2004 OCT 6 - (NewsRx.com & NewsRx.net) -- Ras-targeted, whole yeast-based immunotherapy resulted in mutation-selective tumor remission.
"Activating mutations in Ras oncoproteins represent attractive targets for cancer immunotherapy, but few vectors capable of generating immune responses required for tumor killing without vector neutralization have been described. Whole recombinant yeast heterologously expressing mammalian mutant Ras proteins were used to immunize mice in a carcinogen-induced lung tumor model," scientists in the United States report.
"Therapeutic immunization with the whole recombinant yeast caused complete regression of established Ras mutation-bearing lung tumors in a dose-dependent, antigen-specific manner," said Yingnian Lu and colleagues at GlobeImmune Inc. and the University of Colorado. "In combination with the genomic sequencing of tumors in patients, the yeast-based ...
