Cell-cycle dynamics of nascent transcription and mature RNA accumulation are concordant in normal fibroblasts.
Article in bioRxiv : the preprint server for biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Cell-cycle dynamics of gene expression are fundamental to life, yet their origin remains unclear. A prevailing model, derived from cancer cells, posits that transcription occurs in one cell cycle phase, while mature RNA accumulates in subsequent phases, suggesting temporal segregation of transcriptional regulation and RNA abundance. Whether this paradigm applies to normal human cells is unclear. Here, we co-profiled nascent transcription and mature RNAs in cycling human fibroblasts. The two dynamics were strongly concordant, with no evidence of a lag extending cell-cycle phases. Our data suggest a widespread transcription-to-maturation lag is not a general feature of human cells.
