Muscle Tissue Damage Induced by the Venom of Bothrops asper: Identification of Early and Late Pathological Events through Proteomic Analysis
(2016-04-01)
The time-course of the pathological effects induced by the venom of the snake Bothrops asper in muscle tissue was investigated by a combination of histology, proteomic analysis of exudates collected in the vicinity of ...
Effect of the metalloproteinase inhibitor batimastat in the systemic toxicity induced by Bothrops asper snake venom: understanding the role of metalloproteinases in envenomation
(2014-03-15)
The peptidomimetic hydroxamate metalloproteinase inhibitor batimastat (BB-94) was assessed for its ability to neutralize the systemic effects (lethality, hemorrhage and coagulopathy) induced by the venom of Bothrops asper, ...
Hemorrhage induced by snake venom metalloproteinases: biochemical and biophysical mechanisms involved in microvessel damage
(2005-06-15)
Zinc-dependent metalloproteinases are responsible for the hemorrhagic activity characteristic of viperid snake venoms. Snake venom metalloproteinases (SVMPs) are classified in various groups (P-I–IV), according to their ...
Role of collagens and perlecan in microvascular stability: exploring the mechanism of capillary vessel damage by snake venom metalloproteinases
(2011-12-08)
Hemorrhage is a clinically important manifestation of viperid snakebite envenomings, and is induced by snake venom metalloproteinases (SVMPs). Hemorrhagic and non-hemorrhagic SVMPs hydrolyze some basement membrane (BM) and ...
Blood flow is required for rapid endothelial cell damage induced by a snake venom hemorrhagic metalloproteinase
(2006-01)
The effects of blood flow interruption on the ultrastructural alterations induced by a snake venom hemorrhagic metalloproteinase on skeletal muscle capillary endothelial cells were studied. Saline solution or the ...
Novel catalytically-inactive PII metalloproteinases from a viperid snake venom with substitutions in the canonical zinc-binding motif
(2016-10-12)
Snake venom metalloproteinases (SVMPs) play key biological roles in prey immobilization
and digestion. The majority of these activities depend on the hydrolysis of relevant protein substrates
in the tissues. Hereby, we ...
Homogenates of skeletal muscle injected with snake venom inhibit myogenic differentiation in cell culture
(2013-02)
Introduction: Viperid snakebite envenomings are characterized by muscle necrosis and a deficient regenerative response. Methods: Homogenates from gastrocnemius muscles of mice injected with the venom of the snake Bothrops ...
Wound exudate as a proteomic window to reveal different mechanisms of tissue damage by snake venom toxins
(2009)
In light of the complexity of wound tissue, proteomic analysis may not clearly reveal the nature of the wound or the processes involved in healing. However, exudate associated with wounds may provide a “window” on cellular ...
Metaloproteinasas dependientes de Zinc: Protagonistas centrales en la Fisiopatología de Envenenamientos por Serpientes de la familia Viperidae
(2016)
Se presenta y discute el papel que juegan las metaloproteinasas de los venenos de serpientes (SVMPs) de la familia Viperidae en la fisiopatología de los envenenamientos inducidos por mordeduras de estos reptiles. Se hace ...
Characterization of aspercetin, a platelet aggregating component from the venom of the snake Bothrops asper which induces thrombocytopenia and potentiates metalloproteinase-induced hemorrhage
(2001-04)
Thrombocytopenia occurs in a number of patients bitten by Bothrops asper, a species responsible for the majority of snakebites in Central America and southern Mexico. In this work we describe the isolation of a new ...
