Exposure of female hepatitis B virus transgenic mice of lineage 50-4, which display liver injury secondary to overexpression of the gene for the large envelope polypeptide of hepatitis B virus, to the hepatocarcinogens aflatoxin and diethylnitrosamine produced more rapid and extensive evidence of nodule formation and oval cell proliferation, as well as the development of adenomas and primary he...

conditions was the compound found to be mutagenic. Mutants were induced in a gentically marked 2-component heterokaryon and recovered as purple colonies among the white, nonmutant background colonies. In this system, purple colonies result from two types of genetic damage in the adenine-3 region: point mutations at ad-3A and ad-3B loci and multilocus deletions covering one or both loci simultan...

Dysfunctional autophagy is associated with tumorigenesis; however, the relationship between the two processes remains unclear. In the present study, we showed that MAP1S levels immediately become elevated in response to diethylnitrosamine-induced or genome instability-driven metabolic stress in a murine model of hepatocarcinoma. Upregulation of MAP1S enhanced autophagy to remove aggresomes and ...

Purpose: To explore the effects of Carthamus tinctorius L. extract (CTLE) on diethylnitrosamine (DEN)induced liver cirrhosis in rats. Methods: CTLE was obtained by extracting the dried Carthamus tinctorius L. in water. Liver cirrhosis was induced by injecting the rats with DEN once a week for 8 weeks. Following this treatment, clinical biochemical assessments, as well as oxidative stress test a...

Experimental chemical hepatocellular carcinomas that were induced in male F344 rats using three different regimens of limited exposure to the carcinogens 2-acetylaminofluorene or diethylnitrosamine were characterized by very low (as compared to peritumorous or normal tissues) binding of epidermal growth factor and decreased autophosphorylation of the epidermal growth factor receptors. Similar c...

A binary mixture of (S)-(-)-1-phenyl-ethanamine and hexa-noic acid was allowed to react to form the title salt, C8H12N(+)·C6H11O2(-). This crystal contains a 1:1 stoichiometric mixture of the acid- and amine-derived species and displays a chiral structure with N-H⋯O hydrogen-bonded chains propagating along the c-axis direction.
