1. Plant senescence and proteolysis: two processes with one destiny
Abstract Senescence-associated proteolysis in plants is a complex and controlled process, essential for mobilization of nutrients from old or stressed tissues, mainly leaves, to growing or sink organs. Protein breakdown in senescing leaves involves many plastidial and nuclear proteases, regulators, different subcellular locations and dynamic protein traffic

2. Produção recombinante e caracterização funcional de uma legumaína de cana-de-açúcar
Plant legumains, also termed vacuolar processing enzymes (VPEs), are cysteine peptidases that play key roles in seed maturation, germination, senescence, stress response, programmed cell death during development and defense against pathogens. Despite the increasing number of reports on VPEs, most of studies are on dicotyledonous legumain and their role in se

4. Theobroma cacao cystatins impair Moniliophthora perniciosa mycelial growth and are involved in postponing cell death symptoms.
Three cystatin open reading frames named TcCys1, TcCys2 and TcCys3 were identified in cDNA libraries from compatible interactions between Theobroma cacao (cacao) and Moniliophthora perniciosa. In addition, an ORF named TcCys4 was identified in the cDNA library of the incompatible interaction. The cDNAs encoded conceptual proteins with 209, 127, 124, and 205

5. Cystatin C serum levels in term newborns along the neonatal period / Evolução dos níveis séricos de cistatina C em recém-nascidos de termo no primeiro mês de vida
INTRODUÇÃO: A cistatina C sérica apresenta boa correlação com o ritmo de filtração glomerular (RFG) e não é influenciada pela função renal materna, podendo ser um bom marcador da função renal, especialmente na 1ª semana de vida. Porém, não há valores normais definidos para o período neonatal. OBJETIVO: Determinar a evolução dos níveis s�

6. Produção recombinante e estudos funcionais de três novas cistatinas da cana-de-açúcar e sua utilização em estudos de inibição da adesão, proliferação, migração e invasão celular
ABSTRACT Tumor metastasis is usually a major cause of death among cancer patients. Degradation and invasion of the extracellular matrix and basement membrane, key steps in the metastatic process, rely on the activity of proteolytic enzymes. The levels and activities of cathepsins B and L are considerably increased in cancer cells, and have been related to th

7. Validação do método imunonefelométrico para dosagem de cistatina C, como marcador de função renal / Validation of cystatin C measurement by particle-enhanced immunonephelometry as renal function marker
A cistatina C sérica tem sido apontada como um marcador de filtração glomerular. Neste trabalho realizamos a validação de um método específico e automatizado, a imunonefelometria, mensurando os níveis séricos de cistatina C através do nefelômetro da empresa Behring (BN II). O ensaio perfaz o intervalo de referência de 0.23-7.25 mg/L, até sete ve

8. Avaliação da dosagem sérica de cistatina C para detecção precoce de alterações na função do enxerto após o transplante renal / Evaluation of the serum concentration of cystatin C to early detection changes in graft function after kidney transplantation
INTRODUCTION: Cystatin C is a nonglycosylated protein that is synthesized by all nucleated cells. The present study aimed to analyze the accuracy of serum concentration of cystatin C for detecting longitudinal change in glomerular filtration rate in transplanted recipients, as well to define a better methodological strategy to perform the plasma clearance of

9. Identificação e caracterização de proteinas expressas no espaço intercelular de folhas de Theobroma cacao na interação com Moniliophthora perniciosa / Identification and characterization of proteins expressed in the intercellular space of leves from Theobroma cacao infected by Moniliophthora perniciosa
The invasion of the plant apoplast is a critical phase of the infection for numerous pathogens, including the fungus M. perniciosa (Mp) that remains in the intercellular space at the parasitic stage until about 60 days. Thus, the understanding of plant defenses induced in the apoplasm and the response mechanisms that the pathogens used for bypassing these de

10. Expressão recombinante da canacistatina em células de inseto.
Due to the great economic importance of sugarcane crop in Brazil, the occurrence of infections by phytopathogens leading to decreased productivity and quality remains a serious problem. As the plants have natural mechanisms of defense against the attack of fungi and insects, amongst which the inhibitors of proteases are distinguished, the use of these substa

11. Cysteine proteinases and cystatins
Nesta revisão foram descritas definições, localizações, funções e exemplos de proteinases cisteínicas e suas proteinas inibidoras em animais vertebrados e invertebrados e plantas. Tratamos principalmente com aqueles inibidores que são relatados com o mecanismo de defesa da planta contra pestes. Em adição, comentamos sobre recentes trabalhos que co

12. Parasite-Specific Immunomodulatory Functions of Filarial Cystatin
Cystatins of parasitic nematodes are well-described pathogenicity factors which contribute to downregulation of T-cell proliferation of their hosts and induce anti-inflammatory cytokine responses. We compared the immunomodulatory effects of two cystatins of the filarial nematodes Onchocerca volvulus and Acanthocheilonema viteae with two homologous proteins o
