The localisation and stability of the CENP-F protein are regulated by importin beta and microtubules in mitotic cells.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
CENP-F is a large protein acting in fundamental cell cycle processes, including nuclear envelope breakdown, mitotic microtubule function and chromosome segregation. These activities are mediated by specific CENP-F protein elements that interact with microtubules, motor proteins, centrosomes and kinetochores. CENP-F is then ubiquitinated and degraded in late mitosis. The C-terminal region of CENP-F contains regulatory elements, including a region required for nuclear localisation in interphase and a KEN box driving proteolysis in late mitosis. Here we show that CENP-F generates proximity ligation products with importin beta during mitosis. Furthermore, induction of importin beta overexpression influences CENP-F at two levels: it alters CENP-F mitotic localisation, promoting its accumulation at spindle poles and decreasing its association with kinetochores, and also causes its persistence in the late mitotic window in which CENP-F normally disappears, in a process that requires microtubule integrity and dynamics. These data implicate therefore importin beta in spatial and temporal control of CENP-F during mitosis, and uncover a functional interplay between CENP-F's ability to regulate mitotic microtubules and, in turn, a protective role of microtubules against CENP-F premature ubiquitination.
