Figure 6From: Promoter methylation and downregulation of SLC22A18 are associated with the development and progression of human gliomaPCR amplification of SLC22A18 in U251-SLC22A18 stable cell lines. M, DNA molecular mass marker; lane 1, culture medium only control; lane 2, empty plasmid transfected U251-EV cells; lane 3, untransfected U251 cells; lane 4, U251-SLC22A18 cells.Back to article page
