At A Glance
Douglas C Wallace, PhD, is Director of the Center for Mitochondrial and Epigenomic Medicine at Children’s Hospital of Philadelphia. He holds the Michael and Charles Barnett Endowed Chair in Pediatric Mitochondrial Medicine and Metabolic Diseases. More than 35 years ago, Dr. Wallace and his colleagues founded the field of human mitochondrial genetics. The mitochondria are the cellular power plants, organelles that generate most of the cell’s energy. The mitochondria also contain their own DNA, the mitochondrial DNA (mtDNA), which encodes the wiring diagram for the cell’s power plants. Dr. Wallace showed that the mtDNA is inherited exclusively from the mother and that genetic alterations in the mtDNA can result in a wide range of metabolic and degenerative diseases as well as being important in cancer and aging.
The major challenge is the ingrained Anatomical and Mendelian paradigms on which Western Medicine is based. This concept is discussed in my article, Mitochondria as Chi” which attempts to explain why a bioenergetic paradigm shift is critical if we are to move forward in understanding the common diseases. To foster change in Medicine will require changing the perspective of Western physicians, educators, hospitals, Deans, NIH, FDA, Congress, just to mention a few. Accomplishing such a paradigm shift has proven to be extremely difficulty.
