LINE‐1 hypomethylation is inversely associated with microsatellite instability and CpG island methylator phenotype in colorectal cancer
Open accessAbstract
The CpG island methylator phenotype (CIMP) with widespread promoter CpG island methylation is a phenotype in colorectal cancer, associated with microsatellite instability (MSI) and BRAF mutation. Genome‐wide hypomethylation may also play an important role in genomic instability. However, the relation between global DNA methylation level and methylation in individual CpG islands remains uncertain. Utilizing 869 population‐based colorectal cancers, we measured long interspersed nucleotide element‐1 (LINE‐1) methylation level by Pyrosequencing, which correlates with global DNA methylation level. We quantified DNA methylation in 8 CIMP‐specific promoters (CACNA1G, CDKN2A (p16), CRABP1, IGF2, MLH1, NEUROG1, RUNX3 and SOCS1) by real‐time PCR (MethyLight technology). LINE‐1 methylation levels in tumors were approximately normally distributed (mean, 61.4%; median, 62.3%; standard deviation, 9.6%). Among the 869 tumors, 128 (15%) were classified as CIMP‐high (≥6/8 methylated promoters). The mean LINE‐1 methylation level was higher in CIMP‐high tumors (65.1%, p < 0.0001) than non‐CIMP‐high tumors (60.7%), and higher in MSI‐high tumors (64.7%, p < 0.0001) than non‐MSI‐high tumors (60.7%). When tumors were stratified by MSI/CIMP status, compared to non‐MSI‐high non‐CIMP‐high tumors (mean LINE‐1 methylation level, 60.4%), the mean LINE‐1 methylation level was higher in MSI‐high CIMP‐high (64.8%, p < 0.0001), MSI‐high non‐CIMP‐high (64.6%, p = 0.03) and non‐MSI‐high CIMP‐high tumors (66.1%, p = 0.0003). In addition, 18q loss of heterozygosity in non‐MSI‐high tumors was correlated with LINE‐1 hypomethylation (p = 0.004). In conclusion, both CIMP‐high and MSI‐high are inversely associated with LINE‐1 hypomethylation, suggesting that CIMP/MSI and genomic hypomethylation may represent different pathways to colorectal cancer. Our data also support a possible link between global hypomethylation and chromosomal instability. © 2008 Wiley‐Liss, Inc.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
