DNMT3B plays antagonistic roles with SMARCB1 and is a targetable vulnerability in rhabdoid tumors.
PURPOSE Rhabdoid tumors (RTs) are highly aggressive pediatric cancers driven by the biallelic inactivation of the SMARCB1 tumor suppressor gene, the sole recurrent genetic alteration. SMARCB1 encodes a core subunit of the SWI/SNF chromatin remodeling complex; its loss disrupts epigenetic gene regulation, supporting the...
