Glucose transport across the plasma membrane, the first Gefitinib rate-limiting

step for glucose metabolism, is mediated by glucose transporter (GLUT) proteins. However, the expression of class 1 GLUT family in hepatocellular carcinoma (HCC), typical glycolytic tumor, is not fully elucidated yet. The aims of this study were to elucidate the pattern of GLUT expression in human HCC tissues, and to determine the effect of GLUT knockdown in vitro. Methods: Twenty-nine HCC tissues and matched non-tumorous liver tissues were obtained from surgical specimens of chronic hepatitis B patients from February 2010 to March 2013. Expressions of GLUT-1, GLUT-2,

GLUT-3 and GLUT-4 were quantified by qPCR and normalized to GAPDH. HBV pregenomic RNA of matched tissue samples were measured by real-time PCR. Clinical, radiologic and pathologic correlation was made with GLUT expression profiles. HepAD38 cells were treated with siRNA against GLUT-1, GLUT-2, GLUT-3 and GLUT-4 in order to assess the effect of GLUT knockdown on the cell proliferation and apoptosis. Results: At least one glucose transporter was over-expressed in HCC compared to non-neoplastic tissue in most patients (28/29). There were significant correlations between expression of GLUT-2, GLUT-3 and GLUT-4 (p <0.005). selleck compound Overexpression of GLUT-2, GLUT-3 and GLUT-4 was correlated with low tumor necrosis and increased fatty change. Expressions of GLUT-4 and that of

GLUT-2 were negatively correlated with level of serum PIVKA-II. Knockdown of GLUT-2, GLUT-3 and GLUT-4 with siRNA suppressed cell proliferation by 33.1%, 55.0% and 66.4%, respectively, and increased cell death / apoptosis. Conclusions: HBV-related HCC usually over-express one or more GLUTs. Knockdown of GLUT-2, GLUT-3, or GLUT-4 induces tumor cell death, suggesting their potential role as therapeutic targets.

“The association between hepatitis B virus (HBV) infection and myocardial injury has yet to be elucidated. We sought to investigate myocardial conditions in patients with chronic HBV infection. In 47 consecutive patients with chronic hepatitis B who had no overt heart disease, we performed electrocardiography, echocardiography, serum tests for myocardial injury, and thallium-201 myocardial scintigraphy. Myocardial perfusion defects were confirmed by the severity score (SS), which was calculated as the sum of thallium-201 perfusion defect scores.
