Ciliary neurotrophic factor (CNTF) plays an important role in regulating neuronal growth. Recently, central anorexigenic effects of this cytokine have been characterized. However, peripheral effects on tissues that actively contribute to the regulation of energy homeostasis have not been described. Here, we report direct potent and selective effects of CNTF on growth factor and metabolic signalling intermediates in mouse brown adipocytes. CNTF stimulates STAT3, MAP kinase, Akt, and p70 S6 kinase. We find that, next to mediating Akt and p70 S6 kinase activation, both phosphatidylinositol 3-kinase and protein kinase C are separately acting, main intermediates for inducing mitogen-activated protein (MAP) kinase activation. On a functional level, CNTF enhances beta3-adrenergic induction of uncoupling protein-1. Thus, these results demonstrate direct effects of CNTF on adipose tissue signalling and metabolism and suggest a novel role for this cytokine in the peripheral regulation of energy homeostasis.
Journal of Endocrinology is committed to supporting researchers in demonstrating the impact of their articles published in the journal.
The two types of article metrics we measure are (i) more traditional full-text views and pdf downloads, and (ii) Altmetric data, which shows the wider impact of articles in a range of non-traditional sources, such as social media.
