In view of the controversies surrounding the glutathione S-transferases (GST) M1/T1-endometriosis association, a meta-analysis of the GSTM1/GSTT1 genetic association studies of endometriosis was performed. In this meta-analysis involving 14 GSTM1 studies with 1539 cases and 1805 controls and nine GSTT1 studies with 746 cases and 834 controls, respectively,(More)
OBJECTIVE To evaluate uterine contractility, oxytocin receptor (OTR) expression in myometrial smooth muscle cells (MSMCs) derived from uterine tissues from women with and without adenomyosis correlate OTR expression with uterine contractility and dysmenorrhea severity, and see whether trichostatin A (TSA) and andrographolide inhibit OTR expression. DESIGN(More)
BACKGROUND Decades of research suggest that endometriosis is a complex disorder, with varying severity, onset and progression. Many genes have been associated with endometriosis through a number of studies and now microarray analyses have added to the list of perturbed or differentially regulated genes. Thus, it is difficult to see 'the big picture' without(More)
The human endometrium undergoes cyclic morphological and functional changes during the menstrual cycle. These changes are driven mainly by steroid hormones and orchestrated by a myriad of genes - many of which have been identified recently as being epigenetically regulated. Epigenetic modifications, including DNA methylation and histone acetylations, are(More)
Smooth muscle metaplasia (SMM) and fibrotic tissues are frequently seen in endometriotic lesions, yet the mechanisms underlying their formation are poorly understood. In this study, we investigated the roles of activated platelets in driving epithelial-mesenchymal transition (EMT) and fibroblast-to-myofibroblast transdifferentiation (FMT) in endometriosis.(More)
BACKGROUND Growing evidence indicates that endometriosis is an epigenetic disease. Encouragingly, histone deacetylases (HDACs) and DNA methyltransferases have been shown to be promising targets by numerous in vitro studies. However, only a few studies have shown promising effects of HDAC inhibition in preclinical studies in endometriosis. While(More)
BACKGROUND Recently emerging evidence indicates that endometriotic lesions are wounds undergoing repeated tissue injury and repair (ReTIAR), and platelets induce epithelial-mesenchymal transition (EMT), fibroblast-to-myofibroblast transdifferentiation (FMT), leading ultimately to fibrosis. Due to the commonality of cyclic bleeding as in endometriosis,(More)
Maternal PI3K p110δ has been implicated in smaller litter sizes in mice, but its underlying mechanism remains unclear. The placenta is an indispensable chimeric organ that supports mammalian embryonic development. Using a mouse model of genetic inactivation of PI3K p110δ (p110δ(D910A/D910A)), we show that fetuses carried by p110δ(D910A/D910A) females were(More)
BACKGROUND AND OBJECTIVE Radical parametrectomy (RP), performed either abdominally (ARP) or laparoscopically (LRP), is a viable alternative to radiotherapy in treating invasive cervical cancer, vaginal apex cancer, and endometrial cancer that is more advanced than initially suspected after hysterectomy. We carried out a comparative study on intra- and(More)
