These can be used to quickly identify common problems with NGS data and QC individual sequencing runs before starting biological analysis. The TMB-H and MSI-H ratios corresponding to SWI/SNF-mutant tumors were also significantly higher than those corresponding to the SWI/SNF-non-mutant tumors (TMB-H ratio: 44.3% vs. 10.3%, p <0.0001; MSI-H ratio: 16.0% vs. 0.9%, p <0.0001), even though the differences were not significant for certain malignancies, such as kidney cancer, pancreatic cancer, prostate cancer, and urothelial cancer. For example, the BRD2 inhibitor, JQ1, can suppress ARID1A-deficient ovarian clear cell cancer cells because BRD2 inhibition decreases ARID1B transcription [48]. 2021;40:363754. Therefore, SWI/SNF-deficient cancers are vulnerable to the inhibition of homologous recombination repair factor, PARP1 [20, 49], cell cycle regulator, cyclin-dependent kinase (CDK)4/CDK6 [28, 56], DNA replication checkpoint factor, ATR [57], chromosomal segregation factor, Aurora kinase A [58], and oxidative phosphorylation [59] and glutathione [60] pathways.
