Doctor Steven Gross
Defining Signal PathwaysAt the forefront of biological nitric oxide researchIn partnership with Agilent Technologies, Dr. Steven Gross of Weill Cornell Medical College is investigating nitric oxide (NO) related diseases, therapies, and biomedical problems. NO is a critical cellular signaling molecule that impacts a variety of processes, including blood pressure, neuronal signaling, and host defense. Dr. Gross is working toward defining NO signal pathways to enable the development of therapies for related diseases, and is applying metabolomics approaches to address biomedical problems. This research is leading to the identification of novel molecular mechanisms and targets, and a greater understanding of NO synthesis and action in cells, including the effects of ancillary genes. Through the application of comprehensive mass spectrometry-based metabolomics approaches, Dr. Gross is helping researchers to better address various biomedical problems involving cell signaling, metabolism errors, and cancer and stem cell biology. The approach utilizes Agilent's Q-TOF 6500 Series Accurate-Mass Quadrupole Time-of-Flight LC/MS for high-resolution analysis over a broad range of masses. A particular application that has emerged from the work is protection against septic shock. As the leading cause of death in US ICU patients, septic shock affects 250,000–350,000 people every year and mortality estimates range from 40–60%. Dr. Gross and co-workers have shown that induction by LPS and cytokines during sepsis produces harmful quantities of NO that can lead to vasodilation, vascular collapse, and death. Various methods are now being clinically investigated to limit NO production in septic patients. For Research Use Only. Not for use in diagnostic procedures.
