Unique peptide could treat cancers, neurological disorders, and infectious diseases
Date:2/7/2013

Internal Medicine and Microbiology, is a Howard Hughes Medical Institute investigator at UT Southwestern.

Disruption of the autophagy process is implicated in a wide variety of conditions including aging, and diseases, including cancers, neurodegenerative diseases such as Parkinson's and Alzheimer's, and infectious diseases such as those caused by West Nile and HIV viruses.

UT Southwestern has applied for a patent on Tat-beclin-1. Peptides are strings of amino acids found in proteins. The Tat-beclin 1 peptide was derived from sequences in beclin 1, one of the first known proteins in mammals found to be essential for autophagy, a finding that was made by Dr. Levine's laboratory. Her research has since demonstrated that defects in beclin 1 contribute to many types of disease. Conversely, beclin 1 activity and the autophagy pathway appear to be important for protection against breast, lung, and ovarian cancers, as well as for fighting off viral and bacterial infections, and for protecting individuals from neurodegenerative diseases and aging.
