WebAug 6, 2016 · Here, we describe our experience using cardiotoxin as a potent myonecrotic agent to study skeletal muscle regeneration. We provide a detailed protocol to examine … WebSep 4, 2007 · To further study the role of uPA during muscle regeneration, we used the model of CTX-induced muscle injury, wherein regeneration can be analyzed in a more time-controlled fashion. Consistent with the mdx model, the loss of uPA impaired muscle regeneration in the CTX model ( Fig. 4 c and supplemental material).
WebNov 8, 2016 · Skeletal muscle tissue has an enormous regenerative capacity that is instrumental for a successful defense against muscle injury and wasting. The … WebMay 30, 2024 · CTX-injured muscle regeneration has been widely accepted as a valid means of investigating the mechanism of skeletal muscle regeneration and differentiation . Generally, the expression of myogenin and Myh are up-regulated and regenerative muscle fibers with centered nuclei are seen during muscle regeneration after CTX injury (40, 68).
WebNov 14, 2012 · To determine whether squirrels maintain the ability to actively regenerate muscle during hibernation, we injured the gastrocnemius muscle by intramuscular administration of the snake venom cardiotoxin (CTX) [20]. Injury during torpor did not interrupt the normal hibernation pattern nor trigger arousal in any of the torpid squirrels. As mentioned above, CTX-induced muscle injury is characterized by the influx of calcium, which might have contributed to the upregulation of the Akt-mTOR axis. In the present study, the expression of the upstream mTORC1 intermediates, e.g. p-Akt and p-mTOR, peaked 5 days following CTX injury compared to … See more We demonstrated that the slower type IIa fibers were more vulnerable to CTX-injection and that the formation of primarily fast muscle fibers preceded the slow fibers in the TA, i.e. slow type IIa fibers were decreased at d2 and … See more Our data reveal that CTX severely impacts muscle histology and molecular signaling. To better understand the regeneration process, the potential physiological meaning(s) of the … See more In their response upon injury, molecular targets exhibit differential expression patterns, reflecting their unique functioning during the … See more Besides the upregulation of a muscle stress response, muscle regeneration is also characterized by an anabolic response (Ge et al. 2009). mTORC1 signaling, which is the key regulator of protein synthesis, … See more
