BACKGROUND The role of Epstein-Barr virus (EBV) infection in gastric carcinogenesis remains largely unknown. The authors studied the effects of zinc finger E-box binding factor 1 (ZEB1) on latent-lytic switch of EBV infection in gastric cancer and explored the importance of EBV in gastric carcinogenesis. METHODS Loss or gain of ZEB1 function was obtained(More)
MicroRNAs (miRNAs) have been reported to play an important role in tumorigenesis. In this study, the role of miR-15a and miR-16-1 in gastric adenocarcinoma (GAC) was investigated. The expression of miR-15a and miR-16-1 in cell lines and primary tumors was examined by miRNA qRT-PCR. Proliferative assays, colony formation, cell invasion and migration, flow(More)
Nonalcoholic steatohepatitis with fibrosis is a more severe form of nonalcoholic fatty liver disease, one of the most common liver diseases. We have previously shown that peroxisome proliferator-activated receptors gamma (PPARgamma) ligand, rosiglitazone, prevented the development of the methionine choline deficient (MCD) diet-induced fibrosing(More)
UNLABELLED Although peroxisome proliferator-activated receptor gamma (PPARgamma) agonist have been shown to inhibit hepatocellular carcinoma (HCC) development, the role of PPARgamma in hepatocarcinogenesis remains unclear. We investigated the therapeutic efficacy of PPARgamma against HCC. PPARgamma-deficient (PPARgamma(+/-)) and wild-type (PPARgamma(+/+))(More)
BACKGROUND Aberrant methylation of tumor-related genes has been reported in Epstein-Barr virus (EBV)-associated gastric cancers. This study sought to profile EBV-driven hypermethylation in EBV-infected cells. METHODS The EBV-positive AGS gastric cancer cell line (AGS-EBV) and EBV-negative AGS cells were used in this study. DNA methyltransferase-3b(More)
A gene encoding a homologue of phospholipase A(2) was identified from the Clonorchis sinensis adult cDNA plasmid library. The deduced amino acid sequence including a signal peptide that has 28-46% identity with secretory phospholipase A(2), group III (group III sPLA(2)) of other species. It also has typical features of group III sPLA(2)s including 10(More)
Cysteine proteases (CPs) were associated with the pathogenicity and excystment of Clonorchis sinensis. Most of them were potential antigens for the immunodiagnosis of clonorchiasis. More researches on CPs will let us know more about their functions, and further employ them for the development of more efficient diagnostic reagent and prevention strategies.(More)
Clonorchiasis is a common zoonosis in southern and northeastern parts of China, especially in Guangdong, Guangxi and Jilin province. Anti-Clonorchis sinensis antibody detection by enzyme-linked immunosorbent assay (ELISA) has been used for epidemiological surveys of clonorchiasis for its convenience and celerity, but it is still a meaningful work to screen(More)
UNLABELLED Dysregulated microRNA (miRNA) expression was profiled through a miRNA array comparison between human colorectal cancer tumors and their adjacent normal tissues. Specifically, using laser capture micro-dissection, miR-133a was shown to be significantly downregulated in primary colorectal cancer specimens compared with matched adjacent normal(More)
Yin Yang 1 (YY1) is a transcription factor that regulates diverse biological processes and increasing recognized to have important roles in carcinogenesis. The function and clinical significance of YY1 in gastric adenocarcinoma (GAC) have not been elucidated. In this study, the functional role of YY1 in gastric cancer was investigated by MTT proliferation(More)
