Description of Research Expertise

Non-steroidal anti-inflammatory drugs (NSAIDs), which include both traditional NSAIDs (e.g. naproxen, ibuprofen) and NSAIDs selective for cyclooxygenase (COX)-2 (rofecoxib, valdecoxib, etoricoxib, lumiracoxib, celecoxib) relieve pain, inflammation and fever by inhibiting the formation of bioactive prostanoids. Despite their efficacy in the relief of pain and inflammation, NSAIDs may be associated with gastrointestinal complications, including serious bleeds. Selectivity for COX-2 has been shown to reduce the incidence of these serious events, but is more likely to cause serious cardiovascular events than non-selective COX inhibition.

Dr. Grosser is studying the mechanisms of these complications using genomics, proteomics, lipidomics approaches in model organisms and in proof-of-concept studies in healthy volunteers. One aim of this research is to identify approaches to the personalization of NSAID therapy.

Description of Itmat Expertise

Dr. Grosser is interested in the integration of proteomic and genomic information to probe inflammatory and anti-inflammatory pathways in humans and model systems relevant to cardiovascular pathology.
