CHERP and neuroblastoma: To verify the importance of CHERP in neuroblastoma, we employed a lentivirus system carrying small hairpin RNA (shRNA) to construct plasmids against target genes and then used these reconstructed lentiviruses (CHERPsi-1#, CHERPsi-2#, and GFPsi as a control) to infect BE(2)-C and SHEP1 cells.
