     - Extra cellular Matrix:
            - composed of many different molecular components, consisting mostly of collagens, proteoglycans, and glycosaminoglycans
     - Matrix metalloproteinases:
            - enzymes that digest collagen which are synthesized and excreted by fibroblasts
            - required for homeostasis
            - disruption of MMP regulation due to injury / disease can alter normal ECM architecture and prevent proper force transmission;
            - zinc-dependent endopeptidases that digest collagen and other structural molecules
            - 4 types:
                   - collagenases, gelatinases, membrane-bound MMPs, and stromelysins

- DHEA effect on muscle:
DHEA Alleviates Oxidative Stress of Muscle Cells via Activation of Nrf2 Pathway.
Effect of dehydroepiandrosterone administration on recovery from mix-type exercise training-induced muscle damage.
Specific binding and effects of DHEA-S on skeletal muscle cells: implication for DHEA-S replacement therapy in myotonic dystrophy.
