The typical key words included “polymerase,” “experimental allergic encephalomyelitis,” “cytochrome-c,” “peroxynitrite,” “amyotrophic-lateral-sclerosis,” “tumor-necrosis-factor,” and “messenger-rna,” suggesting the studies concentrated on the apoptosis-related molecular alterations, cytokines release, and Inflammation in animal experiments in SCI. This evidence concerns the gene TNF and amyotrophic lateral sclerosis.
