Rac1 promotes diethylnitrosamine (DEN)-induced formation of liver tumors

Metastatic rate of liver tumors induced by diethylnitrosamine in mice.

The effect of celecoxib on the development of diethylnitrosamine-induced liver tumors in rats.

BACKGROUND/AIMS Hepatocellular carcinoma is one of the most commonly diagnosed malignant tumors in the world, and it typically has a poor prognosis. Extensive studies have examined the effects of non-steroidal anti-inflammatory drugs selective to COX-2 on the chemoprevention of various tumors. The objective of this study is to observe the effect of celecoxib on the development of liver tumors i...

Expression of retroviral sequences and oncogenes in rat liver tumors induced by diethylnitrosamine.

The expression of three cellular oncogenes (c-myc, c-Ha-ras, and c-delta-raf), the epidermal growth factor receptor gene, and two endogenous retrovirus-like sequences [rat leukemia virus (RaLV) and 30S] was examined in control rat livers and in 16 liver tumors. The tumors were induced in Sprague-Dawley male and female rats by a single i.p. injection of diethylnitrosamine at 1 or 2 days after bi...

DJ-1 promotes development of DEN-induced hepatocellular carcinoma and proliferation of liver cancer cells

Chronic liver inflammation and injuries play a critical role in development of hepatocellular carcinoma (HCC). Parkinson disease (autosomal recessive, early onset) 7, encoding PARK7 protein (also called DJ-1), plays important roles in many carcinogenesis processes and is essential in modulating inflammation. However, whether DJ-1 is involved in HCC development remains largely unknown. To determ...

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...
