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
backgroundMacrophage migration inhibitory factor (MIF) promotes inflammation, regulates immune responses and chemotherapy resistance in the tumor microenvironment. However, its mechanism of action in colorectal cancer (CRC) metabolic reprogramming and targeted therapeutic potential remain unclear. This study aims to investigate the function, mechanism, and targeted therapeutic potential of MIF in CRC.
methodsData were integrated from TCGA, GTEx, CPTAC, and HPA databases with clinical sample validation. Single-cell sequencing analysis (datasets GSE166555 and GSE144735) was performed, alongside functional assays and mechanistic studies. A novel high-potency MIF inhibitor was identified through virtual screening and validated in vitro and in vivo.
resultsMIF expression was found to be significantly elevated in CRC tissues and cell lines, correlating with poor overall survival (OS) and disease-specific survival (DSS). Single-cell sequencing confirmed malignant epithelial cells as the primary MIF source. Functional assays demonstrated that MIF knockout suppressed CRC cell proliferation, migration, and tumor growth in vivo, while MIF overexpression promoted these effects. Mechanistically, MIF binds CD74 to upregulate glycolytic enzymes (HK2, PKM2, LDHA), enhancing glucose uptake and lactate/pyruvate production, thereby driving the Warburg effect and CRC progression. Virtual screening identified a novel high-potency MIF inhibitor, F3277-0933 (IC50 = 8.284 μM). In vitro and in vivo, F3277-0933 surpassed the classical inhibitor ISO-1 in suppressing MIF-driven glycolytic reprogramming and proliferation.
conclusionThis study elucidates a novel mechanism by which the MIF-CD74 axis drives CRC progression through glycolytic reprogramming and provides robust preclinical evidence for developing MIF-targeted therapies.
