Effects of dithiothreitol on the amyloid fibrillogenesis of hen egg-white lysozyme.
Article in European biophysics journal : EBJ, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
At least 25 human proteins can fold abnormally to form pathological deposits that are associated with several degenerative diseases. Despite extensive investigation on amyloid fibrillation, the detailed molecular mechanisms remain rather elusive and there are currently no effective cures for treating these amyloid diseases. The present study examined the effects of dithiothreitol on the fibrillation of hen egg-white lysozyme (HEWL). Our results revealed that the fibrillation of hen lysozyme was significantly inhibited by reduced dithiothreitol (DTT(red)) while oxidized dithiothreitol (DTT(ox)) had no anti-aggregating activity. Effective inhibitory activity against hen lysozyme fibrillation was observed only when DTT(red) was added within 8 days of incubation. Our results showed that the initial addition of DTT(red) interacted with HEWL, leading to a loss in conformational stability. It was concluded from our findings that DTT(red)-induced attenuation of HEWL fibrillation may be associated with disulfide disruption and extensive structural unfolding of HEWL. Our data may contribute to rational design of effective therapeutic strategies for amyloid diseases.
