Columbia research lifts major hurdle to gene therapy for cancer

switch is flipped on by PEA-3 or AP-1. When added to a mix of normal and prostrate cancer cells, the virus entered both but only produced the toxic protein inside the cancer cells. All the prostrate cancer cells died while the normal cells were unaffected. The same virus also selectively killed human cancer cells from melanoma and ovarian, breast, and glioma (brain) tumors. Dr. Fisher's team is now altering the virus and developing additional viruses based on the PEG switch for use in clinical trials with patients. Other investigators associated with the PNAS study include Drs. Zao-zhong Su (research scientist), Devanand Sarkar (associate research scientist) and Luni Emdad (postdoctoral research scientist) in Dr. Fisher's group; Drs. Gregory J. Duigou (associate research scientist) and C. S. Hamish Young (professor) in the Department of Microbiology (Columbia University Medical Center); and Dr. Joy Ware (professor), Mr. Aaron Randolph (graduate student) and Dr. Kristoffer Valerie (professor) at Virginia Commonwealth University, Richmond, VA.
