Molecular assembly of thyroglobulin induced by in vitro nitric oxide treatments: implication its role in thyroid cells.
Article in The protein journal, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 formation of amyloid-like fibrils, which polymerize from various soluble proteins under physiological and acidic conditions, causes a wide range of protein-folding diseases, such as Alzheimer's disease and Parkinson's disease. Fibril assembly in in vitro solutions containing nitric oxide, a free radical that functions as an important signalling molecule involved in numerous physiological and pathological processes, has not been reported. Here, we investigated the protein assembly that occur in thyroglobulin under mildly acidic conditions in the presence of nitric oxide. Solution studies, size exclusion chromatography, dynamic light scattering and analytical ultracentrifugation, demonstrated the size changes of thyroglobulin oligomers after nitric oxide treatment. Following electron microscopic analysis visualized their structural changes and revealed that the molecules can morphologically form polymerized fibril assemblies with a length of 2-5 μm and width 10-100 nm. Taken together, these results provide suggestive evidence for the propensity of forming polymerized thyroglobulin fibrils implying their presence in thyroid cells, which may be related to the onset or progression of thyroid diseases.
