microARNs como biomarcadores de enfermedad cardiovascular

0

miRNAAl menos cuatro microARNs que pueden detectarse en el plasma sanguíneo permiten diferenciar la disección espontánea de la arteria coronaria del infarto aterotrombótico del miocardio, y arrojan luz sobre la patogenia de la enfermedad. Los detalles en Lozano-Prieto M, Adlam D, García-Guimaraes M, Sanz-García A, Vera-Tomé P, Rivero F, et al. Differential miRNAs in acute spontaneous coronary artery dissection: Pathophysiological insights from a potential biomarker. EBioMedicine. 2021;66:103338.

Avanza la biopsia líquida en el estudio del ADN

0

AvancesEl estudio del ADN circulante, por medio de una muestra de sangre, abre nuevas perspectivas en el diagnóstico oncológico, aunque se exploran sus aplicaciones en el infarto del miocardio, el ictus y otras afecciones. Un editorial habla sobre su introducción en el laboratorio clínico: Jiménez W. Biopsia líquida: un reto para el laboratorio de diagnóstico clínico. Avances en Medicina de Laboratorio, 2020; DOI: https://doi.org/10.1515/almed-2020-0036.
