ENP graduate student Shauna Katz contributed to a review on microRNA-9 (miR-9), a regulator of neurogenesis. Katz and her colleagues discussed the findings that miR-9 targets transcriptional regulators that are known to control progenitor state, even in adult neural stem cells. Some studies alternatively indicate that miR-9 has functions in differentiated neurons. MiR-9 has been linked to pathological states, though it is unclear if it serves to protect from neurodegeneration or if it contributes to disease progression. Get more information in the review:
