Analyzing the promoters of two CYP9A genes in the silkworm Bombyx mori by dual-luciferase reporter assay.
Article in Molecular biology reports, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Cytochrome P450s (CYPs) are widespread proteins that interact with exogenous chemicals from the diet or the environment. CYP9A subfamily genes are important in the silkworm Bombyx mori. We previously reported transcriptional levels of two CYP9A genes in different tissues and their responses to sodium fluoride (NaF). In this study, promoter truncation analysis using a dual-luciferase reporter assay in B. mori ovary cells (BmN) showed that the regions -1,496 to -1,102 bp for CYP9A19, and -1,630 to -1,210 bp for CYP9A22 were essential for basal transcriptional activity. Sequence analysis of these regions revealed several transcriptional regulatory elements but no typical promoter elements. Promoter activities were regulated after NaF induction and with an obvious dose effect. Although the dual-luciferase assay has been widely used to determine the activity of a given promoter in cell lines, problems with it still exist. Our results indicate that both plasmid size and construct protocols affect the experimental results.
