Researchers have shown that infrared and Raman spectroscopy – coupled with statistical analysis – can be used to tell the difference between normal brain tissue and the different tumor types that may arise in this tissue, based on its individual biochemical-cell ‘fingerprint’.
New findings could provide additional insight into the cause of glioblastoma and provide new options for personalized therapeutic treatments.
Researchers report our gender can determine longevity and response to treatment for glioblastoma brain cancer. The study reports male survival is determined by genes that control cell division, where as female survival is often determine by genes that regulate the ability of cancer cells to migrate to different brain areas.
Glioblastoma can mimic the normal repair of white matter in the brain, causing the tumor to become less malignant. Additionally, a drug commonly prescribed for asthma can help suppress glioblastoma growth in mouse models.
Scientists have long believed that glioblastoma multiforme, the most aggressive type of primary brain tumor, begins in glial cells that make up supportive tissue in the brain or in neural stem cells. Researchers found that the tumors can originate from other types of differentiated cells in the nervous system, including cortical neurons.
Researchers find aspirin intake correlates with halted growth of vestibular schwannomas.
A new study reports bigger brain size could mean an increased risk of developing brain cancer. The reason, researchers say, is simple. Bigger brains have more brain cells, and thus a greater potential for cell mutations that lead to cancer.
Glioma brain tumors alter the function of astrocytes, possibly contributing to seizures many brain cancer patients experience. Astrocytes encasing gliomas exhibit different molecular signatures based on their proximity to the cancer cells. Those directly touching the cancer cells become elongated and swollen, mimicking the astrocyte's response to other epilepsy-related brain injuries.
