    ..HYMAI and ZAC/LOT1 are therefore candidate genes involved in TNDM. Furthermore, the human chromosome 6q24 region is syntenic to mouse chromosome 10 and represents a novel imprinted domain. ..

    ..In conclusion, absence or reduction of CDX1 expression in CRC seems to be primarily regulated by promoter methylation and is probably selected for because of its impact on the differentiation of colonocytes. ..

    ..Thus, the deacetylase-dependent pathway by which MBD1 actively silences methylated genes is likely to be different from that utilized by the methylation-dependent repressors MeCP1 and MeCP2. ..

    ..We have thus shown an in vitro link between phosphoinositide 3-kinase-mediated HOXA9/HOXA10 expression, and a drug-resistant, progenitor cell phenotype in MGMT-independent pediatric glioblastoma. ..

    ..We thus conclude that methylation of the p16 gene promoter shows promise as a predictor for malignant transformation (Fisher's exact, P = 0.002) in a subset of patients. ..

    ..In addition, conditioned medium from SLIT2-transfected COS-7 cells reduced cell growth and induced apoptosis in SW48 colorectal tumor cell line. In conclusion, SLIT2 is an excellent candidate tumor suppressor gene for colorectal cancer. ..

    ..We therefore propose that environmentally induced changes in promoter-enhancer interactions represent a fundamental epigenetic mechanism by which nutrition and aging can influence long-term health. ..
