Progestin is an effective endocrine treatment for patients with atypical hyperplasia or with endometrial carcinoma that is estrogen receptor (ER) positive and progesterone receptor (PR) positive. However, long-term progestin treatment may lead to resistance. We have studied the progestin resistance phenotype that frequently develops in endometrial...
Previously, we demonstrated that follicle stimulating hormone (FSH) enhanced VEGF expression and facilitated ovarian cancer angiogenesis via the PI3K/AKT signaling pathway. In this study, we further investigated the involvement of microRNA-27a: ZBTB10‑specificity protein pathway in the mechanism of FSH-induced VEGF, Cox2 and survivin expression. Tr...
The construction of the campus never came to an end in the past century. Existing buildings: the Middle College building (built in 1898), the original library (built in 1919), the gymnasium (built in 1925), the administrative building (built in 1933), the Xinjian building (built in 1953), the new Upper College building (built in 1955), the second teaching building (built in 1960), Bao Zhaolong library (built in 1985) and Haoran high-tech building (built in 1996) were constructed one after another.
Chemoresistance is the major obstacle to cure endometrial cancer, whereas metformin has demonstrated sensitization to chemotherapy in endometrial cancer. A novel finding states that isocitrate dehydrogenase 1 (IDH1) involves in cancer chemoresistance. Recent studies have revealed that epigenetic modifications facilitate chemoresistance. However, wh...
High levels of gonadotropin are a risk factor for ovarian cancer development. Aberrant gonadotropin levels benefit tumor angiogenesis, but the detailed mechanism is not clear. Therefore, the aim of this study was to investigate the molecular mechanism of high levels of luteinizing hormone (LH) on the promotion of tumor angiogenesis and to outline a...
... However, no clear morphologic changes were found between control cells and Snail-knockdown cells. 16 Although the Ecadherin expression could not be detected in these cells at protein lever (Fig. 1a), but there is significant upregulation of E-cadherin mRNA after knockdown expression of Snail (Fig. 1b), indicating that Snail is required to suppress the expression of E-cadherin in ovarian cancer. In addition, expression of fibronectin, one of the mesenchymal markers, was greatly downregulated in the stable antisense-Snail-transfected cells when compared with the parental cells (Fig. 1b). ...
To study the expression of intermediate-conductance-Ca(2+)-activated K(+) (IKCa1) channels in endometrial cancer and its role in regulating proliferation of endometrial cancer cells. Western blot and RT-PCR were used to examine the expression of IKCa1 channels in 13 normal endometrial specimens and 25 endometrial cancer specimens; and RNA interfere...
We previously showed that the expressing level of FSH receptor (FSHR) increased from ovarian epithelial inclusions (OEIs) to benign ovarian epithelial tumors (OETs) and to borderline OETs, whereas FSHR levels decreased with an increase in carcinoma grade. The aim of this study was to investigate the role of FSHR in OET development. MCV152 cells wit...
Objective To assess the effect of 17β-estradiol(E2) on cell proliferation, cell invasiveness and its regulation of MTA3, Snail and matrix metalloproteinase 2 (MMP-2) expression in the ovarian clear cell adenocarcinoma cell line ES2, and to further investigate the mechanism involved. Methods We first investigated expression of ERα, ERβ, PR and E-cad...
To explore possibility of vasculogenic mimicry induced by hypoxia and the inhibitive effect by sirolimus in epithelial ovarian carcinoma in vitro. Based on three-dimensional cell culture system developed by Matrigel, ovarian cell lines SKOV3 and ES2 were induced under conditions of hypoxia, hypoxia added with sirolimus and no-hypoxia, respectively....
To express tumor necrosis factor related apoptosis inducing ligand (TRAIL) protein using endothelial progenitor cell (EPC) and observe antitumor activity of secreted TRAIL in cell culture supernatant. EPC were isolated by immunomagnetic sorting. Human TRAIL plasmid was transfected into EPC by lipofectamine 2000. The cell culture supernatant was har...
... Interestingly, estradiol may play a dual role in modulating NRF2 activity. On the one hand, its metabolites activate NRF2 via the generation of reactive oxygen species (ROS) (independent of the ER) [29]. While recent studies demonstrated that estradiol leads to an activation of NRF2 in a wide range of cell types [30,31], the estradiol effect was only noted on protein and not on mRNA levels, suggesting that the main effect of estradiol is based on NRF2 protein stabilization [32]. ...
