Construction of a Porcine Skeletal Muscle-Specific Promoter by Inducing the Seed Region of miR-208a.

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
Transgenic promoter systems are of great interest for their potential use in gene therapy or production due to their high activity, long term, and cell specificity. Here, in order to obtain promoters with high activity and expressed specifically in skeletal muscle, the MYOD1, MYF5, and MCK were selected as the candidate genes. The truncated promoters were amplified and their activity was verified through dual-luciferase reporter gene test. We used genetic engineering techniques to improve promoter activity by tandemly linking enhancers and promoters or two promoters. Furthermore, synthetic promoter was the most active when two eMCK enhancers and pMCK promoter were cascaded. To improve the tissue specificity of the promoter, the seed region of translational repressor miR-208a was inserted into the downstream of the promoter (pGL3-2eMCK-pMCK-T208-mCherry-EGFP). The results showed that the expression level of target genes decreased significantly (P < 0.05) in myocardium rather than in skeletal muscle. The results of in vivo transfection indicated that tandem transcriptional regulatory elements can increase promoter activity in mice. This work laid the foundation for future research on genetically modified pigs.
