The result manifested that the wound closure rate of PANC-1 and BxPC-3 cell lines was greatly decreased by LINC01857 knockdown in comparison with the control group, and the wound closure rate of the cancer cells was markedly decreased by LINC01857 downregulation (Fig. 2E‒F), indicating that LINC01857 knockdown repressed PDAC cell migration. The gene discussed is LINC01857; the disease is cancer.
