title: Gene network of a phosphoglycerate mutase in muscle wasting in mice.
abstract: We previously identified the insertion of an intracisternal A-particle retrotransposons (IAPs) sequence in a gene, 9630033F20Rik, that contains domains involved in glycolysis from a mouse model called lethal wasting (lew). However, because both IAP insertion and the muation of vesicle-associated membrane protein 1 (VAMP1) were discovered from lew, the impact of the IAP insertion and Vamp1 on the lew mouse phenotype needs further investigation. In this study, the effect of the 9630033F20Rik and Vamp1 on glycolysis and muscle-wasting genes in heart, muscle, and brain tissues was further investigated using data of gene expression profiles in these tissues. Our data indicated that the expression levels of 9630033F20Rik and Vamp1 are not associated with each other. While 9630033F20Rik affects the expression of several key genes in pathways of glycolysis and muscle wasting, Vamp1 affects a different set of genes, with fewer numbers. In situ hybridization indicated that the expression of 9630033F20Rik is different in musculoskeletal tissues between the muscle-wasting mouse model and the wild-type model. Our data indicated that 9630033F20Rik may play an important role in muscle wasting and that it has a distinguished characterization of gene network. Our data also suggest that both 9630033F20Rik and Vamp1 play functional roles in muscle development and lead to the muscle-wasting phenotype when they are mutated.
