Gene Pair Information

Gene Pair: ATF3, PDX1

Related Sentences

# PMID Sentence
1 21821004 Both thapsigargin treatment, an inducer of ER stress, and ATF3 expression decreased PDX-1 expression in pancreatic ?-cells, MIN6N8.
2 21986529 Previously, we showed that ATF3 downregulates PDX-1 gene expression in MIN6N8 pancreatic ?-cells.
3 21986529 Here, we investigated another role of ATF3 on the regulation of PDX-1 activity.
4 21986529 ATF3 significantly inhibited PDX-1-stimulated transactivation of reporter plasmid containing promoters for PDX-1 binding element and the PDX-1 target gene glucokinase, which is dependent on C-terminal domain of ATF3.
5 21986529 ATF3 interacted with PDX-1, and effectively inhibited p300-mediated transcriptional coactivation of the PBE-containing promoter, whereas C-terminal domain-deleted ATF3 did not inhibit the transcoactivation of p300.
6 21986529 Taken together, these results suggest that ATF3 inhibits PDX-1-mediated transactivation through the inhibition of p300-stimulated coactivation, which may lead to ?-cell dysfunction by ER stress.
