Identification of MTFR1 as a Novel Prognostic Biomarker and Putative Oncogene for Breast Cancer: A Multi-Omics Analysis and in Vitro Experimental Validation.
Article in IET systems biology. 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
Mitochondrial Fission Regulator 1 (MTFR1) plays a critical regulatory role in various malignancies; however, its specific function and clinical significance in breast cancer (BRCA) remain unexplored. This study systematically characterised MTFR1 by integrating multi-omics data, spatial transcriptomics, and single-cell sequencing, followed by in vitro experimental validation. MTFR1 was significantly overexpressed in BRCA tissues and predominantly localised to malignant cells. Functionally, MTFR1 was closely associated with cell cycle progression; in vitro knockdown significantly suppressed cell proliferation and induced cell cycle arrest. Clinically, high MTFR1 expression served as an independent predictor of poor prognosis and was linked to chemotherapy resistance. Cross-cancer immunotherapy analyses revealed that MTFR1 exhibited improved predictive performance for anti-PD-1 response during the on-treatment phase compared with pretreatment settings. This study elucidates the multidimensional role of MTFR1 as a putative oncogene in BRCA, highlighting it as a promising prognostic biomarker and therapeutic target.
