Article Title: Chemical Activation and Mechanical Sensitization of Piezo1 Enhance TRAIL-Mediated Apoptosis in Glioblastoma Cells
doi: 10.1021/acsomega.3c00705
Figure Lengend Snippet: Yoda1 + TRAIL apoptotic pathway. (A) Yoda1 is able to activate Piezo1, a mechanosensitive ion channel, under static conditions. This leads to Ca 2+ influx and a signaling cascade that enhances TRAIL-induced permeabilization of the mitochondria, resulting in increased apoptosis. (B) GsMTx-4 inhibits Piezo1 and other mechanosensitive ion channels, decreasing Ca 2+ influx and the synergistic effects of Yoda1. (C) Calpeptin inhibits calpain, decreasing the effect of extracellular Ca 2+ and leading to increased cell viability following treatment. (D) Bax channel blocker (BCB) inhibits Bax, blocking the effects of both Yoda1 and TRAIL, largely increasing cell viability.
