NCIt definition : A peptide vaccine containing human mucin 2 (MUC2) protein conjugated with keyhole
limpet hemocyanin (KLH), with potential antineoplastic activity. MUC2, a secretory
or gel forming glycoprotein expressed predominantly in goblet cells of the gastrointestinal
and respiratory tracts, is overexpressed as an aberrant or deglycosylated form in
various tumors such as gastric carcinomas and some hormone-refractory prostate cancers.
MUC2 protein is conjugated with KLH, an immunostimulant and a hapten carrier, to enhance
immune recognition. Vaccination with MUC2-KLH may result in the production of antibodies
as well as elicit a cytotoxic T- lymphocyte (CTL) response against tumor cells expressing
MUC2.;
