1. An early stage in T4-induced hyperthyroidism is related to systemic oxidative stress but does not influence the pentose cycle in erythrocytes and systemic inflammatory status
ABSTRACT Objective Hyperthyroidism causes many injuries in its target organs and the consequences are reflected systemically. As systemic alterations in hyperthyroidism at earlier stages have received partial attention, this study aimed to investigate systemic redox and inflammatory status at an early stage of T4-induced hyperthyroidism. Materials and met

2. Expression, Purification and Functional Assessment of Smallest Isoform of Human Interleukin-24 in Escherichia coli
ABSTRACT Interleukin-24 (IL-24) is a novel tumor-suppressor gene that has different alternative splice isoforms. It has been shown that new smallest isoform of human IL-24 gene, lacking three exons, induces higher levels of cytotoxicity than all the isoforms, indicating shortest isoform of IL-24 may be a new promising anti-cancer agent. In this study, we aim

3. Dexmedetomidine protects against renal ischemia and reperfusion injury by inhibiting the P38-MAPK/TXNIP signaling activation in streptozotocin induced diabetic rats
Abstract Purpose: To determine whether dexmedetomidine (DEX) could attenuate acute kidney injury (AKI) induced by ischemia/reperfusion (I/R) in streptozotocin (STZ)-induced diabetic rats. Methods: Four groups each containing six rats were created (sham control(S), diabetes-sham (DS), diabetes I/R (DI/R), and diabetes-I/R-dexmedetomidine (DI/R-DEX). In diab

4. Polimorfismos nos genes que codificam a glutationa peroxidase-4, a tiorredoxina e a proteína de interação com a tiorredoxina modulam a susceptibilidade à doença renal em portadores de diabetes mellitus tipo 1 / Polymorphisms in the genes coding for glutathione peroxidase-4, thioredoxin and thioredoxin interaction protein modulate the risk for renal disease in type 1 diabetes patients
INTRODUÇÃO: evidências sugerem a participação de fatores genéticos na susceptibilidade para o desenvolvimento das complicações renais em pacientes portadores de diabetes mellitus tipo 1 (DM1). Vários genes relacionados às vias bioquímicas induzidas pela hiperglicemia têm sido investigados e o estresse oxidativo foi reconhecido como o principal me

5. Transcriptome analysis of resistant soybean roots infected by Meloidogyne javanica
Soybean is an important crop for Brazilian agribusiness. However, many factors can limit its production, especially root-knot nematode infection. Studies on the mechanisms employed by the resistant soybean genotypes to prevent infection by these nematodes are of great interest for breeders. For these reasons, the aim of this work is to characterize the trans

6. Estudo de interações proteicas da Tiorredoxina Peroxidase Nuclear (nTPx) de Sacharomyces cerevisiae nos eventos de crescimento celular e silenciamento telomérico
As tiorredoxinas peroxidases (TPx), constituem um grupo de proteínas antioxidantes que vêm sendo bastante estudadas pela sua atuação na decomposição de diversos tipos peróxidos, como o H2O2, peroxinitritos e peróxidos orgânicos. A capacidade de decomposição de peróxidos pelas TPx está relacionada a presença de uma cisteína conservada denominad

7. Analysis of the stress-inducible transcription factor SsNAC23 in sugarcane plants
Stresses such as cold and drought can impair plant yield and induce a highly complex array of responses. Sugarcane (Saccharum spp.) is cultivated in tropical and subtropical areas and is considered a cold-sensitive plant. We previously showed that cold stress induces the expression of several genes in in vitro sugarcane plantlets. Here we characterize one of

8. Identificação de interatores putativos envolvidos na localização de proteínas de duplo direcionamento em Arabidopsis thaliana / Identification of putative interactors involved in the localization of dual-targeted proteins in Arabidopsis thaliana
Most organellar proteins are nuclear encoded, synthesized in the cytosol and then targeted to their destination. Specific subcellular targeting is conducted by a complex machinery for the specific localization of the proteins, which includes targeting sequences, cytosolic proteins and specific organelar receptors. However, little is known about the process t

9. Clonagem e expressão do gene da tiorredoxina 1 de Paracoccidioides brasiliensis em Pichia pastoris / Cloning and expression of the thioredoxin 1 gene of Paracoccidioides brasiliensis in pichia pastoris
The termodimorphic fungus Paracoccidioides brasiliensis is the etiological agent of paracoccidioidomycosis, a human systemic mycosis of high prevalence in Latin America. P. brasiliensis is exposed to oxidative stress (OS) caused by reactive oxygen species (ROS) produced by the defense cells of the human host. When the invasion by pathogens occurs, the host d

10. Mechanisms of methilmercury toxicity: protective effect of flavonoids / ESTUDO DE MECANISMOS DE TOXICIDADE DO METILMERCÚRIO: PAPEL PROTETOR DE FLAVONÓIDES
O metilmercúrio (MeHg) é um importante agente tóxico ambiental que pode causar desordens neurocomportamentais e neurofisiológicas irreversíveis em humanos e animais experimentais. Os principais mecanismos pelos quais o MeHg induz toxicidade são: a ruptura na homeostase do cálcio intracelular, a indução de estresse oxidativo, a inibição da atividad

11. Structural studies of the proteins Q4DV70 from Trypanosoma cruzi and mesothelin from Homo sapiens / Estudos estruturais das proteinas Q4DV70 de Trypanosoma cruzi e mesotelina de Homo sapiens
In this work we carried out studies with two proteins, Q4DV70 from Trypanosoma cruzi and mesothelin from Homo sapiens. The aim was to help the understanding of the function of these proteins which possibly are important to Chagas disease and cancer, respectively. Q4DV70 protein was annotated in T. cruzi genome as a conserved hypothetical protein. In our stud

12. Interações de peroxirredoxinas citossólicas da levedura Saccharomyces cerevisiae com peróxidos. Estudos cinéticos e funcionais / Saccharomyces cerevisiae cytosolic peroxiredoxin interactions with peroxides. Kinetics and functional studies
Peroxiredoxins constitute a family of cysteine-based peroxidases that are able to reduce hydrogen peroxide, organic peroxides and peroxinitrite to water, alcohol and nitrite, respectively, through the use of reducing equivalents provided by thioredoxin, thioredoxin reductase and NADPH. Peroxiredoxins are abundant enzymes (correspond to approximately 0.7% of
