Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Carboxy-terminal PDZ ligand of nNOS (CAPON) protein, as an adaptor, binds to nNOS via the PDZ domain helping regulate neuronal nitric oxide synthase (nNOS) activity at post-synaptic sites in neurons (Jaffrey et al., Neuron, 20, 115-124, 1998). Recently, it has been reported that CAPON is present in mouse muscle and may be involved in mouse muscle growth, injury, and repair possibly by regulating the stability, activity, or position of nNOS (Segalat et al., Experimental Cell Research, 302, 170-179, 2005). The present study was to explore the expression patterns and roles of CAPON as well as NOS in rat muscle regeneration after nerve injury. Normal Sprague-Dawley rats were subjected to right sciatic nerve crush injury. Walking track analysis, real time polymerase chain reaction, Western blotting, in situ hybridization, immunocytochemistry, and co-immunoprecipitation techniques were used. It revealed that CAPON mRNA increased, which peaked on days 1 and 28, whereas nNOS mRNA underwent a downregulation in the ipsilateral gastrocnemius muscles after sciatic nerve injury. Their proteins approximately paralleled the mRNA expression. CAPON and nNOS were identified in the activated satellite cells or myotubes and their in vivo interaction was verified. However, eNOS and iNOS proteins suffered an upregulation and were detected in activated satellite cells or myotubes. These data suggest that CAPON and all these three isoforms of NOS might be involved in muscle regeneration after nerve injury. Further study is necessary for a better understanding of the potential functional link between CAPON, NOS, and muscle regeneration, with possible application to therapy for skeletal muscle repair from nerve injury. © 2007 Humana Press Inc.
