Transglutaminase 2 (TGase 2) is a Ca+2-dependent enzyme that catalyzes both intracellular and extracellular cross-linking reactions by transamidation of specific glutamine residues.

|
TGase 2 is known to be involved in the membrane-mediated events required for glucose-stimulated insulin release from the pancreatic beta cells.
|

|
Here we show that targeted disruption of TGase 2 impairs glucose-stimulated insulin secretion.

TGase 2-/- mice manifest a tendency to develop hypoglycemia after administration of exogenous insulin as a consequence of enhanced insulin receptor substrate 2 (IRS-2) phosphorylation.

Silver-Russell patients showing a broad range of ICR1 and ICR2 hypomethylation in different tissues.

|
However, several patients with transient neonatal diabetes mellitus (TNDM), Silver-Russell syndrome (SRS) and Beckwith-Wiedemann syndrome (BWS) exhibiting multilocus hypomethylation (MLH) have meanwhile been described.
|
19 |
20738330
|
Whereas TNDM patients with MLH show clinical symptoms different from carriers with isolated 6q24 aberrations, MLH carriers diagnosed as BWS or SRS present only the syndrome-specific features.
|
20 |
20738330
|
Interestingly, SRS and BWS patients with nearly identical MLH patterns in leukocytes have been identified.
|

Despite mutation screening of several factors involved in establishment and maintenance of methylation marks including ZFP57, MBD3, DNMT1 and DNMT3L the molecular clue for the ICR1/ICR2 hypomethylation in our patients remained unclear.

The imprinted 11p15 region is organized in two domains, each of them under the control of its own imprinting control region (ICR1 for the IGF2/H19 domain and ICR2 for the KCNQ1OT1/CDKN1C domain).
|
23 |

|
Disruption of 11p15 imprinting results in two fetal growth disorders with opposite phenotypes: the Beckwith-Wiedemann (BWS) and the Silver-Russell (SRS) syndromes.
|
24 |
21780245
|
Various 11p15 genetic and epigenetic defects have been demonstrated in BWS and SRS.
|
25 |
21780245
|
To investigate whether cryptic copy number variations (CNVs) involving only part of one of the two imprinted domains account for 11p15 isolated DNA methylation defects, we designed a single nucleotide polymorphism array covering the whole 11p15 imprinted region and genotyped 185 SRS or BWS cases with loss or gain of DNA methylation at either ICR1 or ICR2.
|
26 |
21780245
|
We describe herein novel small gain and loss CNVs in six BWS or SRS patients, including maternally inherited cis-duplications involving only part of one of the two imprinted domains.
|
27 |
21780245
|
We also show that ICR2 deletions do not account for BWS with ICR2 loss of methylation and that uniparental isodisomy involving only one of the two imprinted domains is not a mechanism for SRS or BWS.

Dysregulation of 11p15 genomic imprinting results in two fetal growth disorders [Silver-Russell (SRS) and Beckwith-Wiedemann (BWS) syndromes], with opposite growth phenotypes.
|
35 |

|
BWS and SRS result from abnormal imprinting involving either, both domains or only one of them, with ICR1 and ICR2 more often involved in SRS and BWS respectively.
|
36 |
22150955
|
DNA methylation defects affecting ICR1 or ICR2 account for approximately 60% of SRS and BWS patients.
|
37 |
22150955
|
Recent studies have identified new cis-acting regulatory elements, as well as new trans-acting factors involved in the regulation of 11p15 imprinting, therefore establishing new mechanisms of BWS and SRS.
|
38 |
22150955
|
Those new findings have direct consequences in molecular testing, risk assessment and genetic counseling of BWS and SRS patients.

Chromogranin A (ChgA) has been identified as the antigen target for three NOD-derived, diabetogenic CD4 T-cell clones, including the well-known BDC-2.5.
|
45 |
22912420
|
The WE14 responses of three NOD-derived CD4 T-cell clones, each with different T-cell receptors (TCRs), and of T cells from BDC-2.5 TCR transgenic mice are increased after TGase conversion of the peptide.
|
46 |
22912420
|
Primary CD4 T cells isolated from NOD mice also respond to high concentrations of WE14 and significantly lower concentrations of TGase-treated WE14.
