The recent discovery of an association between body composition, energy intake and the fat mass and obesity-associated (FTO) gene represents a promising new therapeutic target in obesity prevention. In a well, pre-established large animal model, we investigated the regulation of FTO gene expression under conditions either leading to obesity or increased risk of obesity related disorders: i) a s...
BACKGROUND Neuronatin (NNAT) is an endoplasmic reticulum proteolipid implicated in intracellular signalling. Nnat is highly-expressed in the hypothalamus, where it is acutely regulated by nutrients and leptin. Nnat pre-mRNA is differentially spliced to create Nnat-α and -β isoforms. Genetic variation of NNAT is associated with severe obesity. Currently, little is known about the long-term regul...
Increasing adiposity predisposes to the development of the metabolic syndrome, in part, through adipose tissue dysregulation and inflammation. In addition, offspring nutrient-restricted (NR) in utero can exhibit an increased risk of early-onset insulin resistance and obesity, although the mechanisms remain unclear. We aimed to: 1) define adipose tissue ontogeny of key proinflammatory and endopl...
In Caenorhabditis elegans, several manipulations that affect nutrition slow development, reduce fecundity, and increase life span. These are viewed as dietary restriction (DR) and include culture in semidefined, nutrient-rich liquid medium that is axenic (i.e., there is no microbial food source). Here we describe convenient ways to exert DR by culture on agar plates containing axenic medium. We...
Circadian rhythms are generated by an intrinsic cellular mechanism that controls a large array of physiological and metabolic processes. There is erosion in the robustness of circadian rhythms during aging, and disruption of the clock by genetic ablation of specific genes is associated with aging-related features. Importantly, environmental conditions are thought to modulate the aging process. ...
Eating a "Western diet" high in fat and sugars is associated with accelerated development of age-related metabolic diseases such as obesity, insulin resistance, and diabetes while incidences of these diseases are decreased on a low-calorie diet. The mitochondrial NAD(+)-dependent protein deacetylase SIRT3 has previously been shown to be important in adapting to metabolic stress brought on by fa...
