The pathogenesis of preeclampsia is unclear but is thought to be related to shallow trophoblast invasion. An invasive phenotype is acquired by trophoblasts through the process of epithelial-mesenchymal transition (EMT). We proposed that EMT in trophoblasts is deregulated in preeclampsia. The homeobox gene DLX4 plays an important role in epithelial-...
... 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]. ...
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...

... With respect to other cancers, lithium has been found to be lethal to neuroblastoma cells but not to normal nerve cells (11). A similar effect was found in ovarian cancer cells (12), although a subsequent similar study on ovarian cancer cells suggests only a more modest benefit (13). It is not clear from our reading of the two ovarian cancer papers why the results are significantly different from each other. ...
... In vEDS cells, an ER perturbation was suggested by the abnormal ER distribution of the protein disulfide isomerase enzyme and by reduced expression of FKBP22, an ER resident peptidyl-prolyl cis-trans-ER isomerase involved in the folding of COLLIII triple helix [108,139,140]. Since the perturbed ER redox state may influence the down-regulation of Bcl-2 and the activation of the caspase-dependent apoptosis [141], and FKBP22 can have an anti-apoptotic role acting on the expression of Bcl-2 and caspases [142], this aspect merits further studies in vEDS fibroblasts. ...

To elucidate the mechanisms of nuclear estrogen receptor (ER)-mediated and G protein-coupled receptor 30 (GPR30)-mediated signaling in the regulation of proliferation in ER-positive and ER-negative endometrial cancer cells, two human endometrial carcinoma cell lines, Ishikawa (ER-positive) and KLE (ER-negative), were used. PCR and Western blot anal...


Shortly after his marriage to Feng Heng, Huang Yaoshi met Wang Chongyang's junior, Zhou Botong. He learnt from Zhou Botong that Wang Chongyang had died and that Zhou had inherited the Nine Yin Manual. He wanted the book for himself so he tricked Zhou Botong into allowing his wife to read it. Zhou Botong agreed and let her read the second volume of the manual. Feng Heng had eidetic memory so she memorised the book easily. She lied to Zhou Botong that the manual was fake and that it was actually a copy of a book of childish rites she had memorised by heart. She recited the first few verses of the manual verbatim to Zhou Botong, who mistakenly believed her and destroyed the book in anger. After Zhou Botong left, Feng Heng wrote a copy of the manual from memory for her husband.
Our previous studies have showed that Gankyrin expression is correlated with a malignant phenotype in endometrial carcinoma. Here, we investigated the possible role of Gankyrin in cervical disease. The increasing protein level of Gankyrin was observed in high-grade cervical intraepithelial neoplasia and carcinoma compared with benign cervical tissu...
Huang Yaoshi is married to Feng Heng and has six apprentices. He has scores of servants on his island, who are deaf and mute. Rumours in the jianghu say that he intentionally disabled them, but in fact, they were already mute and deaf before they became his servants. He recruited them as his servants to relieve them from the social stigma of their impairments so that they can enjoy a better life on his island. However, he does not wish to promote an image of himself as a kind and compassionate person so he spread those negative rumours about himself. Only his family and apprentices know the truth.
Persistent unopposed estrogen stimulation is a central oncogenic mechanism driving the formation of type I endometrial cancer (EC). Recent epidemiologic and clinical studies of EC have also revealed a role for insulin resistance, clinically manifested by chronic inflammation. However, the role of inflammation in estrogen-driven EC is not well chara...
There is evidence to suggest that follicle-stimulating hormone (FSH) can facilitate the neovascularization of ovarian cancers by increasing vascular endothelial growth factor (VEGF) expression in cancer cells, although the underlying molecular mechanism of this process is not well known. Therefore, we investigated the effect of FSH on VEGF expressi...
... This process takes place at the beginning of vascular development and during post-natal life (11,22). Myeloid cells and EPCs are recruited by pro-angiogenic or pro-inflammatory factors to the tumor vascular bed, where they differentiate into ECs and give place to neovasculature (23)(24)(25). Vasculogenesis has a modest impact on tumor vascularization when the angiogenesis pathway is active, however, it is recognized as an important rescue process when this pathway is blocked (10,26). For instance, when angiogenesis is inhibited after anti-angiogenic treatment or radiotherapy, myeloid cells, and EPCs are recruited by the stroma-derived factor 1 (SDF-1) in response to an increased level of hypoxia-inducible factor 1α (HIF-1α) (10,26). ...
Objective: To investigate the chemosensitivity of ovarian cancer SK-OV-3ip1 multicellular aggregates (MCA) to cisplatin and taxol and to explore the possible mechanisms. Methods: Liquid overlay system was employed to obtain MCA. We detected the resistance using trypan blue exclusion testing, clonogenic assay, cell cycle profiles and apoptosis with...
Neovascularization is essential for tumor growth and metastasis. An adequate vasculature feeds tumor growth and enhances the potential of metastasis. For many years, tumor vessels were thought to be lined exclusively by endothelial cells (ECs). However, therapeutic benefits from the promising antiangiogenic strategy targeting genetically stable ECs...
To identify an effective auxiliary therapy for epithelial ovarian cancer. Progesterone acetate given at 250 mg intramuscularly twice a week for 1 month followed by increased administration to 500 mg intramuscularly every two weeks for 3 years was used in combination with platinum based chemotherapy to treat patients with epithelial ovarian cancer a...

On February 13, 2004, Yuntai Mountain as the fifth in the world, the third in the country China, was named the world's first World Geopark by UNESCO and caused attention at home and abroad. Meanwhile, Yuntaishan is also a national scenic spot, National Civilized Scenic Area, the first national AAAAA-level scenic spot, national natural heritage, national forest parks, national macaque nature reserve. Yuntain Mountain also has Asia's highest head drop waterfall.
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...
Genistein, the most abundant phytoestrogen in soybeans, may bind to estrogen receptors and perform anticancer activities. Choriocarcinoma is a malignant, trophoblastic and aggressive cancer of the placenta. Few studies are currently available concerning the effects of genistein on choriocarcinoma. In the present study, we investigated the effect of...

NANOG is a key transcription factor that is overexpressed and plays an important role in various cancers. Its overexpression is associated with highly tumorigenic, drug-resistant, and poor prognosis. However, the underlying mechanism of action of NANOG in ovarian cancer remains unclear. Epithelial-mesenchymal transition (EMT), which is a critical p...
