GsMTx-4 is peptide toxin with reversible inhibition of Piezo1 activities and maximum Kd of 2 μM, commonly employed in Piezo1 researches. To characterize the current-voltage relation, we applied ramped pulses from –100 to +100 mV at 5-second intervals. The flow-induced current was markedly inhibited in the presence of GsMTx-4 (Figure 4, I and J), indicating that Piezo1 mediates cellular current in C2C12 myotubes in response to mechanical stimulation.

GsMTx-4 may be a cardioprotective agent in patients with TRPC6 risk variants. Replication of the genetic associations in larger well-characterized samples and functional studies are required. Replication of the genetic associations in larger well-characterized samples and functional studies are required.

GsMTx-4 blockade also attenuated the cardioaccelerator response at multiple time points during the muscle contraction in CTL rats (Fig. 3E). Specifically, GsMTx-4 blockade attenuated the cardioaccelerator response 5 s after contraction onset and lasted throughout the muscle contraction (all: P < 0.05).

Surprisingly, GsMTx-4 did not lead to an inhibition of TRPA1 currents but to a massive increase in whole-cell currents , exhibiting similar properties as TRPA1 with a reversal potential close to zero and marked outward rectification. We next wanted to know whether GsMTx-4 can activate TRPA1 channels also in the absence of another stimulus. Pharmacological inhibition of Piezo1 (GsMTx-4) attenuated plaque formation, decreased the level of inflammation related factors (JNK, TNF-α, NF-κB, VCAM-1) of carotid plaque in atherosclerotic mice. Meanwhile, ox-LDL also upregulates Piezo1 and inflammation proteins (NF-κB, JNK and TNF-α) in endothelium cells (ECs).
