We suggest that increased SOD1 expression can lead to tau hyperphosphorylation, which might serve as an important contributing factor to the etiology of Down syndrome and SOD1-related ALS disease.

These results highlight DS as a model to understand the role of APOE4 allele in unsuccessful ageing considering that a number of proinflammatory supernumerary genes (Cu/Zn superoxide dismutase, Ets-2 transcription factors, Down syndrome critical region 1, stress-inducible factor, interferon-alpha receptor and the amyloid precursor protein) are located on chromosome 21 and are implied in the pathologic processes of DS.

Our findings suggest that genes on the trisomic Ts1Cje segment other than APP and SOD1 can cause oxidative stress, mitochondrial dysfunction and hyperphosphorylation of tau, all of which may play critical roles in the pathogenesis of mental retardation in DS.

Down's syndrome (trisomy 21) brain tissue is considered to be susceptible to oxidative injury, mainly because its increased Cu/Zn-superoxide dismutase (SOD1) activity is not followed by an adaptive rise in hydrogen peroxide metabolizing enzymes.
