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...

Induction of brain injury and depression in rats by chronic unpredictable stress associated with the augmentation of nitrosative stress and apoptosis

Int. j. morphol; 38 (5), 2020
SUMMARY: Repeated stress is a risk factor for memory impairment and neurological abnormalities in both humans and animals. We sought to investigate the extent of (i) brain tissue injury; (ii) nitrosative and oxidative stress in brain tissue homogenates; (iii) apoptotic and survival biomarkers in brain ti...

miR-185-5p response to usnic acid suppresses proliferation and regulating apoptosis in breast cancer cell by targeting Bcl2

Biol. Res; 53 (), 2020
BACKGROUND: Breast cancer is the most common cancer types among women. Recent researches have focused on determining the efficiency of alternative molecules and miRNAs in breast cancer treatment. The AIMof this study was to determine the effect of usnic acid response-miR-185-5p on proliferation in the br...

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...

Evolución de un linfoma no Hodgkin "triple expresor" en un paciente trasplantado renal con quimioterapia DA-R-EPOCH. Caso clínico

Rev. méd. Chile; 147 (2), 2019
Patients transplanted from solid organs have an increased risk of cancer, especially lymphomas. Lymphomas correspond to 4 to 5% of malignant neoplasms in the general population and in solid organ transplant patients it reaches an incidence of 21%. The incidence of non-Hodgkin lymphomas is 10 times higher...

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...

Immunoexpression of vascular endothelial growth factor, beta-cell lymphoma 2 and cluster of differentiation 68 in cerebellar tissue of rats treated with Ganoderma lucidum

Int. j. morphol; 36 (4), 2018
Traumatic brain injury (TBI) can potentially lead to hemorrhages in all areas of the skull, which can damage cells and nerve connections. This study aims to investigate the protective effects of Ganoderma lucidum polysaccharides (GLPS) as a antioxidant on cerebellar cell tissues after traumatic brain inj...

The role of caspase-3, apoptosis-inducing factor, and B-cell lymphoma-2 expressions in term premature rupture of membrane

Abstract Objective To determine the role of caspase-3, apoptosis-inducing factor (AIF), and Bcell lymphoma-2 (Bcl-2) expressions in term premature rupture of membrane (PROM). Methods An analytic observational study with case-control design was conducted, involving 52 subjects (37-42 weeks of gestatio...

Apoptotic mechanisms in rabbits with blast-induced acute lung injury

Acta cir. bras; 33 (10), 2018
Abstract Purpose: To investigate the apoptotic mechanisms in rabbits with blast-induced acute lung injury (ALI). Methods: A total of 40 rabbits were randomly divided into a blank control group (A, n=10) and an experimental group (EXP, n=30). Explosion-induced chest-ALI models were prepared and sampled...
