DGAT1 as a Racially Divergent Driver of Carcinoma-Associated Fibroblast Activation Drives Tumorigenic Pathways via ERK1/2 Signaling in Prostate Cancer.
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
Background: The incidence of lethal prostate cancer (PCa) is disproportionately higher in African American (AA) men compared to Caucasian (Cau) men. Racial differences in lipid reprogramming have been implicated in PCa progression. Recent studies identified race-specific biological alterations in carcinoma-associated fibroblasts (CAF). Here, we demonstrate that lipid-laden CAF from AA patients (AA Methods: DGAT1-regulated genes in fibroblasts were identified by transcriptomic profiling, and their biological consequences were evaluated in vivo. Patient-derived CAF from AA and Cau men were examined to determine their molecular response to DGAT1 inhibition during tumorigenesis. Results: Lipid droplet (LD) biogenesis analysis revealed DGAT1-dependent LD accumulation in AA Conclusions: Our findings reveal elevated DGAT1 expression in AA
