By up-regulating μ- and δ-opioid receptors, neuron-restrictive silencer factor knockdown promotes neurological recovery after ischemia.

ABSTRACT: We investigated the effects of neuron-restrictive silencer factor (NRSF) on proliferation of endogenous nerve stem cells (NSCs) and on μ- and δ-opioid receptor (MOR/DOR) expression in rats after cerebral ischemia. Among 100 rats subjected to cerebral ischemia, 20 rats were transfected with NRSF shRNA, and the remaining 80 were randomly assigned to normal, sham, model, and negative control (NC) groups. On days 7, 14, and 28 after ischemia and reperfusion, neurological function scores were assigned and a step-down passive avoidance test was conducted. Nerve function scores, step-down reaction periods, error times and apoptosis rates, as well as levels of B-cell CLL/lymphoma 2 (Bcl-2), BCL2-associated X protein (Bax), and NRSF expression were lower in the NRSF shRNA group than in the model an
