Further, RT-qPCR results showed that treatment with sh-LINC00470-1 and sh-LINC00470-2 reduced the expression of LINC00470 in KLE cells, and treatment with oe-LINC00470 enhanced the expression of LINC00470 in HEC-1-B cells, which validated the successful infection of LINC00470 (Figure 2B). Here, LINC00470 is linked to infection.
