ABSTRACT
We have previously shown that total knockout of fibroblast growth factor-2 (FGF-2) results in prolonged survival and improved motor performance in superoxide dismutase 1 (SOD1G93A ) mutant mice, the most widely used animal model of the fatal adult onset motor neuron disease amyotrophic lateral sclerosis (ALS). Moreover, we found differential expression of growth factors in SOD1G93A mice, with distinct regulation patterns of FGF-2 in spinal cord and muscle tissue. Within the present study we aimed to characterize FGF-2-isoform specific effects on survival, motor performance as well as gene expression patterns predominantly in muscle tissue by generating double mutant SOD1G93A FGF-2 high molecular weight- and SOD1G93A FGF-2 low molecular weight-knockout mice. While isoform specific depletion was not beneficial regarding survival or motor performance of double mutant mice, we found isoform-dependent differential gene expression of epidermal growth factor (EGF) in the muscle of SOD1G93A FGF-2 low molecular weight knockout mice compared to single mutant SOD1G93A mice. This significant downregulation of EGF in the muscle tissue of double mutant SOD1G93A FGF-2 low molecular weight knockout mice implies that FGF-2 low molecular weight knockout (or the presence of the FGF-2 high molecular weight isoform) selectively impacts EGF gene expression in ALS muscle tissue.
