Cancer cachexia is a systemic multifactorial syndrome that alters several metabolic pathways and is mainly characterized by intense protein depletion from skeletal muscle. Depending on the progression of the disease, up to 80% of patients are affected by this syndrome, which is responsible for around 30% of all cancer-related deaths. More studies are needed to identify new strategies for a coadjuvant therapeutic treatments that can help to improve the quality of life of patients, for this reason, the objective of this project is to evaluate whether the amino acid leucine associated with the aqueous extract of acerola (Malpighia emarginata DC.) can be able to minimize the activity of the neoplastic cell without causing damage to the muscle cell. For this purpose, an aqueous extract from acerola will be prepared and standardized in terms of phenolic constituents, under the hypothesis that the supplement (extract/leucine) can present modulatory activity in vitro assay using neoplastic cells and skeletal muscle cells, and the effects of the supplement without causing damage to the muscle cell.
