Hexavalent chromium-induced alteration of proteomic landscape in human skin fibroblast cells.
Article in Journal of proteome research, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers, 1 of them a synthesis that pooled it.
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
Hexavalent chromium [Cr(VI)] generated during industrial processes is carcinogenic. Although much is known about the deleterious effects caused by reactive oxygen species generated during the reduction of Cr(VI) after its absorption by biological systems, the precise mechanisms underlying Cr(VI) cytotoxicity remain poorly defined. Here, we analyzed, at the global proteome scale, the perturbation of protein expression in GM00637 human skin fibroblast cells upon exposure to potassium dichromate (K₂Cr₂O₇). We were able to quantify ∼4600 unique proteins, among which ∼400 exhibited significant alterations in expression levels upon a 24-h treatment with 0.5 μM K₂Cr₂O₇. Pathway analysis revealed the Cr(VI)-induced perturbation of cholesterol biosynthesis, G-protein signaling, inflammatory response, and selenoprotein pathways. In particular, we discovered that the K₂Cr₂O₇ treatment led to pronouncedly elevated expression of a large number of enzymes involved in de novo cholesterol biosynthesis. Real-time PCR analysis revealed the increased mRNA expression of selected genes involved in cholesterol biosynthesis. Consistently, K₂Cr₂O₇ treatment resulted in marked increases in cellular cholesterol level in multiple cell lines. Moreover, the Cr(VI)-induced growth inhibition of cultured human cells could be rescued by a cholesterol-lowering drug, lovastatin. Together, we demonstrated, for the first time, that Cr(VI) may exert its cytotoxic effect, at least partly, through the up-regulation of enzymes involved in de novo cholesterol biosynthesis and the resultant increase of cholesterol level in cells.
