摘要

A polypeptide consisting essentially of the amino acid sequence NCEHFVTYCRYG (SEQ ID NO: 1), ENCEHFVNELRYG (SEQ ID NO: 3), RNCEHFVAQLRYG (SEQ ID NO: 4), NCEHFVAQLRYG (SEQ ID NO: 5), or NCEHFVTYLRYG (SEQ ID: 6), or a variant of any of the foregoing, a composition comprising same, a nucleic acid consisting essentially of a nucleotide sequence encoding the amino acid sequence of any of SEQ ID NOS: 1 - 6 or a variant thereof, a composition comprising same, a host cell comprising an above-described nucleic acid molecule, a method of inhibiting cancerous cell growth comprising contacting a collection of cancerous cells with a cell growth-inhibiting effective amount of one or more of the foregoing, a method of modulating gene expression comprising contacting a collection of cells with a gene expression-modulating effective amount of at least one above-described nucleic acid or a composition comprising same, and a method of enhancing the immune response-inducing effect of a vaccine, which method comprises adding to the vaccine at least one above-described polypeptide, or a variant thereof.
