Tissue-specific restriction of skeletal muscle troponin C gene expression.
Article in Gene expression, 1993. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Expression of the skeletal muscle troponin C (TnC) gene is confined to fast-twitch skeletal muscle fibers (Gahlmann et al., 1988) and appears to be subject to an unexpected form of regulation. Unlike enhancers of other muscle genes, the TnC enhancer and basal promoter are muscle cell-specific only when linked to each other. We identified a strong classical enhancer element within the 5'-flanking sequence of this gene at -1.5 kb and a basal promoter near the transcription start site. Both elements are required for the transcriptional activity of TnC test constructs in myogenic cells. When the TnC enhancer was linked to the SV40 early basal promoter, or the TnC basal promoter was linked to the SV40 enhancer, each supported expression in non-muscle cells. Nuclear factors from both muscle and non-muscle cells bind to one CTF/NF1 binding site and to two functionally related MEF2-like A/T-rich binding sites in the enhancer element. It is currently unknown whether modifications of these nuclear factors, differences in their concentrations, or their interaction with additional factors restrict human fast-twitch TnC expression to skeletal muscle cells. However, it appears that the human fast-twitch skeletal troponin C gene is restricted in non-muscle cells in a distinctive way requiring communication between its enhancer and basal promoter.
