GAPDH — MAOB
Text-mined interactions from Literome
Ou et al., Neurotox Res 2009
:
However, their mechanism of action is not clear, since the neuroprotective effect of MAO B inhibitors is associated with the blockage of
glyceraldehyde-3-phosphate dehydrogenase ( GAPDH ) -death cascade, rather than the
inhibition of
MAO B ... Over-expression of
GAPDH in cells enhances ethanol induced cell death, and also
increases the ethanol induced activation of
MAO B ... In contrast, the
MAO B inhibitors rasagiline and selegiline ( 0.25 nM ) and the rasagiline metabolite, 1-R-aminoindan ( 1 muM ) decreases the ethanol induced MAO B,
prevents nuclear translocation of
GAPDH and reduces cell death ... Furthermore, silencing TIEG2 using RNAi significantly reduces
GAPDH induced
MAO B upregulation and neurotoxicity
Ou et al., Biol Psychiatry 2010
(Alcoholism...) :
Nuclear
GAPDH interacts with the transcriptional activator, transforming growth factor-beta-inducible early gene 2 ( TIEG2 ), and
augments TIEG2 mediated
MAO B transactivation, which results in cell damage in neuronal cells exposed to EtOH ... Ethanol elicited nuclear
GAPDH augments TIEG2 mediated
MAO B , which might play a role in brain damage in subjects with alcoholism
