Abstract Background: During Enterovirus type 71 (EV71) infection, the structural viral protein 1 (VP1) activates endoplasmic reticulum (ER) stress associated with peripheral myelin protein 22 (PMP22) accumulation and induces autophagy. However, the specific mechanism behind this process remains elusive. Methods: In this research, we used the VP1-overexpressing mouse Schwann cells (SCs) models co-transfected with a PMP22 silencing or Autocrine motility factor receptor (AMFR/gp78) overexpressing vector to explore the regulation of gp78 on PMP22 and its relationship with autophagy and apoptosis. Results: The activity of gp78 could be influenced by EV71-VP1, leading to a decrease in the ubiquitination and degradation of PMP22,… More >

Abstract Peripheral nerve injury is a common neurodegenerative disease, which causes disability and a huge economic burden for patients. MicroRNAs (miRNAs) have been acknowledged as major regulators and therapeutic targets of neurological disease. Thus, the functional studies of miRNAs in neurological disease will contribute to discover new therapeutic targets for peripheral nerve injury. Sprague Dawley rats treated sciatic nerve surgical injury were regarded as peripheral nerve injury model in vivo. The expression of miR-494-3p and Kruppel like factor7 (KLF7) were measured by Real-time quantitative polymerase chain reaction (RT-qPCR) assay. In addition, western blot analysis was conducted to measure the protein levels… More >
