描述 | GsMTx4 is a spider venom peptide that inhibits cationic mechanosensitive channels (MSCs). GsMTx4 is an important pharmacological tool for identifying the role of these excitatory MSCs in normal physiology and pathology[1][2]. GsMTx4 (2.5 μM, 16 h) significantly diminishes both the leptin-induced AMPK and MLC-2 phosphorylation in breast epithelial cells (MCF10A) [3]. GsMTx4 (500 nM, 48 h) attenuates demyelination induced by the cytotoxic lipid and psychosine (organotypic cerebellar slices). GsMTx4 (stereotactic injection, 3 μM of 1 μL, a single dose) is neuroprotective and inhibits lysophosphatidylcholine-induced astrocyte toxicity and demyelination in the cerebral cortex[4]. GsMTx-4 (intraperitoneal injection, 270 μg/kg for a single dose) reduces mechanical allodynia induced by inflammation and by sciatic nerve injury in Von Frey test[5]. |
