Nitric oxide as a signaling factor to upregulate the death-specific protein in a marine diatom, Skeletonema costatum, during blockage of electron flow in photosynthesis.
Article in Applied and environmental microbiology, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 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
To determine the physiological functions of a novel death-specific protein gene, Skeletonema costatum DSP-1 (ScDSP-1) in a marine diatom, Skeletonema costatum, the mRNA abundance of ScDSP-1 was measured in cultures subjected to light manipulation and treatments with various chemicals. When cells were transferred to a dim light intensity of 15 micromol m(-2) s(-1), ScDSP-1 mRNA levels showed a transient increase of 1 to 17.2 micromol (mol 18S rRNA)(-1) in 60 h. Furthermore, treatments with the photoinhibitors 3-(3,4-dichlorophenyl)-1,1-dimethylurea (DCMU) and 2,5-dibromo-3-methyl-6-isopropyl-p-benzoquinone (DBMIB) resulted in high ScDSP-1 mRNA levels, which reached 943 and 72 micromol (mol 18S rRNA)(-1), respectively. Treatment with the nitric oxide (NO) donor diethylamine nitric oxide also induced ScDSP-1 expression, and this inducible expression was inhibited by the NO scavenger hemoglobin. Additionally, the expression of ScDSP-1 mRNA elicited by DCMU and DBMIB was efficiently reduced when cultures were pretreated with the cell-penetrating NO scavenger 2-(4-carboxyphenyl)-4,5-dihydro-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide. In contrast, treatment with another photoinhibitor, paraquat, had no effect on ScDSP-1 expression. Our results indicated that NO is the crucial secondary messenger which signals the expression of ScDSP-1 when electron flow between photosystem II and photosystem I is blocked in S. costatum cells. In addition, the discovery of a similar gene, ScDSP-2, is briefly described.
