STAT3 Regulation of Citrate Synthase Is Essential during the Initiation of Lymphocyte Cell Growth.

Citrate is a required carbon precursor for de novo fatty acid and membrane lipid synthesis. However, the pathways regulating intracellular citrate, particularly during the initial transition from a resting state to cell growth, remain unclear. Here, we show that STAT3 is among the first signaling events activated in resting lymphocytes following growth factor stimulation.
