Because of the asymptomatic process of carcinogenesis, the early detection of cancers such as hepatocellular carcinoma (HCC) is very challenging. Tumor-prone transgenic mouse models of oncogenesis can provide a stable and powerful tool for the analysis of cancer initiation, and are therefore promising for the discovery of early putative biomarkers of HCC.

Phage display of antibody libraries is a powerful tool for antibody discov-ery and evolution. Recombinant antibodies have been displayed on phage particles as scFvs or Fabs, and more recently as bivalent F(ab¢)2.We recently developed a technology (E-clonal) for screening of combinatorial IgG libraries using bacterial periplasmic display and selection by fluores-cence-activated cell sorting (FACS) [Mazor Yet al.

Peptidomics is a powerful set of tools for the identification, structural eluci-dation and discovery of novel regulatory peptides and for monitoring the degradation pathways of structurally and catalytically important proteins. Amphibian skin secretions, arising from specialized granular glands, often contain complex peptidomes containing many components of entirely novel structure and unique site-substituted analogues of known peptide families.

RNA interference (RNAi) is a powerful tool to silence gene expression post-transcriptionally. Delivering sequences of RNAi in vivo remains a problem. The aim of this study was to use JC virus (JCV) virus-like particles (VLPs) as a vector for delivering RNAi in silencing the cytokine gene of IL-10. Methods: JCV VLPs were generated by recombinant JCV VP1 protein in yeast expression system. DNA fragment containing IL-10 shRNA was packaged into VLPs by osmotic shock. Results: In RAW 264.7 cells, IL-10 shRNA was found to reduce IL-10 expression by 85 to 89%, as compared with VLPs alone.
