In addition, KLF15, a member of the Krüppel‐like family of transcriptional factors, has been shown to regulate gluconeogenesis and KLF15‐deficient mice displayed severe hypoglycemia after overnight fasting 40; accordingly, 2‐day fasting induced KLF15 in two gluconeogenic organs, the liver (71st highest score) and the kidney (third highest score) (Table S2 [Sheet A and B]). The gene discussed is KLF15; the disease is Hypoglycemia.
