TP53 and cancer: When comparing TP53 expression levels among TP53-mutated (truncating mutations and non-truncating mutations) cancers, TP53-wildtype cancers and normal tissue, we found that TP53 expression is consistently lower in TP53-truncated cancers compared to other cancers or normal tissue, while TP53 expression is often higher in TP53-mutated but TP53-non-truncating cancers compared to other cancers or normal tissue.
