressing cluster of differentiation (CD)56bright appears in the decidualizing uterus and remains until onset of menses. If pregnancy occurs, decidual NK …

The present clinical study was conducted to investigate the effectiveness of a daily dose of 40 mg mifepristone in preventing premature LH surges in women undergoing controlled ovarian hyperstimulation (COH) for in vitro fertilization and t…

Endometriosis is known to be associated with local inflammatory reactions. Given the emerging concept of thrombin and its specific receptor, protease-activated receptor 1 (PAR1), as important players in inflammation and cell proliferation, …

The elevation of the proinflammatory chemoattractant cytokine levels in ectopic and eutopic endometrium of endometriosis implies an inflammatory basis for this disease. The relationship between endothelial cells and leukocytes is likely to …

Various matrix metalloproteinases (MMPs) participate in the menstrual breakdown of the human endometrium. MMP-9/gelatinase B is proposed as a major factor because it degrades many extracellular matrix constituents, including in the vasculat…

To evaluate the involvement of platelet-derived growth factor (PDGF) isoforms (PDGF-AlphaAlpha, PDGF-AB, and PDGF-BB) on endometrial tissue remodeling during the perimenstrual period, we investigated the effects of PDGF on the proliferation…

CONTEXT: The nuclear factor-kappaB (NF-kappaB) pathway is a critical mediator of RANTES (regulated on activation, normal T cell expressed and secreted) gene regulation and therefore represents a potential target for therapy of endometriosis…

OBJECTIVE: Endometriosis, a common disease among women of reproductive age, is characterized by the presence of endometrial-like tissue outside the uterus. TNF-alpha induces IL-8 production in endometriotic cells through nuclear factor-kapp…

IL-11 signaling is critical for decidualization of the endometrial stroma in early pregnancy in the mouse. In this study, we investigate the function of IL-11 signaling in cAMP-induced decidualization of human endometrial stromal cells. We …

CONTEXT: Fertility is dependent on a functioning corpus luteum, the formation of which is associated with intense angiogenesis. The role of angiogenic factors, such as vascular endothelial growth factor (VEGF), in luteal function has yet to…

It is known that angiogenesis is of pivotal importance for the development of endometriosis. However, in the treatment of endometriosis patients, prevention of endometriosis lesion development only will not be sufficient as a therapy. Treat…

Proline-, glutamic acid-, and leucine-rich protein-1)PELP1/MNAR [modulator of nongenomic activity of estrogen receptor (ER)], a novel coregulatory protein, modulates genomic as well as nongenomic activity of ERs. We characterized the expres…

To evaluate the involvement of chemokines in the pathogenesis of endometriosis, we investigated the expression of CXC chemokines in cultured ovarian endometriotic cyst stromal cells (ECSC), endometrial stromal cells with endometriosis (ESCw…

EMX2 is a transcription factor necessary for reproductive tract development. Sex steroids regulate endometrial HOXA10 expression, which in turn negatively regulates EMX2. In this study, we characterize menstrual cycle-dependent expression o…

Endometrial stromal cells reportedly have a role in the initial invasion of endometrial tissue into the peritoneum. Hepatocyte growth factor (HGF), which is a ligand for the c-met protooncogene product (Met), stimulates proliferation and in…

Peritoneal fluid macrophages (PFM) are activated in women with endometriosis, in whom they are thought to mediate or exacerbate inflammation. The effect of PFM on endometrial stromal cells (ESC) was studied using a coculture model to evalua…

Endometriosis is a disease in which the lining of the uterus (endometrium), shed at the time of menstruation, becomes established at sites such as the peritoneum and ovaries. These explants develop a rich blood supply that enables them to s…

In all species studied, the basic fibroblast growth factor (bFGF) gene is transcribed into multiple mRNAs, one of which is an antisense RNA (1B FGF-AS) probably involved in regulating the stability of the sense transcript. In this study we …

Fibroblast growth factor-9 (FGF-9) is a steroid-regulated mitogen and survival factor for nerve and mesenchymal cells. In the current study, we determined the expression pattern and functional roles of FGF-9 in the ectopic endometriotic les…

Follistatin-related gene (FLRG) encodes a novel secreted glycoprotein that is highly homologous to follistatin and binds activins and bone morphogenetic proteins, members of the TGF beta superfamily of growth/differentiation factors. FLRG p…

TAK-013 is a novel nonpeptide and orally active GnRH antagonist. We first examined the effect of TAK-013 on GnRH-stimulated LH release using primary-cultured pituitary cells of cynomolgus monkeys. TAK-013 suppressed LH release to below basa…

Human endometrium expresses TGF-beta and TGF-beta receptors where they regulate several endometrial biological activities implicated in embryo implantation, irregular bleeding, endometriosis, and cancer. In the present study, we determined …

Endometriosis, a common disease among women of reproductive age, is characterized by the presence of endometrial-like tissue outside the uterus. We previously reported that TNFalpha promoted proliferation of endometriotic stromal cells by i…
