OGDH and Alzheimer disease: The latter reflects partial relief by l‐NAME of inhibition from S‐nitrosylation at the level of αKGDH since AD‐hiN were shown to manifest increased S‐nitrosylation of αKGDH subunit 1 and its E3 subunit DLD (Figure 1C,D), similar to that found in AD brains (Figure 1A and Table S1, Supporting Information, EXCEL spreadsheet 5, labeled “Unique to AD”).
