1. BthTX-I from Bothrops jararacussu induces apoptosis in human breast cancer cell lines and decreases cancer stem cell subpopulation
ABSTRACT Background: Breast cancer is the neoplasm with both the highest incidence and mortality rate among women worldwide. Given the known snake venom cytotoxicity towards several tumor types, we evaluated the effects of BthTX-I from Bothrops jararacussu on MCF7, SKBR3, and MDAMB231 breast cancer cell lines. Methods: BthTX-I cytotoxicity was determined

2. Kaempferol suppresses human gastric cancer SNU-216 cell proliferation, promotes cell autophagy, but has no influence on cell apoptosis
Gastric cancer remains a serious threat to human health worldwide. Kaempferol is a plant-derived flavonoid compound with a wide range of pharmacological activities. This study aimed to investigate the effects of kaempferol on gastric cancer SNU-216 cell proliferation, apoptosis, and autophagy, as well as underlying potential mechanisms. Viability, proliferat

4. Impact of extracellular alkalinization on the survival of human CD24-/CD44+ breast cancer stem cells associated with cellular metabolic shifts
Cancer stem cells reside in a distinct region within the tumor microenvironment that it is believed to play a fundamental role in regulating stemness, proliferation, survival, and metabolism of cancer cells. This study aimed to analyze the effect of extracellular alkalinization on metabolism and survival of human CD24-/CD44+ breast cancer stem cells (BCSCs).

5. Lithium carbonate and coenzyme Q10 reduce cell death in a cell model of Machado-Joseph disease
Machado-Joseph disease (MJD) or spinocerebellar ataxia type 3 (SCA3) is an autosomal dominant neurodegenerative disorder caused by expansion of the polyglutamine domain of the ataxin-3 (ATX3) protein. MJD/SCA3 is the most frequent autosomal dominant ataxia in many countries. The mechanism underlying MJD/SCA3 is thought to be mainly related to protein misfold

6. Differential gene expressions of the MAPK signaling pathway in enterovirus 71-infected rhabdomyosarcoma cells
BACKGROUND: Mitogen-activated protein kinase (MAPK) signaling pathway plays an important role in response to viral infection. The aim of this study was to explore the function and mechanism of MAPK signaling pathway in enterovirus 71 (EV71) infection of human rhabdomyosarcoma (RD) cells. METHODS: Apoptosis of RD cells was observed using annexin V-FITC/PI bin

7. Mecanismos de proteção da distrofia muscular : estudo proteômico e terapia farmacológica / Protective mechanisms of muscular dystrophy : proteomic study and pharmacological therapy
In Duchenne Muscular Dystrophy (DMD) and in the mdx mice model of DMD, the lack of dystrophin leads to muscle degeneration. The pathogenesis of DMD is related to sarcolemmal fragility, mechanical stress and increased influx of calcium in muscle fibers, due to dysfunction of ion channels, such as the stretch-activated calcium channels. The knowledge of the pr

8. Atividade imunomoduladora da ouabaína no processo inflamatório agudo / OUABAIN IMMUNOMODULATORY ACTIVITY IN THE ACUTE INFLAMMATORY PROCESS.
Ouabain (OUA), a potent inhibitor of the Na+,K+-ATPase pump, was identified as an endogenous substance of human plasma. In recent years, ouabain was shown to affect various immunological processes. Mechanisms that involve cellular differentiation, proliferation, activation and migration, as well as inflammatory mediators release, are activated during inflamm

9. Quantification of autoantibodies to annexin V in plasma by an "in house" sandwich ELISA
Foi desenvolvido e validado um ELISA tipo sanduíche "in house" para a quantificação de anticorpos (Ac) anti-anexina V em plasma. Os parâmetros de validação estudados foram: (i) precisão, expressado como coeficiente de variação (CV) inter- e intra-ensaio, (ii) exatidão, expressado como porcentagem de desvio entre o valor obtido e o valor real, (iii)

10. Novos biomarcadores para o diagnóstico não invasivo do carcinoma oral de células escamosas
CAPÍTULO I: A detecção precoce do carcinoma oral de céulas escamosas (OSCC) é fator importante na diminuição das taxas de mortalidade e o sucesso do tratamento relaciona-se diretamente com seu diagnóstico em fases iniciais. Contudo, infelizmente, a maioria dos carcinomas orais é diagnosticada em fases tardias da doença. No presente trabalho, pela p

11. Protein decorated Nanoparticules : Small Unilamellar Lipid Vesicules and Block Copolymers Micelles. / Nanoparticules Décorées par des Protéines : Vésicules Lipidiques Unilamellaires et Micelies à Base de Copolymères à Blocs
The formation of protein Annexin-A5 decorated (bio-functionalized) nanoparticles is of particular interest in micelle-mediated target drug delivery, in vivo magnetic resonance imaging, or controlled fabrication of biochips. This work describes an easy access to the synthesis and manipulation of block copolymer nano-objects exhibiting binding ability for the

12. Caracterização da DNase da peçonha da serpente Bothrops alternatus : comparação com a DNase acida de mamiferos envolvida em apoptose / Characterization of a Dnase from Bothrops alternatus snake venom : comparision with mamalian acid Dnases involved in apoptosis
Bothrops snake venoms are cytotoxic to a variety of cells (endothelial, smooth muscle, renal and inflammatory cells), and may cause cell death by apoptosis. The venom components implicated in apoptosis include metalloproteinases and L-amino acid oxidase. In contrast, although acidic deoxyribonucleases (DNase II) have been implicated in DNA fragmentation duri
