Alcohol-Mediated Changes In Myoblast Hif-1Α Protein Expression And Relationships With Decreased Differentiation Capacity: A Preliminary Analysis, Colby Newman, Alexandra Khartabil, Matthew Dileo, Zenaida Villalba, Danielle Levitt
International Journal of Exercise Science: Conference Proceedings
Alcohol-mediated myopathy, or decreased functional skeletal muscle (SKM) mass, is highly prevalent among individuals with alcohol use disorder (AUD). SKM regeneration aids in maintaining functional SKM muscle mass. Using an in vitro (myoblast) model, we showed that alcohol (EtOH) treatment decreases differentiation capacity in association with decreased glycolytic function, but the underlying mechanisms are incompletely understood. Hypoxia-inducible factor (Hif)-1α is a transcription factor that promotes glycolysis, the bioenergetic pathway that primarily supports myoblast energetic demands. EtOH can increase or decrease Hif-1α expression in various cell types, but this has not been assessed in myoblasts. PURPOSE: Test the hypothesis that alcohol …
