An RNAi-based platform for spatiotemporal control of histone gene expression during animal development.
Article in Epigenetics & chromatin, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundMutational analysis of histones provides an important means of studying the function of histone post-translational modifications (PTMs) in epigenetic gene regulation. However, several technical challenges have impeded direct tests of histone residue function in metazoans, including the massive abundance of histone gene products, multiple copies of histone genes in the genome, and the necessity of histones for cell viability.
resultsHere, we describe a new experimental approach in Drosophila for selective depletion of the replication-dependent histone H3.2. Using short hairpin RNA (shRNA) transgenes, we demonstrate effective depletion of endogenous H3.2 gene expression, which causes defects in cell proliferation and organ development. We further show that a histone replacement transgene engineered to be insensitive to RNA interference (RNAi) fully rescues shRNA-mediated developmental defects. Last, we demonstrate that this selective depletion platform recapitulates phenotypes caused by histone gene mutation.
conclusionsWe conclude that shRNA-mediated depletion of endogenous histone H3.2, coupled with histone replacement transgenes engineered to be insensitive to RNAi, is an effective experimental approach for studying the role of histone PTMs in animal development.
