Model of the potentil consequences nd cuses of elevted levels in the neurodegenerting rin., Neurotoxic insults re known to cutely constrin synptic functions, which in turn, cn led to more chronic cognitive dysfunctions. Here, we propose tht neurotoxic insults cn directly led to cognitive dysfunctions y epigeneticlly silencing neuroplsticity genes vi the mechnisms descried elow., Upon neurotoxic insults such s extrcellulr Aβ-firils, H2O2, intrcellulr ccumultion of p25 nd/or other stimuli, GR1 ecomes phosphorylted on S211, mrk for its ctivtion. Phoshorylted GR1 inds to its responsive element (GR responsive element, GRE) in the proximl Hdc2 promoter region in the neurodegenerting mouse rin, nd stimultes the expression of Hdc2. In the presence of Aβ-firils nd H2O2, this stimultion is further potentited, ut olished when S211 is mutted to A211 (not shown). Elevted protein levels ind to the promoter region of lerning, memory nd synptic plsticity-relted genes such s BdnfIV, synptophysin nd others. There, inding co-occurs with reduced histone cetyltion, nd thus more compcted chromtin, preventing RNA polymerse from inding (not shown), supposedly the driving force ehind the reduced gene expression oserved. Such decresed expression of neuroplsticity genes is correlted with reduced synptic plsticity nd poor memory performnce in mice with neurodegenertion. WWW.NATURE.COM/NATURE 1
