So how do animals play a role in this research? Well, in a couple of ways. First, the chlorotoxin in Tumor Paint was derived from scorpion venom. Second, researchers worked with dogs before moving into human trials to determine the likelihood of success. After promising results in canines, human trials are now underway at Cedars Sinai Medical Center! Right now, the study is aimed at proving that Tumor Paint is able to reach the brain tumor successfully. If all goes well, it's possible that this could lead to more successful surgical outcomes.

A multicenter study has identified an FDA-approved medication that prolongs survival in mice with diffuse intrinsic pontine glioma, a brain tumor that now lacks chemotherapy treatments.

Cancer usually begins with one tumor in a specific area of the body. But if the tumor is not removed, cancer has the ability to spread to nearby organs as well as places far away from the origin, like the brain. How does cancer move to these new areas and why are some organs more likely to get infected than others? Ivan Seah Yu Jun explains the three common routes of metastasis.

An Indiana woman undergoing surgery in Los Angeles to remove a tumor experienced a twist worthy of a sci-fi plot when doctors discovered an embryonic twin in her brain.

Panobinostat is a new type of drug that works by blocking an enzyme responsible for modifying DNA at the epigenetic level. Epigenetics refers to chemical marks on DNA itself or on the protein "spools" called histones that package DNA. These marks influence the activity of genes without changing the underlying sequence, essentially acting as volume knobs for genes. Earlier genomic studies showed that about 80 percent of DIPG tumors carry a mutation that alters a histone protein, resulting in changes to the way DNA is packaged and tagged with those chemical marks. This faulty epigenetic regulation results in activation of growth-promoting genes that should have been turned off, and shutdown of others that should have acted as brakes to cell multiplication. Cancer is the result. Panobinostat appears to work by restoring proper functioning of the cells' chemical tagging system.
