Chen et al. reported that lncRNA ROR can promote the cerebral hypoxia/reoxygenation (H/R) injury in PC12 cells in vitro, a cellular model of cerebral ischemia/reperfusion injury, through inhibiting the expression of miR-135a-5p or upregulating the expression of ROCK1 and ROCK2 [28]. The gene discussed is ROCK1; the disease is brain ischemia.
