Nrdp1 increases neuron apoptosis via downregulation of Bruce following intracerebral haemorrhage
Abstract Background Neuregulin receptor degradation protein-1 (Nrdp1) is an E3 ubiquitin ligase that plays an important role in regulating cell growth, apoptosis and oxidative stress. However, the data regarding its expression and exact mechanism in neuronal injury following ICH has not been well id...
