Expansion of adult β-cell mass in response to increased metabolic demand is dependent on HNF-4α
Open accessAbstract
The failure to expand functional pancreatic β-cell mass in response to increased metabolic demand is a hallmark of type 2 diabetes. Lineage tracing studies indicate that replication of existing β-cells is the principle mechanism for β-cell expansion in adult mice. Here we demonstrate that the proliferative response of β-cells is dependent on the orphan nuclear receptor hepatocyte nuclear factor-4 α ( HNF-4 α), the gene that is mutated in Maturity-Onset Diabetes of the Young 1 (MODY1). Computational analysis of microarray expression profiles from isolated islets of mice lacking HNF-4 α in pancreatic β-cells reveals that HNF-4α regulates selected genes in the β-cell, many of which are involved in proliferation. Using a physiological model of β-cell expansion, we show that HNF-4 α is required for β-cell replication and the activation of the Ras/ERK signaling cascade in islets. This phenotype correlates with the down-regulation of suppression of tumorigenicity 5 ( ST5 ) in HNF-4 α mutants, which we identify as a novel regulator of ERK phosphorylation in β-cells and a direct transcriptional target of HNF-4α in vivo. Together, these results indicate that HNF-4α is essential for the physiological expansion of adult β-cell mass in response to increased metabolic demand.

“Our work also suggests that Mapk/Erk regulation links Pdgfr activation to Ezh2 induction and β-cell proliferation, consistent with studies demonstrating Erk regulation of Ezh2 in cancer cells33, and Erk activation that accompanies mouse β-cell expansion in pregnancy34.”

In the citing paper
“Additionally, a recent study showed that the orphan nuclear receptor hepatocyte nuclear factor-4 (HNF-4)α is required in β-cells for the proliferative response of pregnancy through activation of the Ras/ERK signaling cascade, at least in part through the regulation of the guanine nucleotide exchange factor ST5 (Figure 3) [55].”

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.
