Amplification of chromosome arm 3q is the most consistent aberration in cervical cancer, and is implicated in the progression of dysplastic uterine cervical cells into invasive cancer. The present study employed the 'positional candidate gene' strategy to determine the contribution of PIK3CA, which is located in 3q26.3, in cervical tumorigenesis. PIK3CA is(More)
The tumor-suppressor gene p53 acts as "the guardian of the genome", sensing DNA damage and initiating protective responses. To examine the hypothesis that p53 abnormality leads to increased genomic alterations in primary tumor cells, our study utilized 51 primary tumors of cervical carcinoma and 10 microsatellite markers. These markers were mapped to the(More)
Shedding of syncytiotrophoblast microparticles (MPs) from placenta to maternal blood occurs in normal pregnancy and is enhanced during preeclampsia (PE). The syncytiotrophoblast synthesizes plasminogen activator inhibitors (PAIs) which regulate fibrinolysis, as well as soluble forms of the fms-like tyrosine kinase (sFlt-1) and endoglin, which exert(More)
The plasminogen activator inhibitors (PAIs) play critical roles in regulating hemostatic and invasive functions of trophoblasts through suppression of plasmin-dependent fibrinolysis and extracellular matrix degradation. The expression of PAI-1 is increased under hypoxic conditions, although the mechanism remains incompletely understood. In the current study(More)
In order to outline the pathways of gastrointestinal malignancies metastasizing to the ovaries, we reviewed 103 cases of metastatic ovarian tumors, and also performed para-aortic lymph node sampling on 11 patients at operation for metastatic ovarian tumors. Of the 103 patients, 74% (26/35) with gastric cancer and 67% (45/67) with colorectal cancer had lymph(More)
BACKGROUND Hepatocellular carcinoma (HCC) is highly malignant and metastatic. Currently, there is no effective chemotherapy for patients with advanced HCC leading to an urgent need to seek for novel therapeutic options. We aimed to investigate the effect of a garlic derivative, S-allylcysteine (SAC), on the proliferation and metastasis of HCC. (More)
BACKGROUND Surgical procedures such as liver resection and liver transplantation are the first-line treatments for hepatocellular carcinoma (HCC) patients. However, the high incidence of tumor recurrence and metastasis after liver surgery remains a major problem. Recent studies have shown that hepatic ischemia-reperfusion (I/R) injury and endothelial(More)
Human hepatocellular carcinoma (HCC) is the fifth most common cancer worldwide with a poor prognosis of limited survival. The role of regulatory B cell (Breg), a new important B cell subset, in HCC progression remains unclear. We firstly found that the percentage of B cells at tumor margin was significantly higher than that in tumor and non-tumor regions.(More)
The surround suppression of the receptive field is important for basic visual information processing, such as orientation specificity. To date, the effects of aging on the strength of surround suppression are not clear. To address this issue, we carried out extracellular single-unit studies of the receptive field properties of cells in the primary visual(More)
OBJECTIVE We aim to investigate the role of aldose reductase (AR) in hepatic ischemia-reperfusion injury (IRI) of normal and fatty livers and to explore the underlying mechanisms. BACKGROUND Hepatic IRI is a typical inflammatory response during liver surgery. It contributes to liver graft failure or nonfunction after transplantation. Increasing evidence(More)
