1. Genome-wide identification, characterisation and expression profiling of the ubiquitin-proteasome genes in Biomphalaria glabrata
BACKGROUND Biomphalaria glabrata is the major species used for the study of schistosomiasis-related parasite-host relationships, and understanding its gene regulation may aid in this endeavor. The ubiquitin-proteasome system (UPS) performs post-translational regulation in order to maintain cellular protein homeostasis and is related to several mechanisms, i

2. New proteasome inhibitors in the treatment of multiple myeloma
Abstract The treatment of patients with relapsed and/or refractory multiple myeloma has improved considerably in the last 15 years, after the introduction of proteasome inhibitors and immunomodulatory drugs. The first clinical trials with new proteasome inhibitors have produced exciting results, particularly those comparing triplet regimens with standard dou

3. Myostatin promotes distinct responses on protein metabolism of skeletal and cardiac muscle fibers of rodents
Myostatin is a novel negative regulator of skeletal muscle mass. Myostatin expression is also found in heart in a much less extent, but it can be upregulated in pathological conditions, such as heart failure. Myostatin may be involved in inhibiting protein synthesis and/or increasing protein degradation in skeletal and cardiac muscles. Herein, we used cell c

4. Plant arginyltransferases (ATEs)
Abstract Regulation of protein stability and/or degradation of misfolded and damaged proteins are essential cellular processes. A part of this regulation is mediated by the so-called N-end rule proteolytic pathway, which, in concert with the ubiquitin proteasome system (UPS), drives protein degradation depending on the N-terminal amino acid sequence. One imp

5. Conservation and developmental expression of ubiquitin isopeptidases in Schistosoma mansoni
Several genes related to the ubiquitin (Ub)-proteasome pathway, including those coding for proteasome subunits and conjugation enzymes, are differentially expressed during the Schistosoma mansoni life cycle. Although deubiquitinating enzymes have been reported to be negative regulators of protein ubiquitination and shown to play an important role in Ub-depen

6. Caracterização de putativo receptor serpentino e estudos sobre a implicação do sistema de ubiquitina/proteossomo na modulação do ciclo celular de Plasmodium falciparum. / Caracterization of serpentine receptor putative and studies about the implication of ubiquitin/proteasome system in Plasmodium falciparum cell cycle.
É proposto que vias de sinalização controlem a sobrevivência e adaptação do Plasmodium, nos diferentes hospedeiros. No presente trabalho buscamos por diferentes abordagens estudar a via de sinalização de melatonina em P. falciparum. Para isso, avaliamos os níveis de RNA mensageiro de genes do sistema-ubiquitina proteossomo (UPS) bem como o perfil de

7. Modulação do metabolismo muscular em camundongos exercitados e suplementados com leucina / Modulation of muscle metabolism by exercise and leucine supplementation in mice
We investigated the effects of chronic physical training, associated or not with leucine supplementation, on protein and glucose metabolism in soleus muscle of Swiss mice. Half of the mice (T) performed a 12 weeks protocol of swimming exercise, 1h/day, 5 days/week, bearing no overload, and the other half remained sedentary (C). Additionally, half of the C an

8. REGγ is a strong candidate for the regulation of cell cycle, proliferation and the invasion by poorly differentiated thyroid carcinoma cells
REGγ is a proteasome activator that facilitates the degradation of small peptides. Abnormally high expression of REGγ has been observed in thyroid carcinomas. The purpose of the present study was to explore the role of REGγ in poorly differentiated thyroid carcinoma (PDTC). For this purpose, small interfering RNA (siRNA) was introduced to down-regulate th

9. Comparative proteomics analysis of chronic atrophic gastritis: changes of protein expression in chronic atrophic gastritis without Helicobacter pylori infection
Chronic atrophic gastritis (CAG) is a very common gastritis and one of the major precursor lesions of gastric cancer, one of the most common cancers worldwide. The molecular mechanism underlying CAG is unclear, but its elucidation is essential for the prevention and early detection of gastric cancer and appropriate intervention. A combination of two-dimensio

10. Efeito da transecção do ligamento cruzado anterior na expressão de genes de atrofia no músculo quadríceps de ratos
A atrofia e fraqueza do quadríceps após a ruptura do ligamento cruzado anterior (LCA), presentes antes e após sua reconstrução, são importantes limitações que restringem o retorno dos indivíduos às atividades da vida diária e desportivas. A rápida proteólise muscular que ocorre nos diversos modelos animais e em diferentes condições em humanos

12. Análise de Marcadores Gênicos de Estresse Genotóxico em Fibroblastos Humanos Normais e Células de Glioblastoma. / Analysis of Gene Markers of Genotoxic Stress in Human Normal Fibroblasts and Glioblastoma Cells.
Muitos genes têm sido indicados como responsivos ao estresse genotóxico, mas devido à necessidade de validação, a busca por marcadores gênicos continua. Vários genes são relacionados ao sistema ubiquitina-proteassomo (UPS), o qual é responsável pela remoção seletiva de proteínas, sendo que falhas no UPS têm sido relacionadas a doenças neurodeg
