Microtubule lattice conformation and integrity regulate α-tubulin acetylation.
Article in Communications biology, 2026. 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
Microtubule acetylation of lysine 40 of α-tubulin is a hallmark of stable microtubules. This luminal modification is catalyzed by α-tubulin acetyltransferase 1 (αTAT1) and reversed by histone deacetylase 6 (HDAC6). However, acetylation regulation within the microtubule lumen and the influence of lattice architecture on enzymatic activity remain poorly understood. Here, we reconstitute microtubule acetylation in vitro using purified αTAT1 and HDAC6 on microtubules assembled with defined lattice conformations. We show that αTAT1 outweighs HDAC6 enzymatic activity, but its acetylation efficiency decreases upon microtubule damage. Importantly, αTAT1 efficiently acetylates microtubules with expanded lattices, while compacted lattices impede its activity. Our findings reveal that both microtubule integrity and lattice conformation are critical regulators for αTAT1 enzymatic activity, suggesting that dynamic transitions between compacted/expanded and intact/damaged lattices modulate the acetylation pattern of microtubules in cells.
