Jararhagin is a metalloproteinase from Bothrops jararaca responsible for hemorrhage, inflammation, necrosis and edema. Effects of low doses of the toxin were analyzed on the energy metabolism of mice as well as its physiological implications. Measures of O 2 consumption (VO 2 ) were quantified after 4 and 24h of the jararhagin administration during four weeks. Hematocrit and histology...
Skmel-28 human melanoma cells were treated with jararhagin (Jara), a metalloproteinase disintegrin isolated from Bothrops jararaca snake venom, and Jari (Jara with the catalytic domain inactivated). Following treatments, monolayer cells lost cytoplasmic expansions acquiring round shapes, detached and formed cell clusters in suspension. Cytotoxicity effect of Jari was dramatically increased at concentrations...
