Treatment with 2 mM NaVPA–3 mM NaDCA significantly increased the expression of SLC12A2 in GBM5-1F and GBM5-2F cells (130% and 200%, respectively), but upregulation of SLC12A2 was not significantly different between GBM5-1F and GBM5-2F tumor cells after treatment with NaVPA–NaDCA. This evidence concerns the gene SLC12A2 and neoplasm.
