In particular, ATP1A3, EGR1, and CHGB experience opposing deregulation in the SALS motor cortex compared to the AD hippocampus, with ANXA2, ATP6V1A, EIF4A2, NSF, and all the metallothioneins detected in the hippocampus (MT1E, MT1G, MT1X, MT2A) also showing markedly different regulation between both tissues. The gene discussed is EGR1; the disease is Alzheimer disease.
