Saxitoxin 0-9 Fos proto-oncogene, AP-1 transcription factor subunit Rattus norvegicus 83-88 9620576-5 1998 Saxiphilin is a novel transferrin which binds saxitoxin (STX) but differs from the sodium channel in not having any measurable affinity for TTX. Saxitoxin 46-55 transferrin Mus musculus 22-33 9620576-5 1998 Saxiphilin is a novel transferrin which binds saxitoxin (STX) but differs from the sodium channel in not having any measurable affinity for TTX. Saxitoxin 57-60 transferrin Mus musculus 22-33 9397515-1 1998 Saxitoxin (STX) binding was measured in susceptible (SBO) and pyrethroid-resistant (KDR) female houseflies having only target site insensitivity as a resistance mechanism. Saxitoxin 0-9 kinase insert domain receptor Homo sapiens 84-87 9397515-1 1998 Saxitoxin (STX) binding was measured in susceptible (SBO) and pyrethroid-resistant (KDR) female houseflies having only target site insensitivity as a resistance mechanism. Saxitoxin 11-14 kinase insert domain receptor Homo sapiens 84-87 9397515-2 1998 In KDR flies, there was a quantitative decrease in STX binding capacity (Bmax) relative to SBO flies coupled with an increase in binding affinity (Kd). Saxitoxin 51-54 kinase insert domain receptor Homo sapiens 3-6 9397515-7 1998 The data suggest that the kdr resistant gene may be expressed as changes in STX binding kinetics and that measurements of STX binding in pyrethroid-treated insects may be a useful approach for studying pyrethroid"s mode of action and resistance. Saxitoxin 76-79 kinase insert domain receptor Homo sapiens 26-29 9068974-4 1997 ET-3-and ETB-receptor-selective agonist STX S6c enhanced EFS-induced contractions. Saxitoxin 40-43 endothelin receptor type B Rattus norvegicus 9-12 8926643-1 1995 The authors have reported that ET-1 and ETB receptor agonist, sarafotoxin S6c (STX-S6c), caused prolonged intraocular pressure (IOP) reduction in rabbit eyes in a dose-dependent fashion when injected intravitreally. Saxitoxin 79-82 endothelin-1 Oryctolagus cuniculus 31-52 8858921-6 1996 Stimulatory effects of insulin on [3H]-STX binding and veratridine-induced 22Na+ influx were nullified by simultaneous treatment with either 5,6-dichlorobenzimidazole riboside, an inhibitor of RNA synthesis, or cycloheximide, an inhibitor of protein synthesis, whereas insulin treatment did not appreciably increase the level of mRNA encoding the Na+ channel alpha-subunit. Saxitoxin 39-42 insulin Bos taurus 23-30 9086773-4 1997 In evolution, it is intriguining that the virulent genes of EHEC might be mediated by phages, plasmids and so on, because stx is derived from a bacterio-phage, bfpA is located in a plasmid in enteropathogenic E. coli(EPEC) though it has not yet been cloned in EHEC, eaeA is one of the genes in LEE(locus of enterocyte effacement), a putative genetic cassette ubiquitous for EPEC and EHEC, and ehxA is in a plasmid. Saxitoxin 122-125 Major pilin structural unit bundlin Escherichia coli 160-164 8858921-1 1996 Treatment of cultured bovine adrenal chromaffin cells with 100 nM insulin raised [3H]saxitoxin ([3H]-STX) binding in a time-dependent manner (t1/2 = 26 h). Saxitoxin 101-104 insulin Bos taurus 66-73 8858921-2 1996 Insulin (100 nM for 4 days) increased the Bmax of [3H]STX binding by 49% without changing the KD value and also augmented the maximal influx of 22Na+ due to 560 microM veratridine by 39% without altering the EC50 value of veratridine. Saxitoxin 54-57 insulin Bos taurus 0-7 8537816-1 1995 bTyrosine 401 of the skeletal muscle isoform (mu 1) of the rat muscle Na channel is an important determinant of high affinity block by tetrodotoxin (TTX) and saxitoxin (STX) in Na-channel isoforms. Saxitoxin 158-167 sodium voltage-gated channel alpha subunit 4 Rattus norvegicus 21-51 8537816-1 1995 bTyrosine 401 of the skeletal muscle isoform (mu 1) of the rat muscle Na channel is an important determinant of high affinity block by tetrodotoxin (TTX) and saxitoxin (STX) in Na-channel isoforms. Saxitoxin 158-167 ST8 alpha-N-acetyl-neuraminide alpha-2,8-sialyltransferase 2 Homo sapiens 169-172 7706028-3 1995 The authors attempted to clarify the role of ETB receptors in changes in IOP induced by ET-1 in rabbits using STX-S6c and to determine the relationship between the IOP response and various doses of STX-S6c. Saxitoxin 110-113 endothelin receptor type B Oryctolagus cuniculus 45-48 7706028-14 1995 CONCLUSION: STX-S6c reduces the IOP in rabbits in a dose-dependent fashion, presumably mediated through the ETB receptors. Saxitoxin 12-15 endothelin receptor type B Oryctolagus cuniculus 108-111 8391763-2 1993 The tritiated sodium channel blocker saxitoxin ([3H]-saxitoxin; STX) was used to detect toxins in paralytic shellfish poisoning (PSP) by measuring the competitive displacement of other toxins.
