  • Patent number: 11768205
    Abstract: This document provides methods and materials involved in identifying mammals (e.g., humans) having cancer cells with an elevated level of phosphorylated Ub polypeptides (e.g., an elevated level of Y59 phosphorylated Ub polypeptides). For example, methods and materials for detecting the presence of cancer cells having an elevated level of Y59 phosphorylated Ub polypeptides are provided.

  • Patent number: 11371099
    Abstract: The present invention relates to methods of using HEATR1 expression levels for guiding chemotherapy treatment of pancreatic cancer. In particular, measuring lower HEATR1 expression in pancreatic cancer is associated with resistance to the use of certain chemotherapy treatments such that by changing the treatment a better prognosis may be obtained for the patient. Further, lower HEATR1 expression is related to a poorer long-term prognosis of pancreatic cancer patients thus measuring an increase or maintenance/decrease during treatment may be useful for predicting treatment response.

  • Patent number: 11136583
    Abstract: This document provides methods and materials involved in treating cancer. For example, methods and materials for using an inhibitor of UFM1 activity or expression and/or an inhibitor of UFL1 activity or expression to reduce a cancer cell's ability to carry out a DDR, thereby increasing the sensitivity of cancer cells to treatment with a DNA damaging therapy such as radiation or chemotherapy, are provided.

  • Publication number: 20200338112
    Abstract: This document relates to methods and materials for treating cancer. For example, methods and materials for inhibiting the function of an intracellular domain of programmed death-ligand 1 (PD-L1) to sensitize cancer cells in a mammal (e.g., a human) to one or more cancer treatments (e.g., radiation therapy and/or chemotherapy) are provided. Also provided are methods and materials for identifying compounds that inhibit the function of an intracellular PD-L1 domain.

  • Publication number: 20200323860
    Abstract: This document provides methods and materials for treating cancer. For example, methods and materials for identifying a mammal as having cancer cells that express little, or no, Parkin mRNA or Parkin polypeptide and administering one or more mitotic kinase inhibitors to treat the mammal identified as having cancer cells with a Parkin deficiency are provided.
