Tau and MAP6 establish labile and stable domains on microtubules.
Article in iScience, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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 previously documented that individual microtubules in the axons of cultured juvenile rodent neurons consist of a labile domain and a stable domain and that experimental depletion of tau results in selective shortening and partial stabilization of the labile domain. After first confirming these findings in adult axons, we sought to understand the mechanism that accounts for the formation and maintenance of these microtubule domains. We found that fluorescent tau and MAP6 ectopically expressed in RFL-6 fibroblasts predominantly segregate on different microtubules or different domains on the same microtubule, with the tau-rich ones becoming more labile than in control cells and the MAP6-rich ones being more stable than in control cells. These and other experimental findings, which we studied further using computational modeling with tunable parameters, indicate that these two MAPs do not merely bind to pre-existing stable and labile domains but actually create stable and labile domains on microtubules.
