HCP5 and central nervous system cancer: For further confirmation, the expression of CYB561D2, DLEU1, HCP5 and OR7E156P were examined in a human fetal glial cell line, SVG p12, and four glioma cell lines, U87-MG, T98-G, U251-MGU251-MG MG, and LN229; Figure 1B reveals that the expression of all the four lncRNAs was significantly upregulated in all the four glioma cell lines compared with that in the SVG p12 cell line; among the four lncRNAs, OR7E156P was more upregulated.
