New insights into the role of sphingosine 1-phosphate and lysophosphatidic acid in the regulation of skeletal muscle cell biology
چکیده انگلیسی

Lysophospholipids are bioactive molecules that are implicated in the control of fundamental biological processes such as proliferation, differentiation, survival and motility in different cell types. Here we review the role of sphingosine 1-phosphate (S1P) and lysophosphatidic acid (LPA) in the regulation of skeletal muscle biology. Indeed, a wealth of experimental data indicate that these molecules are crucial players in the skeletal muscle regeneration process, acting by controllers of activation, proliferation and differentiation not only of muscle-resident satellite cells but also of mesenchymal progenitors that originate outside the skeletal muscle. Moreover, S1P and LPA are clearly involved in the regulation of skeletal muscle metabolism, muscle adaptation to different physiological needs and resistance to muscle fatigue. Notably, studies accomplished so far, have highlighted the complexity of S1P and LPA signaling in skeletal muscle cells that appears to be further complicated by their close dependence on functional cross-talks with growth factors, hormones and cytokines. Our increasing understanding of bioactive lipid signaling can individuate novel molecular targets aimed at enhancing skeletal muscle regeneration and reducing the fibrotic process that impairs full functional recovery of the tissue during aging, after a trauma or skeletal muscle diseases. This article is part of a Special Issue entitled Advances in Lysophospholipid Research.


► S1P and LPA regulate muscle precursor cell biology.
► S1P and LPA regulate growth, migration and proliferation of myoblasts.
► S1P and LPA cross-communicate with growth factors, hormones and cytokines.
► S1P and LPA regulate skeletal muscle metabolism, muscle adaptation and fatigue.
