Sensitivity of the kinase activity of human vaccinia-related kinase proteins to toxic metals.
Article in Journal of biological inorganic chemistry : JBIC : a publication of the Society of Biological Inorganic Chemistry, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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 human vaccinia-related kinase (VRK) proteins VRK1 and VRK2 regulate different processes, such as the cell cycle, DNA damage response, and signaling by mitogen-activated protein kinases in response to growth factors or cellular stress. Alterations in expression levels of these Ser-Thr kinases are associated with cancer and neurodegenerative diseases. These functions suggest that they might also be targets of toxic metals, and thus contribute to the pathogenic effects associated with metal intoxication. VRK1 is inhibited by cadmium, copper, and mercury, and VRK2 is more sensitive to cadmium and much less sensitive to copper and mercury. Both kinases are insensitive to lead and cobalt. VRK1 is in general more sensitive than VRK2 in the low micromolar range. This inhibitory effect induced by these metals was detected in an autophosphorylation assay, as well as in phosphorylation assays using p53 and histone H3 as substrates. The accumulation of these three metals in cells can contribute, by inhibition of VRKs, to their toxic pathogenic effects, particularly their neurological manifestations. In this context copper has not generally been associated with any intoxication syndrome, except Wilson's syndrome, but it might be implicated in some alterations with which it has not yet been associated.
