Enantiomeric specificity of (-)-2,2',3,3',6,6'-hexachlorobiphenyl toward ryanodine receptor types 1 and 2.
Article in Chemical research in toxicology, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 54 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
Polychlorinated biphenyls (PCBs) with unsymmetrical chlorine substitutions and multiple orthosubstitutions that restrict rotation around the biphenyl bond may exist in two stable enantiomeric forms.Stereospecific binding and functional modification of specific biological signaling targets have not been previously described for PCB atropisomers. We report that (-)-2,2',3,3',6,6'-hexachlorobiphenyl [(-)-PCB 136] enhances the binding of [3H]ryanodine to high-affinity sites on ryanodine receptors type 1(RyR1) and type 2 (RyR2) (EC50 values ~0.95 microM), whereas (+)-PCB 136 is inactive at < or =10 microM.(-)-PCB 136 induces a rapid release of Ca2+ from microsomal vesicles by selective sensitization of RyRs, an effect not antagonized by (+)-PCB 136. (-)-PCB 136 (500nM) enhances the activity of reconstituted RyR1 channels 3-fold by stabilizing the open and destabilizing the closed conformational states. The enantiomeric specificity is also demonstrated in intact HEK 293 cells expressing RyR1 where exposure to (-)-PCB 136 (100 nM; 12 h) sensitizes responses to caffeine, whereas (+)-PCB 136 does not. These data show enantiomeric specificity of (-)-PCB 136 toward a broadly expressed family of microsomal Ca2+ channels that may extend to other chiral noncoplanar PCBs and related structures.Evidence for enantioselective enrichment of PCBs in biological tissues that express RyR1 and RyR2channels may provide new mechanistic leads about their toxicological impacts on human health
