SLC13A5 and glioblastoma: A whole-genome integrative analysis of methylation and the gene expression profiles in glioblastoma and normal brain tissues reveals that SLC13A5 is one of the 13 genes with concordant CpG islands in their promoter regions and the hypermethylation of the CpG sites of SLC13A5 is inversely correlated to its low expression in glioblastomas [91].
