To identify the effect of LINC00941, we constructed stable LINC00941 knockdown A549 and NCI-1299 NSCLC cells endogenously silencing LINC00941, and exogenously overexpressed LINC00941 in A549 and NCI-1299 cells via retroviral infection, qRT-PCR showed the LINC00941 level in cell lines (Figure 2A). The gene discussed is LINC00941; the disease is non-small cell lung carcinoma.
