C9orf72 and amyotrophic lateral sclerosis: The results showed that miR-142-3p was associated with (i) genes related to mitochondrial dysfunction, apoptosis, and endoplasmic reticulum stress (BCL2L1, BCL2, PIK3CG, PIK3R6, and CASP12); (ii) genes associated with glutamate excitotoxicity (CACNA1D); and (iii) ALS-related genes such as TDP43 and C9orf72.
