The viral oncoprotein HBx of Hepatitis B virus promotes the growth of hepatocellular carcinoma through cooperating with the cellular oncoprotein RMP.

The smallest gene HBx of Hepatitis B virus (HBV) is recognized as an important viral oncogene (V-oncogene) in the hepatocarcinogenesis. Our previous work demonstrated that RMP is a cellular oncogene (C-oncogene) required for the proliferation of hepatocellular carcinoma (HCC) cells. Here we presented the collaboration between V-oncogene HBx and C-oncogene RMP in the development of HCC.

Precautions in caudate lobe resection: report of 11 cases.

Aim: To find the precautions against the safety in caudate lobe resection.

Methods: The clinical data obtained from 11 cases of primary liver cancer in caudate lobe who received hepatectomy successfully were retrospectively analyzed. Four safe procedures were used in resection of primary liver cancer in caudate lobe: (1) selection of appropriate skin incision to obtain excellent exposure of operative field; (2) adequate mobilization of the liver to allow the liver to be displaced upwards to the left or to the right; (3) preparatory placement of tapes for total hepatic vascular exclusion, so that this procedure could be used to control the fatal bleeding of the liver when necessary; (4) selection of the ideal route for hepatectomy based on the condition of the tumor and the combined removal of multiple lobes if necessary.
