TP53 and neoplasm: As Figure 5C shows, there is no difference in the protein expression of wild-type TP53 and mutant TP53 in LFS cells suggesting that the wild-type allele activity of TP53 in LFS cells may not be as potent in its tumor suppression ability especially in curbing cell proliferation as wild-type TP53 found in normal non-LFS cells [43].
