Genetic information | Prkaa2 (or AMPK alpha2) genomic clones were isolated from a mouse 129 strain genomic library (Stratagene). The targeting construct was generated by flanking exon C, which encodes the AMPK alpha2 catalytic domain (corresponding to amino acids 189-260), with cre recombinase-specific loxP sites and inserting a PGK promoter-driven neomycin selection cassette flanked by an additional loxP site. The targeting construct was linearized and electroporated into 129/Sv MPI-I embryonic stem cells. Targeted clones were identified by Southern blot analysis of HindIII digested DNA, using a flanking 5' DNA fragment as a hybridization probe, and genotyping analysis. Cells expanded from targeted clones were injected into C57BL/6 blastocysts, and germline-transmitting chimeric animals were mated with C57BL/6 mice. The resulting heterozygous offspring were bred with EIIa-cre recombinase-expressing transgenic deleter mice to produce AMPKalpha2 (+/-) mice. |
Phenotypic information | AMPKalpha2 (-/-) mice presented high glucose levels in the fed period and during an oral glucose challenge associated with low insulin plasma levels. However, in isolated AMPKalpha2 (-/-) pancreatic islets, glucose- and L-arginine-stimulated insulin secretion were not affected. AMPKalpha2 (-/-) mice have reduced insulin-stimulated whole-body glucose utilization and muscle glycogen synthesis rates assessed in vivo by the hyperinsulinemic euglycemic clamp technique. We found an increased daily urinary catecholamine excretion in AMPKalpha2 (-/-) mice, suggesting altered function of the autonomic nervous system that could explain both the impaired insulin secretion and insulin sensitivity observed in vivo. |
Breeding history | AMPKalpha2(+/-) mice were backcrossed 9 times to C57BL/6J background at the CDTA germ-free animal house in Orleans. |
