Furthermore, we found that the PGC-1alpha-mediated induction of estrogen-related receptor gamma and nuclear respiratory factor 2 (NRF-2), was dependent on the presence of ERRalpha.

The objective of this study was to further establish and confirm the relationship of adipose mitochondrial biogenesis in diabetes/obesity and the effects of rosiglitazone (RSG), a peroxisome proliferator-activated receptor (PPAR) gamma agonist, by systematically analyzing mitochondrial gene expression and function in two mouse models of obesity and type 2 diabetes.

Transcription factors, including PPAR coactivator (PGC)-1beta, PGC-1alpha, estrogen-related receptor alpha, and PPARalpha, were suppressed in both models and induced by RSG.

Estrogen-related receptor-alpha transcription factor is a key regulator of Mfn2 transcription and recruits peroxisome proliferator-activated receptor gamma coactivator (PGC)-1beta and PGC-1alpha.

|
These 2 nuclear coactivators are potent, positive regulators of Mfn2 expression in muscle cells, and ablation of PGC-1beta causes Mfn2 downregulation in skeletal muscle and in the heart.
|
169 |
19448711
|
We propose that PGC-1beta is a regulator of normal expression of Mfn2 in muscle, whereas PGC-1alpha participates in the stimulation of Mfn2 expression under a variety of conditions characterized by enhanced energy expenditure.

MFN2 and ESRRA are candidate genes involved in the pathogenesis of T2D.
|
172 |

|
Five tag-SNPs in MFN2 gene and three in ESRRA gene were selected and genotyped with TaqMan or PCR-RFLP method in stage 1 populations (555 patients with T2D and 649 control subjects) and stage 2 populations (546 patients with T2D versus 419 control subjects) in Han Chinese.

And combining our published data, we estimated the interactions between genetic variants in the MFN2, ESRRA, and PGC-1α genes on the T2D risk using MDR. rs873458 (G > A) and rs2878677 (C > T) in MFN2 gene were significantly associated with T2D (P = 0.005 and 0.01) in stage 1 populations, and the association of other SNPs with T2D was not found.

The present study also provided the evidence that MFN2 had interactions with PGC-1α (P < 0.0001) or ESRRA (P < 0.0001).
