1	12586550	HD transgenic mice develop an age-dependent reduction of insulin mRNA expression and diminished expression of key regulators of insulin gene transcription, including the pancreatic homeoprotein PDX-1, E2A proteins, and the coactivators CBP and p300.
2	15001545	PDX-1 interacts with multiple transcription factors and coregulators, including the coactivator p300, to activate the transcription of the insulin gene and other target genes within pancreatic beta-cells.
3	15001545	Several mutant PDX-1 proteins that are associated with heritable forms of diabetes in humans, in particular the mutant P63fsdelC, exhibited increased binding to a carboxy-terminal segment of p300 in the setting of decreased DNA-binding activities, suggesting that sequestration of p300 by mutant PDX-1 proteins may be an additional mechanism by which insulin gene expression is reduced in heterozygous carriers of pdx-1(ipf-1) mutations.
4	15001545	The introduction of the point mutations S66A/Y68A in the highly conserved amino-terminal PDX-1 transactivation domain reduced the ability of PDX-1 to interact with p300, substantially diminished the transcriptional activation of PDX-1, and reduced the synergistic activation of glucose-responsive insulin promoter enhancer sequences by PDX-1, E12, and E47.
5	15001545	Impairment of interactions between PDX-1 and p300 in pancreatic beta-cells may limit insulin production and lead to the development of diabetes.
6	15743769	Chromatin immunoprecipitation assays revealed that the decrease in insulin transcription was associated with decreases in the occupancies of Pdx-1 and p300 at the proximal insulin promoter.
7	21986529	In addition, chromatin immunoprecipitation analysis demonstrated that both tunicamycin treatment and ATF3 overexpression inhibited the recruitment of p300 to PDX-1 on the insulin promoter in MIN6N8 cells.
