Cancer Gene Therapy
Researchers from University of Bern describe findings in cancer gene therapy
October 28th, 2008
According to recent research published in the journal Cancer Gene Therapy, "Overexpression of the transcription factor E2F-1 induces apoptosis in tumor cells. This apoptotic effect is partly mediated through the induction of the double-stranded RNA-activated protein kinase (PKR)." "Here, we investigate if agents that upregulate PKR could enhance the apoptotic effect of E2F-1 overexpression in liver tumors. In human hepatocellular carcinoma (HCC) cells (Hep3B, HepG2, Huh7), adenovirus-mediated overexpression of E2F-1 (AdCMV-E2F) transcriptionally increased PKR mRNA. The subsequent increase of total and phosphorylated PKR protein was followed by induction of...
