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 ...
Tissue Localization and Extracellular Matrix Degradation by PI, PII and PIII Snake Venom Metalloproteinases: Clues on the Mechanisms of Venom-Induced Hemorrhage
(2015-04-24)
Snake venom hemorrhagic metalloproteinases (SVMPs) of the PI, PII and PIII classes were
compared in terms of tissue localization and their ability to hydrolyze basement membrane
components in vivo, as well as by a ...
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 ...
Experimental pathology of local tissue damage induced by Bothrops asper snake venom
(2009-12-01)
Envenomations by Bothrops asper are often associated with complex and severe local pathological manifestations, including edema, blistering, dermonecrosis, myonecrosis and hemorrhage. The pathogenesis of these alterations ...
Effectiveness of batimastat, a synthetic inhibitor of matrix metalloproteinases, in neutralizing local tissue damage induced by BaP1, a hemorrhagic metalloproteinase from the venom of the snake Bothrops asper
(2000-07-15)
Batimastat (BB-94), a synthetic hydroxamate peptidomimetic matrix metalloproteinase inhibitor, was tested for its ability to inhibit proteolytic and toxic effects induced by BaP1, a 24-kDa hemorrhagic metalloproteinase ...
Bothrops asper metalloproteinase BaP1 is inhibited by alpha(2)-macroglobulin and mouse serum and does not induce systemic hemorrhage or coagulopathy
(2004-02)
The ability of the P-I metalloproteinase BaP1, isolated from the venom of the snake Bothrops asper, to induce systemic bleeding, thrombocytopenia and defibrinogenation was assessed in an experimental mouse model. Intravenous ...
Skin Pathology Induced by Snake Venom Metalloproteinase: Acute Damage, Revascularization, and Re-epithelization in a Mouse Ear Model
(2008-10)
Viperid snakebite envenomation induces blistering and dermonecrosis. The pathological alterations induced by a snake venom metalloproteinase in the skin were investigated in a mouse ear model. Metalloproteinase BaP1, from ...
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 ...
Proteomics of Wound Exudate in Snake Venom-Induced Pathology: Search for Biomarkers To Assess Tissue Damage and Therapeutic Success
(2011-02-10)
Tissue damage analysis by traditional laboratory techniques is problematic. Proteomic analysis of exudates collected from affected tissue constitutes a powerful approach to assess tissue alterations, since biomarkers ...
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 ...
