The first three studies in Table 1 selected a limited set of miRNAs to analyze: 43 miRNAs found up-regulated in SOD1 spinal cord CD39+ microglia and splenic Ly6Chi monocytes [54], a group of TARDBP binding miRNAs [55], or one selected miRNA, over-expressed in ALS blood leucocytes [56], respectively. Here, SOD1 is linked to amyotrophic lateral sclerosis.
