text: Regulation of glyceroneogenesis is a therapeutic target of type 2 diabetes treatment, specifically inhibiting it in the liver and increasing it in adipose tissues. Insulin down-regulates glyceroneogenesis in the liver, but it also suppresses it in adipose tissue. To restrict the release of free fatty acids from adipose tissues, glyceroneogenesis must be increased so they are re-esterified. Thiazolidinedione is a substance that only affects glyceroneogenesis in adipose tissue by increasing transcription of PEPC-K to up-regulate glyceroneogenesis.
