Evidence for macrophage-mediated suppression participating in the deficient function of splenic lymphocytes in this mouse model of insulin-dependent diabetes includes: 1) the restoration of mitogen-induced interleukin 2 production after the macrophages have been depleted by silica absorption form spleen cells; 2) the complete suppression of the cell proliferation by thioglycollate-stimulated peritoneal exudate cells from non-obese diabetic and control mice, and the partial suppression by spleen macrophages from non-obese diabetic mice; 3) the reversal of the suppression of interleukin 2 production by the prostaglandin synthetase inhibitor indomethacin (0.1-1 microgram/ml); 4) the partial suppression of interleukin 2 production, conversely, by the exogenous prostaglandins E1 and E2 (2.5 x 10(-6) mol/l).

Activation of the beta-catenin/Lef-Tcf pathway is obligate for formation of primitive endoderm by mouse F9 totipotent teratocarcinoma cells in response to retinoic acid.

|
We investigated whether the beta-catenin/Lef-Tcf-sensitive transcriptional pathway activated by Frizzled-1 plays a role in the retinoic acid-induced pathway to primitive endoderm formation.

|
The stimulation of Lef-Tcf-sensitive transcription as well as the formation of primitive endoderm was accompanied by the stabilization of beta-catenin as observed in activation of the Frizzled-1 pathway.

Transient transfection of F9 cells with an expression vector harboring a dominant-negative mutant of Tcf4 resulted in the attenuation of both the increase in Lef-Tcf-sensitive transcription and formation of primitive endoderm in response to the morphogen.
|
6 |
12063257
|
Clones stably transfected to express the dominant-negative Tcf4 displayed a block in retinoic acid-induced activation of Lef-Tcf-sensitive transcription and primitive endoderm formation.

These data reveal the obligate role of the beta-catenin/Lef-Tcf transcriptional pathway in the action of the morphogen retinoic acid.

Genes 7CF7L2 and SLC30A8, encoding transcription factor-4 and transmembrane zinc transporter-8, respectively, play an important role in the regulation of development, proliferation, and pancreatic beta cell function.

Paired-homeodomain transcription factor 4 (PAX4) functions as a transcriptional repressor and is involved in the differentiation of insulin-secreting β-cells.

Here we identified a novel PAX4 mutation in a Japanese patient with MODY.
|

|
We therefore analyzed several candidate genes of MODY, and identified a novel mutation of a 39-base heterozygous deletion in exon 3 (c.374-412 del39) of PAX4 in the proband and his father.

As expected, luciferase-reporter assays revealed that the mutant PAX4 could not repress the activities of insulin and glucagon gene promoters, unlike the wild-type PAX4 that repressed the promoter activities.
