Fig. 4From: The hypermethylation of p16 gene exon 1 and exon 2: potential biomarkers for colorectal cancer and are associated with cancer pathological stagingThe methylation levels of p16 gene body in 30 CRC patients. a The methylation levels of p16 exon 1 region. b The methylation levels of p16 exon 2 region. Each sample was measured three times. c The methylation differences between p16 exon 1 and exon 2. Data was means ± standard errors. **p < 0.01Back to article page
