SMARCA4 and breast cancer: The S613 locus of SMARCA4 exhibits a higher phosphorylation level in several tumor tissues compared with normal tissues, including breast cancer, colon cancer and UCEC (Figure 4B, all p< 0.05), followed by an increased phosphorylation level of the S695 locus for breast cancer (p = 3.65e−06), UCEC (p = 2.34e−09), and LUAD (p = 5.72e−33).
