Hypothalamic stem cells control ageing speed partly through exosomal miRNAs. Nature, 2017; DOI: 10.1038/nature23282

Scientists at Albert Einstein College of Medicine have found that stem cells in the brain’s hypothalamus govern how fast aging occurs in the body. The finding, made in mice, could lead to new strategies for warding off age-related diseases and extending lifespan. The hypothalamus was known to regulate important processes including growth, development, reproduction and metabolism. In a 2013 Nature paper, Einstein researchers made the surprising finding that the hypothalamus also regulates aging throughout the body...

Researchers have shown that a metabolic pathway associated with slowing aging also drives brain cancer. In the image above, cancer stem cells in a mouse brain section glow fluorescent green, allowing researchers to study the effect of inhibiting the pathway on the ability of cancer stem cells to survive and proliferate.

While a particular metabolic pathway shows potential to slow down the aging process, new research indicates a downside: That same pathway may drive brain cancer. The pathway, known as the nicotinamide adenine dinucleotide (NAD+) pathway, is overactive in a most deadly form of brain cancer, glioblastoma, according to a study by researchers at Washington University School of Medicine in St. Louis...
