Omar Torres-Quesada, Ph.D.

Research focus

My research interest is focused in:

  1. Molecular mechanisms which operate in regulation of molecular interactions (RNA:protein, protein:protein, small-molecule:protein interactions) and their role in deregulated cell signaling pathways (i.e. cancer and neurodegenerative diseases).
  2. Profiling and targeting using kinase inhibitors of metabolic and mitochondrial functions in cancer cell models.
  3. Effect of key cellular regulators (kinases, micropeptides) on relevant human diseases (i.e. cancer and neurodegeneration).

Main areas of research: Cell Signal Transduction, Mitochondrial physiology, Drug profiling, Molecular Interactions, Cancer Molecular Biology, Cancer Physiology, Biotechnology, RNA Biology.
