SNX10 and amyotrophic lateral sclerosis: Taken together, these results along with the significant Pearson correlation coefficients observed in muscle biopsies suggest that Mef2c, Gsr, Col19a1, Calm1 and Snx10 may be considered potential genetic biomarkers of longevity in a mouse model of ALS (Figure 4), and the level of their expression in skeletal muscle may predict the longevity of transgenic SOD1G93A mice.
