NANOG is a major transcription factor essential to the stem cell self-renewal and is associated with tumor malignancy, but the NANOG signaling in cancer metastasis is still elusive. In this study, we determined the expression of NANOG in hepatocellular carcinoma (HCC) and investigated its underlying mechanism in the metastasis of HCC. The expression levels(More)
The study aims to develop novel clinical immunohistochemical biomarkers for distinguishing small hepatocellular carcinoma (sHCC) from dysplastic nodules (DN). iTRAQ-2DLC-ESI-MS/MS technique was used to screen immunohistochemical biomarkers between precancerous lesions (liver cirrhosis and DN) and sHCC. A total of 1951 proteins were quantified, including 52(More)
Dysregulation of androgen-binding protein (ABP) is associated with a number of endocrine and andrology diseases. However, the ABP metabolism in Sertoli cells is largely unknown. We report that autophagy degrades ABP in rat Sertoli cells, and the autophagic clearance of ABP is regulated by testosterone, which prolongs the ABP biological half-life by(More)
AIM To find out potential serum hepatocellular carcinoma (HCC)-associated proteins with low molecular weight and low abundance by SELDI-based serum protein spectra analysis, that will have much application in the diagnosis or differentiated diagnosis of HCC, as well as giving a better understanding of the mechanism of hepato-carcinogenesis. METHODS Total(More)
OBJECTIVE To explore the biological function and possible underlying mechanism of aldo-keto reductase family 1 member B10 (AKR1B10) gene during hepatocarcinogenesis. METHODS A pair of chemically synthesized small interfering RNA (siRNA) targeting on AKR1B10 was transfected into liver cancer cell line MHCC97H by LipofectamineTM 2000. After confirming the(More)
OBJECTIVE To screen the differentially expressed proteins especially at the precancerous stage of diethylnitrosamine (DEN) induced hepatocarcinogenesis by comparative proteome research. METHODS Rats were divided into normal and DEN groups and sacrificed periodically. The liver samples were stained with gamma-glutamyl transpeptidase (GGT) and HE to(More)
We describe a liveborn infant with uniparental disomy (UPD) with trisomy 15 mosaicism. Third trimester amniocentesis yielded a 46,XX/47,XX,+15 karyotype. Symmetrical growth retardation, distinct craniofacies, congenital heart disease, severe hypotonia and minor skeletal anomalies were noted. The infant died at 6 weeks of life. Peripheral lymphocyte(More)
OBJECTIVE To analyze the expression of genes in the Slit/Robo signaling pathway, and the methylation status of their promoters in hepatocellular carcinoma (HCC) cell lines. METHODS Genomic DNA and total RNA were isolated from 9 HCC cell lines of different metastatic ability (Hep3B, HepG2, PLC/PRF/5, SMMC-7721, BEL-7402, MHCC97-H, MHCC97-L, LM3, LM6) and a(More)
OBJECTIVE To test expression level and glycosylation level of OPN in HCC cell lines with different metastatic potential and HCC tissues, and investigate the correlation between the glycosylation change and the liver cancer transporting as well as its significance. METHODS The level of OPN expression in liver cancer tissue(6 cases of non-metastasis and 7(More)
OBJECTIVE To profile the methylation alterations of CpG islands in hetpatocellular carcinoma cell lines. METHODS A global analysis of DNA methylation using the Human CpG-island 12K Array (HCGI12K) from Canada University Health Network was performed on nine human hepatocellular carcinoma (HCC) cell lines (Hep3B, HepG2, PLC/RPF/5/RPF/5, SMMC-7721, BEL-7402,(More)
