Loss of function of VCP/TER94 causes neurodegeneration.
Article in Disease models & mechanisms, 2024. 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
Variants in several genes are linked to human frontotemporal lobar degeneration (FTLD) associated with TDP43- and/or ubiquitin-positive inclusions. However, it is not yet clear whether the underlying mechanism is a gain-of-function or a loss-of-function one. To answer this question, we used Drosophila expressing double-stranded RNA against the FTLD-associated gene TER94 (an ortholog of VCP/p97) and found that the knockdown (KD) of this gene caused premature lethality, reduction in brain volume and alterations in the morphology of mushroom bodies. The changes caused by TER94 KD were rescued by wild-type TER94 but not by the human disease-linked A229E mutant, indicating that this mutant causes loss of function. Alterations were also observed in pupal brains and were partially rescued by co-expression of Mcm2, which is involved in control of the cell cycle, suggesting that dysregulation of neuronal proliferation caused the phenotypes. TER94 KD also caused the disappearance of TBPH (an ortholog of TDP43/TARDBP) from nuclei. These data from Drosophila genetics suggest that VCP-linked FTLD is caused by loss-of-function of VCP.
