Two Tetrahymena kinesin-9 family members exhibit slow plus-end-directed motility in vitro.
Article in Scientific reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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 kinesin-9 family comprises two subfamilies specific to ciliated eukaryotic cells, and has recently attracted considerable attention because of its importance in ciliary bending and formation. However, only scattered data are available on the motor properties of kinesin-9 family members; these properties have not been compared under identical experimental conditions using kinesin-9 motors from the same species. Here, we report the comprehensive motor properties of two kinesin-9 molecules of Tetrahymena thermophila, TtK9A (Kif9/Klp1 ortholog) and TtK9B1 (Kif6 ortholog), using microtubule-based in vitro assays, including single-motor and multi-motor assays and microtubule-stimulated ATPase assays. Both subfamilies exhibit microtubule plus-end-directed, extremely slow motor activity, both in single and multiple molecules. TtK9A shows lower processivity than TtK9B1. Our findings indicate that the considerable slow movement of kinesin-9 that corresponds to low ATP hydrolysis rates is a common feature of the ciliary kinesin-9 family.
