RNAlater-compatible protocol for nuclei isolation from radical prostatectomy prostate cancer resections, enabling single-nucleus resolution RNA-seq.
Article in Scientific reports, 2026. 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
We present an optimised protocol for single-nucleus isolation from RNAlater-preserved prostate cancer (PC) resections that enables transcriptomically robust snRNA-seq. Our streamlined procedure employs bead-mill homogenization and high-salt lysis to generate nuclei suspensions, eliminating the need for FACS or density-gradient purification. The protocol yielded high-quality libraries (Q30 ≥ 90%) with minimal ambient RNA. Analysis of 3,365 nuclei identified eight distinct cellular compartments, preserving the full cellular repertoire, including luminal, stromal, and immune lineages. These findings demonstrate that snRNA-seq is feasible in RNAlater-preserved PC specimens enabling routine analysis of clinical samples and expanding the applicability of single-cell genomics in translational research.
