TRPM7 and glioblastoma: Recent studies suggested that both PGE2 and TRPM7 played key roles in proliferation, migration and invasion of human glioblastoma cells.4, 24, 25, 26, 27, 28 Previous studies suggested that TRPM7 could be modulated by G‐protein‐coupled receptors.19, 29 As PGE2 exerts its biological effects by G‐protein‐coupled receptors, we hypothesise that there is a crosstalk between PGE2 and TRPM7 in the regulation of proliferation and migration of glioblastoma cells.
