WebAbnormal patterns include overexpression of p53 in the nucleus, null or complete absence of p53 expression, cytoplasmic and subclonal p53 expression [9,28]. As shown in the results of our study, overexpression is most commonly associated with non-synonymous missense mutation in TP53. This mutation results in a nuclear accumulation of a ...

WebDec 24, 2024 · Tumor-associated p53 mutations are usually associated with phenotypes distinct from those caused by the loss of the tumor-suppressing function exerted by wild-type p53protein. Many of these mutant p53 proteins have oncogenic characteristics, and therefore modulate the ability of cancer cells to proliferate, escape apoptosis, invade and … WebNov 12, 2008 · Due to the incomplete penetrance of the p53 null phenotype, a larger group of mice should be tested to verify the specific effect of p53 deficiency on PPARγ expression, in vivo. Thus, while the lack of p53 in cells that can give rise to adipocytes leads to their terminal adipogenic differentiation, p53 deficiency that may lead to upregulation ...
