The skeletal muscle tissue has a remarkable ability to alter its plastic structural and functional properties after a harmful stimulus, regulating the expression of proteins in complex events such as muscle regeneration. In this context, considering that potential therapeutic agents have been widely studied, nutritional strategies have been investigated in order to improve the regenerative capacity of skeletal muscle. There is evidence of the modulatory action of fatty acids, such that oleic and linoleic acids, that are abundant in Western diets, on muscle function and trophism. Thus, fatty acids appear to be potential candidates to promote or impair the recovery of muscle mass and function during regeneration, since they modulate intracellular pathways that regulate myogenesis. This study is the first to describe and discuss the effect of fatty acids on muscle plasticity and trophism, with emphasis on skeletal muscle regeneration and in vitro differentiation of muscle cells.
骨骼肌组织在受到有害刺激后具有显著改变其可塑性结构和功能特性的能力,在诸如肌肉再生等复杂事件中调节蛋白质的表达。在此背景下,鉴于潜在治疗药物已得到广泛研究,人们对营养策略进行了研究,以提高骨骼肌的再生能力。有证据表明脂肪酸具有调节作用,例如西方饮食中丰富的油酸和亚油酸对肌肉功能和营养状况的调节作用。因此,脂肪酸似乎是促进或损害再生过程中肌肉质量和功能恢复的潜在候选物质,因为它们调节细胞内调节肌生成的信号通路。本研究首次描述并讨论了脂肪酸对肌肉可塑性和营养状况的影响,重点是骨骼肌再生和肌肉细胞的体外分化。
