Metabolic State of Brain Cancer Stem Cells Significantly Different than the Cancer Cells They Create

The metabolic state of glioma stem cells, which give rise to deadly glioblastomas, is significantly different from that of the brain cancer cells to which they give birth, a factor which helps those stem cells avoid treatment and cause recurrence later.

Researchers with the UCLA Department of Radiation Oncology at UCLA’s Jonsson Comprehensive Cancer Center also found for the first time that these glioma stem cells can change their metabolic state at will, from glycolysis, which uses glucose, to oxidative phosphorylation, which uses oxygen.

The glioma stem cells’ ability to change their metabolic state at will also allow these stem cells

Stem cells help brain heal after radiation

Scientists at the University of California have found a potential new use for human embryonic stem cells: helping cancer patients recover the cognitive function lost when their brains are treated with radiation.

People with tumors in their head or neck often undergo radiation therapy after the cancer is surgically removed. Radiation helps kill malignant cells left behind. But it also can debilitate the hippocampus, the brain region responsible for learning, memory and processing of spatial information.

The researchers wondered whether embryonic stem cells could pick up the slack.

So they radiated the heads of 18 rats. Two days later, six of those
