Although cyclin D1, a G1/S phase cell cycle regulatory protein at this locus, is considered as a key driver of malignant progression, further exploration is needed to develop more effective targets for cases with this amplification. Using CRISPR-based gene knockout screening of genes located in chr11q13.3, we found that loss of the gene encoding the Fas-associated death domain (FADD) protein, a well-recognized adaptor to caspase-8 that induces cell apoptosis, significantly reduced cancer cell proliferation. FADD expression was elevated in chr11q13.3 amplified tumors and correlated with poor prognosis. RNA-sequencing, mass spectrometry, and proteomics analyses revealed a direct relationship between FADD and the DNA helicase MCM5 in the S phase. FADD and cyclin D1 acted at different stages of the cell cycle to synergistically induce proliferation, and caspase-8 deficiency was required for the oncogenic activity of FADD. In a patient-derived xenograft model with chr11q13.3 amplification, combined administration of DNA helicase complex inhibitor and CDK4/6 inhibitor effectively curtailed tumor growth. Overall, this study identified a non-classical oncogenic role for FADD in mediating tumor progression in HNSCC and provided a feasible treatment option for patients with chr11q13.3 amplification. Overall design: RNA-seq profiling in HN4 cell stably transfected with full-length FADD or control."],"repository":["ENA"],"additional_accession":[]},"is_claimable":false,"name":"FADD Functions as an Oncogene in Chr11q13.3 Amplified Head and Neck Squamous Cell Carcinoma","description":"FADD Functions as an Oncogene in Chr11q13.3 Amplified Head and Neck Squamous Cell Carcinoma","dates":{"last_updated":"2025-09-24","first_public":"2025-02-22"},"accession":"PRJNA1224430","cross_references":{"GEO":["GSE289740"],"taxon":["9606"]}}
