Morphine Modulates Mouse Hippocampal Progenitor Cell Lineages by Upregulating miR‐181a Level
Abstract The mechanism by which addictive drugs such as morphine regulate adult neurogenesis remains elusive. We now demonstrate that morphine can regulate neurogenesis by control of miR‐181a and subsequent hippocampal neural progenitor cell (hNPC) lineages. In the presence of morphine, hNPCs preferentially differentiated into astrocytes, an effect blocked by the specific μ‐opioid receptor antagonist, Cys2‐Tyr3‐Orn5‐Pen7‐amide. This effect was mediated by the Prox1/Notch1 pathway as demonstrated by an increase in Notch1 level in the morphine‐ but not fentanyl‐treated hNPCs and blocked by overexpression of ...
