Professional Statement
Regulation of the nitric oxide synthase (NOS) pathway using small molecules is a major strategy we employ in my laboratory to translate basic research insights into useful therapy for pulmonary diseases and cancer. Recently, we applied high throughput screening (HTS) technology to discover small molecules that directly regulate this pathway. Intriguingly, we discovered that proton pump inhibitors (PPIs; a class of FDA-approved drug developed to treat gastric acidity) directly modulate the NOS pathway and regulate many of the downstream processes associated with overly active NOS including tissue inflammation and fibrosis.More recently, we demonstrated that PPIs suppress lung inflammation and fibrosis in experimental models of lung injury in part by regulating the transcription of inducible NOS (iNOS) and several classic pro-inflammatory cytokines.
Currently, we have ongoing lung remodeling and oncology projects that leverage our strength in pharmacology:
Cancer: Our projects include protection of normal tissue from the effects of chemoradiation therapy, and selective sensitization of cancer cells to anticancer therapy.
Pulmonary: We are working towards developing stand-alone and combinatorial therapy to modulate lung inflammation and fibrosis that results from chemical (e.g. bleomycin) or ionizing radiation.
