Endometrial interleukin-6 (IL-6) mRNA has been reported to be suppressed in the mid-secretory phase in patients with recurrent early spontaneous abortions. This prompted our study concerning the regulation of endometrial IL-6 in cell culture models of endometrial epithelial and stromal cells. Steroid-dependent secretion of IL-6 was analysed by 17beta-estradiol (10(-8) mol/l) or progesterone (10...

Endometrial stromal tumors are rare, and endometrial stromal nodule is the least common. In the region of Middle Jutland, Denmark, only two cases are reported since 1995. The nodules are benign; nevertheless, hysterectomy is the treatment of choice. Tumor margins are required for diagnosis and essential to differentiate it from an invasive stromal sarcoma whose prognosis is very different. We r...

BACKGROUND Adiponectin is one of the most important adipokines secreted from fatty tissue that has a direct inhibitory effect on the development of cancer cells. Adiponectin plays an important role in human reproduction system and fertility of women. Adiponectin concentration decreases in women with endometriosis and endometrial cancer. The aim of the present study was to investigate the effect...

Uterine and extrauterine tumors composed of cells featuring endometrial stromal cells often show ovarian sex cord-like structures and smooth muscle differentiation. A few cases of endometrial stromal tumors showing rhabdoid differentiation have been reported. The present case is a 20-year-old woman with endometrial stromal sarcoma that had sex cord-like structures, smooth muscle components and ...

We applied in the previous study miRNA microarray screening analysis to identify several differentially expressed miRNAs, including miR-183 in normal, eutopic, and ectopic endometrium. Knockdown of miR-183 expression induced the invasiveness and inhibition of apoptosis in endometrial stromal cells. The current study aims to identify the miR-183 targets with relevance to cell functions in endome...

UNLABELLED OBJECTIVE[S]: Activin A and inhibin A are growth factors expressed by human endometrium involved in the control of endometrial functions. In the present study we investigated the effects of activin A and inhibin A in modulating the tumor necrosis factor (TNF)-alpha/intercellular adhesion molecule (ICAM)-1 system in cultured human endometrial stromal cells. STUDY DESIGN Endometrial ...

s:3115:"Background: During reproductive life, the human endometrium undergoes around 500 cycles of growth, breakdown and regeneration. This outstanding regenerative capability is the basis for cyclic endometrial preparation and its dysfunction is involved in pathological disorders. Endometrial regeneration is mediated by the existence of a specialized endometrial stem cell (SC) population recen...

OBJECTIVE To investigate the role of interleukin-1beta (IL-1beta) in regulating GnRH mRNA expression in cultured human endometrial stromal cells using a modified semiquantitative competitive reverse transcription and polymerase chain reaction (PCR). DESIGN A controlled study. SETTING Clinical and academic research setting in a university medical center. PATIENT(S) Women undergoing hystere...

The contribution of the stromal microenvironment to the progression of endometrial cancer has not been well explored. We have conditionally expressed a mutant allele of adenomatous polyposis coli (APC(cKO)) in murine uterine stroma cells to study its effect on uterine development and function. In addition to metrorrhagia, the mice develop complex atypical endometrial gland hyperplasia that prog...

The hallmark of the menstrual cycle is extensive steroid-dependent tissue turnover. Estrogen mediates endometrial cell growth and structural remodeling, whereas progesterone suppresses estrogen-dependent proliferation and promotes cellular differentiation. In nonfertile cycles, tissue degradation and menstruation occur as a consequence of steroidal deprivation as the ovarian corpus luteum fails...
