INSR gene expression in African-American and Caucasian paired breast tissue samples assessed by Real Time-PCR (RT-PCR). (A–D) shows INSR-A and INSR–B gene expression represented as fold change after normalization using GAPDH as an internal control. (A–B) show INSR-A and INSR-B mRNA fold change between AAN and CAN for pre- and post-menopausal samples. (C–D) show INSR-A and INSR-B mRNA fold change between ER (+) and ER (−) AAM and CAM pre- and post-menopausal samples. AAN = African-American normal tissue, AAM = African-American malignant tissue, CAN = Caucasian normal tissue and CAM = Caucasian malignant tissue. Total number of patients (n) analyzed per group was as follows: AAN= 23, AAM=27, CAN=20 and CAM=24.
