Metabolic environment-driven remodeling of mitochondrial ribosomes regulates translation and biogenesis.
Article in Molecular cell, 2025. 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
Cytosolic translation activity is fine-tuned by environmental conditions primarily through signaling pathways that target translation initiation factors. Although mitochondria possess their own translation machinery, they lack an autonomous signaling network analogous to their cytosolic counterpart for regulating translation activity. Consequently, our understanding of how mitochondrial translation activity is adjusted under different metabolic environments remains very limited. Here, we report a noncanonical mechanism for regulating mitochondrial translation activity via metabolism-dependent changes in the mitochondrial ribosome (mitoribosome) in S. cerevisiae. These changes arise from a metabolism-modulated mitoribosome assembly pathway that regulates the composition and conformation of the mitoribosome, thereby adjusting its translation activity to meet metabolic demands. Moreover, the translation activity of the mitoribosome feeds back to regulate the biogenesis of nuclear-encoded mitochondrial proteins, influencing mitochondrial functions and aging. Such a ribosomal remodeling-based "gear-switching" mechanism represents an orthogonal mode of translation regulation, compensating for the absence of a translation-modulating signaling network within mitochondria.
