Background: Neurodevelopm.ntal abnorm.lities in fetal alcohol spectrum.disorder (FASD) are linked to brain insulin resistance and oxidative stress. However, the role of thiam.ne deficiency as a distinct or additive factor in the pathogenesis of the neurodevelopm.ntal and m.tabolic derangem.nts in FASD has not been determ.ned. m.thods: Control and ethanol-exposed hum.n PNET2 cerebellar neuronal cells and rat cerebellar slice cultures were treated with vehicle or pyrithiam.ne (Pyr) to assess independent and additive effects of thiam.ne deficiency on ethanol-m.diated neurotoxicity, m.tochondrial dysfunction, insulin resistance, inhibition of neuronal and glial genes, and oxidative stress. Results: Pyr treatm.nts (0 - 200 µm. caused dose-dependent cell loss (Crystal Violet assay) and reduced m.tochondrial function (m.T assay) in PNET2 neuronal cultures. Ethanol alone (100 m.) significantly reduced PNET2 neuronal viability, m.T activity, and ATP production. Over the broad dose range of Pyr treatm.nt, ethanol significantly reduced ATP content and cell num.er and increased m.tochondrial m.ss (m.toTracker Green). Ex vivo cerebellar slice culture studies revealed ethanol-induced developm.ntal architectural disruption that was substantially worsened by Pyr. The adverse effects of ethanol were linked to increased lipid peroxidation and inhibition of asparatyl-asparaginyl-β-hydroxylase (ASPH) expression. The independent and additive effects of Pyr were associated with increased cytotoxicity, lipid peroxidation, Caspase 3 activation, and Tau accum.lation. Conclusions: During developm.nt, alcohol exposure and thiam.ne deficiency exert distinct but overlapping m.lecular pathologies that ultim.tely im.air the structure and function of cerebellar neurons. While both insults drive cell loss and m.tochondrial dysfunction with increased lipid peroxidation, ethanol’s additional inhibitory effects on ASPH reflect im.airm.nts in insulin and IGF signaling. In contrast, Pyr’s m.in adverse e
