Monitoring phosphorylation of the pyruvate dehydrogenase complex.
Article in Analytical biochemistry, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 96 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 pyruvate dehydrogenase multienzyme complex (PDC) is a key regulatory point in cellular metabolism linking glycolysis to the citric acid cycle and lipogenesis. Reversible phosphorylation of the pyruvate dehydrogenase enzyme is a critical regulatory mechanism and an important point for monitoring metabolic activity. To directly determine the regulation of the PDC by phosphorylation, we developed a complete set of phospho-antibodies against the three known phosphorylation sites on the E1 alpha subunit of pyruvate dehydrogenase (PDHE1alpha). We demonstrate phospho-site specificity of each antibody in a variety of cultured cells and tissue extracts. In addition, we show sensitivity of these antibodies to PDH activity using the pyruvate dehydrogenase kinase-specific inhibitor dichloroacetate. We go on to use these antibodies to assess PDH phosphorylation in a patient suffering from Leigh's syndrome. Finally, we observe changes in individual phosphorylation states following a small molecule screen, demonstrating that these reagents should be useful for monitoring phosphorylation of PDHE1alpha and, therefore, overall metabolism in the disease state as well as in response to a myriad of physiological and pharmacological stimuli.
