AIF1v1 expression in breast tumors significantly and positively correlated with age (p = 0.02), menopausal status (p = 0.05) and breast adipose expression of Cytochrome P450 Family 19 Subfamily A Member 1 (CYP19A1) (p = 0.03) and IL-6 (p = 0.006) whereas AIF1v3 was only positively correlated with breast adipose expression of cyclooxygenase-2 (COX2) (p = 0.04). This evidence concerns the gene CYP19A1 and breast neoplasm.
