1 · What the graph read from it

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.

2 · The registry

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

TAR DNA-binding protein-43 (TDP-43) is the principal component of ubiquitinated inclusions in amyotrophic lateral sclerosis (ALS) and the most common pathological subtype of frontotemporal dementia-frontotemporal lobar degeneration with TDP-43-positive inclusions (FTLD-TDP). To date, the C-terminus of TDP-43, which is aggregation-prone and contains almost all ALS-associated mutations, has garnered much attention while the functions of the N-terminus of TDP-43 remain largely unknown. To bridge this gap in our knowledge, we utilized novel cell culture and computer-assisted models to evaluate which region(s) of TDP-43 regulate its folding, self-interaction, biological activity and aggregation. We determined that the extreme N-terminus of TDP-43, specifically the first 10 residues, regulates folding of TDP-43 monomers necessary for proper homodimerization and TDP-43-regulated splicing. Despite such beneficial functions, we discovered an interesting dichotomy: full-length TDP-43 aggregation, which is believed to be a pathogenic process, also requires the extreme N-terminus of TDP-43. As such, we provide new insight into the structural basis for TDP-43 function and aggregation, and we suggest that stabilization of TDP-43 homodimers, the physiologically active form of TDP-43, may be a promising therapeutic strategy for ALS and FTLD-TDP.
