Abstract

Airway smooth muscle contraction is critical for maintenance of appropriate airway tone, and has been implicated in asthma pathogenesis. Smooth muscle contraction requires an "engine" (myosin activation) and a "transmission system" (actin cytoskeletal remodeling). However, the mechanisms that control actin remodeling in smooth muscle are not fully elucidated. The adapter protein Crk-associated substrate (CAS) regulates actin dynamics and the contraction in smooth muscle. In addition, profilin-1 (Pfn-1) and Abelson tyrosine kinase (c-Abl) are also involved in smooth muscle contraction. The interplays among CAS, Pfn-1 and c-Abl in smooth muscle have not been previously investigated. The association of CAS with Pfn-1 in mouse tracheal rings was evaluated by co-immunoprecipitation. Tracheal rings from c-Abl conditional knockout mice were used to assess the roles of c-Abl in the protein-protein interaction and smooth muscle contraction. Decoy peptides were utilized to evaluate the importance of CAS/Pfn-1 coupling in smooth muscle contraction. Stimulation with acetylcholine (ACh) increased the interaction of CAS with Pfn-1 in smooth muscle, which was regulated by CAS tyrosine phosphorylation and c-Abl. The CAS/Pfn-1 coupling was also modified by the phosphorylation of cortactin (a protein implicated in Pfn-1 activation). In addition, ACh activation promoted the spatial redistribution of CAS and Pfn-1 in smooth muscle cells, which was reduced by c-Abl knockdown. Inhibition of CAS/Pfn-1 interaction by a decoy peptide attenuated the ACh-induced actin polymerization and contraction without affecting myosin light chain phosphorylation. Furthermore, treatment with the Src inhibitor PP2 and the actin polymerization inhibitor latrunculin A attenuated the ACh-induced c-Abl tyrosine phosphorylation (an indication of c-Abl activation). Our results suggest a novel activation loop in airway smooth muscle: c-Abl promotes the CAS/Pfn-1 coupling and actin polymerization, which conversely facilitates c-Abl activation. The positive feedback may render c-Abl in active state after contractile stimulation.

Attention Score in Context

This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 02 February 2018.
All research outputs
#6,472,070
of 12,452,101 outputs
Outputs from Respiratory Research
#640
of 1,452 outputs
Outputs of similar age
#143,426
of 372,129 outputs
Outputs of similar age from Respiratory Research
#29
of 49 outputs
Altmetric has tracked 12,452,101 research outputs across all sources so far. This one is in the 47th percentile – i.e., 47% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,452 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.0. This one has gotten more attention than average, scoring higher than 53% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 372,129 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 60% of its contemporaries.
We're also able to compare this research output to 49 others from the same source and published within six weeks on either side of this one. This one is in the 38th percentile – i.e., 38% of its contemporaries scored the same or lower than it.
