Differential genetic susceptibility of cultured human skin fibroblasts to transformation by Kirsten murine sarcoma virus.
Hereditary adenomatosis of the colon and rectum (ACR), an autosomal dominant trait, is associated with a predisposition to neoplasia. The present study describes the differential genetic susceptibility of cultured human skin fibroblasts to transformation by Kirsten murine sarcoma virus. Primary cutaneous outgrowths were derived from normal appearing subepidermal biopsies of ACR phenotypes and appropriate controls. Exponentially growing cell cultures from ACR subjects and a portion of the clinically asymptomatic ACR progeny subjected to the viral probe were 100-1000 fold more susceptible to transformation than were normal skin fibroblast cultures. The virally transformed human skin fibroblasts showed a loss of anchorage dependency in carboxymethylcellulose suspension and formed tumors in athymic mice. The results suggest that skin fibroblasts obtained from individuals gine sarcoma virus.[1]References
