Through genome-wide CRISPR-Cas9 screening, we identified the adenosine triphosphatase (ATPase) valosin-containing protein (VCP) as a critical dependency in CCA. Compound screens revealed that the VCP inhibitor CB-5339 potently suppresses CCA proliferation in a panel of patient-derived organoids by inducing cellular senescence. It is known that senescent cells persist, and this can contribute to therapy resistance. To address this, we combined CB-5339 with senolytic agents (ABT-263 and conatumumab), which selectively eliminate senescent CCA cells, resulting in enhanced tumor suppression both in vitro and in vivo. Clinical analysis showed that VCP overexpression in CCA patients correlates with poor prognosis. Our study unveils a \u201cone-two punch\u201d strategy, targeting VCP-mediated senescence followed by senolytic clearance, offering a promising therapeutic approach for CCA.<\/jats:p>","DOI":"10.1073\/pnas.2519568122","type":"journal-article","created":{"date-parts":[[2025,9,24]],"date-time":"2025-09-24T16:43:12Z","timestamp":1758732192000},"update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":1,"title":["CRISPR
