WebJan 1, 2024 · Differentiating myocytes express myomaker and myomerger (also called myomixer or minion) that work independently to regulate the different steps of cell fusion into multinucleated myofiber [4–7]. Myomaker regulates the membrane hemifusion, while myomerger is necessary for fusion pore formation [8]. WebNecroptosis has been demonstrated to be dependent on receptor interacting protein 1 (RIP1) and specifically on its kinase activity. RIP1 phosphorylation of RIP3 results in the activation of mixed lineage kinase domain like protein (MLKL), and this study, together with {1,2}, showed that this induces necroptotic death by rupturing of the plasma membrane. harvel\\u0027s ring location

WebJan 25, 2024 · Myofiber necrosis is a significant pathologic characteristic of idiopathic inflammatory myopathies (IIMs), and its molecular mechanism is largely unknown. Necroptosis is a recently identified form of regulated necrotic cell death, and its activation might have crucial biologic consequences. WebOur work indicates that apoptosis and necroptosis are associated with a loss of membrane integrity in Lipin1 Myf5cKO muscle and that myofiber death and dysfunction may cause a decrease in contractile force.
