UVA scientists discover possible new treatment for deadliest brain cancer

Scientists at the University of Virginia School of Medicine are chasing a new way to slow glioblastoma, the deadliest brain cancer. Their work centers on a gene called AVIL and a new drug-like molecule that shuts it down in lab tests and in mice. The research comes from Hui Li, a professor in UVA’s Department of Pathology and a scientist at the UVA Comprehensive Cancer Center. His team reports the findings in Science Translational Medicine. The group says a small molecule, called Compound A, blocks a protein made by AVIL and slows tumor growth without obvious harmful side effects in mice. Glioblastoma is a fast-growing cancer that spreads through brain tissue like tangled roots. Doctors can cut out what they can see, but the tumor often threads into healthy brain. Radiation and chemotherapy can help for a while, but not for long. A cancer with few good options If you or someone close to you has followed glioblastoma, the numbers are hard to forget. Survival averages about 15 months after diagnosis. Roughly 12,000 to 14,000 …

Silent spinal cord cells may hold the key to healing after devastating injuries and brain disease

Silent spinal cord cells may hold the key to healing after devastating injuries and brain disease

Silent cells deep in your spinal cord may hold a surprising key to healing after devastating injuries and brain disease. A new study from Cedars-Sinai, reveals that support cells called astrocytes do far more than watch from the sidelines. They help coordinate cleanup and repair across long stretches of the central nervous system, and they do it from far away. Rethinking the Role of Astrocytes Astrocytes sit throughout your brain and spinal cord, wrapping around nerve fibers and blood vessels. They help keep neurons healthy, balance chemicals and support the flow of electrical signals that let you move, feel and think. After an injury, scientists have mostly focused on astrocytes right at the damage site. Those local cells form a scar and shield nearby tissue. Joshua Burda, PhD, a neuroscientist at Cedars-Sinai, and his team took a different view. Spatiotemporal molecular decoding of SCI LRAs.
