ANXA1 and breast neoplasm: ANXA1 expression is related with the carcinogenesis process [13–15] and with metastasis formation in many tumors [16–18], including breast tumors [19–23], where we and others have shown that ANXA1 overexpression is associated with high pathological differentiation grade, lack of hormone receptor expression and a basal-like phenotype [20, 24, 25].
