OBJECTIVE: To study the effect of adenomyosis on the localized expression of the GATA binding proteins 2 and 6 (GATA2 and GATA6) zinc-finger transcription factors that are involved in proliferation of hematopoietic and endocrine cell lineag…

CONTEXT: Enhanced levels of catecholestradiols, 2-hydroxyestradiol (2-OHE2) or 4-hydroxyestradiol (4-OHE2), are reported in endometriosis. During gestation, catecholestradiol activation of adrenergic receptors (AR) elevates estrogen recepto…

Research questionEndoplasmic reticulum stress (ERS) is caused by the accumulation of the misfolded or unfolded proteins in the endoplasmic reticulum and induces the unfolded protein response (UPR). Peritoneal fluid is important in the patho…

The endoplasmic reticulum (ER), comprises 60% of the total cell membrane and interacts directly or indirectly with several cell organelles i.e., Golgi bodies, mitochondria and proteasomes. The ER is usually associated with large numbers of …

BACKGROUND: Endometriosis is one of the most common chronic gynecological diseases. OBJECTIVES: The aim of the study was to examine the effects of curcumin and/or deferoxamine on cell proliferation in a rat model of endometriosis. MATERIAL …

BackgroundLocal pro-inflammatory environment and enhanced cell survival contribute to the endometriosis development. A serine/threonine kinase p38 mitogen-activated protein kinase (MAPK) mediates intracellular signaling of cytokine producti…

BackgroundAdenomyosis was found to have negative impacts on embryo implantation. Leukemia inhibitory factor (LIF), proposed to be a molecular marker for endometrial receptivity, works through the LIF receptor (LIFR) on both the embryo and t…

BACKGROUND: Human pregnancy requires robust hemostasis to prevent hemorrhage during extravillous trophoblast (EVT) invasion of the decidualized endometrium, modification of spiral arteries and post-partum processes. However, decidual hemorr…

Cytokines modulate turnover of the endometrium during the menstrual cycle and contribute to the pathogenesis of endometriosis. Gene expression for cytokines is often regulated by proteins that bind to adenosine- and uridine-rich elements (A…

Endometriosis is a common inflammatory gynecological disease characterized by the presence of endometrial tissue outside of the uterine cavity. The c-Jun N-terminal kinase (JNK) is a subfamily of the mitogen-activated protein kinases (MAPKs…

The main aim of this study is to describe the in vivo temporal and spatial expression of monocyte chemotactic protein 1 (MCP-1) in human endometrial endothelial cells (HEECs) and to compare the in vitro regulation of MCP-1 expression by sex…

Protein kinase B (PKB/Akt), a serine/threonine kinase, regulates the function of many cellular proteins involved in apoptosis and proliferation. It was postulated that there is a higher Akt activity in endometriosis compared with normal end…

Endocrine and immune systems are among the most essential regulators of endometrial physiology, and immune-endocrine interactions are likely to be involved in the pathogenesis of endometriosis. Endometriosis is an inflammatory, estrogen-dep…

Implantation, a critical step for establishing pregnancy, requires molecular and cellular events resulting in uterine growth and differentiation, blastocyst adhesion, invasion, and placental formation. Successful implantation requires a rec…

Estrogenic effects involve interactions between estrogen receptors (ERs), response elements, and nuclear proteins. It is hypothesized that interaction between ER and NF-kappa B may affect the regulation of responsive genes. Electrophoretic …

CONTEXT: Endometriosis is an estrogen-dependent disease characterized by the presence of endometrial tissue outside of the uterine cavity, causing pelvic pain and infertility in 10% of reproductive-aged women. It is unclear why ectopic endo…

Many chemokines likely contribute to the pathogenesis of endometriosis. The authors hypothesize that the broad-spectrum chemokine inhibitor NR58-3.14.3 may prevent ectopic human endometrium implantation and growth. After placing human endom…

Human endometrium is a dynamic tissue under the influence of numerous hormones, growth factors, and cytokines interacting to maintain a balance of cellular growth, differentiation, and apoptosis. We have previously demonstrated that several…

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 …

ObjectiveTo evaluate the effect of interleukin-8 (IL-8) on endometrial stromal cell metalloproteinase (MMP) activity and invasiveness.DesignExperimental laboratory study.SettingUniversity medical center.Patient(s)Reproductive age women with…

ObjectiveTo evaluate soluble Fas ligand concentrations in serum and peritoneal fluid from women with endometriosis and from fertile controls without endometriosis, and to study levels of soluble Fas ligand in conditioned media of cultured e…

Interaction between endometrial stromal cells and extracellular matrix (ECM) components has a crucial role in the development of endometriosis. Endometrial stromal cells attach to the mesothelial surface of peritoneum by means of integrins …

Numerous cytokines and growth factors are synthesized in the endometrium. IL-8 is one of these cytokines regulating endometrial function. It is a neutrophil chemoattractant/ activating factor and a potent angiogenic agent. IL-8 is elevated …

PROBLEM: Chemokines are increasingly recognized as important regulators of uterine function. METHODS OF STUDY: The following is a review of uterine chemokines, especially monocyte chemotactic protein (MCP)-1, interleukin (IL)-8, and regulat…
