Michael Heller,
Professor, Dept Bioengineering,
University of California-San Diego
Michael J. Heller received his PhD in Biochemistry from Colorado State University in 1973. He was an NIH Postdoctoral Fellow at Northwestern University from 1973 to 1976. From 1976 to 1984 he was supervisor of the DNA Technology Group at Amoco Corporation (Standard Oil Indiana) During that time he carried out early bioengineering and recombinant DNA work on plants, algae and photosynthetic bacteria for energy and chemical production, and developed some of the first fluorescent resonant energy transfer (FRET) and chemiluminescent oligonucleotide probes for DNA hybridization analysis. He also oversaw Amoco’s sponsored energy and chemical research work at Cetus Corporation, which included the cloning of thermophilic enzymes. Dr. Heller was the Director of Molecular Biology at Molecular Biosystems, Inc., from 1984 to 1987. He was a co-founder of Integrated DNA Technologies, and served as President and Chief Operating Officer from 1987 to 1989. He was a co-found of Nanogen and served as the Chief Technical Officer from 1993 to 2001. Nanogen carried out the successful development and commercialization of electronic DNA microarray technology for clinical diagnostic genotyping applications. Dr. Heller is a Professor (Recall/Emeritus) in the Departments of Nanoengineering and Bioengineering at the University California San Diego. He is also now a Distinguished Scientist at the Oregon Health & Science University (OHSU), Center for Cancer Early Detection and Research (CEDAR), in Portland, Oregon. He has also co-founded a company called Biological Dynamics which is developing new sample to answer cancer diagnostics technology, based on the novel dielectrophoretic (DEP) technology developed at his UCSD lab. Dr. Heller has extensive industrial experience in biotechnology, biomedical and molecular diagnostic devices and nanotechnology, with particular expertise in the areas of DNA probe diagnostics, electrokinetic lab-on-a-chip devices, DNA synthesis, FRET/fluorescent-based detection technologies and electric field assisted self-assembly of DNA nanostructures. Dr. Heller has over 100 publications and 56 issued US patents.

Multi-omic approaches using different types of biomarkers will be a viable strategy for liquid biopsy diagnostics and early cancer detection. A novel electrokinetic sample to answer device (ACE chip, Biological Dynamics, San Diego, CA) was used to isolate exosomes, extracellular vesicles (EVs) and cell free (cf) DNA from 20-50 µL of cancer patient plasma samples. Fluorescent detection of the cf-DNA and immunostaining for exosome/EV protein biomarkers could then be rapidly carried out directly on-chip. Subsequently, cf-DNA and exosome/EV entrapped RNA could be eluted from the ACE chip, whereupon PCR and sequencing analysis is conducted to identify cancer-related point mutations. Our results show correlation of immunofluorescent detection of exosome/EV glypican-1 and cf-DNA KRAS mutations (G12V, G12D) determined by digital PCR for a number of patient samples from pancreatic and colorectal cancers, where lung cancer patient samples were used as a negative control. This provides further advancement towards integrating multi-omics analysis as a single, on-chip platform, with an ultimate goal of providing seamless sample-to-answer point-of-care liquid biopsy diagnostics.
