YAP-TEAD signaling promotes Basal Cell Carcinoma development via c-JUN/AP1 axis [RNA-seq]

Project description:The mammalian Hippo signaling pathway, through its effectors YAP and TAZ, coerces epithelial progenitor cell expansion for appropriate tissue development or regeneration upon damage. Its ability to drive rapid tissue growth explains why many oncogenic events frequently exploit this pathway to promote cancer phenotypes. Indeed, several tumor types including basal cell carcinoma (BCC) show genetic aberrations in the Hippo (or YAP/TAZ) regulators. Here, we uncover that while YAP is dispensable for homeostatic epidermal regeneration, it is required for BCC development. Our clonal analyses further demonstrate that few emerging Yap-null dysplasia have lower fitness and thus are diminished as they progress to invasive BCC. Mechanistically, YAP depletion in BCC tumors leads to effective impairment of the JNK-JUN signaling, a well-established tumor driving cascade. Importantly, in this context, YAP does not influence canonical Wnt or Hedgehog signaling. Overall, we reveal the Hippo signaling as an independent promoter of BCC pathogenesis and thereby a viable target for drug-resistant BCC.

A non-canonical repressor function of JUN restrains YAP activity and suppresses YAP-dependent liver cancer growth [3prime_Seq_JUNoe]

Project description:The transcriptional coactivators YAP/TAZ are the critical downstream regulators of the Hippo pathway that regulate gene expression in response to changes in pathway activity, mainly by binding to TEAD transcription factors. Uncontrolled transcriptional output of YAP/TAZ can lead to rapid induction of aggressive tumor growth. AP-1 is a dimeric basic leucine zipper (bZIP) transcription factor complex with JUN and FOS proteins being the most abundant members of this family. Unlike FOS, JUN can also form homodimers, but in the cell, JUN presumably preferentially forms heterodimers with members of the FOS family, which act as potent transcriptional activators. Previous studies identified substantial co-occupancy of YAP/TAZ and AP-1 at genomic sites, and they demonstrated that JUN/FOS heterodimers cooperate with the YAP/TAZ and TEAD transcription factors to drive YAP/TAZ target gene expression. Here, we now elucidate a negative feedback mechanism in which high YAP activity is restrained by the recruitment of homodimeric JUN::JUN/NCOR1 repressor complexes and show that this noncanonical JUN function is part of a tumor suppressor mechanism in the liver.
