Abstract
El cáncer colorrectal (CCR) constituye uno de los tipos de tumores más frecuente y con mayores tasas de mortalidad en las sociedades occidentales. Además, diversos autores han demostrado la relación existente entre la obesidad y el riesgo a desarrollar cáncer colorrectal. En este contexto, la disfunción de los tejidos adiposos y, más concretamente, de los tejidos adiposos omental y subcutáneo, puede tener un papel importante en la fisiopatología de la obesidad y del cáncer colorrectal. Sin embargo, aunque no se conocen los mecanismos exactos que vinculan ambas patologías, se dispone de datos preliminares acerca del impacto que podría tener la expresión de los microARNs. Por otro lado, a pesar de los conocimientos sobre el papel que desempeña la función telomérica en la progresión tumoral y en el pronóstico clínico de pacientes afectados de cáncer colorrectal, su relación con la expresión de microARNs asociados a senescencia, y su papel en el mantenimiento de la función tisular de los tejidos adiposos, todavía no es conocida...
Colorectal cancer (CRC) is one of the most frequent types of tumors and one with the highest mortality rates in Western societies. In addition, several authors have shown the relationship between obesity and the risk of developing colorectal cancer. In this context, the dysfunction of the adipose tissues and, more specifically, of the omental and subcutaneous adipose tissues, may play an important role in the physiopathology of obesity and colorectal cancer. However, although the exact mechanisms that link both diseases are not known, preliminary data is available about the impact that the expression of microRNAs could have. On the other hand, despite the knowledge about the role that telomeric function plays in tumor progression and in the clinical prognosis of patients with colorectal cancer, its relationship with the expression of microRNAs associated with senescence, and its role in the maintenance of the tissue functionality of adipose tissues, is not fully understood...
