Osteoblast-derived intraflagellar transport 140 suppresses insulin sensitivity II

ABSTRACT: Hyperglycemia-induced damage to bone formations and function has been recognized.However, as the largest connective tissue organ, whether bone and osteocytes in turn regulate blood sugar and insulin sensitivity has not been addressed. Here we identified a novel protein termed intraflagellar transport 140 with functional importance in regulating osteogenesis, which is also related to the osteoblastic insulin sensitivity. We established Ift140 osteoblastic conditional knockout mice model, and found that blood glucose metabolism could be regulated through osteoblastic IFT140 interacting with O-GlcNAc transferase to regulate insulin signaling. The discovery provides new insight for two-way regulation between bone and glucose metabolism, and also exploring potential new target for blood glucose interventions.

Expression data from NPY Y1R-deficient osteoblastic cells

Project description:NPY signalling via osteoblastic Y1 receptors has been shown to control bone mass but also contributes significantly to the control of whole-body insulin secretion and glucose homeostasis in mice through the release of novel factor(s) which are different from the previously implicated osteocalcin. We used microarrays to identify novel endocrine factors regulated by Y1 receptors and involved in the regulation of bone mass and whole-body homeostasis.

Insulin receptor signaling in osteoblasts regulates postnatal bone acquisition and body composition

Project description:Global energy balance in mammals is controlled by the actions of circulating hormones that coordinate fuel production and utilization in metabolically active tissues. Bone-derived osteocalcin, in its undercarboxylated, hormonal form, regulates fat deposition and is a potent insulin secretagogue. Here, we show that insulin receptor (IR) signaling in osteoblasts controls osteoblast development and osteocalcin expression by suppressing the Runx2 inhibitor Twist-2. Mice lacking IR in osteoblasts have low circulating undercarboxylated osteocalcin and reduced bone acquisition due to decreased bone formation and deficient numbers of osteoblasts. With age, these mice develop marked peripheral adiposity and hyperglycemia accompanied by severe glucose intolerance and insulin resistance. The metabolic abnormalities in these mice are improved by infusion of exogenous under-carboxylated osteocalcin. These results indicate the existence of a bone-pancreas endocrine loop through which insulin signaling in the osteoblast ensures osteoblast differentiation and stimulates osteocalcin production, which in turn regulates insulin sensitivity and pancreatic insulin secretion to control glucose homeostasis. We used microarrays to detail the global gene expression changes in response to insulin acting through insulin receptor in osteoblasts and identified distinct genes specifically involved in bone remodeling process. 4 groups and 3 time points (0h as a control, 6h, 12h, and 24h)

Impact of Preoperative Oral Branched-chain Amino Acids on Reducing Postoperative Insulin Resistance.

Project description:Postoperative insulin resistance refers to the phenomenon that the body’s glucose uptake stimulated by insulin is reduced due to stress effects such as trauma or the inhibitory effect of insulin on liver glucose output is weakened after surgery. There is a clear link between postoperative insulin resistance and poor perioperative prognosis. Therefore, exploring interventions to reduce postoperative stress insulin resistance, stabilize postoperative blood glucose, and reduce postoperative complications are clinical problems that need to be solved urgently. In recent years, research on branched-chain amino acids and metabolic diseases has become a hot spot. Studies have found that in the rat model, preoperatively given a high branched-chain amino acid diet can inhibit postoperative insulin resistance and stabilize blood glucose levels. This research plan is to try to add branched-chain amino acids before surgery to observe the occurrence of postoperative insulin resistance in patients.

Effects of Hsd11b1 overexpressing in mc3T3-e1 pre-osteoblastic cell lines under glucocorticoid excess

Project description:To explore the mechanism by which osteoblastic 11β-HSD1 regulates bone formation and glucose handling, we transfected the mouse MC3T3-E1 osteoblastic cells with a plasmid carrying the exogenous Hsd11b1 or EGFP gene to construct the 11β-HSD1-overexpressed and control osteoblastic cells (hereafter MC3T3-HSD1 and MC3T3-GFP cells), respectively. After incubating with 11-DHC,we then employed RNA sequencing (RNA-seq) to examine the gene expression profile between MC3T3-HSD1 and MC3T3-GFP cells.
