Diesel particulate matter-induced proteomic changes in three-dimensional spheroids derived from human primary cells of various tissue origins.
Article in Scientific reports, 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
This study investigated the effects of diesel particulate matter (DPM) on multiple human organs using 3D spheroids derived from eight human primary cell types. To assess the impact of DPM, we exposed these spheroids to varying concentrations of standardized DPM (Standard Reference Material, SRM 2975) and measured their viability, followed by proteomic analysis using tandem mass tag (TMT) labeling with liquid chromatography-tandem mass spectrometry (LC-MS/MS). A total of 9,707 proteins were identified, with 128 proteins exhibiting statistically significant changes (P-value < 0.05) in response to DPM exposure, as determined by two-way analysis of variance (ANOVA). Among these, five proteins, including apolipoprotein A-I (APOA1), significantly increased at higher DPM concentrations, while 36 proteins, primarily ribosomal proteins, showed notable decreases even at lower DPM levels. Canonical pathway analysis revealed activation of acute phase response signaling, liver X receptor/retinoid X receptor (LXR/RXR), and farnesoid X receptor (FXR)/RXR pathways across all spheroid types. APOA1 was identified as a potential biomarker for DPM exposure, with increased expression potentially linked to disruption in protein degradation pathways. This study provides valuable insights into the systemic toxicity of DPM, highlighting key proteomic changes across different tissue types and identifying potential biomarkers that could be used to assess exposure levels and health risks related to particulate matter.
