Liver transplantation for diethylnitrosamine-induced hepatocellular carcinoma in rats.
H UMAN hepatocellular carcinoma (HCC) is a highly malignant tumor with a natural history of a few months from the time of diagnosis. Curative resection offers the best chance of survival. l However, surgical resectability rates rarely exceed 30% to 40% because of extensiveness of the tumors or because coexisting liver disease precludes attempted partial hepatectomy.2 Consequently, total liver r...
متن کاملHistochemical profile of mouse hepatocellular adenomas and carcinomas induced by a single dose of diethylnitrosamine.
In continuation of earlier studies on murine neoplastic liver lesions, we characterized by histochemical methods the phenotype of hepatocellular adenomas and carcinomas induced by single injections of diethylnitrosamine (1.25, 2.5, or 5.0 micrograms/g of body weight) in 15-day-old C57BL/6 x male C3H F1 mice. The hepatocellular adenomas were composed predominantly of basophilic cells but stored ...
متن کاملDietary restriction protects against diethylnitrosamine-induced hepatocellular tumorigenesis by restoring the disturbed gene expression profile
Hepatocellular carcinoma (HCC) is one of the most lethal and prevalent malignancies, worse still, there are very limited therapeutic measures with poor clinical outcomes. Dietary restriction (DR) has been known to inhibit spontaneous and induced tumors in several species, but the mechanisms are little known. In the current study, by using a diethylnitrosamine (DEN)-induced HCC mice model, we fo...
متن کاملCytokeratin polypeptide expression during the histogenesis of guinea pig submandibular salivary gland.
The present study was directed towards the characterization of cell-specific histogenetic markers for the various epithelial elements of the adult and the developing guinea pig submandibular salivary gland. We have employed immunofluorescent labelling using three cytokeratin monoclonal antibodies, for which the polypeptide specificities towards guinea pig cytokeratins were determined. All the e...
متن کاملCytokeratin 20-positive hepatocellular carcinoma
The differential diagnosis between hepatocellular carcinoma (HCC), cholangiocarcinoma (CC) and metastatic colorectal adenocarcinoma (MCA) may be difficult when only based on morphology. For this purpose immunohistochemical analyses are often required, utilizing antibodies directed against CK8-18, Hep-Par1, glypican 3, CK7, CK19, CK20. Here we report a case of a 65-year-old man who presented wit...
