1. ADAMTS proteoglycanases downregulation with impaired oocyte quality in PCOS
ABSTRACT Objective: A disintegrin and metalloproteinase with thrombospondin motifs 4 (ADAMTS-4) and ADAMTS-5 normal expression levels are essential for ovulation and subsequent fertilization. The objective of the present study was to assess expression pattern of these genes in cumulus cells (CCs) taken from patients with polycystic ovary syndrome (PCOS) and

2. Cell migration inhibition activity of a non-RGD disintegrin from Crotalus durissus collilineatus venom
Abstract Background: In recent decades, snake venom disintegrins have received special attention due to their potential use in anticancer therapy. Disintegrins are small and cysteine-rich proteins present in snake venoms and can interact with specific integrins to inhibit their activities in cell-cell and cell-ECM interactions. These molecules, known to inh

3. Alternagin-C binding to α2β1 integrin controls matrix metalloprotease-9 and matrix metalloprotease-2 in breast tumor cells and endothelial cells
Abstract Background Matrix metalloproteinases (MMPs) are key players in tumor progression, helping tumor cells to modify their microenvironment, which allows cell migration to secondary sites. The role of integrins, adhesion receptors that connect cells to the extracellular matrix, in MMP expression and activity has been previously suggested. However, the m

4. Effects of blocking αvβ3 integrin by a recombinant RGD disintegrin on remodeling of wound healing after induction of incisional hernia in rats
PURPOSE: To investigate the changes induced by DisBa-01 on repair of wound healing after induced incisional hernia (IH) in rats. METHODS: Thirty two male albino rats were submitted to IH and divided into four experimental groups: G1, placebo control; G2, DisBa-01-treated; G3, anti-αvβ3 antibodies-treated and G4, anti-α2 antibodies-treated. Histological,

5. Effects of Blocking αvβ3 integrin by a recombinant RGD disintegrin on remodeling of wound healing after induction of incisional hernia in rats
PURPOSE: Incisional hernia (IH) is characterized by defective wound healing process. Disba-01, a αvb3 integrin blocker has shown to control the rate of wound repair and therefore it could be a target for new wound healing therapies.The objective of the study was to determine the changes induced by Disba-01 on repair of wound healing after induced IH in rat

6. FUNCTIONAL PROTEOMICS OF CIRRHOSIS AND HEPATOCELLULAR CARCINOMA / ProteÃmica Funcional da Cirrose e do Carcinoma Hepatocelular
Introduction. Cancer is the most common given name to a series of molecular and physiological events which result in genetic instability and biochemical imbalance in cells. Among the seven events that drives cell cancer, the role of chronic inflammation and tumor microenvironment in cancer development were highlighted in this work . To experimentally evaluat

7. Tumor cytotoxicity of leucurolysin-B, a P-III snake venom metalloproteinase from Bothrops leucurus
Although it has been demonstrated that venoms and toxins from some snakes are able to influence the growth of tumor cells, few antitumoral compounds from Bothrops leucurus venom have been characterized. Leucurolysin-B (leuc-B) is a metalloproteinase class P-III isolated from B. leucurus which possesses an ECD-disintegrin domain. Both ECD-disentegrin and RGD-

8. Efeitos de uma desintegrina RGD recombinante de Rhinocerophis alternatus (Bothrops alternatus) na migração de células normais e tumorais
Cell migration, invasion of the surrounding tissues, blood vessels and proliferation are cellular processes involved in metastases. These events are mediated by integrins, adhesion receptors present on cell surfaces and responsible for the extracellular matrix and cells binding. Disintegrins, snake venoms polypeptides, are known to inhibit integrins action,

9. Produção recombinante e caracterização de uma desintegrina da peçonha de Rhinocerophis alternatus (antiga Bothrops alternatus) com atividade antimetastática visando o desenvolvimento de um novo fármaco
This work presents the study of the effects of an RGD disintegrin from Rhinocerophis alternatus (ancient Bothrops alternatus) in key steps of the metastatic cascade. Disintegrins are cysteine-rich peptides, which have several biological activities related to cell-cell interaction and cell adhesion. The correct pairing of disulfide bonds exposes the adhesive

10. Papel do domínio desintegrina da ADAM9 humana na modulação da migração e invasão de células tumorais
A metástase é a maior causa de morte no câncer, desta forma estudos que visam compreender os mecanismos nela envolvidos são importantes para o entendimento deste processo. A migração e invasão celular participam do processo metastático, portanto, estudos de moléculas que impeçam a migração podem fornecer as bases para o desenvolvimento de fármac

11. ALT-C, a disintegrin-like Cys-rich protein from Bothrops alternatus, increases skeletal myoblast viability
ALT-C, an ECD motif (glutamic acid, cysteine, aspartic acid) disintegrin from Bothrops alternatus snake venom, induces α2β1 integrin-mediated signaling and neutrophil chemotaxis. In vitro, in human umbilical vein endothelial cells (HUVEC), ALT-C induces cell proliferation, thus showing an interesting potential for tissue regeneration studies. This work aim

12. Biochemical and biophysical studies of metalloproteinases/disintegrins from snake venom / Estudos bioquímicos e biofísicos de metaloproteinases/desintegrinas de venenos de serpentes
Metalloproteinases/disintegrin (MD) isolated from snake venom are potent inhibitors of platelet aggregation and cell adhesion, processes involved in illnesses as cancer and thrombosis. MD belong to the PIII class of the metalloproteinase/disintegrin gene family and they are constituted by three domains: the catalytic domain, metalloprotease; disintegrin-like
