The technique enables researchers to test hundreds of different chemical combinations on patient cells to identify promising treatment options.
Research reveals that childhood brain tumors originating from undifferentiated stem cells are more frequent and aggressive than those from oligodendrocyte precursor cells. Tumor cells from stem cells also show increased susceptibility to cancer drugs, according to a new study published in Cancer Research.
Researchers at MD Anderson Cancer Center identified a pathway by which cancer cells spread in the brain, opening up new possibilities for treatment. They found that the gene WNT5A enables glioma stem cells to transition into GdECs, leading to aggressive tumor growth and disease recurrence.
A widely used brain cancer cell line, U87MG, has been found to be of unknown origin and different from the original patient tumor. Researchers used forensic and mitochondrial DNA profiling to trace the cell line's origin, revealing a potential mix-up or cross-contamination.
Scientists at Newcastle University have made a groundbreaking discovery that brain tumour cells use fats to make energy, not sugars as previously believed. This new understanding has significant implications for developing treatments for glioma, the most common form of primary malignant brain tumour.
Researchers reveal brain cancer's highly organized structure, with glioma cells forming streams, swirls, and spheres to protect and spread tumor growth. These structures are not related to specific cancer mutations and can be targeted for treatment.
Researchers at UC Davis have discovered a molecule that interferes with the internal regulation of cancer cells, causing them to self-destruct. This mechanism was found to be effective against glioma cells, which are responsible for a usually fatal type of brain cancer, and could be applicable to other highly aggressive cancers.
Researchers are developing an irreversible electroporation technique to target and destroy therapy-resistant cells in glioblastoma. The treatment has shown success in animal trials and is now being tested on human cells.
