Abstract
Osteoarthritis (OA) is a chronic degenerative condition involving the joints caused by metabolic changes in chondrocytes metabolism. Treatment with magnetic fields (EMFs) produces benefits to patients affected by this pathology. The present research has the aim to investigate, by a proteomic approach, the effect of magnetic fields on cultured chondrocytes, because EMFs interferes greatly with OA chondrocytes metabolism. Human osteoarthritic chondrocytes were obtained from the femur head of osteoarthritis adult patients and were cultured under standard conditions and exposed for precise times both to extremely low-frequency (ELF; 100-Hz) electromagnetic fields and to the Therapeutic Application of Musically Modulated Electromagnetic Fields (TAMMEF), which are characterized by variable frequencies, intensities, and wave shapes. We tested the effects of the different exposure by 2-DE analysis and demonstrated that chondrocytes metabolism was highly influenced by the treatment with EMFs; in fact many proteins change their expression after the stimulation, but differently, depending on whether we use ELF or TAMMEF system.
