Biography

Beth Levine was born on April 7, 1960, in Newark, New Jersey. She grew up in New Jersey with older brothers, before graduating high school a year early. Levine died at home on June 15, 2020, from breast cancer. She is survived by her husband, Milton Packer, and children Rachel and Ben.

Columbia University Columbia University (also known as Columbia, and officially as Columbia University in the City of New York) is a private research university in New York City. Established in 1754 as King's College on the grounds of Trinity Church in Manhatt ...

from 1994 to 2004. She was recruited to become the chief of infectious diseases at the

from 2004 to 2011. She became the director of autophagy research in 2011. She served as a professor of internal medicine and microbiology at the University of Texas Southwestern Medical Center up until the time of her death. Levine created the Gordon Conference on Autophagy in Stress, Development, and Disease in 2003. Since 2008, she served as an investigator with the Howard Hughes Medical Institute. Additionally, she was elected into the American Association of Physicians and the National Academy of Sciences. In her research, Levine frequently performed cross-disciplinary experiments that opened the door to new areas for investigation. She experimented with a wide array of systems, including yeast, plant, nematode, mouse, and human. Levine discovered the first mammalian

gene, Beclin 1, and later went on to directly associate this gene with the protein

Bcl-2 Bcl-2 (B-cell lymphoma 2), encoded in humans by the ''BCL2'' gene, is the founding member of the Bcl-2 family of regulator proteins that regulate cell death (apoptosis), by either inhibiting (anti-apoptotic) or inducing (pro-apoptotic) apoptosis. ...

. This association provided significant implications in the realm of cell survival. In a 1999 paper in Nature, she proposed that autophagy was linked to tumor suppression. In 2003, she confirmed the link between Beclin 1 and tumor suppression. Additionally, Levine demonstrated links between autophagy and breast cancer. She also proved a link between autophagy and viral infections, showing how the
