A brand new research by researchers at Lund College helps the notion that sufferers with type 2 diabetes affected person must be divided into subgroups and given individualized remedy. The research demonstrates that there are distinct epigenetic variations between different teams of sufferers with type 2 diabetes. The epigenetic markers are additionally associated with different risks of developing widespread complications in type 2 diabetes, equivalent to stroke, coronary heart assault and kidney illness.
“We present that there are distinct epigenetic variations between subgroups of sufferers with type 2 diabetes. The epigenetic markers are associated with different risks of developing widespread complications in diabetes, equivalent to coronary heart assault, stroke, and kidney illness,” says Charlotte Ling, professor of diabetes and epigenetics at Lund College and lead writer of the research, revealed in Diabetes Care.
An acclaimed research by researchers at Lund College Diabetes Centre (LUDC), revealed in 2018, demonstrated that it’s doable to divide type 1 diabetes and type 2 diabetes into 5 subgroups. In November 2021, the identical authors revealed a brand new research which highlighted genetic variations between the 4 subgroups of type 2 diabetes, suggesting different causes of the illness.
The newest research by LUDC-researcher Charlotte Ling and her colleagues reveals that there are additionally epigenetic variations between the 4 subgroups with type 2 diabetes. The epigenetic markers might be developed to foretell widespread complications of type 2 diabetes, which might enable for tailor-made remedies of sufferers.
“Many sufferers with type 2 diabetes sufferers are provided commonplace remedies by the well being care system, however rising proof means that these sufferers want tailor-made remedies. Our new research provides to the proof base that it’s clinically related to categorise sufferers with type 2 diabetes into subgroups to permit for extra personalised remedies,” says Charlotte Ling, who leads a analysis group in diabetes and epigenetics at Lund College Diabetes Centre.
The brand new research encompasses 533 people just lately identified with type 2 diabetes from two population-based cohorts in Sweden. The authors measured DNA methylations in the blood at 800.000 websites in the genome of all members. DNA methylation is a chemical course of by way of which methyl teams connect to the DNA molecule, affecting the perform of genes. The researchers discovered that the 4 subgroups had different ranges of DNA methylation at 4.465 websites.
The findings had been used to develop epigenetic danger scores to foretell widespread complications of type 2 diabetes. Epigenetic markers associated with two of the subgroups might predict an elevated danger of developing coronary heart assault, stroke, and kidney illness.
Coronary heart assault and stroke are chargeable for most deaths amongst sufferers with type 2 diabetes. Kidney illness causes rather a lot of struggling and may be very pricey for society, as many sufferers want dialysis remedy. An epigenetic biomarker that may predict complications at an early stage would make preventive actions doable.”

The authors might want to confirm their outcomes in different population-based cohorts. They’re additionally planning to check DNA methylation in tissues from, for instance, muscle, adipose tissue, liver, and the pancreas of the 4 subgroups with type 2 diabetes.
