Non-Protein-Coding RNA Instability in the Human Postmortem Brain.
Article in Toxicologic pathology, 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
A majority of the human genome codes for genes that do not produce proteins. Many of these long non-coding RNA (lncRNA) transcripts have evolved at a faster rate than genes that code for proteins, have critical regulatory and structural roles, and have important roles in higher-level brain functioning and diseases. We have shown selective time and cell-type stability of RNA transcripts in human brain during the postmortem interval. Here, we have extended these studies to examine the stability of lncRNAs in a simulated human postmortem interval. We found that lncRNA stability is variable and cell-type specific. While some lncRNAs are stable for up to 24 hours, those expressed in neurons decline rapidly and those expressed in glial cells such as astrocytes and microglia increase dramatically during this same time interval. The lncRNAs are less stable than protein-coding RNAs, and microRNAs were highly unstable in the simulated postmortem interval. Knowing the stability of human brain protein-coding and non-coding genes in the postmortem interval is critical to interpret studies of all human brain disorders ranging from Alzheimer's disease to schizophrenia.
