Study reveals neural stem cells age rapidly

In a new study published in Cell Stem Cell, a team led by USC Stem Cell scientist Michael Bonaguidi, Ph.D., demonstrates that neural stem cells—the stem cells of the nervous system—age rapidly. “There is chronological aging, and there is biological aging, and they are not the same thing,” said Bonaguidi, an Assistant Professor of Stem […]

Biotin, mitochondria, and dementia: Research reveals a connection

By any measure, carbon-based life originates from carboxylation. That is to say, the coupling of atmospheric carbon dioxide to sugar. Carboxylation is also critical for mitochondria to function. There are five carboxylation enzymes in mitochondria, and they share one thing in common—they are all operated by a covalently linked biotin cofactor. Biotin is also known […]
