Circ_NNT protected ARPE-19 cells against HG-evoked apoptosis and inflammation via elevating TIMP3 through sequestering miR-320b, indicating that up-regulation of circ_NNT might contribute to the inhibition of DR process.
Circ_NNT suppresses the apoptosis and inflammation in glucose-induced human retinal pigment epithelium by regulating miR-320b/TIMP3 axis in diabetic retinopathy.
