Dr. Abdel Elkahloun obtained his B.Sc. from the University of Caen, and a M.Sc. and Ph.D. from the University of Rennes, France. His Ph.D. thesis was on the positional cloning, physical mapping and genetics of hemochromatosis. He completed his first post-doctoral training under Dr. Paul Meltzer at the University of Michigan for the study of sarcomas and solid tumors and then joined the National Human Genome Research Institute (NHGRI) in 1993.
At the NHGRI, Dr. Elkahloun started applying large scale screening methods to identify genes associated with osteosarcomas and was part of the team that first developed the microarray technology at the NIH. In 1996, Dr. Elkahloun joined Research Genetics, Inc., where he started a microarray department to produce the first commercially available microarrays ("GeneFilters"). In 1999, Dr. Elkahloun joined the NHGRI to start the first microarray core facility at the National Institutes of Health.
As a technology provider, the microarray core is involved in a wide range of projects looking at the characterizing of either the global expression profiles or genes sets to use as framework for diagnostics, drugs treatment and/or assays to further define the disease in question.
Most recently, Dr. Elkahloun scientific interest switched to defining exosomes or EVs (extra-cellular vesicles) in cancer. In 2014, and in collaboration with Dr. Roberts at NCI, Dr. Elkahloun demonstrated that exosomes derived from cancer cells can affect the transcriptomes of surrounding cells, specifically vascular endothelial cells through microRNAs and noncodingRNAs. Current research is aiming at defining in details the molecular mechanism behind the regulated sorting of specific RNA species in specific exosomes.
During the course of several collaborations with investigator from NIMH (National Institute of Mental Health); Dr. Kleinman (first temporal global gene expression across the human life span in normal and schizophrenic patients), Dr. Chuang (Bipolar disease) and Dr. Saavedra (Alzheimer's disease), Dr. Elkahloun gained experience the genetics of neurodegenerative and neuropsychiatric diseases. In 2015, in a cross comparative and integrative analysis of global gene expression profile, Dr. Elkahloun was able to show that Candesartan, an FDA approved drug used to treat hypertension, is in fact neuroprotective and could be used for early preventive treatment in Alzheimer's disease.
