Mechano-growth factor, an IGF-I splice variant, rescues motoneurons and improves muscle function in SOD1(G93A) mice.
281 - 289.
Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder characterized by motoneuron degeneration. Although viral delivery of IGF-I has shown therapeutic efficacy in the SOD1(G93A) mouse model of ALS, clinical trials of IGF-I in ALS patients have led to conflicting results. Here we examine the effects of an IGF-I splice variant, mechano-growth factor (MGF) which has previously been shown to have greater neuroprotective effects than IGF-I in a number of models of neurodegeneration. A mammalian expression plasmid containing either MGF or, for comparison, the IGF-I cDNA sequence was delivered to the hindlimb muscles of SOD1(G93A) mice at 70 days of age, at symptom onset. Treatment with either IGF-I or MGF resulted in a significant improvement in hindlimb muscle strength, and an increase in motor unit and motoneuron Survival. Significantly more motoneurons survived in MGF treated mice. (c) 2008 Elsevier Inc. All rights reserved.
