When excluding sites with negative changes, 10 genes (BNIP3, BRCA1, CCND1, CDKN2A, HTATIP2, ITGAV, NFKB1, PIK3R1, PRDM16 and PTX3) showed significantly different methylation levels among cancer lesions, remote normal-appearing tissues, and healthy controls. The gene discussed is ITGAV; the disease is cancer.
