title: Transformation of NIH3T3 cells with ras oncogenes abrogates the retinoic acid induction of tissue transglutaminase.
abstract: Retinoic acid greatly increases enzyme activity and mRNA expression of the tissue-type transglutaminase enzyme in NIH3T3 cells. This response is blocked in cells transformed with activated H-ras, K-ras or N-ras oncogenes, but not in pSVneo vector transfected cells. Lack of induction by RA of the tissue-type TGase in these ras-transformed fibroblasts suggests intersecting pathways between retinoid action and the ras oncogene.
