  • Publication number: 20160061841
    Abstract: Disclosed herein, inter alia, are methods and uses for treating a cancer in a subject. In various embodiments, a method or use includes measuring expression of nuclear factor erythroid-2 related factor 2 (NRF2), or an NRF2 target gene, in a candidate subject having cancer, or a cancer sample from the candidate subject, and determining the amount of NRF2 in the sample or in the subject having cancer, then comparing the amount of NRF2 determined, or NRF2 target gene determined, to a baseline or reference amount of NRF2 or NRF2 target gene. If the amount of NRF2 or NRF2 target gene in the sample or in the subject having cancer is less than the baseline or reference amount of NRF2 or NRF2 target gene, the subject having the cancer may be or is treated with a peptide or peptidomimetic sequence set forth herein, such as P1, P2, P3, P4, P5, P6 (SEQ ID NO:1) or P6, P5, P4, P3, P2, P1 (SEQ ID NO:2), e.g., CBP501.

  • Patent number: 9221872
    Abstract: This invention provides compounds including peptides and peptidomimetics that can be used to treat cell proliferative disorders, such as those associated with benign and malignant tumor cells. While the invention is not limited to any particular mechanism, the compounds of the invention appear to function at least in part by inhibiting G2 cell cycle checkpoint. Thus, invention compounds can be used to inhibit cell growth alone or be used in combination with a nucleic acid damaging treatment to inhibit cell growth.
