The authors regret that the abstract of the originally published paper contains an error in the use of “increased” instead of “decreased”. The last sentence of the abstract should read: “Conclusion: We conclude that adipocyte Gαi2 is a major regulator of adipocyte lipid content in diet-induced obesity by inhibiting adipocyte lipolysis in a cAMP-dependent manner resulting in decreased energy expenditure.” The authors would like to apologise for any inconvenience caused.
