Objective To study the expression of intermediate? conductance? Ca2+-activatedK+ (KCa3.1) channelsin Endometrial cancer tissues and their role in regulating cell cycle of endometrial cancer cells.Methods Real?time PCR and Western blotting analysis were used to examine the expression of KCa3.1 channels in 25 normal endometrial specimens,26 atypical...
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-...
Snail, a key inducer of epithelial-mesenchymal transition (EMT), plays an important role in cancer metastasis. To better understand the role of Snail in the metastasis of ovarian carcinoma, expression of Snail was knocked down by antisense-Snail in the highly metastatic ovarian cancer cell line HO8910PM. Gene array analysis revealed that blocking S...

Although glycogen synthase kinase-3 (GSK-3) might act as a tumor suppressor since its inhibition is expected to mimic the activation of Wnt-signaling pathway, GSK-3beta may contribute to NF-kappaB activation in cancer cells leading to increased cancer cell proliferation and survival. Here we report that GSK-3beta activity was involved in the prolif...
The Joint Institute has tuition-waived student exchange agreements with a several leading universities as well as various programs with the university of Michigan. If your university is a member of the Global E³ Network or you believe that your institution has an exchange agreement with Shanghai Jiao Tong University (SJTU), please contact your international programs office for information on how to apply.
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...

To compare the therapeutic and toxic profile of topotecan given intraperitoneally with intravenously in human ovarian cancer xenografted into athymic nude mice. Eighty female Balb-c/nu-nu mice were randomized assigned into eight groups (n=10). Xenografts resulted from intramesentery injection of cultured human ovarian cancer cells SKOV3 in athymic...
... 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. ...
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...
Ovarian carcinoma is leading cause of death in gynecologic malignancies. The survival rate cannot be improved after routine surgery, chemotherapy, and radiotherapy. Therefore biotherapy becomes the fourth treatment pattern for ovarian carcinoma. Adequate experimental models for the development of biologic therapeutic strategies are needed. Our purp...

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.
