Fig. 6: Breast cancer tissues express higher level of nuclear Gal-1 than corresponding non-cancerous tissues.

Serial sections were used for the immunohistochemical staining of FOXP3 and Gal-1. a Representative immunohistochemical staining for FOXP3 and Gal-1 in normal tissues and primary tumor tissues from breast cancer patient. Scale bars = 100 μm (×10) and 20 μm (×40). b The nuclear Gal-1 expression score was quantified and analyzed in the normal tissues and primary human breast cancer tissues. ***P < 0.001. b Paired t-test
