1 · What the graph read from it

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.

2 · The registry

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

backgroundThe isolation of intact cell populations from archived tissue is critical for understanding cell-type-specific functions in neuroscience. This study presents a streamlined, bench-ready fluorescence-activated cell sorting (FACS) protocol for the isolation of neuronal and non-neuronal populations from frozen adult rat cortex, specifically optimized for integrated RNA and protein analyses.

methodsThe method employs a gentle enzymatic digestion and mechanical trituration, followed by fixation with zinc salts, which successfully addresses the challenges of dissociating adult brain tissue while preserving key cellular markers. The protocol’s versatility is demonstrated by its compatibility with two distinct collection buffers, enabling the simultaneous preparation of samples for both RNA and protein analysis, performed by qRT-PCR and mass spectrometry, respectively.

resultsNeuronal (PE+) and non-neuronal (PE-) fractions were isolated with high purity, as confirmed by significant enrichment of Rbfox3, Map2, and Tubb3 (neuronal) and Gfap, Iba1, Olig2, and Cldn5 (non-neuronal) via qRT-PCR. Subsequent proteomic analysis further confirmed the distinct identities of the sorted populations, with key neuronal and non-neuronal markers showing significant enrichment in their respective fractions.

conclusionsDespite a conservative yield (ca. 20,000 neurons per sample) prioritized for cellular intactness, the obtained material was sufficient for high-sensitivity qPCR (mRNA/miRNA) and mass spectrometry. This accessible and time-efficient protocol provides a robust platform for parallel RNA and protein analysis of defined brain cell populations from archived frozen tissue.
