GsMTx-4 accelerates the desensitization of muscle-type nAChRs in C2C12 myotubes Previously, 1 μM GsMTx-4 was used to block the mechanosensitivity of muscle-type nAChRs [25]. During the experiment, toxic inhibition of the nAChR single channel was observed. To determine the properties of GsMTx-4-mediated inhibition,However, MsC activity only accounted for about 4 mV of this depolarisation (E m ∼−61 mV in the presence of 5 µM GsMTx-4). Interestingly, under hypertonic conditions, E m was more negative at −61 mV with a similar further repolarisation in the presence of GsMTx-4 as seen under isotonic conditions. This rules out a major contribution from ...

The GsMTx-4 peptide isolated from tarantula venom is a specific modifier of nonselective mechanosensitive channels . Its inhibitory action is within the outer membrane leaflet and is considered to be through altering the distortion of the boundary lipids adjacent to the channel that occurs during membrane stretch ( 16 , 17 ).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 …In addition, GsMTx treatment profoundly suppressed the frequency of calcium sparks around RasV12 cells (Figures 6 B–6D; Video S4). Furthermore, RasV12 expression induced the increased movement of the surrounding cells, which was suppressed by GsMTx (Figures 6 E–6G). GsMTx also diminished the movement of RasV12 cells (Figures 6 F …

GsMTx-4 blockade also attenuated the cardioaccelerator response at multiple time points during the muscle contraction in CTL rats (Fig. 3E).

Meanwhile, ox-LDL also upregulates Piezo1 and inflammation proteins (NF-κB, JNK and TNF-α) in endothelium cells (ECs).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 .The transient receptor potential channel TRPV4 is a calcium conducting, osmosensitive cation channel and expressed in motoneurons and skeletal muscles. In mouse muscle fibers TRPV4 forms or contributes to a mechanosensitive cation channel. The molecular architecture of this channel is still unclear. Since mechanosensitive cation …GsMTx-4 also markedly reduces the sensitization to hypotonic stimuli. GsMTx-4 inhibits the mechanical hyperalgesia induced by combinations of inflammatory mediators, carrageenan, or paclitaxel to the same extent as spinal intrathecal administration of ODN antisense to TRPV4 (Alessandri-Haber et al., 2004, 2006).Oct 6, 2016 · Supporting the generic lack of amphipath activity, Iwasa (personal communication) showed that GsMTx-4, even at saturating doses, does not alter the shape of red blood cells (Sheetz et al., 1976;Sheetz and Singer, 1974). Presumably this is because there is an insufficient number density to change the intrinsic curvature. The GsMTx-4 peptide also blocked the activation of TRPC6 channels by either receptor-induced PLC activation or by direct application of diacylglycerol. The effects of the peptide on both stretch- and diacylglycerol-mediated TRPC6 activation indicate that the mechanical and chemical lipid sensing by the channel has a common molecular …
