Investigating the expression level of CBP and GCN5 in BC tissue samples with different receptors status revealed a significantly high level of CBP expression in the ERα-positive and PR-positive BC compared to ERα- and PR-negative tissue samples (p = 0.0001 and p = 0.0001, respectively) (Table 3), whereas the expression level of GCN5 did not show a significant correlation with the status of ERα or PR hormone receptors (p = 0.213 and p = 0.541, respectively) (Table 3). The gene discussed is KAT2A; the disease is breast cancer.
