Abstract

Les virus de leucemie murine sont transcriptionnellement inactifs dans les cellules embryonnaires ou ils est soumis a plusieurs mecanismes de controle negatif. Cependant, dans de tres rares cas, ces virus peuvent etre integres a une unite de transcription cellulaire active et exprimes dans les cellules indifferenciees. Un transcrit hybride commencant au debut d'un gene cellulaire se poursuit dans l'ADN proviral et est episse en utilisant un site accepteur cryptique du virus. Un tel mecanisme pourrait aboutir a l'annexion par un retrovirus de sequences cellulaires en aval desquelles il est integre

Abstract

The inhibitor of DNA-methylation, 5-azacytidine (5- AzaC ) induced the appearance of cytokeratin-containing cells in several mesenchymal cell lines such as teratocarcinoma-derived fibroblasts, preadipocytes and myoblasts, NIH-3T3 fibroblasts and human embryonic fibroblasts. At optimal 5- AzaC concentrations the proportion of such cells was in the range of 10(-1) compared with 10(-6) -10(-4) in non-treated cultures. Dose-response curves indicated that the induction of cytokeratin was the result of an interaction of the drug with few targets. Stable, mature, keratinocyte cell lines, as well as lines of myoblasts and astrocytes, could be isolated from a teratocarcinoma-derived preadipocyte line, showing that 5- AzaC is able to provoke a wide range of complete phenotypic conversions. In these cell lines, the intermediate filaments corresponded to the morphological phenotype. Altogether, the results suggest that 5- AzaC preferentially activates certain genes.
