Gsmtx.

GsMTx4 is a spider venom peptide that selectively inhibits cationic-permeable mechanosensitive channels (MSCs) belonging to the Piezo and TRP channel families. GsMTx4 also blocks cation-selective stretch-activated channels (SACs) , attenuates lysophosphatidylcholine (LPC)-induced astrocyte toxicity and microglial reactivity. …

Results: Our results displayed that antagonist GsMTx-4 effectively inhibited calcium influx caused by hypertension and agonist Yoda1. Antithrombotic studies proved that the inhibition of Piezo1 effectively inhibited arterial thrombosis and reduced the infarct size of stroke in hypertensive mice.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).Pharmacologically, the Piezo channels are inhibited by the mechanosensitive channel blockers gadolinium (Gd 3+) and ruthenium red (RR), and specifically by the peptide blocker GsMTx-4 (Bae, Sachs, & Gottlieb, 2011; Coste et al., 2010, 2012; Gottlieb & Sachs, 2012). The Piezo channels have quickly found significance in several mechanosensitive ...GsMTx-4 is a peptide toxin isolated from the Chilean rose tarantula that broadly inhibits mechanosensitive ion channels 35, 36.

These data suggest that Piezo channels are an effective target to normalize the exercise pressor reflex in T1DM.

The negative inotropic effect of GsMtx-4 in atrium is concentration-dependent. At 1000 nmol/L GsMtx-4, the highest concentration tested, basal twitch force decreased by 12 ± 3% (n = 4, p < 0.05). In ventricle, on the other hand, there was no significant effect of GsMtx-4 on basal force up to a concentration of 1000 nmol/L.

After incubation with either Yoda1 or GsMTx-4, blood was clotted with thrombin, and the size of the macroscopic clot was tracked optically in parallel with the control samples.
