  • Patent number: 8946173
    Abstract: The present invention provides a drug capable of causing cancer cells to restore anticancer drug sensitivity in cases in which cancer has acquired resistance to an anticancer drug and inducing cell death in cancer cells. The present invention specifically provides a cancer cell death inducing agent comprising REIC/Dkk-3 DNA as an active ingredient and having effects of potentiating an anticancer drug for cancer cells having anticancer drug resistance.
    Type: Grant
    Filed: November 5, 2008
    Date of Patent: February 3, 2015
    Assignee: Momotaro-Gene Inc.
    Inventors: Hiromi Kumon, Yasutomo Nasu, Masami Watanabe, Yuji Kashiwakura, Kensuke Kawasaki
  • Publication number: 20140056945
    Abstract: According to the present invention, a composition for inducing or activating dendritic cell-like cells so as to treat or prevent cancer by immunotherapy is provided. Specifically, the following is provided: an agent for activating cancer immunity, which comprises, as an active ingredient, the following REIC protein: (a) a protein consisting of the amino acid sequence shown in SEQ ID NO: 2; or (b) a protein consisting of an amino acid sequence derived from the amino acid sequence shown in SEQ ID NO: 2 by substitution, deletion, or addition of one or more amino acid(s) and having the activity of inducing differentiation from monocytes into dendritic cell-like cells.

  • Patent number: 8658612
    Abstract: A method for potentiating the antitumor immunity in an animal by administering REIC/Dkk-3, or a therapeutic agent for malignant mesothelioma containing REIC/Dkk-3, or a vector containing the DNA as an active ingredient; wherein the DNA consists of the nucleotide sequence shown in SEQ ID NO: 1; or (b) a DNA hybridizing under stringent conditions to the DNA consisting of a nucleotide sequence complementary to the nucleotide sequence shown in SEQ ID NO: 1 and encoding a protein having apoptosis-inducing activity and interleukin (IL-7) production-accelerating activity in cells.
