SMARCA4 and colorectal carcinoma: Despite previous reports showing that β-catenin expression in the nuclei can be a prognostic marker in CRC patients (Horst et al, 2008), and that BRG1 directly interacts with β-catenin to promote target gene activation (Barker et al, 2001), our results show that BRG1 expression is significantly associated with cyclin D1 expression but not nuclear β-catenin expression.
