Dynamics of nuclear export of pre-ribosomal subunits revealed by high-speed single-molecule microscopy in live cells.
Article in iScience, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
We present a study on the nuclear export efficiency and time of pre-ribosomal subunits in live mammalian cells, using high-speed single-molecule tracking and single-molecule fluorescence resonance energy transfer techniques. Our findings reveal that pre-ribosomal particles exhibit significantly higher nuclear export efficiency compared to other large cargos like mRNAs, with around two-thirds of interactions between the pre-60S or pre-40S and the nuclear pore complexes (NPCs) resulting in successful export to the cytoplasm. We also demonstrate that nuclear transport receptor (NTR) chromosomal maintenance 1 (CRM1) plays a crucial role in nuclear export efficiency, with pre-60S and pre-40S particle export efficiency decreasing by 11-17-fold when CRM1 is inhibited. Our results suggest that multiple copies of CRM1 work cooperatively to chaperone pre-ribosomal subunits through the NPC, thus increasing export efficiency and decreasing export time. Significantly, this cooperative NTR mechanism extends beyond pre-ribosomal subunits, as evidenced by the enhanced nucleocytoplasmic transport of proteins.
