PNDM is a genetically heterogeneous disorder due to mutations in 23 different genes described to date: KCNJ11, ABCC8, FOXP3, GCK, PDX1, pancreas-specific transcription factor 1A (PTF1A), EIF2AK3, SLC2A2
, GATA6, GATA4, SLC19A2, WFS1, NEUROD1, NEUROG3, RFX6, LRBA, NKX2-2, MNX1, IER3IP1, INS, S T A T 3 , GLIS3 and HNF1B (3,4,5,6,7,8,9).
gene is a major glucose transporter in the cattle liver .
Carbohydrate regulators affected were insulin receptor substrate 2 (Irs2), glucose-responsive fork head box O1 (Foxo1), and glucose trans- porter 2 (Slc2a2
Quantitative RT-PCR analyses of Insr and Slc2a2
genes were performed using TaqMan[TM] Fast Advanced Master Mix (Thermo Fisher Scientific 4444963) and TaqMan[R] Array Mouse Fatty Liver (Thermo Fisher Scientific 4391524, RAEPRZ3).

Brass et al .[sup] observed the amplification of genes BCHE and SLC2A2
at 3q26 in squamous cell lung carcinomas, whereas no amplification has been found in genes MME and KNG .
Compared with the blank control, mogrosides treatment showed no effect on the expression of the pyruvate kinase coding gene pklr, while palmitic acid significantly reduced expression of pklr (P<0.05; Figure 2A) and of the GLUT2 encoding gene slc2a2
in NIT-1 cells (P<0.05; Figure 2B).

An initial 25 lead SNPs were followed up in 76 558 additional study participants, and 9 new loci were found to be associated (P < 5 x [10.sup.-8]) with fasting glucose (and/or HOMA-B) [adenylate cyclase 5 (ADCY5); MAP-kinase activating death domain (MADD); cryptochrome 2 (photolyase-like) (CRY2); adrenergic, alpha-2A-, receptor (ADRA2A); fatty acid desaturase 1 (FADS1); prospero homeobox 1 (PROX1); solute carrier family 2 (facilitated glucose transporter), member 2 (SLC2A2
); GLIS family zinc finger 3 (GLIS3); and C2 calcium-dependent domain containing 4B (C2CD4B)] and 1 was found to be associated with fasting insulin and HOMA-IR concentrations [insulin-like growth factor 1 (somatomedin C) (IGF1)].
Following this, a next-generation sequencing assay was performed to analyze the coding regions and conserved splice sites of the 22 neonatal diabetes genes: KCNJ11, ABCC8, INS, EIF2AK3, FOXP3, GATA4, GATA6, GCK, GLIS3, HNF1B, IER3IP1, PDX1, PTF1A, NEUROD1, NEUROG3, NKX2-2, RFX6, SLC2A2
, SLC19A2, STAT3, WFS1, and ZFP57 (Agilent custom capture v5.1/Illumina HiSeq) at the Molecular Genetics Laboratory, University of Exeter Medical School, UK (9).
