abstract = {Development of type 2 diabetes depends on environmental and
genetic factors. We investigated the epigenome-wide
association of prevalent diabetes with DNA methylation
(DNAm) in peripheral blood.DNAm was measured in whole blood
with the Illumina Infinium HumanMethylation450 BeadChip in
two subsamples of participants from the ESTHER cohort study.
Cohort 1 included 988 participants, who were consecutively
recruited between July and October 2000 and cohort 2
included 527 randomly selected participants. The association
of DNAm with prevalent type 2 diabetes at recruitment was
estimated using median regression analysis adjusting for
sex, age, BMI, smoking behaviour, cell composition and batch
at 361,922 CpG sites.Type 2 diabetes was prevalent in $16\%$
of the participants, and diabetes was poorly controlled in
$45\%$ of the diabetic patients. In cohort 1 (discovery)
DNAm at 39 CpGs was significantly associated with prevalent
diabetes after correction for multiple testing. In cohort 2
(replication) at one of these CpGs, DNAm was still
significantly associated. Decreasing methylation levels at
cg19693031 with increasing fasting glucose and HbA1c
concentrations were observed using restricted cubic spline
analysis. In diabetic patients with poorly controlled
diabetes, the decrease in estimated DNAm levels was
approximately $5\%$ in comparison with participants free of
diagnosed diabetes.Cg19693031, which is located within the
3-untranslated region of TXNIP, might play a role in the
pathophysiology of type 2 diabetes. This result appears
biologically plausible given that thioredoxin-interacting
protein is overexpressed in diabetic animals and humans and
3-untranslated regions are known to play a regulatory role
in gene expression.},
