Listen to a blog summary of a trending research paper published by Oncotarget in Volume 13, entitled, "Transplantation of autologous bone marrow pre-loaded ex vivo with oncolytic myxoma virus is efficacious against drug-resistant Vk*MYC mouse myeloma.“
______________________
Multiple myeloma (MM) is a currently incurable cancer of blood plasma cells. Autologous stem cell transplantation (ASCT) has had efficacious results among eligible patients. However, even after ASCT, a significant number of patients continue to relapse and become resistant to current standard therapies.
A promising new method to treat blood cancers is a form of immunotherapy called virotherapy. Oncolytic viruses are uniquely capable of being reprogrammed to selectively infect and kill various cancer cells without infecting or damaging normal cells in host organisms, including mice and humans. Researchers from Arizona State University, Emory University and the Mayo Clinic (in Scottsdale, Arizona) had previously experimented with using the oncolytic myxoma virus (MYXV) to treat MM. In nature, MYXV only affects rabbits and is innocuous in mice and humans. They found that MYXVs delivered through stem cell transplantation can eliminate some residual MM cells in the Balb/c mouse model.
“Recently, we reported that ex vivo virotherapy with oncolytic myxoma virus (MYXV) improved MM-free survival in an autologous-transplant Balb/c mouse model.”
However, the researchers found that Balb/c mice may not be ideal models for MM. They observed that the behavior of MM in Balb/c mice did not quite reflect the development, clinical manifestation and localization of MM observed in human patients. Therefore, the team conducted a new study of MYXVs in the Vk*MYC transplantable C57BL/6 mouse MM model. Their trending research paper was published in Oncotarget on March 3, 2022, and entitled, “Transplantation of autologous bone marrow pre-loaded ex vivo with oncolytic myxoma virus is efficacious against drug-resistant Vk*MYC mouse myeloma.“
