Webb13 apr. 2024 · Along with these changes, an increase in the mRNA levels of p53 and PTEN genes was also observed. p53 gene mutation is reported in more than 50% of all human cancers leading to their low expression levels. p53 protein is a key regulator that controls the replication of faulty DNA, and, hence, low-level expression of p53 leads to cancer. WebbThese data suggest that the p19 ARF –p53 pathway is a critical regulator of the senescence response in murine fibroblasts, whereas the p16 INK4A –pRb pathway is not. Genetic inactivation of the p16INK4A or Rb tumor suppressor genes alone is not sufficient to immortalize MEFs ( Krimpenfort et al. 2001; Peeper et al. 2001 ).
