DOI: 10.1038/s41586-024-08224-z Memorial Sloan Kettering Cancer Center-led researchers have identified a small molecule called gliocidin that kills glioblastoma cells without damaging healthy cells, potentially offering a new therapeutic avenue for this aggressive brain tumor. ADVERTISING Glioblastoma remains one of the most lethal primary...

Circular peptides in violets may aid in the fight against glioblastoma
September 30, 2024 by Brain Chemistry Labs Wyoming violets. Credit: Dr. Paul Alan Cox, Brain Chemistry LabsGlioblastoma is one of the most serious brain diseases known. More than 45% of brain cancers are gliomas. Only half of glioblastoma patients respond to the FDA-approved chemotherapy temozolomide (TMZ). Even for those patients, the cancer cells quickly evolve...

DOI: 10.1172/JCI177384Harnessing the body’s B-cells to fight tumors may be a promising treatment for glioblastoma, according to a Northwestern Medicine study recently published in the Journal of Clinical Investigation. Glioblastoma, one of the most complex and...

Researchers discover early, promising glioblastoma treatment
by Pat Shellenbarger, Michigan State University Model depicting effects of OGM in GBM cells. Lactic acid accumulation from the Warburg effect activates GPR68, which suppresses ATF4 transcription. GPR68 inhibition by OGM induces ATF4 expression, which then increases CHAC1, leading to depletion of glutathione. This ultimately causes accumulation of toxic lipid peroxides, which triggers ferroptosis. Credit: Experimental...

Researchers design gene therapy that can effectively target glioblastoma
by Brigham and Women’s Hospital Glioblastoma (histology slide). Credit: Wikipedia/CC BY-SA 3.0Glioblastoma (GBM), an aggressive brain cancer, is notoriously resistant to treatment, with recurrent GBM associated with survival of less than 10 months. Immunotherapies, which mobilize the body’s immune defenses against a cancer, have not been effective for GBM, in part because the tumor’s surrounding environment...

Glioblastoma found to hijack cognitive neural networks with thrombospondin-1
by Justin Jackson, Medical Xpress Experimental workflow. a, Schematic of study workflow. In human participants with dominant hemisphere gliomas, we applied subcortical high density electrocorticography during audiovisual speech initiation to assess tumor intrinsic neuronal circuit dynamics. Focusing on glioblastoma, we then assessed long-range functional connectivity using magnetoencephalography (MEG) imaginary coherence. b, Extra-operative language assessments were...

DRUG CROSSES BLOOD-BRAIN BARRIER TO FIGHT GLIOBLASTOMA IN MICE
In their new study, the researchers show how a modified peptide, in mice, helps a cancer drug pass through the blood-brain barrier, which is known to be extremely difficult to penetrate and thus serves as a massive hindrance to treating brain tumors. “We were not only able to get a drug into the brain, but...

Making glioblastoma more vulnerable to treatment
by Medical College of Georgia at Augusta University Dr. Waaqo Daddacha. Credit: Michael Holahan, Augusta University In the tough war against glioblastoma, scientists are taking a cue from viruses on how to make the aggressive cancer more vulnerable to treatment. Their target is SAMHD1, a protein which can protect us from viral infections by destroying an essential...
