Abstract:BACKGROUND: The tumor microenvironment is acidic, which inhibits the activity of weakly basic drugs such as doxorubicin. In order to test whether neutralization of tumor acidity can improve survival in pancreatic cancer-bearing mice treated with doxorubicin, we tested doxorubicin in combination with L-DOS47. L-DOS47 is a novel therapy comprised of urease conjugated to an antibody against CEACAM6, which raises the pH in the tumor microenvironment by converting endogenous urea to NH3 and CO2. Our findings demons… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
