Patent number: 11768205Abstract: 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.Type: GrantFiled: November 6, 2018Date of Patent: September 26, 2023Assignee: Mayo Foundation for Medical Education and ResearchInventors: Zhenkun Lou, Min Deng

Patent number: 11371099Abstract: 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.Type: GrantFiled: November 16, 2016Date of Patent: June 28, 2022Assignee: Mayo Foundation for Medical Education and ResearchInventors: Zhenkun Lou, Tongzheng Liu
