Hippo pathway monomerizes STAT3 to regulate prostate cancer growth.

ABSTRACT: Prostate cancer ranks among the most commonly diagnosed malignancies for men and has become a non-negligible threat for public health. Interplay between inflammatory factors and cancer cells renders inflammatory tissue environment as a predisposing condition for cancer development. The Hippo pathway is a conserved signaling pathway across multiple species during evolution that regulates tissue homeostasis and organ development. Nevertheless, whether Hippo pathway regulates cancer-related inflammatory factors remains elusive. Here, we show that high cell density-mediated activation of the Hippo pathway blunts STAT3 activity in prostate cancer cells. Hippo pathway component MST2 kinase phosphorylates STAT3 at T622, which is located in the SH2 domain of STAT3. This phosphorylation blocks the
