Aug 19, 2021 · GsMTx-4 caused a small but insignificant decrease of Ca 2+ entry in platelets stimulated by the diacylglycerol analog 1-oleoyl-2-acetyl glycerol in hypertensive mice. In contrast, GsMTx-4 significantly inhibited Ca 2+ entry encouraged by Yoda1 (Figure S2). Together, these results indicated that Piezo1 rather than TCPC6 was the main target for ... Yoda1-evoked currents were blocked by Gd 3+ (30 µmol/L) and GsMTx-4 (2.5 µmol/L)—both of which inhibit Piezo1 as well as several other types of ion channels 35,36,38–40 (Figure 4C and 4D). The unitary conductance of Yoda1-induced currents in brain cortical cECs was ≈20 pS .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). Thrombus size was reduced 50% by GsMTx-4, independently of P2X1 receptors. In contrast, GsMTx-4 had no effect on collagen-induced aggregation or on Ca 2+ influx via TRPC6 or Orai1 channels and caused only a minor inhibition of P2X1-dependent Ca 2+ entry. The Piezo1 agonist, Yoda1, potentiated shear-dependent platelet Ca 2+ …GsMTx-4 decays the activities of single channels of nAChRs in HEK293T. To further verify this effect of GsMTx-4, we expressed nAChRs in HEK293T cells, which do not have endogenous receptors. cDNAs of the muscle-type nAChR subunits α, β, γ and δ were transfected into these cells, which led to the expression of nAChRs on the cell surface.

Sensing the energy from mechanical inputs is ubiquitous--and perhaps the oldest form of biological energy transduction. However, the tools available to probe the mechanisms of transduction are far fewer than for the chemical and electric field sensitive transducers. The one pharmacological tool avai …

(B) The percentage of cells responding to mechanical stretch with a greater than 50% increase in intracellular fluorescence levels without blocker (control), with Gd 3+, with GsMTx-4, with RR, or in Ca 2+-free solution.

GsMTx4 is a spider venom peptide that selectively inhibits cationic mechanosensitive channels (MSCs) such as TRPC1 and TRPC6 and Piezo channels. GsMTx4 blocks stretch-activated cation channels in astrocytes, cardiac cells, and smooth and skeletal muscle cells. GsMTx4 also inhibits TACAN, a mechanosensitive ion channel involved in the pain response. The spider toxin GsMTx‐4 blocks TRPV4 cation channels expressed in HEK‐293 cells. BiophysJ 108, 126a.

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.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).

Order from Sigma-Aldrich.We determined whether the effect of GsMTx-4 on [Ca 2+] i was restricted to entry of Ca 2+ through stretch-activated channels, since there is the possibility that GsMTx-4 might inhibit store-operated Ca 2+-permeable …GsMTx-4 is currently the best available antagonist for in vivo investigations of Piezo channels as it has high potency for Piezo channels atlower concentrations (28, 41). However, previous studies have suggested that GsMTx-4 may also in-hibit transient receptor potential cation (TRPC) channels, specifically mechanically activated TRPC1 …

The Piezo1 antagonist, GsMTx-4, caused a decrease in the extent of clot contraction relative to the control both in whole blood and in platelet-rich plasma. Activated Piezo1 in compressed and deformed RBCs amplified the platelet contractility as a positive feedback mechanism during clot contraction.Furthermore, GsMTx-4 reduced hyperalgesia to both mechanical and hypotonic stimuli in different models of inflammatory and neuropathic pain, although it had no effect on baseline mechanical nociceptive thresholds. TRPC1 and TRPC6, two GsMTx-4-sensitive SACs, are expressed in dorsal root ganglion (DRG) neurons.GsMTx-4 was purchased from Alomone Labs (Jerusalem, Israel) and TRAM-34 from Sigma-Aldrich (St. Louis, MO, USA). For both substances, stock solutions were prepared at 1 mM in aqua dest. Further applications were performed at concentrations indicated in the experimental description.

GsMTx-4 has not been previously reported to block anion channels. 1 µM GsMTx-4 had no effect on KCa3.1 activity in human AA cells treated with 1 µM A23187 in the presence of extracellular Ca 2+, measured as 86 Rb influx and as cell shrinkage (n = 3 for each method, not shown
