Entrevista a Guadalupe Sabio y Antonia Tomás, ganadoras del Premio de Investigación Fundación Dr. Antoni Esteve 2021

“Lo que nosotros descubrimos es que p38gamma se activa cuando la célula tiene un estrés. Ese estrés, en algunos casos, es un desencadenante de cáncer hepático ya que va a producir un aumento de la proliferación celular, es decir, que las células se empiecen a multiplicar. Es esa p38gamma que se activa la que controla la proliferación celular, ese aumento del número de células que al final va a desencadenar un tumor”.

Circadian clock and liver cancer

María Crespo, Magdalena Leiva & Guadalupe Sabio.

Circadian clocks control several homeostatic processes in mammals through internal molecular mechanisms. Chronic perturbation of circadian rhythms is associated with metabolic diseases and increased cancer risk, including liver cancer.

The mammalian circadian clock

The hepatic physiology follows a daily rhythm, driven by clock genes that control the expression of several proteins involved in distinct metabolic pathways. Alteration of the liver clock results in metabolic disorders, such as non-alcoholic fatty liver diseases (NAFLD) and impaired glucose metabolism, that can trigger the activation of oncogenic pathways, inducing spontaneous hepatocarcinoma (HCC).

In this review, we provide an overview of the role of the liver clock in the metabolic and oncogenic changes that lead to HCC and discuss new potentially useful targets for prevention and management of HCC.
