Aging related methylation influences the gene expression of key control genes in colorectal cancer and adenoma

Figure 2 Genes showing both age- and carcinogenesis-related expression alterations. SYNE1 (spectrin repeat containing nuclear envelope protein 1), LTBP3 (latent transforming growth factor beta binding protein 3) and CLEC3B (C-type lectin domain family 3 member B) genes were downregulated during the colorectal carcinogenesis, similar decreasing expression was found during aging (significantly higher mRNA levels were detected in young colonic samples than in healthy adult biopsy specimens). MGP (matrix Gla protein) was overexpressed in children and in CRC samples compared to adenoma and healthy adults (P < 0.035), hence its opposite expression was found during aging and colorectal carcinogenesis. X axis shows the analyzed sample groups, the normalized mRNA expression can be seen on Y axis. Red dots indicate the normalized mRNA expression values, boxplots represent the medians and standard deviations. Ch: Children; N: Normal; Ad: Adenoma; CRC: Colorectal cancer.
