13. Ischemia preconditioning is neuroprotective in a rat cerebral ischemic injury model through autophagy activation and apoptosis inhibition
Sublethal ischemic preconditioning (IPC) is a powerful inducer of ischemic brain tolerance. However, its underlying mechanisms are still not well understood. In this study, we chose four different IPC paradigms, namely 5 min (5 min duration), 5×5 min (5 min duration, 2 episodes, 15-min interval), 5×5×5 min (5 min duration, 3 episodes, 15-min intervals), a

14. Análise de custo-efetividade dos inibidores da rapamicina para o tratamento de imunossupressão no transplante renal
Terminal chronic kidney disease can be treated with hemodialysis (HD), peritoneal dialysis (PD) or by means of renal transplantation. Among these three treatment modalities, the transplant is, according to the literature, the modality that offers better quality of life. Adding to this the progress of the immunosuppressants used in post-transplant, the number

15. A participação da proteína cinase mTOR (mammalian target of rapamycin) e do fator transcricional NF-kB na regulação da expressão do GLUT4 em músculo sóleo de ratos. / The participation of protein kinase mTOR (mammalian target of rapamycin) and the transcriptional factor NF-kB in regulating the expression of GLUT4 in soleus muscle of rats.
A insulina regula a expressão de GLUT4, porém os mecanismos envolvidos nesta regulação não estão definidos. Alguns fatores de transcrição e proteínas cinases estão relacionados com a expressão de GLUT4. Assim, o objetivo desta pesquisa foi investigar a participação dos fatores de transcrição MEF2, HIF-1a e NF-

16. Salmonella enterica serovar Typhi plasmid pR ST98 enhances intracellular bacterial growth and S. typhi-induced macrophage cell death by suppressing autophagy
OBJECTIVES: Plasmid pR ST98 is a hybrid resistance-virulence plasmid isolated from Salmonella enterica serovar Typhi (S. typhi). Previous studies demonstrated that pR ST98 could enhance the virulence of its host bacteria. However, the mechanism of pR ST98-increased bacterial virulence is still not fully elucidated. This study was designed to gain further ins

17. Localização genômica e subcelular dos membros da família de fosfatidilinositol quinases em Trypanosoma cruzi / Genomic and subcellular localization of the members of phosphatidylinositol kinase family in Trypanosoma cruzi
The identification of signaling molecules and the elucidation of signal transduction processes of Trypanosoma cruzi are required for understanding the host-parasite interaction and physiological processes of the parasite. However, little is yet known about signal transduction and signaling pathways that occur in the parasite, since most efforts focused on si

18. Molecular and cellular pathogenesis of autosomal dominant polycystic kidney disease
Autosomal dominant polycystic kidney disease (ADPKD) is one of the most common human life-threatening monogenic disorders. The disease is characterized by bilateral, progressive renal cystogenesis and cyst and kidney enlargement, often leading to end-stage renal disease, and may include extrarenal manifestations. ADPKD is caused by mutation in one of two gen

19. Análise do perfil de expressão gênica de linhagens epiteliais mamárias humanas submetidas ao tratamento com rapamicina associada à doxorrubicina / Gene expression analysis of human breast epithelial cell lines treated with the combination of rapamycin and doxorubicin
A resistência à quimioterapia, a qual se constitui em um dos maiores desafios a serem superados durante o tratamento do cancer de mama, pode ser modulada por várias cascatas de sinalização cellular que levam ao aumento da sobrevivência celular. A via PI3K/Akt/mTOR é uma importante reguladora desse processo, visto que ela pode favorecer o crescimento t

20. Proteínas quinases envolvidas na regulação do estresse em Trypanosoma. / Protein kinases involved in stress regulation in Trypanosoma.
Protozoa of the genus Trypanosoma have a complex life cycle alternating between vertebrate and invertebrate hosts. The adaptation to different environmental conditions requires rapid changes in gene expression to fill up the morphological and metabolic requirements for survival. Very little is known about the mechanisms that control these changes and the sig

21. Effect of tyrosine phosphatase Shp2 silencing on phenotypic changes of cardiomycytes and effect of mutations and deletion of Shp2 in the hearts of mjice subjected to mechanical stress / Efeito do silenciamento da tirosino-fosfatase Shp2 nas alterações fenotípicas dos miócitos cardíacos e efeito da deleção e mutações da Shp2 em corações de camundongos submetidos ao estresse mecânico
Estudos do nosso laboratório demonstraram que a quinase de adesão focal (FAK) é ativada e contribui para a regulação dos mecanismos de sinalização que determinam as alterações fenotípicas de cardiomiócitos submetidos a estímulos mecânicos. Em estudo anterior demonstramos através da inibição farmacológica da Shp2, que a mesma contribui para a

22. Oral rapamycin attenuates atherosclerosis without affecting the arterial responsiveness of resistance vessels in apolipoprotein E-deficient mice
The objective of the present study was to assess the effects of the immunosuppressant rapamycin (Rapamune®, Sirolimus) on both resistance vessel responsiveness and atherosclerosis in apolipoprotein E-deficient 8-week-old male mice fed a normal rodent diet. Norepinephrine (NE)-induced vasoconstriction, acetylcholine (ACh)- and sodium nitroprusside (SNP)-indu

The goal of this work was to contribute to a better understanding about the intracellular mechanisms involved in skeletal muscle regeneration by studying the influence of heat shock proteins (HSPs) and mTORC1 (mammalian target of rapamycin complex 1) in the muscle regeneration process. The treatment with radicicol (a HSP inductor) in injured muscles induced

24. IRS-1 influence in prostate neoplasm / Papel do IRS-1 no desenvolvimento do cancer de prostata
A regulação adequada da via de sinalização PI 3-quinase-Akt é essencial para a prevenção da carcinogênese. Dados recentes caracterizaram uma alça de retroalimentação negativa na qual a mammalian target of rapamycin (mTOR), bloqueia a ativação adicional da via Akt/mTOR por meio da inibição da função do substrato 1 do receptor de insulina (IRS
