Abstract

The liver plays several critical roles in the metabolic adaptation to fasting. We have shown previously that the transcriptional coactivator peroxisome proliferator-activated receptor γ coactivator-1α (PGC-1α) is induced in fasted or diabetic liver and activates the entire program of gluconeogenesis. PGC-1α interacts with several nuclear receptors known to bind gluconeogenic promoters including the glucocorticoid receptor, hepatocyte nuclear factor 4α (HNF4α), and the peroxisome proliferator-activated receptors. However, the genetic requirement for any of these interactions has not been determined. Using hepatocytes from mice lacking HNF4α in the liver, we show here that PGC-1α completely loses its ability to activate key genes of gluconeogenesis such as phospho enol pyruvate carboxykinase and glucose-6-phosphatase when HNF4α is absent. It is also shown that PGC-1α can induce genes of β-oxidation and ketogenesis in hepatocytes, but these effects do not require HNF4α. Analysis of the glucose-6-phosphatase promoter indicates a key role for HNF4α-binding sites that function robustly only when HNF4α is coactivated by PGC-1α. These data illustrate the involvement of PGC-1α in several aspects of the hepatic fasting response and show that HNF4α is a critical component of PGC-1α-mediated gluconeogenesis.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
