About the Edition

Ischemic cardiomyopathy is a leading cause of mortality in North America. Although advances in current treatments have been significant in improving myocardial perfusion, many patients still cannot be treated properly. Thus, new therapies need to be developed. Since angiogenesis occurs naturally in the female reproductive tract, the cells from the uterine tissue may be ideal candidate cells to induce angiogenesis, which could be further enhanced through estrogen stimulation. My in vitro dose-response and time course demonstrated that estrogen did not regulate vascular endothelial growth factor (VEGF) protein levels in cultured uterine cells. However, an in vivo study demonstrated that transplantation of cells with or without estrogen increased blood vessel formation. The data suggests that signals mediated by cells and/or estrogen may induce larger vessel formation.

Apr 26,  · The angiogenic peptide adrenomedullin (ADM) has been implicated as a mediator of the increased risk of endometrial hyperplasia and cancer resulting from the use of tamoxifen for the treatment and prevention of breast shareholderdemocracy.com by: Objective. To determine tissue concentrations of E 2, estrone, P, and estrogens metabolites (EMs) 2-methoxyestradiol, 2-methoxyestrone, 4-hydroxyestrone, and ketoestradiol in corpus luteum (CL) of different ages, and after hCG administration; and to examine the effects of EMs on vascular endothelial growth factor (VEGF) secretion and angiogenic activity released by cultured luteinizing Cited by:

Vascular endothelial growth factor (VEGF) is a potent angiogenic and prognostic factor for many tumors, including those of endocrine-responsive tissues such as the breast and uterus. Recent studies indi-cate that 17 -estradiol (E2) modulates VEGF expression in breast and uterine cells, involving transcriptional activation through estrogenCited by: Jan 01,  · It is well known that many diseases and pharmaceutical compounds may influence the menstrual cycle and the endometrium. It has been shown that uterine pathology can cause an abnormal expression of different angiogenic growth factors and growth factor receptors (Kooy et al., ; Anania et al., ; Sangha et al., ).Cited by:

Dec 30,  · Studies show that E2, through its receptors, either on uterine cells or uterine endothelium has rather promoting effect on angiogenesis, causing increased VEGFA and VEGFR2 expression [37, 38]. There is less studies concerning the localisation and expression of oestrogen receptors in endothelial cells in ruminant uterus [ 2 ].Author: Martyna Lupicka, Anna Zadroga, Agata Szczepańska, Anna Justyna Korzekwa. Jan 01,  · Whereas the exact effects of estrogen appear to be context-dependent, our results provide concrete evidence that —besides the stimulatory effect on the expression of pro-angiogenic regulators such as VEGF—estrogen may also function on alternative targets such as the antiangiogenic factor Cited by: 8.

Oct 01,  · On the basis of the results of the current study and of other in vitro and in vivo studies, we suggest that estrogen, by regulating expression and secretion of angiogenic factors such as VEGF by glandular epithelial cells of the endometrium, regulates endometrial microvascular endothelial cell tube formation and thus shareholderdemocracy.com by: We propose that estrogen, by regulating expression and secretion of angiogenic factors such as VEGF by glandular epithelial cells of the endometrium, regulates endometrial angiogenesis.

Do you. Although VEGF‐A can be detected in the decidual stroma, VEGF‐A production by uNK cells is minimal. VEGF‐A is the best‐characterized, angiogenic growth factor with major effects on endothelial cell proliferation and motility, as well as inducing vascular shareholderdemocracy.com by: Estrogen Receptor ER alpha and beta stimulation by Estrogen increases Vascular Endothelial Growth Factor secretion by Uterine Artery Endothelial.

Dec 23,  · The effects of local estrogen on connective tissue components, however, have been less well characterized. The purpose of this study was to use the rat as an animal model to compare the effects of systemic and local estrogen treatment on collagen content and expression of proteins involved in collagen assembly in the vaginal shareholderdemocracy.com by: In line with this issue, early studies showed that, estrogen induces the expression of vascular endothelial growth factor in ovaries and uterine tissue (18, 38).

Thus, we can conclude that PGN. Aug 22,  · The NK cells are the principal immune cells present during the WOI and are important for immune tolerance, angiogenesis, trophoblast migration, and invasion. 68 The NK cells produce pro-angiogenic factors such as VEGF and placental growth factor, which regulate maternal–uterine vasculature remodeling and trophoblast invasion.

69,70 Mice Cited by: 7. Estrogen produces its effects by binding to estrogen recep-tors (ER) in the reproductive organs. It has been reported that estradiol increases the extracellular levels of VEGF in breast cancer in vivo, which suggest that VEGF expression in the breast is, at least in part, modulated by ER for which the VEGF gene is a target (7).

In the present study, we developed a co-culture of human endometrial cells and microvascular endothelial cells to determine whether the regulatory role shown for estrogen on endometrial angiogenesis in vivo in the non-human primate would be demonstrable.
