An antiserum directed against the transcription factor islet duodenum homeobox-1 (IDX-1), a regulator of pancreas development and activator of the insulin gene promoter, attenuated the binding activity of Hh-responsive protein complexes.

Both peroxisome proliferator-activated receptor-alpha (PPARalpha) and pancreatic/duodenal homeobox-1 (PDX-1) have been reported to be associated with glucose-stimulated insulin secretion (GSIS), but the relationship between PPARalpha and PDX-1 is not yet fully understood.

Furthermore, high glucose concentrations led to apoptosis of ?-cells by activation of p38MAPK and p53, and dysfunction of ?-cells through phosphatase and tensih homolog (PTEN)-dependent Jun N-terminal kinase (JNK) activation and protein kinase B (AKT/PKB) inhibition, which induced the translocation of forkhead box O1 and pancreatic duodenal homeobox-1, followed by reduced insulin expression and secretion.

The pancreatic duodenal homeobox-1 (PDX-1) expression might also be different because it links glucose metabolism to the regulation of insulin gene transcription in the pancreas. ?

Notably, three MODY genes encode transcription factors implicated in the regulation of insulin gene transcription: hepatocyte nuclear factors 1 alpha and 4 alpha, and islet duodenum homeobox-1 (IDX-1, also known as IPF-1).

Impaired functions of the transactivating factors islet duodenum homeobox-1 (IDX-1) and RIPE3b-binding proteins have been implicated in the pathological downregulation of insulin gene transcription by high glucose levels in pancreatic beta cell lines in vitro, and, similarly, the exposure of pancreatic islets to fatty acids decreases IDX-1 expression.

Islet duodenal homeobox 1 (IDX-1/PF-1/STF-1/PDX-1), a homeodomain protein that transactivates the insulin promoter, has been shown by targeted gene ablation to be required for pancreatic development.

We also demonstrated that high glucose dramatically lowered the binding activity of pancreatic duodenal homeobox 1 (the glucose-sensitive transcription factor), whereas the transcription factor rat insulin promoter element 3b1 activator was less influenced and insulin enhancer factor 1 remained unaffected.

We explored whether fetal human progenitor liver cells (FH) could be induced to differentiate into insulin-producing cells after expression of the pancreatic duodenal homeobox 1 (Pdx1) gene, which is a key regulator of pancreatic development and insulin expression in beta cells.

Induction of WT HNF1beta also inhibited the insulin secretory response to nutrient stimuli, membrane depolarisation or activation of protein kinases A and C and this correlated with a significant decrease in pancrease-duodenum homeobox-1 protein levels.

Prolonged exposure of isolated islets of Langerhans to elevated levels of fatty acids, in the presence of high glucose, impairs insulin gene expression via a transcriptional mechanism involving nuclear exclusion of pancreas-duodenum homeobox-1 (Pdx-1) and loss of MafA expression.

Pancreatic duodenal homeobox 1 (Pdx1) protein is a key transcription factor involved in the regulation of insulin gene expression that is expressed at high levels in the beta-cells of the pancreatic islets.
