question:
Context: PTH stimulates bone formation in Fgfr3 knockout mice through promotion of proliferation and differentiation in osteoblasts.', 'Previous studies showed that endogenous fibroblast growth factor 2 (FGF-2) is required for parathyroid hormone (PTH)-stimulated bone anabolic effects, however, the exact mechanisms by which PTH stimulate bone formation and the function of FGF receptors in mediating these actions are not fully defined. FGF receptor 3 (FGFR3) has been characterized as an important regulator of bone metabolism and is confirmed to cross-talk with PTH/PTHrP signal in cartilage and bone development.', 'Fgfr3 knockout and wild-type mice at 2-month-old and 4-month-old were intraperitoneally injected with PTH intermittently for 4 weeks and then the skeletal responses to PTH were assessed by dual energy X-ray absorptiometry (DEXA), micro-computed tomography (μCT) and bone histomorphometry.', 'Intermittent PTH treatment improved bone mineral density (BMD) and femoral mechanical properties in both Fgfr3 (-/-) and wild-type mice. Histomorphometric analysis showed that bone formation and bone resorption were increased in both genotypes following PTH treatment. PTH treatment increased trabecular bone volume (BV/TV) in WT and Fgfr3-deficient mice. The anabolic response in Fgfr3-deficient and wild-type bone is characterized by an increase of both bone formation and resorption-related genes following PTH treatment. In addition, we found that Fgfr3 null osteoblasts (compared to wild-type controls) maintained normal abilities to response to PTH-stimulated increase of proliferation, differentiation, expression of osteoblastic marker genes (Cbfa1, Osteopontin and Osteocalcin), and phosphorylation of Erk1/2.
Answer: Bone anabolic effects of PTH were not impaired by the absence of FGFR3, suggesting that the FGFR3 signaling may not be required for osteoanabolic effects of PTH activities.
answer:
Does fibroblast Growth Factor Receptor 3 Deficiency Impair the Osteoanabolic Action of Parathyroid Hormone on Mice?


question:
Context: Chemerin has been implicated to play opposing roles, either pro-inflammatory or anti-inflammatory, in various tissue inflammation processes primarily through the regulation of tissue recruitment of immune cells. However, the effect of chemerin in allergic asthma has not yet been explored. We sought to investigate the role of chemerin in the murine model of allergic asthma and explore the underlying mechanism.', 'We examined the effect of intranasal (i.n.) administration of chemerin during antigen challenge in murine models of asthma. Moreover, we examined whether administration of CCL2 or bone marrow-derived dendritic cells (BMDCs) transfer reversed the effects of chemerin on ovalbumin-induced asthma. We finally examined the effect of chemerin on CCL2 expression in activated lung epithelial cells in vitro.', 'The administration of chemerin attenuated allergic airway inflammation and airway hyperreactivity during antigen challenge. Chemerin treatment caused significant decreases in BALF CD4(+) T-cell accumulation and mRNA expression of Th2-attracting chemokines, CCL17 and CCL22, which was accompanied by significantly decreased BALF CD11c(+) CD11b(+) inflammatory DC accumulation and CCL2 production. Furthermore, airway administration of exogenous CCL2 or adoptive transfer of CD11c(+) CD11b(+) BMDCs abrogated the suppressive effects of chemerin on allergic asthma. Finally, in vitro study showed that chemerin inhibited CCL2 secretion by low-dose LPS-stimulated lung epithelial cells, which led to decreased chemotaxis of BMDCs.
Answer: Our study demonstrates that chemerin plays a protective role in allergic asthma by suppressing airway recruitment of inflammatory CD11c(+) CD11b(+) DCs through the inhibition of CCL2 secretion by active lung epithelial cells.
answer:
Does chemerin suppress murine allergic asthma by inhibiting CCL2 production and subsequent airway recruitment of inflammatory dendritic cells?


question:
Context: To measure the serum highly sensitive C-reactive protein (hs-CRP) and adiponectin levels, assess insulin sensitivity index (SI) and acute insulin response (AIR) in normal control (NC) subjects, patients with impaired glucose tolerance (IGT) and newly diagnosed type 2 diabetes mellitus (DM), and further explore the possible correlation between hs-CRP and SI, AIR and adiponectin in IGT and newly diagnosed type 2 DM groups.', "Age and sex matched 28 normal subjects, 31 patients with IGT, and 31 patients with newly diagnosed type 2 DM were included in the study. SI and AIR were assessed by the reduced sample number of Bergman's minimal model method with intravenous glucose tolerance test in subjects of each group.", 'Compared with NC group, serum hs-CRP was significantly increased in IGT and type 2 DM groups (p < 0.001), although there was no significant difference between the latter groups. Hs-CRP was negatively correlated with high density lipoprotein cholesterol (HDL-C), SI and adiponectin levels (p < 0.05 to p < 0.001), and positively correlated with systolic blood pressure (SBP), fasting plasma glucose (FPG), BMI, waist-to-hip ratio (WHR), postprandial 2h plasma glucose (2hPG), fasting serum insulin (FINS) and postprandial serum insulin (PSI) in IGT and newly diagnosed type 2 DM groups (p < 0.05 to p < 0.001). In general multivariate regression, only adiponectin was the significantly independent determinant for serum hs-CRP (regression coefficient -1.380; 95% CI -2.062 to 0.698, p < 0.001); meanwhile, TG, SI, hs-CRP, FINS, 2hPG and WHR were significantly independent determinants for serum adiponectin concentration (p < 0.05 to p < 0.001).
Answer: Elevated serum hs-CRP may play a role in the development of insulin resistance syndrome and type 2 diabetes. This elevation is accompanied by the opposite changes of adiponectin.
answer:

Are serum CRP levels equally elevated in newly diagnosed type 2 diabetes and impaired glucose tolerance and related to adiponectin levels and insulin sensitivity?
