Research Interest: The effect of H63D HFE polymorphism on mitochondrial dysfunction in amyotrophic lateral sclerosis

Advisor: James Connor, PhD
Graduate Program: Molecular Medicine


Description:Amyotrophic lateral sclerosis (ALS, also known as Lou Gehrig's disease), is a debilitating neurodegenerative disorder affecting both upper and lower motor neurons.  Research from our lab and others has shown that approximately 30% of ALS patients with the sporadic form of ALS carry a mutation in the HFE gene, which is associated with iron overload in hemochromatosis.  Furthermore, ongoing studies suggest a role for mitochondrial dysfunction in the pathogenesis of ALS.  Changes in mitochondrial morphology, localization, calcium buffering capacity, and regulation of oxidative phosphorylation as well as mitophagy and apoptosis occur in mouse models of the disease.  Building upon these findings, my research will investigate the role of mitochondrial dysfunction in various model systems relevant to ALS.  I will study human cell lines carrying mutant HFE vectors, as well as mice with HFE, superoxide dismutase (SOD, implicated in familial ALS) or both HFE and SOD gene mutations.  Finally, I will build upon current lab collaborations with the Penn State Hershey ALS Clinic to analyze mitochondrial dysfunction as well as biomarkers correlated with clinically meaningful prognostic indicators in patients.
