Implicación de la quinasa humana VRK1 y el factor de transcripción SOX2 en la regulación del ciclo celular a través de la inducción de ciclina D1

Abstract

Una correcta regulación del ciclo celular es necesaria para que el proceso de proliferación ocurra de forma adecuada. En este trabajo, demostramos que la quinasa VRK1 y el factor de transcripción SOX2 regulan la progresión del ciclo celular induciendo la expresión de ciclina D1(CCND1), proteína implicada en la transición G1/S. Por el contrario, las macrohistonas mH2A1.2 y mH2A2 actúan como represores transcripcionales, inhibiendo la expresión de VRK1 al impedir el acceso del factor de transcripción SOX2 a las regiones promotoras de sus genes diana. Alteraciones de los niveles de SOX2, VRK1 y macrohistonas provocan la desregulación de los procesos de proliferación y diferenciación pudiendo causar tumorigénesis. Teniendo en cuenta estos resultados, se propone la necesidad de profundizar en el estudio de estas macrohistonas junto a VRK1 y SOX2 considerándolas como posibles candidatas para el desarrollo de nuevas terapias contra el cáncer.
