Title: Translational approach to detect biomarkers bedside


Biography: Srinivas Pentyala


Biomarkers are important tools for disease detection and monitoring. A highly effective, clinically useful biomarker for a specific disease should be measurable in a readily accessible body fluid, such as serum, urine or saliva. Translational approach based applications are now being widely utilized in the field of point-of-care diagnostics. The search for biomarkers in early disease detection has included proteins, metabolites and other biological molecules that are altered and secreted as a consequence of the disease process and are shed into body fluids. After collecting these body fluids, the next step was to isolate and identify the marker that would give an indication of the disease process. Unfortunately, this approach is laborious and timeconsuming, as specific candidate biomarker (s) must be identified from among the thousands of intact and altered molecules in the collected body fluids. In many disease manifestations, a marker can occur in trace amounts, yet large volumes of fluids are collected. Dipsticks and lateral flow devices that are availabale at present are limited for their ability to detect markers beyond a specific concentration and also the collection and application of sample to these existing diagnostic strips and devices have many limitations. We identified unique biomarkers for cerebrospinal fluid leaks, prostate cancer, diabetic nephropathy and other diseases and symptoms. We also designed and tested several point-of-care diagnostic detection methods and devices that can detect trace biomarkers in large volumes of samples. The translational approach to identify biomarkers and develop pointof care diagnostic methods and devices will be presented.
