Abstract

See full text

Clostridium novyi is an obligate anaerobe that can infect hypoxic regions within experimental tumors. We found that mice bearing large, established tumors were often cured when treated with C. novyi plus a single dose of liposomal doxorubicin. The secreted factor responsible for this phenomenon was identified and, surprisingly, proved to be a member of the lipase family. The gene encoding this protein, called liposomase, has the potential to be incorporated into diverse therapeutic methods to deliver specifically a variety of chemotherapeutic agents to tumors.
