Dagda Lab

The Dagda Lab is a mitochondrial biology-oriented research group located at the University of Nevada, Reno School of Medicine that currently spearheads basic and translational research projects supported by the NIH, philanthropic support and state funding.

These projects include:

Parkinson's disease

  • Investigate how PTEN-induced Kinase 1 (PINK1) interacts with Protein Kinase A to regulate mitochondrial function, dynamics, neuronal survival and development.
  • Investigate the pathological effects of of acute and chronic psychological stress on brain energy production, motor function and neuronal survival in Parkinson's disease rats (PINK1 knockout rats).
  • Investigate the ability of different nootropic agents to reverse neurodegeneration and motor symptoms in Parkinsonian rats.

Alzheimer's disease

  • Investigate the ability of enhancing neurotrophic and PKA activity in reversing beta amyloid aggregation and neurodegeneration in cell culture and mouse models of Alzheimer's disease.
  • Identify new biomarkers of Alzheimer's disease in fecal matter from Alzheimer's disease patients.

Amyotrophic Lateral Sclerosis

  • Investigate the pathological mechanisms by which ALS-associated mutants of TDP43 affect mitochondrial structure and mitophagy in cortical neurons.

The Dagda Lab consists of 1200 square feet of wet lab space located in Howard Medical Sciences room 148. It is equipped with high speed temperature controlled centrifuges, an EVOS-FL microscope, an EVOS-CORE microscope, a tissue culture facility, a Seahorse Biosciences XFe24 Extracellular Flux Analyzer for measuring metabolic activities of live cells, touch-screen PCR machines, a SpectraMax M4 Multimode 96 well plate reader, Western blot equipment, immunohistochemistry equipment and two 1300A2 laminar flow hoods located in the cell culture facility. The Dagda lab is located close to the Nevada Proteomics Center, the Electron Microscopy Center and the COBRE-supported confocal microscopy suite in Howard Building. The Dagda Lab supports the research projects of five undergraduate students, two doctoral students (Neuroscience, Cellular Molecular Pharmacology and Physiology, and Cell Molecular Biology programs), two postdoctoral associates, an international research scholar, and a lab manager.
