Western blotting was performed as previously described [20 (link)]. The blots were incubated overnight with primary antibodies targeting β-actin (Santa Cruz), Piezo1 (Poteintech), NFAT1 (Santa Cruz), NFAT2 (Santa Cruz), NFAT3 (Santa Cruz), NFAT4 (Santa Cruz), and TBP (Abcam) at 4 °C with constant shaking. After incubating with HRP-labeled secondary antibodies (Cell Signaling) at room temperature for 2 h, the protein bands were detected using the Pierce™ ECL Western Blotting Substrate (Thermo Scientific).
