Tumor suppressor genes, as their name implies, prevent tumors. Their failure can lead to cancer. But a study led by UC San Diego scientists demonstrated that, in one kind of glioblastoma, inhibiting a tumor suppressor gene, called DAXX actually slows down the cancer.
Glioblastoma is an unusually aggressive malignancy with a dismal 5-year survival rate. That's at least in part because these tumors employ several molecular mechanisms that suppress and evade patients' antitumor immune responses.
The research team will grow cells from various brain tumors, adding cannabidiol molecules to only some of them. They will then compare the samples through a cell staining process, which will let them see how many of the cells are dividing and how many are dying.
Having high blood sugar or diabetes is linked to a higher risk of developing most cancers. However, studies have found that brain cancers such as glioma are less common in people with diabetes and high blood sugar. Now, a new study begins to shed light on this surprising link.
There were striking immune responses to the study regimen and very striking survival times for patients with Glioblastoma. Researcher noted that the median progression-free time for the tumor to begin growing again after treatment lengthened to 25.3 months instead of the typical eight months observed in patients given the standard treatment.
University of North Carolina Lineberger Comprehensive Cancer Center researchers and collaborators have mapped genetic changes that help drive an aggressive tumor as it develops in the brain – helping to lay the foundation for targeted treatment of the disease.
Researchers have discovered that an antibody currently being evaluated in an early clinical trial against advanced adult non–central nervous system solid tumors effectively shrinks malignant masses in mouse models of different pediatric brain cancers.
In an exclusive interview with Bioscience Technology, Sredni said that after so many years in the field, she has “never felt so close” to finding a better treatment for atypical teratoid/rhabdoid tumors (AT/RT) —and the powerful gene-editing tool CRISPR/Cas9 helped her get there.
