Astemizole, an inhibitor of ether-à-go-go-1 potassium channel, increases the activity of the tyrosine kinase inhibitor gefitinib in breast cancer cells

Rev. invest. clín; 71 (3), 2019
Abstract Background Expression and activity of the potassium channel ether-à-go-go-1 (EAG1) are strongly related to carcinogenesis and tumor progression, which can be exploited for therapeutic purposes. EAG1 activity may be reduced by preventing its phosphorylation with epidermal growth factor receptor...

The effect of hirudin on antagonisting thrombin induced apoptosis of human microvascular endothelial cells

Acta cir. bras; 34 (1), 2019
Abstract Purpose: To investigate whether hirudin exerts its antithrombin action to decrease the ratio of Human Microvascular Endothelial Cells (HMVECs) apoptosis. Methods: Human microvascular endothelial cells (HMVECs) cultured in the third and fifth generations were used. HMVECs were divided into nor...

Involvement of endothelial CK2 in the radiation induced perivascular resistant niche (PVRN) and the induction of radioresistance for non-small cell lung cancer (NSCLC) cells

Biol. Res; 52 (), 2019
BACKGROUND: Tumor microenvironment (TME) plays a vital role in determining the outcomes of radiotherapy. As an important component of TME, vascular endothelial cells are involved in the perivascular resistance niche (PVRN), which is formed by inflammation or cytokine production induced by ionizing radiat...

The Application Methods of Mitogen-activated Protein Kinase Signal Pathway Inhibitors SP600125 and SB203580 in Long-term in Vivo Experiments

West Indian med. j; 67 (2), 2018
ABSTRACT Objective: To explore the application methods of mitogen-activated protein kinase signal pathway inhibitors SP600125 and SB203580 in long-term in vivo experiments. Methods: A total of 55 healthy New Zealand rabbits were randomly divided into blank control group, model control group, SP low dos...

La inhibición de Rho quinasa post infarto mejora el remodelado y la función ventricular: mecanismos involucrados a nivel preclínico

Rev. chil. cardiol; 36 (3), 2017
Resumen: Objetivo: Determinar algunos mecanismos moleculares por los cuales la activación de ROCK cardíaca post infarto del miocardio (IAM) participa en el remodelado y en deterioro de la función sistólica. Métodos: Determinación simultánea de niveles de proteínas blanco de ROCK cardíaca, de f...
