Maintenance of chaperone-mediated autophagy activity in cultured cells expressing mutant huntingtin.
Article in Biomedical reports, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Huntington's disease (HD) is an autosomal dominant neurodegenerative disease caused by mutant huntingtin (Htt) with an expanded polyglutamine tract. It has been reported that Htt regulates autophagy. However, it remains unclear whether mutant Htt affects chaperone-mediated autophagy (CMA). Our study aimed to investigate the effect of mutant Htt on CMA activity in cultured HEK293T cells. A HEK293T cell model of HD was produced by transient transfection of wild-type (20Q) or mutant (120Q) Htt plasmids. The effect of mutant Htt on two CMA components, lysosomal-associated membrane protein 2a (Lamp2a) and heat-shock cognate protein 70 (Hsc70), was determined by western blotting and immunofluorescent staining. We observed that mutant Htt did not significantly alter the expression of Lamp2a and Hsc70 when compared to normal Htt. These findings suggest that mutant Htt does not reduce CMA activity and that enhancing CMA activity to clear mutant Htt may be a novel strategy for the management of HD.
