Biomarker predicts bowel cancer recurrence

A biomarker in the blood of patients with bowel cancer may provide valuable insight into the risk of cancer relapse after surgery and the effectiveness of chemotherapy.

Research published in PLOS found circulating tumor DNA (ctDNA) measured before and after surgery provided a reliable marker for predicting whether the cancer would recur following chemotherapy treatment. ....

Mutant Gene-Targeted Immunotherapy Approach Developed


share:
This news release, issued by Johns Hopkins Medicine, describes a novel targeted immunotherapy approach. This new approach employs bispecific antibodies to treat cancer by eliciting a Tcell response against mutated p53. The researchers used the Highly Automated Macromolecular Crystallography (AMX) and Frontier Microfocusing Macromolecular Crystallography (FMX) beamlines to characterize the molecular structure of the proteins. AMX and FMX are beamlines at the National Synchrotron Light Source II (NSLS-II) a U.S. Department of Energy (DOE) Office of Science User Facility at Brookhaven National Laboratory. NSLS-II offers a comprehensive suite of life science research capabilities. Johns Hopkins media contacts: Amy Mone, 410-614-2915, amone@jhmi.edu, or Valerie Mehl, 410-614-2916, mehlva@jhmi.edu.

Mutant gene-targeted immunotherapy approach developed


Two of the three research studies led by Jacqueline Douglass, M.D., Ph.D. candidate at the Johns Hopkins University School of Medicine and Emily Han-Chung Hsiue, M.D., Ph.D., postdoctoral fellow at Johns Hopkins report on a precision medicine immunotherapy approach that specifically kills cancer cells by targeting mutant protein fragments presented as antigens on the cancer cell surface.
Although common across cancer types, p53 mutations have not been successfully targeted with drugs. Genetic alterations in tumor suppressor genes often resulted in their functional inactivation.
Traditional drugs are aimed at inhibiting proteins. Inhibiting an already inactivated tumor suppressor gene protein in cancer cells, therefore, is not a feasible approach, says Hsiue, lead author on the ....
