Novel Regulatory Mechanisms Of Inositol Biosynthesis In Saccharomyces Cerevisiae And Mammalian Cells, And Implications For The Mechanism Underlying Vpa-Induced Glucose 6-Phosphate Depletion, Wenxi Yu
Wayne State University Dissertations
Myo-inositol is the precursor of all inositol containing molecules, including inositol phosphates, phosphoinositides and glycosylphosphatidylinositols, which are signaling molecules involved in many critical cellular functions. Perturbation of inositol metabolism has been linked to neurological disorders. Although several widely-used anticonvulsants and mood-stabilizing drugs have been shown to exert inositol depletion effects, the mechanisms of action of the drugs and the role of inositol in these diseases are not understood. Elucidation of the molecular control of inositol synthesis will shed light on the pathologies of inositol related illnesses.
