The global prevalence of obesity is increasing across most ages in both sexes. This is contributing to the early emergence of type 2 diabetes and its related epidemic. Having either parent obese is an independent risk factor for childhood obesity. Although the detrimental impacts of diet-induced maternal obesity on adiposity and metabolism in offspring are(More)
Lipid droplets (LDs) are important cellular organelles that govern the storage and turnover of lipids. Little is known about how the size of LDs is controlled, although LDs of diverse sizes have been observed in different tissues and under different (patho)physiological conditions. Recent studies have indicated that the size of LDs may influence(More)
Berardinelli-Seip congenital lipodystrophy type 2 (BSCL2) is the most severe form of human lipodystrophy, characterized by an almost complete loss of adipose tissue and severe insulin resistance. BSCL2 is caused by loss-of-function mutations in the BSCL2/SEIPIN gene, which is upregulated during adipogenesis and abundantly expressed in the adipose tissue.(More)
MicroRNAs are dysregulated in a setting of heart disease and have emerged as promising therapeutic targets. MicroRNA-34 family members (miR-34a, -34b, and -34c) are up-regulated in the heart in response to stress. In this study, we assessed whether inhibition of the miR-34 family using an s.c.-delivered seed-targeting 8-mer locked nucleic acid(More)
MicroRNAs (miRNAs) are short non-coding RNA molecules that are approximately 22 nucleotides in length. In the last 10 years, miRNA research and discovery has advanced at a rapid rate. This review provides a brief overview of the discovery and biology of miRNAs, and summarises some of the experimental techniques used for isolation, detection, target(More)
We previously showed that paternal high-fat diet (HFD) consumption programs β-cell dysfunction in female rat offspring, together with transcriptome alterations in islets. Here we investigated the retroperitoneal white adipose tissue (RpWAT) transcriptome using gene and pathway enrichment and pathway analysis to determine whether commonly affected network(More)
OBJECTIVE To determine whether the N363S variant in the glucocorticoid receptor (encoded by nuclear receptor subfamily 3, group C, member 1: NR3C1) is associated with obesity, type 2 diabetes, or hypertension. RESEARCH METHODS AND PROCEDURES This was a cross-sectional case-control study involving 951 Anglo-Celtic/Northern European subjects from Sydney.(More)
OBJECTIVE Myocardial infarction (MI) is a serious complication of atherosclerosis associated with increasing mortality attributable to heart failure. Activation of phosphoinositide 3-kinase [PI3K(p110 alpha)] is considered a new strategy for the treatment of heart failure. However, whether PI3K(p110 alpha) provides protection in a setting of MI is unknown,(More)
The natural polyphenol resveratrol stimulates sirtuins and extends lifespan. Here resveratrol inhibited expression of replicative senescence marker INK4a in human dermal fibroblasts, and 47 of 19,000 genes from microarray experiments were differentially expressed. These included genes for growth, cell division, cell signaling, apoptosis, and transcription.(More)
OBJECTIVE It is unclear whether the host response of gram-positive sepsis differs from gram-negative sepsis at a transcriptome level. Using microarray technology, we compared the gene-expression profiles of gram-positive sepsis and gram-negative sepsis in critically ill patients. DESIGN A prospective cross-sectional study. SETTING A 20-bed general(More)
