Chemosphere, 2018
Saxitoxin (STX), a paralytic shellfish toxin (PST) produced from toxic bloom-forming dinoflagellates, was selected to comparatively investigate the induction of cytotoxicity and apoptosis and a possible mechanism based on changes in the antioxidant defence system of two cellular strains: the mouse neuroblastoma cell line Neuro-2a and the rainbow trout ...

Effects of saxitoxin (STX; 10 micrograms/kg; i.p.) on cardio-respiratory activities were evaluated in urethane-anesthetized guinea-pigs. Concurrent recordings were made of electrocorticogram (ECoG), bulbar respiratory-related unit activities, diaphragmatic electromyogram (DEMG), electrocardiogram (Lead II ECG), blood pressure, heart rate, end-tidal CO2,

Reversal of saxitoxin (STX; 10 micrograms/kg, ip) induced cardiorespiratory effects by oxygen ventilation and burro-raised alpha-STX antitoxin (60 mg/kg, i.v.) was studied in urethane-anesthetized guinea pigs acutely instrumented for concurrent monitoring of medullary respiratory-related single units, diaphragm EMG, Lead II electrocardiogram, arterial ...

Mechanism of Action of Tetrodotoxin (TTX) and Saxitoxin (STX)
1971Marine toxins such as TTX and STX have aroused the interest of physiologists, biochemists, pharmacologists, and biological warfare people, as well as writers of spy and mystery stories. In the hands of the neuroscientist they have been turned into helpful instruments vital for the study of nerve function and excitable membranes.

Science of The Total Environment, 2022
Temperature may affect the production of saxitoxin (STX) and its derivatives (STXs); however, this is still controversial. Further, STX-biosynthesis gene regulation and the relation of its toxicity with temperature are not clearly understood. In the present study, we evaluated the effects of different temperatures (12 °C, 16 °C, and 20 °C) on the ...
