Studies have demonstrated that adiponectin could be a link between reproductive functions and energy metabolism in animals. The aim of the present study was to investigate the effects of prostaglandin (PG) E2 and PGF2α (10, 50, 100, 250 and 500ngmL-1) on the expression and secretion of adiponectin and its receptor genes and proteins by cultured in vitro porcine endometrial and myometrial tissue...
Although regulation of angiotensin II receptor (AT) binding in vascular and uterine smooth muscle is similar in nonpregnant animals, studies suggest it may differ during pregnancy. We, therefore, examined binding characteristics of myometrial AT receptors in nulliparous (n = 7), pregnant (n = 24, 110-139 d of gestation), and postpartum (n = 21, 5 to > or = 130 d) sheep and compared this to vasc...
BACKGROUND The transcription factor, octamer-binding transcription factor 4 (OCT4)/POU5F1, is expressed in embryonic stem cells, germ cells and some types of adult stem cells. Human OCT4 encodes two isoforms, OCT4A and OCT4B. While OCT4A plays a crucial role in the maintenance of stem cell properties, including pluripotency, whereas OCT4B does not. We previously reported that human myometrium c...
Paracrine activation of WNT/β-catenin pathway in uterine leiomyoma stem cells promotes tumor growth.
Uterine leiomyomas are extremely common estrogen and progesterone-dependent tumors of the myometrium and cause irregular uterine bleeding, severe anemia, and recurrent pregnancy loss in 15-30% of reproductive-age women. Each leiomyoma is thought to arise from a single mutated myometrial smooth muscle stem cell. Leiomyoma side-population (LMSP) cells comprising 1% of all tumor cells and displayi...
Human myometrial contraction plays a fundamental role in labor. Dysfunction of uterine contraction is an important cause of labor progression failure. Although the mechanisms controlling uterine contraction are not completely understood, intracellular Ca2+ mobilization plays an important role during uterine contraction. Several mechanisms of intracellular Ca2+ mobilization are present in smooth...
BACKGROUND Gap junctions increase in size and abundance coincident with parturition, forming an intercellular communication network that permits the uterus to develop the forceful, coordinated contractions necessary for delivery of the fetus. Lindane, a pesticide used in the human and veterinary treatment of scabies and lice as well as in agricultural applications, inhibits uterine contractions...
Thompson, Michael, Hosana Barata da Silva, Weronika Zielinska, Thomas A. White, Jeffrey P. Bailey, Frances E. Lund, Gary C. Sieck, and Eduardo N. Chini. Role of CD38 in myometrial Ca transients: modulation by progesterone. Am J Physiol Endocrinol Metab 287: E1142–E1148, 2004. First published August 31, 2004; doi:10.1152/ajpendo.00122.2004.—Oxytocin-induced Ca transients play an important role i...
A case of laparoscopic excision of a rudimentary horn is presented. The anatomical features of this case are contrasted with others in the published literature. A 23 year old nulligravida presented with severe dysmenorrhoea and a pelvic mass. At laparoscopy a unicornuate uterus with a rudimentary horn was identified. The patient had stage III endometriosis. The rudimentary horn was attached to ...
OBJECTIVE To evaluate the accuracy of antenatal sonographic measurement of lower uterine segment (LUS) thickness in the prediction of risk of uterine rupture during a trial of labor (TOL) in women with a previous Cesarean section (CS). METHODS PubMed and EMBASE were searched to identify articles published on the subject of sonographic LUS measurement and occurrence of a uterine defect after d...
