Recent data suggest the SWI/SNF chromatin remodeling complex may also act as a tumor suppressor. Utilizing a reversibly inactivating conditional allele, we demonstrate that loss of Snf5/Ini1/Baf47/SmarcB1, a core subunit of SWI/SNF, results in highly penetrant cancer predisposition with 100% of mice developing mature CD8(+) T cell lymphoma or rare rhabdoid tumors with a median onset of only 11 weeks. Notably, while loss of Snf5 predisposes to aggressive cancers, it is also required for survival of virtually all nonmalignant cells in vivo. Reversible gene targeting demonstrates a critical and specific role for Snf5 in tumor suppression, provides a novel system in which to explore the genetic pathways involved in tumor suppression by Swi/Snf, and should be of wide use in evaluating other essential tumor suppressor genes.
