Association of SNP rs7181866 in the nuclear respiratory factor-2 beta subunit encoding GABPB1 gene with obesity and type-2 diabetes mellitus in South Indian population.

GABPB1, known as nuclear respiratory factor 2 (Nrf2), activates mitochondrial genes that are responsible for oxidative phosphorylation. Earlier studies on GABPB1 reported that two single nucleotide polymorphisms (SNPs) such as rs7181866 and rs8031031, to be associated with increased endurance in athletes. In the present study, a cohort of 302 South Indians, including normoglycemic healthy controls, T2DM with and without obesity were genotyped for the two SNPs by PCR-RFLP method and correlated with serum adipokines.

Association of single-nucleotide polymorphisms of the KEAP1 gene with the risk of various human diseases and its functional impact using in silico analysis.

Keap1, Kelch-like erythroid derived Cap 'n' collar homology (ECH) associated protein 1 is a highly redox-sensitive member of the BTB-Kelch substrate adaptor protein which acts as a major upstream regulator of Nrf2 (Nuclear factor erythroid 2-related factor 2) by Cul3 ubiquitin E3 ligase complex, leading to its proteasomal degradation. Oxidative and electrophilic stresses impair the structural integrity of Keap1-Cul3 ubiquitin E3 ligase complex resulting in the dissociation of Nrf2-Keap1 binding and nuclear accumulation of Nrf2. Studies on tissue-specific Keap1 null mutation have demonstrated the important roles of Keap1 mediated Nrf2 degradation.

Association of A1538G and C2437T single nucleotide polymorphisms in heat shock protein-70 genes with diabetic nephropathy among South Indian population.

Diabetic Nephropathy (DN) is the leading cause of end-stage renal disease, characterized by progressive albuminuria and conferring additional risk of cardiovascular disease (CVD) and mortality. The crucial role of heat-shock proteins (HSPs) on renal function in patients with DN has been well documented. The present study was aimed to understand the association of gene variants on the susceptibility of Type 2 Diabetes Mellitus (T2DM) and DN.

Pathophysiological insights of methylglyoxal induced type-2 diabetes.

Diabetes mellitus is a metabolic disorder constituting a major health problem whose prevalence has gradually increased worldwide over the past few decades. Type 2 diabetes mellitus (T2DM) remains more complex and heterogeneous and arises as a combination of insulin resistance and inadequate functional β-cell mass and comprises about 90% of all diabetic cases. Appropriate experimental animal models are essential for understanding the molecular basis, pathogenesis of complications, and the utility of therapeutic agents to abrogate this multifaceted disorder.
