A Cohort Study of Tumoral LINE-1 Hypomethylation and Prognosis in Colon Cancer

Genome-wide DNA hypomethylation plays has an important role in genomic instability and colorectal carcinogenesis. However, the relationship between cellular DNA methylation level and patient outcome remains uncertain. Using 643 colon cancers in two independent prospective cohorts, we quantified DNA methylation in repetitive long interspersed nucleotide element-1 (LINE-1) elements...

Association of Ets-related transcriptional factor E1AF expression with overexpression of matrix metalloproteinases, COX-2 and iNOS in the early stage of colorectal carcinogenesis

It is now becoming clear that matrix metalloproteinases (MMPs) play a key role in tumor development and growth. MMPs are overexpressed in a variety of premalignant tumor tissues, including colorectal adenoma. Little is known about the mechanisms underlying the overexpression of MMPs in adenoma tissues. E1AF, an Ets family transcriptional factor, has been shown to play an...
