Improved in vitro human tumor models for cancer gene therapy.

Developing effective anticancer treatments is a particular challenge, as agents must contend with not only the target cellular biology, but also with the complex tumor microenvironment. Here we discuss various in vitro strategies that have sought to address this issue, with a particular focus on new methodologies that utilize clinical samples in basic research and their application in gene therapy and virotherapy.

The characterization of monoclonal antibodies to human metapneumovirus and the detection of multiple forms of the virus nucleoprotein and phosphoprotein.

Little is known of the proteome of human metapneumovirus (HMPV). In this study a panel of monoclonal antibodies to the virus have been characterized and used to identify viral proteins present in infected cell lysates. Of thirteen anti-HMPV monoclonal antibodies four reacted with recombinant fusion glycoprotein and one with recombinant G glycoprotein by immunofuorescence but not in western blots suggesting that they recognize conformation dependent epitopes.
