Project description:Loss-of-function mutations in SWI/SNF chromatin remodeling subunit genes are observed in many cancers, but an oncogenic role for SWI/SNF is not well established. Here we reveal that ACTL6A, encoding a SWI/SNF subunit linked to stem and progenitor cell function, is frequently co-amplified and highly expressed together with the p53 family member p63 in head and neck squamous cell carcinoma (HNSCC). ACTL6A and p63 physically interact and cooperatively control a transcriptional program that promotes proliferation and suppresses differentiation, in part through activation of the Hippo-YAP pathway via regulators including WWC1. Consequently, loss of ACTL6A or p63 in tumor cells induces YAP phosphorylation and inactivation, associated with growth arrest and terminal differentiation, all phenocopied by WWC1 overexpression. In vivo, ectopic ACTLC6A/p63 expression promotes tumorigenesis, while ACTL6A expression and YAP activation are highly correlated in primary HNSCC and predict poor patient survival. Thus, ACTL6A and p63 collaborate as oncogenic drivers in HNSCC. Gene expression profiling of HNSCC cells with and without ablated endogenous ACTL6A via lentiviral shRNA.

Project description:Dysregulation of the Hippo pathway and the consequent activation of its downstream targets, the transcriptional co-activators YAP and TAZ (YAP/TAZ), drives oncogenic transcriptional programs upon binding TEAD transcription factors in multiple human malignancies. The recent development of small molecule TEAD inhibitors (smTEADi) provides an opportunity to therapeutically target Hippo pathway dysregulation in cancer. In this regard, HPV-negative head and neck squamous cell carcinoma (HNSCC) harbor multiple genetic alterations that promote YAP/TAZ hyperactivation, raising the possibility that HNSCC cells might be dependent on YAP/TAZ-TEAD driven oncogenic transcriptional programs. To test this hypothesis, we examined the antitumor activity of the novel smTEADi, SW-682 and genetically encoded TEAD inhibitor peptide (pTEADi) in Cal33 HPV-negative HNSCC cell line-derived xenograft model. To elucidate the transcriptomic changes upon YAP/TAZ-TEAD inhibition, RNA extracted from xenograft tumors treated with SW-682 or pTEADi, as well as control, was subjected to RNA sequencing.

Project description:The Hippo pathway downstream effectors, Yap and Taz, play key roles in cell proliferation and tissue growth, regulating gene expression especially via interaction with Tead transcription factors. To investigate their role in skeletal muscle stem cells, we analysed gene expression changes driven by Taz and compared these to Yap mediated changes to the transcriptome by measurement of gene expression on Affymetrix microarrays. To interrogate overlapping and unique transcriptional changes driven by these Hippo effectors, satellite cell-derived myoblasts were transduced with constitutively active TAZ S89A or YAP S127A retrovirus for 24h or 48h, with empty retrovirus as control. Triplicate microarray analyses of empty vector controls, hYAP1 S127A and TAZ S89A transgenic primary myoblasts were conducted.
