Hippo signaling represents a tumor suppressor pathway that regulates organ size and tumorigenesis through phosphorylation and inhibition of the transcription coactivator YAP. Here, we show that serum deprivation dramatically induces YAP Ser127 phosphorylation and cytoplasmic retention, independent of cell-cell contact. Through chemical isolation and activity profiling, we identified serum-derived...
Eukaryotic cells counteract oxidative and other environmental stress through the activation of Nrf2, the transcription factor that controls the expression of a host of protective enzymes by binding to the antioxidant response element (ARE). The electrophilic molecules that are able to activate Nrf2 and its downstream target genes have demonstrated therapeutic potential in carcinogen-induced tumor...
