PIEZO1 and glioblastoma: We used GsMTx‐4 to inhibit Piezo1, since this molecule is the only known pharmacological inhibitor of cationic MSCs (Figure S4, Supporting Information).[47, 48, 49, 50] Previously in our lab we have shown that pre‐treatment of PC3 cells with GsMTx‐4 followed by exposure to low‐intensity FSS+TRAIL allowed for higher cell viability compared to the FSS+TRAIL condition.[12] We have also seen that treatment of LN18 glioblastoma cells with GsMTx‐4 reduced Ca2+ influx into the cells treated with Yoda1.[23]
