Expression of HGF and miR-7 is strongly associated in normal breast tissue. Expression of HGF (A) and miR-7 (B) was examined by qPCR in 41 pairs of breast cancer tissues and nearby normal tissues and represented by dot plots. Association between HGF and miR-7 was determined in breast normal (C) and cancer tissues (D) by linear regression, and represented by the coefficient of determination (R 2).
