The lncRNA MALAT1 is upregulated in urine of type 1 diabetes mellitus patients with diabetic kidney disease.

Long non-coding RNAs (lncRNAs) are RNAs with >200 nucleotides that are unable to encode proteins and are involved in gene expression regulation. LncRNAs have a key role in many physiological and pathological processes and, consequently, they have been associated with several human diseases, including diabetes chronic complications, such as diabetes kidney disease (DKD). In this context, some studies have identified the dysregulation of the lncRNAs MALAT1 and TUG1 in patients with DKD; nevertheless, available data are still contradictory.

Polymorphisms in and genes are associated with protection against diabetic retinopathy in a Brazilian population.

Objective: The objective of this study was to investigate the association between SNPs in the and genes and diabetic retinopathy (DR).

Subjects And Methods: This study comprised 603 patients with type 2 diabetes mellitus (T2DM) and DR (cases) and 388 patients with T2DM for more than 10 years and without DR (controls). The rs639225 (A/G) and rs638203 (A/G) SNPs and the rs4324901 (G/T) and rs2507800 (T/A) SNPs were genotyped by real-time PCR using TaqMan MGB probes.

The A allele of the rs759853 single nucleotide polymorphism in the gene confers risk for diabetic kidney disease in patients with type 2 diabetes from a Brazilian population.

Objective: The gene encodes an enzyme that catalyzes the reduction of glucose into sorbitol. Chronic hyperglycemia in patients with diabetes mellitus (DM) leads to increased AKR1B1 affinity for glucose and, consequently, sorbitol accumulation. Elevated sorbitol increases oxidative stress, which is one of the main pathways related to chronic complications of diabetes, including diabetic kidney disease (DKD).

The rs2442598 polymorphism in the gene is associated with risk for diabetic retinopathy in patients with type 1 diabetes mellitus in a Brazilian population.

Objective: As studies have reported the involvement of angiopoietin-2 (ANGPT-2) in the pathogenesis of diabetic retinopathy (DR), the aim of this study was to investigate the association between the rs2442598 polymorphism and DR.

Methods: This case-control study comprised 107 patients with type 1 diabetes mellitus (T1DM) and DR (cases) and 129 patients with T1DM without DR (controls) and with ≥ 10 years of DM. The rs2442598 (G/A) polymorphism was genotyped by real-time PCR using TaqMan MGB probes.

The Impact of lncRNAs in Diabetes Mellitus: A Systematic Review and Analyses.

Long non-coding RNAs (lncRNAs) are non-coding transcripts that have emerged as one of the largest and diverse RNA families that regulate gene expression. Accumulating evidence has suggested a number of lncRNAs are involved in diabetes mellitus (DM) pathogenesis. However, results about lncRNA expressions in DM patients are still inconclusive.
