Cím:	Hypomethylation of the decorin proteoglycan gene in human colon cancer / Róza Ádány, Renato V. Iozzo
Dátum:	1991
Megjegyzések:	We have previously reported that the connective tissue stroma of human colon carcinoma contains elevated amounts of decorin, a small proteoglycan involved in the regulation of matrix formation and cell proliferation. These biochemical changes were correlated with increased mRNA levels and general hypomethylation of the decorin gene in human colon cancer DNA. In this report we use a quantitative polymerase chain reaction method coupled with digestion of the DNA template by methylation-sensitive restriction endonucleases to investigate in detail the location of hypomethylated sites in decorin gene. We demonstrate that a specific site in the 3' region of the gene, encompassing codons 360-361, is specifically hypomethylated in both colon carcinoma and benign polyp. In contrast, three HpaII sites, clustered in the 5' untranslated region, show full methylation in normal and neoplastic DNA. The lack of such changes in ulcerative colitis DNA suggests that chronic inflammation alone is not sufficient to alter cytosine methylation in the decorin gene. These results suggest the possibility that the 3' region of the decorin-coding sequence may be involved in the control of decorin gene expression.
