Hotspot Cancer Mutation Impairs KAT8-mediated Nucleosomal Histone Acetylation.
Article in Journal of molecular biology, 2024. 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
KAT8 is an evolutionarily conserved lysine acetyltransferase that catalyzes histone acetylation at H4K16 or H4K5 and H4K8 through distinct protein complexes. It plays a pivotal role in male X chromosome dosage compensation in Drosophila and is implicated in the regulation of diverse cellular processes in mammals. Mutations and dysregulation of KAT8 have been reported in human neurodevelopmental disorders and various cancers. However, the precise mechanisms by which these mutations disrupt KAT8's normal function, leading to disease pathogenesis, remain largely unknown. In this study, we focus on a hotspot missense cancer mutation, the R98W point mutation within the Tudor-knot domain. Our study reveals that the R98W mutation leads to a reduction in global H4K16ac levels in cells and downregulates the expression of target genes. Mechanistically, we demonstrate that R98 is essential for KAT8-mediated acetylation of nucleosomal histones by modulating substrate accessibility.
