CCL21 and glioblastoma: Transport is a biological process enriched among miR-137 affected genes in glioblastoma cells; in this category, we identified several members of the solute carrier family (SLC) (SLC16A9, SLC1A2, SLC1A5, SLC25A5 SLC35A4, SLC43A2, SLC45A3, SLC6A8, SLC4A7, SLC7A2) which codes for membrane transport proteins.
