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...
Our previous study revealed that estrogen regulates nm23-H1 expression thus promoting cell migration-invasion via activating PIK3/Akt pathway. In this study, we explored the effect of hormone on hypoxia-inducible factor-1 (HIF-1alpha), a key factor in cancer invasion and metastasis, via activation of Akt signaling transduction pathway. We treated t...
Aberrant nuclear factor-erythroid 2 (NRF2) expression correlates with tumor development. We investigated NRF2 expression in ovarian epithelial carcinoma (OEC), aiming to identify associations with clinicopathological factors, hormones and induced reactive oxygen species (ROS). Immunohistochemical staining for NRF2 expression was performed on 10 ben...
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...
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...
To investigate natural spontaneous menopausal age, menstruation span and their relationship with menarche age and parity in Pudong district of Shanghai. From Jan 2007 to Jul 2008, 15 083 spontaneous menopause women undergoing cervical cancer screening were enrolled in this study. The questionnaire included menarche age, parity, spontaneous menopaus...
Recent studies have suggested that follicle-stimulating hormone (FSH) plays an important role in ovarian epithelial carcinogenesis. We demonstrated that FSH stimulates the proliferation and invasion of ovarian cancer cells, inhibits apoptosis, and facilitates neovascularisation. Our previous work has shown that transient receptor potential channel...
Purpose: It has previously been shown that follicle-stimulating hormone (FSH) and its receptor contribute to epithelial ovarian cancer (EOC) development. Epithelial-mesenchymal transition (EMT) is the early event of metastasis in cancer. Therefore, the aim of this study was to investigate the roles of FSH and the FSH receptor (FSHR) in EMT of EOC....

To study the expression of VEGF, KDR, MMP-1, and its transcription factor Ets-1 on the interstitial neovasculogenesis in human cervical carcinoma on molecular level, which may provide further theoretic bases on judgement of prognosis and explain interregularity between neovasculagenetic factors. VEGF, KDR, MMP-1, and Ets-1 were detected in 87 cervi...
To investigate the correlation of hypoxia-inducible factor (HIF)-1alpha and vascular endothelial growth factor (VEGF) or micro-vessel density (MVD). The ovarian cancer cell line SKOV3 was transplanted into nude mice to form xenogeneic tumor. Mice were treated with rapamycin 4 mg/kg, sulindac 100 mg/(kg.d) and saline 200 microl respectively. Express...
Up to 30% of failure rate in endometrial hyperplasia patients treated by progestin urges more detailed understanding of the mechanisms involved in progestin resistance. Survivin is a key regulator in the antiapoptotic network, and overexpression of survivin has been reported in endometrial hyperplasia and cancer. This study investigated the role of...
Estrogen and progestin are involved in ovarian carcinogenesis. Change in nm23-H1 expression and the PIK3/AKT pathway are involved in carcinogenesis, development, invasion and metastasis of ovarian cancers. Therefore, it is critical to understand the signaling pathways that regulate hormone-induced cell migration and invasion in ovarian cancer. We i...

Huang Yaoshi is very protective of his daughter and loves her with his life as she reminds him of his deceased wife. He imparts all his skills to her since she was a child and hoped to groom her to become his heir. When his daughter reaches adolescence, he decides to find a suitable husband for her. Ouyang Feng visits Peach Blossom Island with his nephew, Ouyang Ke, to propose a marriage between Ouyang Ke and Huang Rong. Huang Yaoshi favours Ouyang Ke and wants him to be his son-in-law. At the same time, Guo Jing also visits the island with his master, Hong Qigong. Hong Qigong nominates his apprentice to be Huang Yaoshi's son-in-law. Huang Yaoshi had met Guo Jing earlier at Guiyun Manor and wants to kill Guo to avenge Chen Xuanfeng.
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...
... 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]. ...
