Figure 7. ARID1A protein expression is low and related to poor survival in breast cancer patients. (A) Representative IHC staining of ARID1A in (a) normal tissues (n = 32) and (b) tumor tissues (n = 119) (200×). (B) The expression of ARID1A protein in tumor tissues was significantly lower than that in adjacent normal breast tissues (p<0.001). (C) Low ARID1A expression is associated with poor survival in breast cancer patients, based on a Kaplan–Meier analysis of OS (n=119, log-rank test, p=0.035).
