Emerging role of protein arginine methyltransferase 5 in gastrointestinal cancer (Review).
Review in Oncology letters, 2026. 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
Gastrointestinal (GI) cancer remains a leading cause of cancer-related mortality worldwide, with epigenetic alterations progressively recognized as key drivers of tumorigenesis and therapeutic resistance. Through its role in facilitating cell proliferation, inhibiting apoptosis, driving epithelial-mesenchymal transition (EMT) and metastasis, reinforcing angiogenesis, inducing metabolic reprogramming, mediating chemoradiotherapy resistance and maintaining cancer stem cell (CSC) properties, protein arginine methyltransferase 5 (PRMT5) has emerged as a key oncogenic regulator among these epigenetic modifiers implicated in GI cancer progression. Elevated PRMT5 expression has been observed in multiple GI cancer subtypes, comprising gastric cancer (GC), colorectal cancer (CRC), hepatocellular carcinoma (HCC) and pancreatic cancer, where PRMT5 markedly contributes to tumorigenesis via symmetric dimethylation of histone (e.g., dimethylation of histone H4 at arginine 3) and non-histone substrates [e.g., AKT1 and sterol regulatory element-binding protein 1a (SREBP1a)]. In GC, PRMT5 activates the PI3K/AKT pathway [e.g., by methylating AKT1 at arginine (R)391 and upregulating c-Myc], facilitating tumor cell proliferation and survival. In CRC, PRMT5-mediated methylation of SMAD4 (e.g., at R361) reinforces TGF-β signaling, facilitating EMT and metastasis, while its interaction with EGFR further amplifies proliferative signals. PRMT5 also upregulates VEGF expression (e.g., via chromatin remodeling at its promoter), stimulating angiogenesis and inhibits ferroptosis (e.g., by suppressing the solute carrier family 7 member 11/glutathione peroxidase 4 axis in HCC), supporting tumor survival. Furthermore, PRMT5 markedly contributes to metabolic reprogramming (e.g., accelerating
