The aim of the study was to investigate whether interaction of high-fructose diet and chronic stress alter insulin and glucocorticoid signalling thus affecting hepatic glucose homeostasis. High-fructose diet led to hyperinsulinemia, increased glucose transporter 2 level, elevated protein kinase B (Akt) phosphorylation, increased glucokinase mRNA and phospho-to-total glycogen synthase kinase 3 ratio and decreased expression of gluconeogenic genes. Fructose diet also led to stimulated glucocorticoid prereceptor metabolism, but downstream signalling remained unchanged due to increased glucocorticoid clearance. Stress did not affect hepatic insulin and glucocorticoid signalling nor glucose metabolism, while the interaction of the factors was observed only for glucokinase expression. The results suggest that, under conditions of fructose-induced hyperinsulinemia, suppression of gluconeogenesis and glycogen synthase activation contribute to the maintenance of glucose homeostasis. The increased glucocorticoid inactivation may represent an adaptive mechanism to prevent hyperglycaemia.Osteoporosis is now a worldwide public health problem that seriously endangers human health, but its causes have not yet been fully clarified. Recently, increasing evidence suggested that polymorphisms in CYP19A1 gene were associated with osteoporosis risk and bone mineral density (BMD), but results remained conflicting. We herein performed a meta-analysis based on evidence currently available from the literature to make a more precise estimation of these relationships. The PubMed, Embase, Cochrane library, CNKI (China National Knowledge Infrastructure), and Wan Fang databases were searched for eligible studies. Odds ratio (OR), mean difference (MD), and 95% confidenc
