Japanese researchers have found a method of blocking the growth of human brain tumor cells, suppressing their migration and inducing programmed cell death, according to a study in the U.S. online science magazine Nature Medicine.

The team, led by Shogo Ishiuchi, a teaching assistant at Gunma University’s department of neurosurgery, examined the role of calcium-permeable glutamate receptors on cells of glioblastoma and found that making them calcium-impermeable inhibited tumor cell migration, according to the study.
