Now researchers at the School of Medicine have devised a new way to cause brain tumor tissue to stand out clearly during a type of imaging scan called positron emission tomography. (stanford.edu)
Brain tumour tissue is often stiffer than normal tissue. (oicr.on.ca)
Uncontrolled cell growth in solid tumours, such as brain tumours, causes tumour tissue to be stiffer than healthy tissue, creating an advantageous environment for tumour cells to proliferate rapidly, avoid cell death and develop resistance to drugs. (oicr.on.ca)
But how tumour tissue stiffens is not well understood. (oicr.on.ca)
A research group based at the The Hospital for Sick Children (SickKids) recently discovered how tumour cells sense and respond to tissue rigidity. (oicr.on.ca)
The research team found that a specific cell-surface ion channel, PIEZO1, regulates cell proliferation and tissue stiffening in glioma - the most common type of brain cancer. (oicr.on.ca)
In tumours, however, the study found that PIEZO1 detects the pressure caused by tissue stiffening and opens in response to the pressure, causing further cancer cell proliferation and tumour growth. (oicr.on.ca)
In the altered mechanical tissue environment of glioma, it promotes further stiffening of the tumour and fuels malignant growth. (oicr.on.ca)
Current treatment options are limited to surgical removal of the tumor and surrounding healthy brain tissue in combination with chemotherapy and radiation. (texaschildrens.org)

The researchers knew that cancer cells tend to have higher levels of the dimer. (stanford.edu)
They labeled one family member, DASA-23, with a radioactive carbon molecule, and they used PET scans to watch in laboratory mice as the labeled molecule sought out and bound to human glioblastoma cells implanted in the brains of the mice. (stanford.edu)
Using the technique, the brain cancer cells stood out clearly against a background of normal, noncancerous cells. (stanford.edu)

A mouse model of glioblastoma, an aggressive type of cancer that can occur in the brain, suggests that this recalcitrant cancer originates from a pool of stem cells that can be a significant distance away from the resulting tumors. (sciencedaily.com)
However, some recent research in glioblastoma patients shows that the subventricular zone (SVZ) -- an area that serves as the largest source of stem cells in the adult brain -- contains cells with cancer-driving mutations that are shared with tumors found in other often far-distant brain regions. (sciencedaily.com)
Starting from about 5.5 months old, these animals received weekly brain scans to look for tumors that arise when the stem cells subsequently acquire more mutations. (sciencedaily.com)
Using genetic tests and an approach akin to those used to study evolution, the researchers traced the cells that spurred both kinds of tumors back to the SVZ. (sciencedaily.com)
Although both single and multiple tumors had spontaneously acquired mutations in a gene called Pten, another type of tumor suppressor, precursor cells for the single tumors appeared to acquire this mutation before they left the SVZ, while precursor cells for the multiple tumors developed this mutation after they left the stem cell niche. (sciencedaily.com)
When the researchers genetically altered the animals to shut down the molecular pathway that loss of Pten activates, it didn't stop cancer cells from forming. (sciencedaily.com)
However, rather than migrate to distal areas of the brain, these malignant cells remained in the SVZ. (sciencedaily.com)
If new glioblastoma tumors are seeded by cells from a repository in the SVZ, he explains, attacking those tumors won't be enough to eradicate the cancer. (sciencedaily.com)
In mice, a fatal brainstem tumor was cleared by injecting it with engineered T cells that recognized the cancer and targeted it for destruction. (stanford.edu)
Engineered human immune cells can vanquish a deadly pediatric brain tumor in a mouse model, a study from the Stanford University School of Medicine has demonstrated. (stanford.edu)
In mice whose brainstems were implanted with human DIPG, engineered immune cells known as chimeric antigen receptor T cells - or CAR-T cells - were able to eliminate tumors, leaving very few residual cancer cells. (stanford.edu)
We gave CAR-T cells intravenously, and they tracked to the brain and cleared the tumor. (stanford.edu)
When the brains of the mice were examined via immunostaining after treatment, the animals had, on average, a few dozen cancer cells left, compared with tens of thousands of cancer cells in animals that received a control treatment. (stanford.edu)
However, some mice experienced dangerous levels of brain swelling, a side effect of the immune response triggered by the engineered cells, the researchers said, adding that extreme caution will be needed to introduce the approach in human clinical trials. (stanford.edu)
To begin the research, the scientists screened human DIPG tumor cultures for surface molecules that could act as targets for CAR-T cells. (stanford.edu)
Crystal Mackall says she is encouraged that the work in mice showed that engineered immune cells called CAR-T cells were able to eradicate the tumors in mice. (stanford.edu)
Next, the team tested the GD2 CAR-T cells in mice whose brainstem was implanted with human DIPG tumors, an experimental system that Monje's lab pioneered. (stanford.edu)
Seven to eight weeks after the tumor was established, each mouse received one intravenous injection of GD2 CAR-T cells or, as a control treatment, an injection of CAR-T cells that react to a different target. (stanford.edu)
The researchers also discovered that cannabinoids apparently worked by increasing the activity of ceramide, a lipid mediator of apoptosis, resulting in the functional inhibition of cells needed for VEGF production. (innovations-report.com)
However, when these germ cells don't move to the right area, they can become trapped in the brain and multiply in areas where they shouldn't. (dana-farber.org)

Johns Hopkins scientists have published laboratory data refuting studies that suggest blood vessels that form within brain cancers are largely made up of cancer cells. (hopkinsmedicine.org)
More recently, scientists in Italy and the Memorial Sloan Kettering Cancer Center in New York published results of studies suggesting that these tumor blood vessels are made by primitive types of brain cancer cells that are a form of stem cells. (hopkinsmedicine.org)
In their studies, they found tumor markers on blood vessel cells in 20 to 90 percent of their brain cancer samples. (hopkinsmedicine.org)

An exciting study conducted in the laboratories of Dr. Tiemo Klisch at the Jan and Dan Duncan Neurological Research Institute at Texas Children's Hospital , has identified new roles for Atonal homologue 1 (Atoh1) and the Janus Kinase 2 (Jak2) signaling pathway in regulating a particular type of medulloblastoma tumors. (texaschildrens.org)
Medulloblastoma is the most common malignant brain tumor in children and forms in the cerebellum, a region of the brain important for movement and spatial orientation. (texaschildrens.org)
Previously, Klisch and colleagues had observed that in the absence of Atoh1, formation of Shh-type medulloblastoma tumors is completely blocked, even if the Shh pathway was activated. (texaschildrens.org)
