Accumulation of succinate controls activation of adipose tissue thermogenesis

Abstract

Thermogenesis by brown and beige adipose tissue, which requires activation by external stimuli, can counter metabolic disease1. Thermogenic respiration is initiated by adipocyte lipolysis through cyclic AMP–protein kinase A signalling; this pathway has been subject to longstanding clinical investigation2,3,4. Here we apply a comparative metabolomics approach and identify an independent metabolic pathway that controls acute activation of adipose tissue thermogenesis in vivo. We show that substantial and selective accumulation of the tricarboxylic acid cycle intermediate succinate is a metabolic signature of adipose tissue thermogenesis upon activation by exposure to cold. Succinate accumulation occurs independently of adrenergic signalling, and is sufficient to elevate thermogenic respiration in brown adipocytes. Selective accumulation of succinate may be driven by a capacity of brown adipocytes to sequester elevated circulating succinate. Furthermore, brown adipose tissue thermogenesis can be initiated by systemic administration of succinate in mice. Succinate from the extracellular milieu is rapidly metabolized by brown adipocytes, and its oxidation by succinate dehydrogenase is required for activation of thermogenesis. We identify a mechanism whereby succinate dehydrogenase-mediated oxidation of succinate initiates production of reactive oxygen species, and drives thermogenic respiration, whereas inhibition of succinate dehydrogenase supresses thermogenesis. Finally, we show that pharmacological elevation of circulating succinate drives UCP1-dependent thermogenesis by brown adipose tissue in vivo, which stimulates robust protection against diet-induced obesity and improves glucose tolerance. These findings reveal an unexpected mechanism for control of thermogenesis, using succinate as a systemically-derived thermogenic molecule.

Extended Data Fig. 1 Quality control for mass-spectrometry analysis of succinate in thermogenic adipose tissue.

a, Because of its unusual abundance in BAT, special consideration is required to determine the linearity of the relationship between LC–MS succinate peak intensity and succinate concentration for quantitative analysis. Succinate abundance is measured in extraction solution as described in the methods section. Absolute determination of succinate concentration is compared between succinate extracted from BAT (red) and the same samples following 100-fold dilution (green). Samples are analysed in parallel with defined amounts of [13C]succinate (black) used at concentrations that are within the established linear range of the mass spectrometer. Following 100-fold dilution of BAT extracts, succinate signals are within the linear range of detection. However, undiluted extracts are at concentrations that result in a nonlinear relationship and are therefore not appropriate for quantitative analysis. b, Calculation of the apparent dilution factor reveals the effect of nonlinearity with apparent dilutions ranging from ~11–28-fold that are in fact 100-fold.

Malonate was administered 10 min before transition to 4 °C. d, Acute oral administration of succinate by gavage drives elevation of circulating succinate (n = 4, except 10% 30 min, n = 6). e, Water consumption during high-fat feeding with or without intervention with 1% and 1.5% sodium succinate in drinking water indicates lack of aversion to succinate-containing water (vehicle, n = 35; 1%, n = 26; 1.5%, n = 18). f, Water consumption during high-fat feeding with or without intervention with 2% succinate in drinking water indicates lack of aversion to succinate-containing water (vehicle, n = 24; 2%, n = 22). g, Body weights of high-fat diet feeding mice before intervention with 1% and 1.5% sodium succinate in drinking water (vehicle, n = 35; 1%, n = 26; 1.5%, n = 18). h, Body weights of high-fat diet feeding mice before intervention with 2% sodium succinate in drinking water (vehicle, n = 24; 2%, n = 22; pair fed, n = 18). i, Caloric consumption during high-fat feeding with or without intervention with 1% or 1.5% sodium succinate in drinking water (vehicle, n = 35; 1%, n = 26; 1.5%, n = 18). j, Caloric consumption during high-fat feeding with or without 2% sodium succinate in drinking water, pair-fed mice in this experiment were fed the same number of calories as the 2% succinate group (vehicle, n = 24; 2%, n = 22; pair fed, n = 18). k, l, Caloric absorption and energy assimilation during high-fat feeding with or without 1.5% (k) or 2% (l) sodium succinate in drinking water. Proportion of energy assimilated from diet was determined by subtracting the total calories remaining in mouse faeces from the total calories consumed in the same period (n = 6). *P < 0.05, **P < 0.01; two-way ANOVA (a, b (left), c); one-way ANOVA (b (middle, right), d); two-sided t-test (k); data are mean ± s.e.m. of biologically independent samples.

af, Representative images of haematoxylin and eosin (a, b, df) or Masson’s trichrome (c) staining of indicated tissues harvested from mice following high-fat feeding with or without 4 weeks succinate supplementation in drinking water. (a, c, e top panels: 4× magnification; scale bars, 1 mm; a, c, e bottom panels, b, d, f: 40× magnification, scale bars, 50 μm). d, Cardiac morphometric analysis with or without 1.5% sodium succinate. Lower panels show representative images of cell width (40× magnification; scale bars, 50 μm). Bar charts show quantitative analysis of cardiomyocyte width and length and nuclear diameter (n = 15). g, Intraperitoneal glucose tolerance test in mice following high-fat feeding with or without 4 weeks succinate supplementation in drinking water, quantifying relative changes in glucose upon glucose challenge (n = 9). h, i, mRNA expression of inflammatory (h) and anti-inflammatory (i) markers in the indicated tissues with or without 1.5% sodium succinate in wild-type and Ucp1−/− mice (n = 3). Two-way ANOVA (g); one-way ANOVA (h); data are mean ± s.e.m. of biologically independent samples.

a, Change in body mass in Ucp1+/− (n = 9; 1.5% n = 9) and Ucp1−/− (UCP1KO, n = 7; 1.5% n = 8) male mice during high-fat feeding with or without 1.5% sodium succinate in drinking water. b, Change in body mass in Ucp1+/− (0%, n = 9; 1.5%, n = 8) and Ucp1−/− (0%, n = 6; 1.5% n = 7) female mice during high-fat feeding with or without 1.5% sodium succinate in drinking water. c, Body weights of high-fat diet feeding Ucp1+/− (vehicle, n = 18; 1.5%, n = 17) and Ucp1−/− (vehicle, n = 13; 1.5%, n = 15) mice prior to intervention with 1.5% sodium succinate in drinking water. d, Water consumption during high-fat feeding with or without intervention with 1.5% sodium succinate in drinking water in Ucp1+/− (0%, n = 18; 1.5%, n = 17) and Ucp1−/− (0%, n = 13; 1.5%, n = 15) mice indicates lack of aversion to succinate-containing water. e, Energy consumption during high-fat feeding with or without intervention with 1.5% sodium succinate in drinking water in Ucp1+/− (0%, n = 18; 1.5%, n = 17) and Ucp1−/− (0%, n = 13; 1.5%, n = 15) mice. f, Energy expenditure of Ucp1+/− and Ucp1−/− mice during 6 weeks high-fat feeding with or without 1.5% sodium succinate (Ucp1+/− 0%, n = 18; Ucp1+/− 1.5%, n = 17; Ucp1−/− 0%, n = 13; Ucp1−/− 1.5%, n = 15). Two-way ANOVA (a, b); one-way ANOVA (f); data are mean ± s.e.m. of biologically independent samples.

Reporting Summary

Supplementary Table 1

Quantification of metabolites identified by targeted LC-MS metabolomics. Relative abundance is expressed as BAT abundance relative to subcutaneous white adipose tissue abundance. Log2FC = log2 of fold change between BAT and subcutaneous abundance. Negative log10(pvalue) = negative log10 of the P value.

Supplementary Table 2

Peak ion intensity of metabolites identified by targeted LC-MS metabolomics in BAT.

Supplementary Table 3

Quantification of metabolites identified by targeted LC-MS metabolomics. Relative abundance is expressed as BAT abundance following 3 Hrs exposure of mice to 4 degrees relative to BAT from mice exposed to thermoneutrality. Log2FC = log2 of fold change between BAT from cold exposed mice versus thermoneutrality. Negative log10(pvalue) = negative log10 of the P value.
