In summary, our data suggest that allicin potentially prevents obesity and associated metabolic disorders such as type 2 diabetes mellitus by enhancing the expression of brown adipocyte-specific genes, including UCP-1, through KLF15 signal cascade.
A significant association of UCP1 polymorphisms rs1800592 [OR, 1.52 (1.10-2.08); p = 0.009] was observed in the obese cohort after adjusting with age, sex and type 2 diabetes.
A haplotype-based gene-gene interaction was observed significantly (U = -6.28, P < .001), indicating the possibility of an interaction between haplotype AAG of the PPARGC1A gene and haplotypes CTCG (odds ratio [OR] = 1.745, 95% confidence interval [95% CI] 1.069-2.847) and CTCA (OR = 0.239, 95% CI 0.060-0.958) of the UCP1 gene.Haplotype-based interaction between the PPARGC1A and UCP1 genes is associated with IFG or T2DM among residents in Henan, China.
Thermogenic genes expressions in epicardial adipose tissue (UCP1: OR 0.617, 95%CI 0.103-0.989, p=0.042; PGC1α: OR 0.416, 95%CI 0.171-0.912, p=0.031; PRDM16: OR 0.643, 95%CI 0.116-0.997, p=0.044) were showed as protective factors against the presence of heart failure with reduced left ventricular ejection fraction, and age (OR 1.643, 95%CI 1.001-3.143, p=0.026), presence of coronary artery disease (OR 6.743, 95%CI 1.932-15.301, p<0.001) and type-2-diabetes mellitus (OR 4.031, 95%CI 1.099-7.231, p<0.001) were associated as risk factors.
Although recent studies indicate that epicardial adipose tissue expresses brown fat-like genes, such as PGC1α, UCP1 and PRDM16, the association of these genes with type 2 diabetes mellitus (DM2) in coronary artery disease (CAD) remains unknown.
UCP1-3826A/G and ADRB3 Trp64Arg polymorphisms may have a combined effect in the modulation of overweight/obesity and HDL-C levels in type 2 diabetes mellitus (T2DM) Caucasian-Brazilian patients.
The association between 14 UCP (UCP2-UCP3) gene cluster tagging-SNPs and incident T2DM was investigated in 22,715 Caucasian participants of the prospective Women's Genome Health Study.
We examined the effect of 23 single nucleotide polymorphisms (SNPs) in the UCP genes on type 2 diabetes mellitus (T2DM) and related phenotypes to identify genetic factors that may be involved in susceptibility to T2DM.
