Using Viruses to Boost Mesothelioma Immunotherapy

Immunotherapy through clinical trials is becoming a promising treatment option for some mesothelioma patients. Checkpoint inhibitor drugs, such as Keytruda, already have U.S. Food and Drug Administration (FDA) approval as first-line treatments for non-small cell lung cancer (NSCLC), edging immunotherapy drugs closer to becoming a viable second-line therapy for other thoracic cancers, including pleural mesothelioma. However, overall response to immune therapies remains relatively low. Researchers across the country are striving to enhance responsiveness to immunotherapy drugs. Leading that trend is viroimmunotherapy, or the process of combining cancer-killing (oncolytic) viruses with immunotherapy drugs. Dr. Manish Patel, an assistant professor in the division of hematology, oncology and transplantation at the University of Minnesota, has studied the potential of virus therapy for mesothelioma for several years. His research led to an ongoing clinical trial at the Mayo Clinic in Rochester, Minnesota, investigating the side effects and optimal dosage levels of using a genetically altered measles virus to kill mesothelioma tumor cells. Patel and Dr. Alexander Dash of Macalester College in St. Paul, Minnesota, recently published a paper in the journal Biomedicines that analyzes measles and other oncolytic viruses as potential viroimmunotherapy treatments for pleural mesothelioma and other thoracic cancers. As research continues, Patel believes the day of using viruses to in...

The trafficking of cell surface receptors is emerging as a key step for regulating appropriate cellular responses, with perturbations in this process contributing to human diseases, including cancer. For receptors recognizing ligands of...

The objective of this study was to characterize Somali Bantu and Karen experiences with cancer and cancer screenings prior to and subsequent to resettlement in Buffalo, NY in order to inform engagement by health providers. METHODS: The study was grounded in a community-based participatory research approach, with data collection and analysis guided by the Health Belief Model and life course framework. Interviews were transcribed, independently coded by two researchers, and analyzed using an immersion-crystallization approach. We conducted 15 semi-structured interviews and six interview-focus group hybrids with Somali Ba...

This study focused on the possible role of SEC24 proteins in ATB0,+ trafficking. Rat ATB0,+ was expressed in HEK293 cells, its localization and trafficking were examined by Western blot, deglycosylation, immunofluorescence (co-localization with ER and trans-Golgi markers) and biotinylation. The expression of ATB0,+ at the plasma membrane was decreased by dominant negative mutants of SAR1, a GTPase, whose activity triggers the formation of the COPII complex. ATB0,+ co-precipitated with SEC24C (but not with the remaining isoforms A, B and D). This interaction was confirmed by immunocytochemistry and the proximity ligation as...
