Professional Interests

The Gavathiotis laboratory's research aims to elucidate and target molecular signaling mechanisms of cell death and cell survival that are deregulated in cancer and other diseases. Our goal is to translate our mechanistic and structural insights of protein interactions into novel pharmacological strategies and chemical probes that can be used for target validation and serve as the basis for novel therapeutics. To achieve our goal, we take an interdisciplinary approach using chemical synthesis, structure-based design, structural biology (NMR and X-ray crystallography), biochemistry, cellular and in vivo pharmacology.

Molecular Mechanisms of Cell Death Regulation
Programmed cell death is a genetically controlled physiological process that rids the body of unwanted or malfunctioning cells to maintain the normal development and homeostasis of multicellular organisms. Deregulation of cell death programs leads to variety of disease conditions and understanding the molecular mechanisms that govern cell death signaling pathways is both fundamentally important and medically relevant. Our focus is the protein interaction network of the BCL-2 family of proteins and its role in regulating apoptosis, necrosis and mitochondrial dynamics. Our current work, using structural biology, biochemical, biophysical and cell biology studies, aims to elucidate the mechanisms of protein-protein interactions and post-translational modifications to define the very determinants that modulate life and death decisions in healthy and cancer cells.
Chemical Biology of Cell Death and Chaperone-Mediated Autophagy Regulation
We apply high-throughput screening, structure-based drug design and medicinal chemistry to discover small-molecule and peptide-based chemical probes that bind to proteins and modulate their function. We will use such probes to dissect signaling pathways and as templates for the development of novel therapeutics. Our targets include proteins of the mitochondrial cell death pathway and chaperone-mediated autophagy that are highly validated in in vivo models but are considered challenging or "undruggable". Recently, using structure-based drug design we identified: 1) the first small-molecule activator of pro-apoptotic BAX and demonstrated a new paradigm for pharmacologic induction of apoptosis and ii) the first class of small molecules that activate chaperone-mediated autophagy and protect cells from oxidative stress and proteotoxicity. Using drug design and medicinal chemistry for lead optimization we are currently developing these compounds as prototype therapeutics.

Molecular Mechanisms and Targeting of the MAPK/ERK Signaling Pathway
Aberrant regulation of cellular signaling pathways can lead to uncontrolled cell growth and proliferation leading to malignant transformation and tumorigenesis. Constitutive activation of the mitogen activated protein kinase (MAPK) signaling pathway is a highly frequent event in human cancer, which results from mutations in key components of the pathway or by mutations in upstream activators of the pathway. We are using chemical and structural approaches to elucidate and target novel mechanisms that regulate critical components of the MAPK signaling pathway e.g. RAS, RAF, MEK and ERK proteins. Our goals are to advance our understanding of the structure-function relationships regulating important components of the MAPK signaling pathway and provide new avenues for drug development overcoming resistance mechanisms to current therapies.
