BACKGROUND A good blood supply towards the endometrium is usually considered to be an essential requirement for implantation. We aimed to evaluate the role of endometrial and subendometrial blood flows in the prediction of pregnancy during IVF treatment. METHODS Patients undergoing the first IVF cycle were recruited. A three-dimensional (3D) ultrasound examination with power Doppler was perfo...

Background: Overexpression of Cyclin D1, a positive cell cycle regulator, may lead to uncontrolled cell proliferation. Aim: The present study was undertaken to examine the expression profile of Cyclin D1 in normal, hyperplastic and neoplastic endometrium and to evaluate the possibility of its role in the genesis of endometrial neoplastic and preneoplastic lesions. Settings and Design: A cross s...

Adequate growth of the endometrium is an important factor for successful implantation. Some authors have reported that there is a steady and gradual increase in pregnancy rates as endometrial thickness increases [1]. When endometrial thickness is <6 mm, the probability of achieving a full-term pregnancy decreases [2]. In order to maximize pregnancy rates, endometrial thickness from 8 mm to 14 m...

Because epigenetic alterations are believed to be involved in the repression of tumor suppressor genes and promotion of tumorigenesis in endometrial cancers, novel compounds endowed with a histone deacetylase (HDAC) inhibitory activity are an attractive therapeutic approach. In this review, we discuss the biologic and therapeutic effects of HDAC inhibitors (HDACIs) in treating endometrial cance...

Cystic endometrial hyperplasia-pyometra complex is the most frequent and important endometrial disorder encountered in bitches. The pathogenesis of the disease is related to the activity of progesterone [Feldman and Nelson, Canine and Feline Endocrinology and Reproduction (1996) W.B. Saunders, Philadelphia]. Cystic endometrial hyperplasia (CEH) is an abnormal response of the bitch's uterus to o...

Dienogest, a synthetic progestin, has been shown to be effective against endometriosis, although it is still unclear as to how it affects the ectopic endometrial cells. Decorin has been shown to be a powerful endogenous tumor repressor acting in a paracrine fashion to limit tumor growth. Our objectives were to examine the direct effects of progesterone and dienogest on the in vitro proliferatio...

Corticotropin-releasing hormone (CRH) is a hypothalamic neuropeptide that has been identified also in several peripheral tissues, including organs of the reproductive system. In man, CRH is synthesized and released by the gonads, the placenta, maternal decidua, and the epithelial endometrium. So far, CRH has been demonstrated in endometrial stromal cells only after decidualization. The aim of t...

The interleukin-11 (IL-11) receptor alpha has an important function in decidualization of mouse endometrial stroma but the function of IL-11 and its receptor in the human endometrium remains unknown. The mRNA for IL-11 and its receptor alpha in human endometrial tissue samples were analysed by semi-quantitative RT-PCR and RNase protection assays respectively. The proteins were detected in froze...

Endometrial cancer is the most common malignancy of the lower female reproductive tract. The tumor suppressor FOXO1 is downregulated in endometrial cancer compared with normal endometrium but the underlying mechanisms are not well understood. Using microRNA (miR) target prediction algorithms, we identified several miRs that potentially bind the 3'-untranslated region of FOXO1 transcripts. Expre...

Context Heavy menstrual bleeding (HMB) is common and incapacitating. Aberrant menstrual endometrial repair may result in HMB. The transforming growth factor (TGF)-β superfamily contributes to tissue repair, but its role in HMB is unknown. Objective We hypothesized that TGF-β1 is important for endometrial repair, and women with HMB have aberrant TGF-β1 activity at menses. Participants/Settin...
