  • Gene Silencing Using mRNA-cDNA Hybrids
    Publication number: 20100249212
    Abstract: The present invention provides novel compositions and methods for suppressing the expression of a targeted gene using mRNA-cDNA duplexes. The invention further provides novel methods and compositions for generating amplified mRNA-cDNA hybrids, whose quantity is high enough to be used for the invention's gene silencing transfection. This improved RNA-polymerase chain reaction method uses thermocycling steps of promoter-linked double-stranded cDNA or RNA synthesis, in vitro transcription and then reverse transcription to amplify the amount of mRNA-cDNA hybrids up to two thousand folds within one round of the above procedure.
    Type: Application
    Filed: December 2, 2009
    Publication date: September 30, 2010
    Applicant: University of Southern California
    Inventors: Shi-Lung Lin, Cheng-Ming Chuong, Randall B. Widelitz
