Resumen
La glicoproteína eritropoyetina ha sido por mucho tiempo conocida por su función eritropoyética en la regulación de la producción de glóbulos rojos, lo que derivó en el tratamiento exitoso de la anemia asociada a diferentes enfermedades. Sin embargo, tanto la expresión de la hormona como la de su receptor específico fueron observadas en tejidos no hematopoyéticos lo que generó, en años recientes, el desarrollo de numerosos experimentos in vitro e in vivo que demuestran la protección de distintos tejidos no hematopoyéticos por eritropoyetina. En este trabajo se presenta una revisión del aporte de nuestro laboratorio al conocimiento de mecanismos involucrados en la citoprotección por eritropoyetina, tales como inhibición de apoptosis y de estrés oxidativo, inducción de angiogénesis, así como comportamientos variables en un ambiente inflamatorio. La importancia de estos conocimientos radica no solo en la posibilidad de establecer nuevas estrategias terapéuticas enfocadas a la protección de distintos tejidos sino también a evitar efectos no deseados del tratamiento.
The glycoprotein erythropoietin has long been known for its erythropoietic function in the regulation of red blood cell production, which led to the successful treatment of anemia related to different diseases. However, both the expression of the hormone and that of its specific receptor were also observed in non-hematopoietic tissues, thus leading, in recent years, to the development of numerous in vitro and in vivo experiments demonstrating protection of such tissues by erythropoietin. This review presents our laboratory’s contribution to the knowledge of the mechanisms involved in the cytoprotective effects of erythropoietin, such as the inhibition of apoptosis and oxidative stress and the induction of angiogenesis, as well as a variable behaviour in an inflammatory environment. The importance of these findings lies not only in the possibility of establishing new therapeutic strategies focused on the protection of different tissues, but also in avoiding the undesired effects of the treatment.
