In the heterologous cell line BHK-21, Pdx1 inhibited by 60 to 80% the activation of the alpha-cell specific element G1 conferred by Pax-6 and/or Cdx-2/3.

|
Since Pdx1 interacts directly with Pax-6 and Cdx-2/3 forming heterodimers, we suggest that Pdx1 inhibits glucagon gene transcription through protein to protein interactions with Pax-6 and Cdx-2/3.

We conclude that physiological glucose concentrations are suitable for the culturing of EBs, that the addition of FGF2 enhances the temporal expression of genes including POU5F1, nestin, FOXA2, ONECUT1, NEUROD1, PAX6, and insulin, and that EBs can be cultured in vitro for long periods, allowing for further examination of developmental processes.

We examined the association of variants in genes encoding several transcription factors (TCF1, TCF2, HNF4A, ISL1, IPF1, NEUROG3, PAX6, NKX2-2, NKX6-1, and NEUROD1) and genes encoding the ATP-sensitive K(+) channel subunits Kir6.2 (KCNJ11) and SUR1 (ABCC8) with type 2 diabetes in a Japanese cohort of 2,834 subjects.

Correspondingly, SREBP-1c DN largely corrected decreases in the expression of the transcription factors Pdx-1 and MafA but did not affect the abnormalities in Pax6, Arx, hepatic nuclear factor-1alpha (HNF1alpha), HNF3beta/Forkhead box-a2 (Foxa2), inducible cyclic AMP early repressor (ICER), or transcription factor 7-like 2 (TCF7L2) expression observed in ZDF islets.

Pax6 and Pdx1 consistently colocalized in GIP-immunoreactive cells.
|

|
GIP promoter activity was enhanced in IEC-6 cells by exogenous Pax6 or Pdx1 and diminished in STC-1 cells by inhibition of endogenous Pax6 or Pdx1 by dominant-negative forms.

|
In the HIT-T15 beta-cell line, GDNF enhanced the expression of Pax6.

|
Because MAPK can regulate Pax6, a transcription factor that controls glucagon expression, paired box gene 6 (Pax6) and glucagon gene and protein expression were also measured.
|

|
In these cells cultured, specifics MAPKs inhibitors were able to reduce both Pax6 and glucagon gene and protein expression.
|

|
In contrast, the IRS-2/MAPKs pathway is stimulated, through an activation of the IGF-IR, leading to increased Pax6 and glucagon expression.
|

|
Pax6 deficiency, as manifest in the Pax6(Sey-Neu) allele, reduced not only the number of cells expressing insulin or glucagon, but also the number of MafB, PDX-1 and MafA expressing cells.

|
Glul, Lgmn and Reg3? change the expression level of islet marker genes, where NEUROD, NKX2.2, PAX4 and PAX6 are up-regulated and somatostatin is down-regulated.
|
15 |

|
In primary rat ? cells, we confirm that Pax6 controls the transcription of the Proglucagon and processing enzyme PC2 genes and identify three new target genes coding for MafB, cMaf, and NeuroD1/Beta2, which are all critical for Glucagon gene transcription and ? cell differentiation.

|
This outcome demonstrates that the pathway for IFN-gamma regeneration requires the participation of Pax4, Pax6, and Pdx-1.
|
17 |
15180990
|
Although chromatin immunoprecipitation assays show that both Pax-6 and Pdx-1 bind to the IGRP promoter within intact cells, in contrast to the critical role of these factors in beta cell-specific insulin gene expression, IGRP gene transcription appears to require Pax-6 but not Pdx-1.
|

15561947
|
We do not however find any expression of the late-stage genes (Pax4, Pax6, Isl-1, and MafA) related to beta-cell development, and the cells do not secrete insulin upon the glucose challenge.

Cells cultured with activin A in serum-free medium upregulated expression of NeuroD and Nkx2.2 and downregulated paired box homeotic gene 6 (PAX-6).

The PDX1-transduced hepatocytes expressed several pancreatic transcription factors related to early pancreatic endocrine development (endogenous Pdx1, neurogenic differentiation factor 1 [Neurod1], and NK6 transcription factor related, locus 1 [Nkx6-1]) as well as the late-stage pancreatic transcription factors (paired box gene 4 [Pax4], paired box gene 6 [Pax6], and v-maf musculoaponeurotic fibrosarcoma oncogene homolog A [Mafa]).
|

|
Pancreatic transcription factors, PDX-1, Ngn3, NeuroD, and Isl-1, activated the INGAP promoter, but PAX4, PAX6, and Nkx2.2 did not.

In addition, to its direct role on the transcription of the glucagon gene, Pax6 controls several transcription factors involved in the activation of the glucagon gene such as cMaf, MafB and NeuroD1/Beta2 as well as different steps of glucagon biosynthesis and secretion.
