The effects of Smad6 via small RNA pathways on the ischemic injury in PC12 cells.

Background: Though we have reported the neuroprotective effect of exogenous ActA on oxygen-glucose deprivation (OGD) injury, the endogenous role of Smad6 remains not well understood. Smad6 is an important regulator of the ActA/smads signaling via a negative feedback circuit.

Methods: In this study, nerve growth factor (NGF) and OGD were used to stimulate (rat adrenal pheochromocytoma) PC12 cells converting them into neurons to establish an ischemia in vitro model.
