Vitamina D, miR-21 y marcadores de apoptosis en pacientes con diabetes tipo I

La diabetes Tipo 1 (DT1) es una compleja enfermedad autoinmune con una etiología aún desconocida. La vitamina D ha sido ampliamente estudiada debido a su potencial terapéutico en los potenciales nuevos casos de DT1. Por otra parte, los microARNs (miRs) han sido propuestos como posibles biomarcadores e...

Policistina-1 protege a los cardiomiocitos de la necrosis inducida por estrés mecánico

Rev. chil. cardiol; 38 (1), 2019
Resumen: Antecedentes: La muerte de los cardiomiocitos es determinante en el desarrollo de patologías cardiacas posteriores al infarto del miocardio y la insuficiencia cardiaca. Las variaciones en la expresión de la familia de proteínas BCL-2 regulan vías, tanto de muerte, como de sobrevida celular...

Gramicidin inhibits human gastric cancer cell proliferation, cell cycle and induced apoptosis

Biol. Res; 52 (), 2019
BACKGROUND: Gastric cancer is a common malignant tumor with high morbidity and mortality worldwide, which seriously affects human health. Gramicidin is a short peptide antibiotic which could be used for treating infection induced by bacteria or fungi. However, the anti-cancer effect of gramicidin on gast...

The role of the exogenous supply of adenosine triphosphate in the expression of Bax and Bcl2L1 genes in intestinal ischemia and reperfusion in rats

Acta cir. bras; 33 (10), 2018
Abstract Purpose: To investigate the role of the exogenous supply of adenosine triphosphate (ATP) in the expression of Bax and Bcl2L1 genes in intestinal ischemia and reperfusion (IR) in rats. Methods: The study was designed as a randomized controlled trial with a blinded assessment of the outcome. Eig...

High expression of XIAP and Bcl-2 may inhibit programmed cell death in glioblastomas

Arq. neuropsiquiatr; 75 (12), 2017
ABSTRACT Glioblastoma (GBM) is the most malignant glioma and represents 29% of all brain tumors. Tumorigenesis is intimately connected with characteristics acquired in the physiologic pathway of cellular death. Objective: In the present study, the expression of anti-apoptotic (XIAP and Bcl-2) and apopto...

Myocardial ischemic post-conditioning protects the lung against myocardial ischemia/reperfusion-induced damage by activating GSK-3

Acta cir. bras; 32 (5), 2017
Abstract Purpose: To investigate whether modulating GSK-3β could attenuate myocardial ischemia reperfusion injury (MIRI) induced acute lung injury (ALI) and analyze the underlying mechanism. Methods: Male SD rats were subjected to MIRI with or without myocardial ischemic post-conditioning in the...

Morphological and immunohistochemical analysis of apoptosis in the cerebellum of rats subjected to focal cerebral ischemia with or without alcoholism model

Acta cir. bras; 31 (9), 2016
ABSTRACT PURPOSE: To evaluated histopathological changes, morphometric and expression of proteins CASPASE-3, BCL-2 and XIAP related to apoptosis in the cerebellum after induction of temporary focal cerebral ischemia followed by reperfusion, with or without a model of chronic alcoholism. METHODS: Fifty ...

Hepato-protective effect of rutin via IL-6/STAT3 pathway in CCl4-induced hepatotoxicity in rats

Biol. Res; 48 (), 2015
BACKGROUND: Carbon tetrachloride (CCl4) induces hepatotoxicity in animal models, including the increased blood flow and cytokine accumulation that are characteristic of tissue inflammation. The present study investigates the hepato-protective effect of rutin on CCl4-induced hepatotoxicity in rats. RESULT...
