Abstract/OtherAbstract:
Glycogen storage disease type II (GSDII) is an autosomal recessive disorder caused by defects in the acid alpha-glucosidase (GAA) gene leading to lysosomal glycogen accumulation, mainly in cardiac and muscle tissues. In order to facilitate biological investigation on this disease and to avoid time-consuming direct cell isolation and culture, we have established murine myogenic GSDII cell lines. Lentiviral/retroviral expression of SV40 T antigen, Bmi-1 or cyclin-dependent kinase 4 (CDK4) genes was used to induce the immortalization of primary satellite cells from GSDII mice. The resulting immortalized myoblasts exhibit phenotypic characteristics of their parental cells, including profound GAA deficiency, glycogen accumulation and the ability to fully differentiate into myotubes when placed in proper culture conditions. These cell lines will constitute a powerful tool for both basic and applied studies focused on a better understanding of the pathophysiological mechanisms involved in GSDII and for assessing putative therapeutic strategies.
