BRD2 and breast cancer: In contrast, the expression levels of ADK-S was not significantly different in breast cancer tissues compared to that of paired NAT controls for the whole group analysis (paired t-test, t=0.1929, df=45, p= 0.8479) (Figure 1A, 1B); similarly, further analysis based on subtypes of breast cancer did not reveal different ADK-S expression levels between cancer versus NAT controls (Figure 1C).
