Circulating long noncoding RNA signatures associate with incident diabetes in older adults: a prospective analysis from the VITA cohort study
Objective: Long noncoding RNAs (lncRNAs) are involved in diabetogenesis in experimental models yet their role in humans is unclear. We investigated whether circulating lncRNAs associate with incident type 2 diabetes in older adults.
Research Design and Methods: A preselected panel of lncRNAs was measured in serum of individuals without diabetes (n=296) from the VIenna Transdanube Aging (VITA) study, a prospective community-based cohort study. Participants were followed-up over 7.5 years. A second cohort of individuals with and without type 2 diabetes (n=90) was employed to validate our findings.
Results: Four lncRNAs (ANRIL, MIAT, RNCR3, and PLUTO) were associated with incident type 2 diabetes and linked to HbA1c trajectories throughout the 7.5-year follow-up. Similar results (for MIAT and PLUTO also in combined analysis) were obtained in the validation cohort.
Conclusion: We found a set of circulating lncRNAs which independently portends incident type 2 diabetes in older adults years before disease onset.
