NEW INSIGHTS ON THE REGULATION OF CANCER CACHEXIA BY N-3 POLYUNSATURATED FATTY ACIDS.

Pharmacol Ther 2018 Dec 3. Epub 2018 Dec 3.

Institute of Physical Activity Sciences and Sports, Cruzeiro do Sul University, Sao Paulo, Brazil,; Institute of Biomedical Sciences, University of Sao Paulo, Sao Paulo, Brazil;. Electronic address:

Cancer cachexia is a multifactorial syndrome that develops during malignant tumor growth. Changes in plasma levels of several hormones and inflammatory factors result in an intense catabolic state, decreased activity of anabolic pathways, anorexia, and marked weight loss, leading to cachexia development and/or accentuation. Inflammatory mediators appear to be related to the control of a highly regulated process of muscle protein degradation that accelerates the process of cachexia. Read More
