However, the metabolic effects of another family member, leukemia inhibitory factor (LIF), are not well characterized.Methods: Effects of LIF on skeletal muscle glucose uptake, palmitate oxidation and signaling were investigated in ex-vivo incubated mouse soleus and EDL muscles from muscle-specific AMPKα2 kinase-dead, muscle-specific SOCS3 knockout, and lean and high-fat fed mice. Inhibitors were used to investigate involvement of specific signaling pathways.Results: LIF increased muscle glucose uptake in dose (50-5000 pM/L) and time-dependent manners with maximal effects at the 30 min time-point. LIF increased Akt Ser473-P in soleus and EDL, whereas AMPK Thr172-P was unaffected. Incubation with Parthenolide abolished LIF-induced glucose uptake and STAT3 Tyr705-P, whereas, incubation with LY-294002 and Wortmannin suppressed both basal and LIF-induced glucose uptake and Akt Ser473-P, indicating that JAK- and PI3-kinase signaling is required for LIF-stimulated glucose uptake. Incubation with Rapamycin and AZD8055 indicated that Mammalian Target of Rapamycin complex (mTORC) 2, but not mTORC1, also is required for LIF-stimulated glucose uptake. In contrast to CNTF, LIF-stimulation did not alter palmitate oxidation. LIF-stimulated glucose uptake was maintained in EDL from obese insulin resistant mice, whereas soleus developed LIF resistance.
