For example, more intense infiltration of malignant lesions by lymphocytes was observed in specimens of medullary breast carcinoma displaying elevated expression of CD54 (ICAM-1) and CD106 (VCAM-1) as compared with ductal breast carcinoma displaying diminished expression of these CAMs (Bouma-ter Steege et al, 2004). The gene discussed is ICAM1; the disease is medullary breast carcinoma.
