TGF-? upregulates the translation of USP15 via the PI3K/AKT pathway to promote p53 stability.


ABSTRACT: Crosstalk between transforming growth factor beta (TGF-?) signaling and p53 has a critical role in cancer progression. TGF-? signals via Smad and non-Smad pathways. Under normal conditions, wild-type p53 forms a complex with Smad2/3 and co-activates transcription of a variety of tumor suppressor genes, resulting in tumor suppressive effects. Thus, p53 stability is essential in progression of tumor suppressive responses mediated by TGF-? signaling. However, it remains unknown whether p53 stability is regulated by TGF-?. In the current study, we identify that USP15 binds to and stabilizes p53 through deubiquitination in U2OS and HEK293 cells. TGF-? promotes the translation of USP15 through activation of mammalian target of rapamycin by the phosphoinositide 3-kinase/AKT pathway. Upregulation of USP15 translation links the crosstalk between TGF-? signaling and p53 stability, allowing this cytokine to have a critical role in cancer progression.
