Amyotrophic lateral sclerosis, gene deregulation in the anterior horn of the spinal cord and frontal cortex area 8: implications in frontotemporal lobar degeneration

Figure 1. (A) Total number of significantly different expressed genes comparing transcriptomic profiles between groups and regions. (B) Hierarchical clustering heat map of expression intensities of mRNA array transcripts reflect differential gene expression profiles in the anterior horn of the spinal cord and frontal cortex area 8 in ALS compared with controls. Differences between groups are considered statistically significant at p-value ≤ 0.05. Abbreviations: ALS: amyotrophic lateral sclerosis; FC: frontal cortex area 8; mRNA: messenger RNA; SP: anterior horn of the spinal cord lumbar level.
