The retroviral restriction factor TRIM5/TRIM5α regulates mitochondrial quality control.
Article in Autophagy, 2023. 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
The protein TRIM5 is under intensive investigation related to its roles in antiviral defense, yet its underlying mechanisms of action remain elusive. In our study, we performed an unbiased identification of TRIM5-interacting partners and found proteins participating in a wide variety of cellular functions. We utilized this proteomics data set to uncover a role for TRIM5 in mitophagy, a mitochondrial quality control system that is impaired in multiple human diseases. Mitochondrial damage triggers the recruitment of TRIM5 to ER-mitochondria contact sites where TRIM5 colocalizes with markers of autophagosome biogenesis. Cells lacking TRIM5 are unable to carry out PRKN-dependent and PRKN-independent mitophagy pathways. TRIM5 knockout cells show reduced mitochondrial function and uncontrolled immune activation in response to mitochondrial damage; phenotypes consistent with a requirement for TRIM5 in mitophagy. Mechanistically, we found that TRIM5 is required for the recruitment of the autophagy initiation machinery to damaged mitochondria, where TRIM5 acts as a scaffold promoting interactions between protein markers of mitochondrial damage and the autophagy initiation machinery.
