The results suggested that (Figure 1B) there were varying degrees of higher expression of FOXD2-AS1 in 4 kinds of glioma cells in contrast with HEB cells (all P < 0.05), of which FOXD2-AS1 was obviously expressed in the U87 and U251 cell lines, which were chosen for subsequent experiments. The gene discussed is FOXD2; the disease is central nervous system cancer.
