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)
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)
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)
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)
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)
Some biosamples obtained from biobanks may go through thawing before processing. We aim to evaluate the effects of thawing at room temperature for different time periods on gene expression analysis. A time course study with four time points was conducted to investigate the expression profiling on 10 thawed normal mice renal tissue samples through Affymetrix(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)
