A research team at UC San Francisco has discovered an RNA molecule called Pnky that can be manipulated to increase the production of neurons from neural stem cells.
The research, led by neurosurgeon Daniel A. Lim, MD, PhD, and published on March 19, 2015 in Cell Stem Cell, has possible applications in regenerative medicine, including treatments of such disorders as Alzheimer’s disease, Parkinson’s disease and traumatic brain injury, and in cancer treatment.
Co-first authors Alex Ramos, PhD, now a third year medical student in the UCSF MSTP, and Rebecca Andersen, who are students in Lim’s laboratory, first studied Pnky in neural stem cells found in mouse brains, and also identified the molecule in neural stem cells of the developing human brain. They found that when Pnky was removed from stem cells in a process called knockdown, neuron production increased three to four times. Read more about Alex's work here.
