Dietary Quercetin Attenuates Adipose Tissue Expansion and Inflammation and Alters Adipocyte Morphology in a Tissue-Specific Manner.

Laura A Forney, Natalie R Lenard, Laura K Stewart, Tara M Henagan,

Chronic inflammation in adipose tissue may contribute to depot-specific adipose tissue expansion, leading to obesity and insulin resistance. Dietary supplementation with quercetin or botanical extracts containing quercetin attenuates high fat diet (HFD)-induced obesity and insulin resistance and decreases inflammation. Here, we determined the effects of quercetin and red onion extract ... Read more >>

Sudip Bajpeyi, Jeffrey D Covington, Erin M Taylor, Laura K Stewart, Jose E Galgani, Tara M Henagan,

Endurance exercise has been shown to improve lipid oxidation and increase mitochondrial content in skeletal muscle, two features that have shown dependence on increased expression of the peroxisome proliferator-activated receptor-γ coactivator 1α (PGC1α). It is also hypothesized that exercise-related alterations in PGC1α expression occur through epigenetic regulation of nucleosome positioning ... Read more >>

Tara M Henagan, Laura K Stewart, Laura A Forney, Lauren M Sparks, Neil Johannsen, Timothy S Church,

PGC1α, a transcriptional coactivator, interacts with PPARs and others to regulate skeletal muscle metabolism. PGC1α undergoes splicing to produce several mRNA variants, with the NTPGC1α variant having a similar biological function to the full length PGC1α (FLPGC1α). CVD is associated with obesity and T2D and a lower percentage of type ... Read more >>

Vitamin D status, body composition, and fitness measures in college-aged students.

Laura A Forney, Conrad P Earnest, Tara M Henagan, Loren E Johnson, Todd J Castleberry, Laura K Stewart,

Low vitamin D, commonly assessed as serum 25-hydroxyvitamin D (25OHD), is associated with the development of many age-related chronic diseases. A positive relationship exists between elevated 25OHD and muscle synthesis, strength, power, and decreased body fat in elderly individuals. However, these findings have not been consistently reported in younger healthy ... Read more >>

Melanocortin receptor expression is associated with reduced CRP in response to resistance training.

Tara M Henagan, Laura Forney, Marilyn A Dietrich, Brian R Harrell, Laura K Stewart,

The existing paradigm of exercise-induced decreases in chronic inflammation focuses on the expression of inflammatory receptors on systemic monocytes in response to exercise training, with the role of anti-inflammatory receptors largely ignored. Our recent preliminary studies indicate that the anti-inflammatory melanocortin receptors (MCRs) may play a role in modulating exercise-induced ... Read more >>

Dietary methionine restriction enhances metabolic flexibility and increases uncoupled respiration in both fed and fasted states.

Barbara E Hasek, Laura K Stewart, Tara M Henagan, Anik Boudreau, Natalie R Lenard, Corey Black, Jeho Shin, Peter Huypens, Virginia L Malloy, Eric P Plaisance, Rozlyn A Krajcik, Norman Orentreich, Thomas W Gettys,

Dietary methionine restriction (MR) is a mimetic of chronic dietary restriction (DR) in the sense that MR increases rodent longevity, but without food restriction. We report here that MR also persistently increases total energy expenditure (EE) and limits fat deposition despite increasing weight-specific food consumption. In Fischer 344 (F344) rats ...
