Abstract The most frequent genetic alterations across multiple human cancers are mutations in TP53 and the activation of PI3K/AKT pathway, two events crucial for cancer progression. Mutations lead to inhibition tumour metastasis suppressor TAp63 , a p53 family member. By performing mouse-human cross species analysis between metastatic mammary adenocarcinoma mouse model models breast progression, we identified TAp63-regulated oncogenic lncRNAs, TROLL-2 TROLL-3 . Further, using pan-cancer...
The p53 family member TP63 encodes two sets of N-terminal isoforms, TAp63 and ΔNp63 isoforms. They each regulate diverse biological functions in epidermal morphogenesis cancer. In the skin, where their activities have been extensively characterized, prevents premature aging by regulating quiescence genomic stability stem cells required for wound healing hair regeneration, while controls maintenance terminal differentiation basal cells. This functional diversity is surprising given that these...
