Melatonina y cáncer de mama

Abstract

Melatonin, the main hormone released by the pineal gland, has as its main function the synchronization of circadian rhythms with the environmental phenomena, mainly with the light. In the last decades, several research groups have shown the oncostatic properties of melatonin, specifically those related to breast cancer. The aim of this work is to analyze the different mechanisms by which the melatonin exerts its antitumoral action, such as: (1) antiestrogenic actions, both on circulating levels of estrogens and on estrogenic signaling pathways, (2) cell cycle regulation, proliferation, differentiation and apoptosis, (3) the regulation of invasiveness and tumor metastasis, (4) its antioxidant actions, (5) its immunostimulatory effects, (6) its antiangiogenic actions, (7) the modulating effects of circadian rhythms, (8) epigenetic regulation and (9) its telomerase activity regulation. Finally, we will analyze the role of melatonin decreasing the treatment resistance currently employed in breast cancer. Even with all the research and results obtained that support the possible beneficial properties of melatonin, its clinical use is extremely limited and more trials should be carried out to better define its usefulness in clinical oncology. We will then focus on the influence of melatonin on the development of breast cancer in order to, eventually, address the role of melatonin in different clinical trials, valuing the beneficial effects of its use along with other antitumor treatments.

La melatonina, principal hormona secretada por la glándula pineal, tiene como principal función la sincronización de los ritmos circadianos con los fenómenos ambientales, fundamentalmente con la luz. En las últimas décadas, numerosos equipos de investigación han demostrado las propiedades oncostáticas de la melatonina, especialmente sobre el cáncer de mama. En el presente trabajo analizaremos los diferentes mecanismos a través de los cuales la melatonina ejerce sus acciones antitumorales, entre los que destacan: (1) las acciones antiestrogénicas de la melatonina, tanto sobre los niveles circulantes de estrógenos como sobre las vías de señalización estrogénica, (2) la regulación del ciclo celular, a nivel de proliferación, diferenciación y apoptosis, (3) la regulación de la invasividad y metástasis tumoral, (4) sus acciones antioxidantes, (5) sus efectos inmunoestimulantes, (6) sus acciones antiangiogénicas, (7) los efectos moduladores de los ritmos circadianos, (8) la regulación epigenética y (9) su regulación de la actividad de la telomerasa. A continuación, nos centraremos en la influencia de la melatonina en el desarrollo del cáncer de mama para, finalmente, abordar el papel de la melatonina en distintos ensayos clínicos, valorando los efectos beneficiosos de su utilización junto con otros tratamientos antitumorales.
