Background/aim: The role of brahma-related gene 1 (BRG1)-associated factor 57 (BAF57), a transcription factor, has been determined in prostate, breast, and ovarian cancer. However, the relationship between BAF57 and colorectal cancer (CRC) is obscure. Thus, we examined the functional correlation between BAF57 expression and oncological malignancy in CRC in vitro.
Materials And Methods: BAF57 expression in WiDr and HT29 CRC cell lines and clinical specimens from CRC patients was analysed by western blotting and/or RT-PCR. BAF57 expression was down-regulated in WiDr cells through siRNA transfection. An invasion assay was also performed to assess malignancy.
Results: BAF57 was expressed in both human CRC cell lines. Overall survival and recurrence-free survival rates were significantly reduced in high BAF57-expressing specimens. BAF57 expression was an independent predictive factor for long-term survival.
Conclusion: BAF57 correlates with oncological malignancy and may be a novel therapeutic target in CRC.

The multi-subunit ATP-dependent chromatin remodeling factor SWI/SNF complex is a fundamental regulator of gene transcription. The SWI/SNF complex in mammals, also called the BAF complex, consists of 9-12 subunits. Genomic functional studies have found that 20%-25% of human cancers are caused by mutations in genes encoding this complex.

The SWItch/Sucrose Non-Fermentable (SWI/SNF) complexes are ubiquitous ATP dependent chromatin remodeling complexes that provide epigenetic regulation of gene expressions across the genome. Different combination of SWI/SNF subunits allow tissue specific regulation of critical cellular processes. The identification of SMARCB1 inactivation in pediatric malignant rhabdoid tumors provided the first example that the SWI/SNF complex may act as a tumor suppressor.

Cyclin D1 regulates cyclin-dependent protein kinase activity of the cell cycle, and alternative splicing generates a isoform, acting as a mediator of aberrant cellular proliferation. As alternative splicing processes are sensitive to mechanical stimuli, whether the alternative splicing of is regulated by mechanical stress and what kinds of factors may act as the regulator of mechano-induced alternative splicing remain unknown. The alternative splicing of was examined using reverse transcription polymerase chain reaction (RT-PCR) in osteoblast cell lines and keratinocyte cells loaded by a cyclic stretch.

The BAF complex (SWI/SNF) is an ATP-dependent chromatin remodeler that adapts the structural organization of the chromatin. Despite a growing understanding of the composition of BAF in different cell types, the interaction network within the BAF complex is poorly understood. Here, we characterized an isoform of the BRG1/SMARCA4 ATPase expressed in human neural progenitor cells.
