15 . A method of treating a subject suffering from a GAPDH-mediated disease, disorder, or condition comprising obtaining a biological sample comprising cells from a subject, lysing the cells, monitoring GAPDH activity in the lysed cells as a biomarker for GAPDH-mediated disease, and administering a composition comprising a GAPDH inhibitor to the subject.
16 . The method of claim 15 , wherein the cell lysates are subjected to an enzyme activity assay, changes in NAD+ concentration in the enzyme activity assay are detected, and inhibition of GAPDH by an administered GAPDH-inhibitor is monitored based on reduction of NAD+ concentration in the enzyme activity assay compared to a control solvent.
