Integration of scRNA-seq and ST-seq identifies hyperproliferative RRM2+ cells features and therapeutic targets in gastric cancer.
Article in Journal of translational medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundDespite substantial progress in discovering novel therapeutic targets and compounds, cancer hyperproliferative cells (CHCs) play a central role in driving tumor progression in gastric cancer (GC). High-resolution single-cell RNA sequencing (scRNA-seq) integrated with spatial transcriptomics sequencing (ST-seq) elucidating the role of the CHC microenvironment in driving GC progression remains lacking.
methodsThrough integrated analysis of 40 scRNA-seq samples and 6 ST samples from human gastric tissues spanning tumor progression, we delineate the phenotypic plasticity of tumor epithelium and characterize the transcriptional trajectory from normal gastric cells to CHCs, a process associated with RRM2 overexpression. Finally, we validated the analysis results through cellular and animal experiments.
resultsOur findings demonstrate that RRM2 knockdown triggers ferroptosis in GC cells by promoting lipid peroxidation and intracellular iron accumulation. We further screen a compound and RRM2 inhibitor, osalmid, which effectively suppresses tumor growth in GC cell xenografts by triggering ferroptosis, thus offering a new therapeutic option for GC.
conclusionsThis study elucidates the critical role of RRM2 + CHCs in gastric cancer development and progression, providing novel insights for targeted therapies. The discovery of osalmid as a potential therapeutic agent offers a promising new treatment strategy for GC.
