CPB2 and central nervous system cancer: Furthermore, we examined the expression of the signature lncRNAs in cell lines U251 and T98G as tumor group, SVGp12 as normal or control group, by qPCR (Figure 11) analysis, showing that the expression of CPB2-AS1, MIR155HG, LINC00906 and WDR11-AS1 were low in gliomas cells.
