Clinical use of recombinant fibroblast growth factor 21 (FGF21) for the treatment of type 2 diabetes and other disorders linked to obesity has been proposed; however, its clinical development has been challenging owing to its poor pharmacokinetics. Here, we describe an alternative antidiabetic strategy using agonistic anti-FGFR1 (FGF receptor 1) antibodies (R1MAbs) that mimic the metabolic effects of FGF21. A single injection of R1MAb into obese diabetic mice induced acute and sustained ameliora ...[more]
Project description:We aimed to identify genes that are regulated by FGFR1 in brown adipose tissues of adult male ob/ob mice by injecting 1 mg/kg anti-FGFR1 agonistic antibody. Brown adipose tissues were isolated from adult male ob/ob mice at day 4 after a single intraperitoneal injection of 1 mg/kg anti-FGFR1 agonistic antibody or pair-fed mice injected with control IgG. N=6 mice per each group.
Project description:We aimed to identify genes that are regulated at downstream of FGFR1/KLB receptor complex in brown adipose tissues of adult male mice on high fat diet by injecting anti-FGFR1/KLB agonistic antibody or human FGF21. Overall design: A three condition experiment with five biological replicates per condition. Interscapular brown adipose tissues were isolated from adult male mice on high fat diet at day 5 after a single intraperitoneal injection of 10 mg/kg anti-FGFR1/KLB agonistic antibody (bFKB1) or after injection of human FGF21 at 1 mg/kg b.i.d. (2 mg/kg/day) for 5 days.
Project description:We used microarrays to detail the gene expression profile during WAT -beige transition by treatment of beta adrenergic receptor agonist . Stromal vascular fractions (SVF) from mice (n = 3/group) that received vehicle or beta3 adrenergic receptor agonist, CL, treatment were served for RNA extraction and hybridization on Affymetrix microarrays. We are trying to find out angiogenic factors genes dynamics during white adipose tissues (WAT) - beige transition.
Project description:Examination of PPARg occupancy (GSE41481) and DNA hypersensitive sites (GSE122453) in in vitro differentiatied adipocytes isolated from epididymal and inguinal white adipose tissues, as well as brown adipose tissue. Overall design: Refer to individual Series
Project description:SILAC based protein correlation profiling using size exclusion of protein complexes derived from seven Mus musculus tissues (Heart, Brain, Liver, Lung, Kidney, Skeletal Muscle, Thymus)
