Today’s guest is Dr. Douglas Wallace, the director of the Center for Mitochondrial and Epigenomic Medicine at Children’s Hospital of Philadelphia.He is internationally known as the founder of mitochondrial genetics. Mitochondria are tiny structures within cells that produce 90 percent of a person’s energy and play an essential role in health and disease.Dr. Wallace’s groundbreaking research in the 1970s defined the genetics of DNA within the mitochondria, as distinct from DNA in a cell’s nucleus. His research has shown that mitochondrial DNA is inherited exclusively from the mother and that genetic alterations in the mitochondrial DNA can result in a wide range of metabolic and degenerative diseases.One of Dr. Wallace’s seminal contributions has been to use a mitochondrial DNA variation to reconstruct human origins and the ancient migrations of women. These studies revealed that humans arose in Africa approximately 200,000 years ago, and that women as well as men left Africa about 65,000 years ago to colonize Eurasia.Dr. Wallace was inducted last year into the Italian Academy of Sciences during the academy’s 234th annual meeting in Rome. Founded in 1782, membership in the academy is limited to 40 Italian scientists and 25 foreign members. Over the years, the academy has seen such notable members as Albert Einstein, Benjamin Franklin, Louis Pasteur and Rita Levi-Montalcini.Links:Dr. Wallace’s Children’s Hospital of Philadelphia bio:https://www.chop.edu/doctors/wallace-douglas-c Mitochondrial DNA Variation in Human Radiation and DiseaseWallace Cell Perspective 9-26-15 Mitochondrial DNA Mutation Associated with Leber’s Hereditary Optic NeuropathyWallace LHON 11778 Science 1988 A Mitochondrial Bioenergetic Etiology of DiseaseWallace JCI Wallace JAMA Psychiatry2017 Association Between Mitochondrial DNA Haplogroup Variation and Autism DisordersChalkia_jamapsychiatry_2017 Maternal Inheritance of Human Mitochondrial DNAGiles Maternal Inheritance 1980Show notes:
