Fibroblast growth factor 1 (FGF1) is an autocrine/paracrine regulator whose binding to heparan sulphate proteoglycans effectively precludes its circulation. Although FGF1 is known as a mitogenic factor, FGF1 knockout mice develop insulin resistance when stressed by a high-fat diet, suggesting a potential role in nutrient homeostasis. Here we show that parenteral delivery of a single dose of recombinant FGF1 (rFGF1) results in potent, insulin-dependent lowering of glucose levels in diabetic mice that is dose-dependent but does not lead to hypoglycaemia. Chronic pharmacological treatment with rFGF1 increases insulin-dependent glucose uptake in skeletal muscle and suppresses the hepatic production of glucose to achieve whole-body insulin sensitization. The sustained glucose lowering and insulin sensitization attributed to rFGF1 are not accompanied by the side effects of weight gain, liver steatosis and bone loss associated with current insulin-sensitizing therapies. We also show that the glucose-lowering activity of FGF1 can be dissociated from its mitogenic activity and is mediated predominantly via FGF receptor 1 signalling. Thus we have uncovered an unexpected, neomorphic insulin-sensitizing action for exogenous non-mitogenic human FGF1 with therapeutic potential for the treatment of insulin resistance and type 2 diabetes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4184286/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉 〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4184286/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Suh, Jae Myoung -- Jonker, Johan W -- Ahmadian, Maryam -- Goetz, Regina -- Lackey, Denise -- Osborn, Olivia -- Huang, Zhifeng -- Liu, Weilin -- Yoshihara, Eiji -- van Dijk, Theo H -- Havinga, Rick -- Fan, Weiwei -- Yin, Yun-Qiang -- Yu, Ruth T -- Liddle, Christopher -- Atkins, Annette R -- Olefsky, Jerrold M -- Mohammadi, Moosa -- Downes, Michael -- Evans, Ronald M -- DE13686/DE/NIDCR NIH HHS/ -- DK-033651/DK/NIDDK NIH HHS/ -- DK-063491/DK/NIDDK NIH HHS/ -- DK-074868/DK/NIDDK NIH HHS/ -- DK057978/DK/NIDDK NIH HHS/ -- DK090962/DK/NIDDK NIH HHS/ -- ES010337/ES/NIEHS NIH HHS/ -- HL088093/HL/NHLBI NIH HHS/ -- HL105278/HL/NHLBI NIH HHS/ -- P01 DK054441/DK/NIDDK NIH HHS/ -- P01 DK074868/DK/NIDDK NIH HHS/ -- P01 HL088093/HL/NHLBI NIH HHS/ -- P01-DK054441-14A1/DK/NIDDK NIH HHS/ -- P30 DK063491/DK/NIDDK NIH HHS/ -- P42 ES010337/ES/NIEHS NIH HHS/ -- R01 HL105278/HL/NHLBI NIH HHS/ -- R24 DK090962/DK/NIDDK NIH HHS/ -- R37 DK033651/DK/NIDDK NIH HHS/ -- R37 DK057978/DK/NIDDK NIH HHS/ -- T32 DK007494/DK/NIDDK NIH HHS/ -- T32-DK-007494/DK/NIDDK NIH HHS/ -- U54 HD012303/HD/NICHD NIH HHS/ -- U54-HD-012303-25/HD/NICHD NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2014 Sep 18;513(7518):436-9. doi: 10.1038/nature13540.
