1 Protection against malignant conversion in SENCAR mouse skin by all trans retinoic acid: inhibition of the ras p21-processing enzyme farnesyltransferase and Ha-ras p21 membrane localization. Tretinoin cyclin-dependent kinase inhibitor 1A (P21) Mus musculus
2 Protection against malignant conversion in SENCAR mouse skin by all trans retinoic acid: inhibition of the ras p21-processing enzyme farnesyltransferase and Ha-ras p21 membrane localization. Tretinoin cyclin-dependent kinase inhibitor 1A (P21) Mus musculus
3 In this study, we assessed whether the protective effect of RA against malignant conversion involves the inhibition of ras p21 processing in those tumors that contain the activated ras oncogene. Tretinoin cyclin-dependent kinase inhibitor 1A (P21) Mus musculus
4 Furthermore, the tissue samples from RA-treated groups in different protocols also showed significantly diminished membrane localization of Ha-ras p21, with a concomitant increase in cytosolic Ha-ras p21 levels. Tretinoin cyclin-dependent kinase inhibitor 1A (P21) Mus musculus
5 Furthermore, the tissue samples from RA-treated groups in different protocols also showed significantly diminished membrane localization of Ha-ras p21, with a concomitant increase in cytosolic Ha-ras p21 levels. Tretinoin cyclin-dependent kinase inhibitor 1A (P21) Mus musculus
6 Taken together, these results indicate a strong correlation between the inhibition of ras p21 farnesylation because of a decrease in FTase activity by RA and its protective effect against malignant conversion of papillomas to carcinomas.
