NCIt synonyms : Therapeutic Cancer Vaccine AST-021p;
NCIt definition : A cancer vaccine containing a peptide antigen derived from a specific protein heat
shock protein 90 (HSP90) generated by tumor cells, with potential immunostimulating
and antineoplastic activities. Upon vaccination, the HSP90 peptide vaccine may activate
the immune system to induce an immune response against HSP90-expressing tumor cells.
Hsp90, a chaperone complex protein upregulated in a variety of tumor cell types, regulates
the folding and degradation of many oncogenic signaling proteins.;
