STAT1 and breast cancer: Breast Cancer Gene-Expression Miner v4.4 was used to further analyze the expression of CNN1 and STAT1 in different subtypes of breast cancer, indicating that the expression of CNN1 and STAT1 is markedly different in invasive ductal carcinoma (IDC), invasive lobular carcinoma (ILC), micropapillary, mucinous, and triple negative breast cancer (TNBC) (Figure 1E).
