Researchers have developed a unique and inexpensive device which lights up malignant brain tumors.
Recurrent gliomas could have genetic profiles which are different from those of the initial tumors that spawned them, a new study reports.
Researchers discover the mTOR pathway is highly active in many cases of pediatric low-grade glioma. Blocking the pathway lead to a decreased growth of the brain tumors.
Human glioma brain tumor cell growth was halted and erased in mice, according to new research.
The RIP1 protein can either protect or destroy brain tumors, a new study suggests.
Researchers discover a way to adjust the malignancy of glioma brain cancer cells in a newly developed 3D hydrogel. The new material mimics the conditions in the brain.
A new drug could help increase the effectiveness of radiation therapy for patients with glioblastoma multiforme, the most deadly form of brain cancer. The ATM kinase inhibitor, in combination with radiation therapy, helped significantly extend survival rates in mouse models of GBM.
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 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’.
“We identified a subset of brain tumor cells that are slower growing or remain at rest, and appear to be the source of cancer recurrence after standard therapy in which the drug temozolomide is given to stop the tumor’s growth,” said Dr. Luis Parada. “Current therapy targets fast-growing tumor cells but not those responsible for new tumors. To the best of our knowledge, this is the first identification of a cancer stem-like cell in a spontaneously forming tumor inside a mammal.”
A new probe developed uses an innovative fluorescence-reading technology to help brain surgeons distinguish cancerous tissue from normal tissue. The probe tool, now already in use at the Cancer Center for brain surgery, may one day be used for surgeries for a variety of cancers.
Scientists showed in mice that disabling a gene linked to a common pediatric tumor disorder, neurofibromatosis type 1 (NF1), made stem cells from one part of the brain proliferate rapidly. But the same genetic deficit had no effect on stem cells from another brain region.
