Cyclin D1 GENE EXPRESSION INHIBITOR AND ANTICANCER DRUG

摘要

Provided are a Cyclin D1 gene expression inhibitor and an anticancer drug that gently suppress growth of cancer cells without having a cell-destroying action, and are capable of preventing the recurrence of cancer, as a novel cancer-inhibiting drug. The present invention pertains to a Cyclin D1 gene expression inhibitor including, as effective components thereof: a peptide (A) having an amino acid sequence indicated by SEQ ID NO. 1; or a peptide (B) produced by deleting, replacing, or adding at least one amino acid residue, in an amino acid sequence indicated by SEQ ID NO. 1, said peptide having a Cyclin D1 gene expression suppressing action.
