Transient activation of YAP/TAZ confers resistance to morusin-induced apoptosis.

ABSTRACT:

Background

The Hippo signaling pathway involves a kinase cascade that controls phosphorylation of the effector proteins YAP and TAZ, leading to regulation of cell growth, tissue homeostasis, and apoptosis. Morusin, a compound extracted from Morus alba, has shown potential in cancer therapy by targeting multiple signaling pathways, including the PI3K/Akt/mTOR, JAK/STAT, MAPK/ERK, and apoptosis pathways. This study explores the effects of morusin on YAP activation and its implications for apoptosis resistance.

Results

Our investigation revealed that morusin induces transient YAP activation, characterized by the dephosphorylation of YAP at S127 and nuclear localization, followed by gradual rephosphorylation in multiple cancer cells. Notably, this activation occurs independently
