Understand the human health impacts of ciguatoxin exposure.
Specific Aim 1:
Evaluate mechanisms of toxicity using in vitro models to understand the progression of ciguatera-related illness in humans
Specific Aim 2:
Examine the genotoxic and metabolic effects of ciguatoxins upon chronic vs. acute exposure
Specific Aim 3:
Understand the cellular-level impacts of secondary ciguatoxin exposure or co-exposure to other environmental genotoxins
Specific Aim 4:
Examine the chemical and biological interactions occurring within the cell in response to ciguatoxin and metabolite exposure
Research in the Sobol lab focuses on mechanisms of DNA damage and repair, ADP-ribosylation and NAD+ metabolism in human cells and the convergent role of these enzymes and pathways in response to chemotherapy, environmental genotoxins and ocean toxins. A major goal in the lab is to use biochemical, genetic and imaging modalities to study DNA repair protein complexes that respond to DNA damage induced by chemotherapy, environmental genotoxins and ocean toxins and how these pathways impact the human genome and affect the regulation of cellular metabolism via ADP-ribosylation signaling.
Research Projects:The Sobol lab works on projects involving molecular mechanisms of DNA damage and repair, mechanisms of genotoxicity and synthetic lethality mechanisms to target cancer. Student projects can be developed around any of these projects.
- Novel approaches to enhance tumor cell cytotoxicity of alkylating agents
- A systems biology approach to mapping and defining the cellular response to DNA damage
- Greater Caribbean Center for Ciguatera Research-Human mechanisms of genotoxicity and cellular metabolism
- Measuring genomic DNA damage and DNA repair capacity in longitudinal population samples - a step towards precision prevention
- Investigating genetic ancestry influences on oral cavity and laryngeal cancer survival disparities
- Discovery of chromatin factors that regulate PARP1-dependent DNA repair in human cancers
- Identification and functional analysis of DNA repair inhibitors
