Description of Research
Metabolic network in the visual system
The eye consumes extremely high energy every second and the disturbance of its metabolism can cause blindness. Understanding its unique metabolism is fundamental for retinal degenerative diseases like inherited degeneration, age related macular degeneration (AMD) and diabetic retinopathy.
We are addressing several questions:
- How are nutrients transported and utilized in retinal cells?
- How do photoreceptor cells,glial cells and retinal pigment epithelium coordinate together to make metabolic circuits to maintain their specialized functions?
- How important are glycolysis, mitochondrial oxidative phosphorylation and reductive carboxylation in the retina?
We are using targeted metabolomics. metabolic flux analysis and cell-specific conditional knockout mice animals to test our models.
Targeting metabolism to fight blindness
Our goal is to reveal the metabolic basis for retinal degenerative diseases and to develop new approaches to slow down or prevent blindness. We are using human primary cultured cells, patient-derived retinal cells by iPS technology, genetically modified mouse.models and collaborating with clinicians to test our hypotheses with both targeted and untargeted metabolomics, biomechanical assays and live imaging. We will develop both CRISPR and small molecule-based approaches to attack the metabolic reprogramming in retinal disease
