Adenomatous polyps in the gastrointestinal system rarely occur in childhood and are accompanied by syndromes such as Familial adenomatous polyposis, attenuated familial adenomatous polyposis, and MUTYH-associated polyposis, Gardner and Turcot syndrome, and also mismatch repair (MMR) gene defects.
TIMP-1 mRNA was detected in 2 of 7 adenomatous polyps in the adenoma area: in both cases associated with focal stromal inflammation at the epithelial-stromal interface.
DNMT3B levels of immunohistochemical expression increased significantly (p < 0.001) from normal to hyperplastic and from adenomatous polyps to carcinoma samples.
SFRP2 and IGF2 DMR0 showed significant methylation changes at the adenomatous polyp stage, followed by the CIMP markers CDKN2A and hMLH1 at the adenocarcinoma stage.
TAS2R38 bitter taste genetics, dietary vitamin C, and both natural and synthetic dietary folic acid predict folate status, a key micronutrient in the pathoaetiology of adenomatous polyps.
BVES was found to be underexpressed in all stages of human colorectal carcinoma (CRC) and in adenomatous polyps, indicating its suppression occurs early in transformation.
MFAP5 may facilitate the distinction between pseudoinvasion and true invasive cancer in colonic adenomatous polyps with a sensitivity of 80% (confidence interval 44-96%) and a specificity of 75% (confidence interval 43-93%) in this small cohort.
Adenomatous polyps of the appendix frequently had APC, KRAS and TP53 mutations and were morphologically and molecularly similar to adenomatous polyps of the colorectum.
