Abstract:

Introdução: A hipertrofia cardíaca induzida por sobrecarga hemodinâmica crônica (HC) é caracterizada por espessamento das paredes do ventrículo esquerdo e do tecido intersticial. As atividades aumentadas de calpaína-1 e metaloproteinase de matriz(MMP)-2 são observadas em diferentes modelos de hipertensão arterial e estão relacionadas com as mudanças fisiopatológicas na HC. Por outro lado, a atividade de MMP-2 parece ser modulada positivamente por ativação de calpaína-1 em diferentes modelos. O objetivo deste trabalho é analizar se a calpaína-1 contribui para o aumento da atividade de MMP-2 no

Abstract:

Dengue virus (DENV) is an arthropod-borne virus and has become a worldwide problem with steadily rising annual infection rates. Patients present with a range of symptoms from mild fever to, in some cases, life-threatening hemorrhagic fever and shock syndrome. The most severe cases require emergency hospital care and currently, there is no effective drug treatment or vaccine for dengue. As severe symptoms appear post-peak viremia, immuno-pathology is thought to be the cause and a potential trigger of this is differential activation of the immune response upon recognition of DENV. This could be

Abstract:

La spasticité et la douleur neuropathique sont deux symptômes apparaissant fréquemment après une lésion médullaire. La spasticité est définie comme une augmentation du tonus musculaire qui provoque des contractures, tandis que la douleur neuropathique se caractérise par des sensations douloureuses survenant suite à une lésion du système nerveux.Ces deux symptômes résultent en partie d’une désinhibition des réseaux neuronaux sous-lésionnels lié à une diminution de l’expression du cotransporteur potassium-chlorure type 2 (KCC2). Pour être efficace,l’inhibition nécessite l’action de cette protéin

Abstract:

The lens of the eye needs to be completely transparent in order to allow all light entering the eye to reach the retina. This transparency is maintained by the highly ordered structure of the lens proteins the crystallins. Any disruption to the lens proteins can cause an opacity to develop which is known as cataract. During cortical cataract formation there is increased truncation of the lens crystallins. It is believed that overactivation of calcium-dependent cysteine proteases, the calpains, is responsible for the increased proteolysis of the crystallins seen during cataractogenesis. Within

La calpaïne 1 est une protéase à cystéine activée par le calcium, qui peut être partiellement externalisée. Les calpaines extracellulaires favorisent la résolution de l'inflammation et la réparation des tissus, à travers la prolifération et la migration cellulaire. Le récepteur Toll like (TLR) 2 a été identifié comme une cible des calpaïnes extracellulaires dans les lymphocytes. L'objectif est d'étudier le rôle de la calpaïne extracellulaire 1 dans la progression tumorale de l'adénocarcinome pulmonaire lepidique (ADL).

Abstract:

Calpains are a family of intracellular cysteine proteases activated by calcium. They participate in many processes including cell motility, cell cycle progression and cell death, in response to calcium signaling. Because calpain over-activation as a result of calcium dysregulation is a contributing factor to many disease states, these enzymes are important therapeutic targets. Within the cell, calpains 1 and 2 are regulated by the protein inhibitor calpastatin. This unstructured protein is specific for calpain, binds tightly, and recognizes only the activated form of the enzyme. Detailed

Abstract:

Glioblastoma is the most malignant primary brain tumor with the average patients surviving only one year after diagnosis, even with aggressive therapy. The formation of numerous micro-tumors dispersed into the brain due to rapid invasion of tumor cells, presents the primary challenge to the surgical removal of tumors and limits the effectiveness of current treatments. This dissertation presents studies aimed at understanding the molecular mechanisms regulating invasion of human glioblastoma cells. Transplantation of human glioblastoma cells in the zebrafish brain showed that the knockdown of c

Abstract:

Calpains are calcium-dependent, intracellular, multi-domain cysteine proteases involved in many physiological functions regulated by calcium signaling, including cell motility. How calpains are activated in the cell is still unknown because the resting intracellular concentration of Ca2+ is orders of magnitude lower than that needed for half-maximal activation of the enzyme in vitro. Several stratagems by which calpains might overcome this Ca2+ concentration differential have been proposed. It is possible that post-translational modifications like phosphorylation, or accessory proteins tha

Abstract:

Type 2 diabetes is characterized by an inability to maintain normoglycemia due to impairments in both insulin secretion and action. The impaired capacity of the pancreatic beta cell to secrete sufficient concentrations of insulin directly contributes to the worsening glycemic control. High concentrations of glucose and free fatty acids have been shown to be deleterious for pancreatic beta cell function and viability. Increased availability of glucose and free fatty acids may also contribute to the aggregation of islet amyloid polypeptide (IAPP) and formation of islet amyloid, a commonly observ

Abstract:

α-actinin-4 is a non-muscle isoform of α-actinin that belongs to the spectrin superfamily. It comprises three functional regions: an N-terminal actin-binding region that consists of two calponin homology (CH) domains, a central region that consists of four copies of the spectrin-like repeat domain and a C-terminal calmodulin-like domain that is predicted to bind Ca²⁺. α-actinin-4 is organised as an antiparallel homodimer formed by the interaction of four spectrin-like repeats between the two monomers, giving a rod-like shape, with actin binding regions at both ends. α-actinin-4 is an abundant
