WebBackground. The SMARCA4 catalytic ATPase, can be inactivated by several types of genomic alterations (GA) in NSCLC. SMARCA4 deficient (d) NSCLC is an aggressive subtype of primary lung adenocarcinoma that is often confused with metastatic disease to the lung. WebThe SMARCA4 gene provides instructions for making a protein called BRG1, which forms one piece (subunit) of several different protein groupings called SWI/SNF protein complexes. SWI/SNF complexes regulate gene activity (expression) by a process known as chromatin remodeling. Chromatin is the network of DNA and protein that packages DNA into ...
WebThe SMARCA subgroup of genes belong to the SWI1/SNF1 family that provide instructions for making chromatin remodeling and repair. Chromatin is highly condensed DNA and protein that forms chromosomes within the nucleus of eukaryotic cells, and the structure can be remodeled to alter how tightly DNA is packaged. WebDec 6, 2024 · SMARCA4/BRG1 immunohistochemistry was performed on all tumors diagnosed as SNUC, poorly differentiated carcinoma, NEC, and TCS during a 12-year period.
