Characterization of the expression profiles of calpastatin (CAST) gene in chicken.
Article in Molecular biology reports, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The calpain system, a Ca(2+)-activated protease family, plays an important role in postmortem tenderization of skeletal muscle due to its involvement in the degradation of important myofibrillar and associated proteins, as well as in cytoskeletal remodeling and regulation of muscle growth. In this study, we quantified the expression of calpastatin (CAST) in two Chinese chicken breeds (mountainous black-bone chicken breed (MB) and a commercial meat type chicken breed (S01)), to discern the tissue and age-related specific expression pattern and its potential role on muscle tissue metabolism. Real-time quantitative PCR (RT-qPCR) assay was developed for accurate measurement of CAST mRNA levels in various tissues from chicken with different ages (0, 2, 4, 6, 8, 10, and 12 week). CAST mRNA was detected in collected organs. The heart and leg muscle tissues had the highest expression of CAST than other tissues from the same chicken (P < 0.01). Age-related expression pattern of CAST gene was evident in breast muscle, liver, and brain tissues (P < 0.05), but not in heart and leg muscle tissues (P > 0.05). Overall, the CAST mRNA level exhibited a "rise-decline-rise-decline" developmental change in breast muscle and liver, with the highest expression at 2 weeks and the lowest expression at 8 weeks. The S01 chicken had significantly higher expression of CAST in breast muscle and heart than the MB chicken (P < 0.05) at 10 weeks. Our results suggested the CAST expression may be related to muscle fiber development.
