Study data from University of Toronto update understanding of lung cancer

Published in Hospital Business Week, July 20th, 2008

According to recent research from Toronto, Canada, "New molecular cancer treatment strategies aim to reconstitute wild-type p53 (WTp53) function in mutant p53 (MTp53)-expressing tumors as a means of resensitizing cells to chemotherapy or radiotherapy. The success of this approach may depend on whether MTp53 proteins are acting in a dominant-negative or independent gain-of-function mode."

"Herein, we describe an isogenic, temperature-sensitive p53 model (p53(A138V)) in p53-null human H1299 lung cancer cells in which WTp53 can be selectively coexpressed with a temperature-sensitive MTp53 allele (A138V) during initial DNA damage and subsequent DNA repair. Cells expressing...
