Telomerase activity during spontaneous immortalization of Li-Fraumeni syndrome skin fibroblasts.

Abstract excerpt

Li-Fraumeni Syndrome (LFS) is characterized by heterozygous germline mutations in the p53 gene. Accompanied by genomic instability and loss or mutation of the remaining wild type p53 allele, a low frequency of spontaneous immortalization in LFS fibroblasts occurs. It is believed that the loss of p53 wild type function contributes to immortalization of these LFS fibroblasts, but it is not clear if this is...
