LINC01198 and glioma: After detecting the expression levels of LINC01198 in six glioma cell lines, two normal brain tissues, and two glioma tissues, we performed knockdown of LINC01198 in U87 and LN229 cells that had high LINC01198 expression and upregulated its expression in U251 and SNB-19 cells that had low LINC01198 expression (Figure 2A–2C).
