Lack of inhibitory effects of the Ju-myo protein on development of glutathione S-transferase placental form-positive foci in the male F344 rat liver.

چکیده
The effects of the 77 kDa Ju-myo protein, isolated from Drosophila melanogaster, on the development of glutathione S-transferase placental form (GST-P) positive foci in the male F344 rat liver were evaluated using a medium-term bioassay system. No modifying potential was evident in terms of the numbers or areas of GST-P positive foci. Ju-myo protein did not exert any influence on cell proliferation, as reflected by ornithine decarboxylase (ODC) or spermidine/spermine N1-acetyltransferase (SAT) activity and BrdU labeling. These results demonstrated that Ju-myo protein is unlikely to have inhibitory or promoting effects on rat liver carcinogenesis.

The enhancing effect of ethanol on the development of glutatione S-transferase placental form-positive foci induced by diethylnitrosamine in F344 rat.
The effects of ethyl alcohol and pig serum administration on the development of preneoplastic hepatic enzyme-altered foci were examined in an in vivo mid-term assay system. Rats were initially given a single dose (200 mg/Kg) intraperitoneal injection of diethylnitrosamine (DEN). Two weeks later, treatment was started with 10% ethanol + 10% sucrose solution, 10% sucrose solution, or tap water as...

Ten organosulfur compounds from garlic and onions were studied for their modifying effects on diethylnitrosamine-induced neoplasia of liver in male F344 rats using the medium-term bioassay system of Ito based on the two-step model of hepatocarcinogenesis. Carcinogenic potential was scored by comparing the number and area per cm2 of induced glutathione S-transferase placental form-positive foci ...

The distributions of a gap junctional protein, connexin 32 (cx 32), and proliferating cell nuclear antigen (PCNA) were examined immunohistochemically in glutathione S-transferase placental form (GST-P)-negative foci, induced in rat liver by initiation with diethylnitrosamine (DEN, 200 mg/kg) followed by promotion with clofibrate (1% in diet) in an in vivo medium-term assay system for hepatocarc...
متن کاملPresence of a threshold for promoting effects of phenobarbital on diethylnitrosamine-induced hepatic foci in the rat.
The dose dependence of the hepatopromoting effects of phenobarbital (PB) was investigated in a rat liver medium-term bioassay (Ito test) to elucidate a practical threshold level. F344 rats were given a single i.p. injection of diethylnitrosamine (200 mg/kg body wt) and subjected to two-thirds partial hepatectomy at week 3. Commencing 2 weeks from the start, PB at doses of 0, 1, 2, 4, 7.5, 15 or...
متن کاملSpecific differences in gene expression profile revealed by cDNA microarray analysis of glutathione S-transferase placental form (GST-P) immunohistochemically positive rat liver foci and surrounding tissue.
Glutathione S-transferase placental form (GST-P), one of the glutathione S-transferases family of detoxification enzymes, is a very useful marker of rat liver pre-neoplastic lesions. We here investigated the gene expression profile in GST-P positive foci as compared with surrounding GST-P negative areas in the same liver of rats treated with diethylnitrosamine and then 2-acetylaminofluorene com...
