A novel invention developed by a scientist from New York Institute of Technology (NYIT) could revolutionize biological and clinical research and may lead to treatments for cancer, AIDS, Alzheimer’s, diabetes, and genetic and infectious diseases. The invention allows the immobilisation of intact. double-stranded, multi-stranded or alternative DNA or RNA and has the potential to revolutionise biological and clinical research by allowing scientists to duplicate the cell environment and experiment with human, bacterial and viral genes.This patented discovery represents a leap forward from conventional DNA microarrays that use hybridization,” Since the discovery of DNA, biologists have worked to unlock the secrets of the human cell. Scientist Claude E. Gagna, Ph.D., an associate professor at NYIT’s School of Health Professions, Behavioral and Life Sciences, discovered how to immobilize intact double-stranded (ds-), multi-stranded or alternative DNA and RNA on one microarray. This immobilization allows scientists to duplicate the environment of a cell, and study, examine and experiment with human, bacterial and viral genes. This invention provides the methodology to analyze more than 150,000 non-denatured genes. The “Gagna/NYIT Multi-Stranded and Alternative DNA, RNA and Plasmid Microarray,” has been patented (#6,936,461) in the United States and is pending in Europe and Asia. Gagna’s discovery will help scientists understand how transitions in DNA structure regulate gene expression (B-DNA to Z-DNA), and how DNA-protein, and DNA-drug interactions regulate genes. The breakthrough can aid in genetic screening, clinical diagnosis, forensics, DNA synthesis-sequencing and biodefense.
