ABSTRACT
Hepatocellular carcinoma (HCC) is one of the most common malignant tumours and its five-year survival rate remains low. Autophagy is a catabolic process conserved among all eukaryotes ranging from yeast to mammals. Recently, many studies show that tumour cells can utilize autophagy as a cellular defence mechanism when facing metabolic stress. Thus, we hypothesize that autophagy may play an important role in the resistance of hepatocellular carcinomas to therapy. Although the exact role of autophagy on tumour cells is still complex and further studies are needed to prove the impact of autophagy on HCC, it suggests that autophagy may be a new therapeutic target for the resistance to therapy of HCC.
RESUMEN
El carcinoma hepatocelular (CHC) es uno de los tumores malignos más comunes, y su tasa de super-vivencia a los cinco años sigue siendo baja. La autofagia es un proceso catabólico conservado en todos los eucariotas, que abarca desde las levaduras hasta los mamíferos. Recientemente, numerosos estudios han demostrado que las células tumorales pueden utilizar la autofagia como un mecanismo celular de defensa frente al estrés metabólico. De este modo, sostenemos la hipótesis de que la autofagia puede desempeñar un papel importante en la resistencia de los carcinomas hepatocelulares a la terapia. Aunque el papel exacto de la autofagia en las celulares tumorales sigue siendo complejo, y se requieren más estudios a fin de probar el impacto de la autofagia en el CHC, hay indicios de que la autofagia puede ser un nuevo objetivo terapéutico para la resistencia a la terapia del CHC.
