Brg1 pathology outlines
WebBRG1, a tumor suppressor, is part of the human switch/sucrose non-fermentable (SWI/SNF) complex [BRG1/BRM associated factor (BAF) complex] which is involved in chromatin remodeling (3-6). SMARCA4 -UT are characterized by a poorly differentiated morphology with at least a subset of these tumors exhibiting focal rhabdoid features . WebBRG1 and BRM, two core catalytic subunits in SWI/SNF chromatin remodeling complexes, have been suggested as tumor suppressors, yet their roles in carcinogenesis are …
