Our previous RNA sequencing study showed that the long non-coding RNA ischemia-related factor Vof-16(lncRNA Vof-16)was upregulated after spinal cord injury,but its precise role in spinal cord injury remains unclear.Bioinformatics predictions have indicated that lncRNA Vof-16 may participate in the pathophysiological processes of inflammation and apoptosis.PC12 cells were transfected with a pHBLV-U6-MCS-CMV-ZsGreen-PGK-PURO vector to express an lncRNA Vof-16 knockdown lentivirus and a pHLV-CMVIE-ZsGree-Puro vector to express an lncRNA Vof-16 overexpression lentivirus.The overexpression of lncRNA Vof-16 inhibited PC12 cell survival,proliferation,migration,and neurite extension,whereas lncRNA Vof-16 knockdown lentiviral vector resulted in the opposite effects in PC12 cells.Western blot assay results showed that the overexpression of lncRNA Vof-16 increased the protein expression levels of interleukin 6,tumor necrosis factor-α,and Caspase-3 and decreased Bcl-2 expression levels in PC12 cells.Furthermore,we established rat models of spinal cord injury using the complete transection at T10.Spinal cord injury model rats were injected with the lncRNA Vof-16 knockdown or overexpression lentiviral vectors immediately after injury.At 7 days after spinal cord injury,rats treated with lncRNA Vof-16 knockdown displayed increased neuronal survival and enhanced axonal extension.At 8 weeks after spinal cord injury,rats treated with the lncRNA Vof-16 knockdown lentiviral vector displayed improved neurological function in the hind limb.Notably,lncRNA Vof-16 knockdown injection increased Bcl-2 expression and decreased tumor necrosis factor-αand Caspase-3 expression in treated animals.Rats treated with the lncRNA Vof-16 overexpression lentiviral vector displayed opposite trends.These findings suggested that lncRNA Vof-16 is associated with the regulation of inflammation and apoptosis.The inhibition of lncRNA Vof-16 may be useful for promoting nerve regeneration and functional recovery after spinal cord injury.The experiments were app
