CITED2 links hormonal signaling to PGC-1α acetylation in the regulation of gluconeogenesis.

During fasting, induction of hepatic gluconeogenesis is crucial to ensure proper energy homeostasis. Such induction is dysregulated in type 2 diabetes, resulting in the development of fasting hyperglycemia. Hormonal and nutrient regulation of metabolic adaptation during fasting is mediated predominantly by the transcriptional coactivator peroxisome proliferative activated receptor γ coactivator 1α (PGC-1α) in concert with various other transcriptional regulators.
