... times higher levels of plasma creatine kinase (CK) and self-reporting of initial perceived soreness and exertion, yet muscle size and strength gains were not different for the two groups. RT-PCR analysis revealed similar increases in levels of the growth factor IGF-1Ea mRNA in both groups. Likewise...

... expression,α- actin was the first structural gene to be switched on at the 16-somite stage, followed by myosin heavy chain, troponin T, troponin I and muscle creatine kinase. The final mRNA in the series to be expressed was troponin C . All genes were switched on prior to myofibril assembly. The troponin C...

... compartments, distances, gradients and diffusion. As in all of biology,however, complexity dominates, and to such a degree that one pathway may consist of several reactions that each behave according to different rules.`Soluble' creatine kinase operates at or near equilibrium, while mitochondrial...

.... Here, we provide an overview of the role of spatially arranged enzymatic networks, catalyzed by creatine kinase,adenylate kinase, carbonic anhydrase and glycolytic enzymes, in efficient high-energy phosphoryl transfer and signal communication in the cell. Studies of transgenic creatine kinase...

... in the muscles of any other mammal and they have a rapid shortening velocity. Differences in isometric twitch contraction times between different muscles are, at least in part, probably due to differences in cytosolic creatine kinase activities. * e-mail: [email protected] 13 5 2002...

...Christopher G. Guglielmo; Theunis Piersma; Tony D. Williams SUMMARY Exercise-induced muscle damage is a well-described consequence of strenuous exercise, but its potential importance in the evolution of animal activity patterns is unknown. We used plasma creatine kinase (CK) activity...

...Munenori Noguchi; Taketoshi Sawadah; Toshikazu Akazawa ABSTRACT The energy supply for eukaryotic ciliary and flagellar movement is thought to be maintained by ATP-regenerating enzymes such as adenylate kinase, creatine kinase and arginine kinase. In this study, the energy-supplying system...

... parvalbumin concentrations, to a different volume fraction of the sarcoplasmic reticulum in the two muscles or to different Ca 2+ -ATPase activities. Alternatively, the lower content of cytosolic creatine kinase (CK) in the soleus compared with the EDL muscle could indicate that the observed difference...
