For instance, m6A modifications in gastric cancer (GC) have been significantly implicated in tumor progression, metastasis, and treatment resistance. GC is characterized by the differential expression of m6A regulators. High expression writers such as METTL3 and WTAP are associated with poor prognosis and aggressive clinical features. Conversely, low expression of METTL14 is linked to worse clinical outcomes, whereas elevated levels of demethylases, such as FTO and ALKBH5, correlate with better survival rates. These m6A regulators influence several cellular biological functions, including proliferation, invasion, migration, glycolysis, and chemotherapy resistance, thereby affecting tumor growth and therapeutic outcomes. The assessment of m6A modification patterns and the expression profiles of m6A-related genes hold substantial potential for improving the clinical diagnosis and treatment of GC. In this review, we provide an updated and comprehensive summary ofthe role of m6A modifications in GC, emphasizing their molecular mechanisms, clinical significance, and translational applications in developing novel diagnostic and therapeutic strategies.  \nKeywords m6A, Expression, Molecular mechanism, Biological functions, Treatment resistance  \n*Correspondence: Penghui Li[lph0819@163.com](lph0819@163.com)  \nFull list of author information is available at the end of the article  \n© The Author(s) 2025.

European Journal of Medical Research (2025) 30:98 Page 2 of 17  \nGraphical Abstract  \nIntroduction  \nGastric cancer (GC), a malignant tumor, continues to bea significant global health concern [1, 2]. Although certain countries have witnessed a decline in incidence and mortality rates, it remains the third leading cause of cancer-related deaths worldwide [3, 4]. The outcome for GC is generally unfavorable, particularly when diagnosed atan advanced stage [5]. Traditional treatment methods, including surgery, chemotherapy, and radiotherapy, display limited effectiveness, especially in advanced cases. Recent progress has been witnessed in developing new therapies such as immune checkpoint inhibitors, cellbased immunotherapy, and cancer vaccines [6–9]. However, the majority of patients are diagnosed at later stages due to the lack of widespread early screening programs, which significantly affects treatment success and","cbCaieVqykZTezva","https://ap.wps.com/l/cbCaieVqykZTezva","pdf",1809996,17,"English","# Introduction\n## m6A modifications and enzymes in cancer\n## Relevance to gastric cancer and clinical need","[{\"question\":\"Why are m6A modifications important in gastric cancer?\",\"answer\":\"m6A modifications are implicated in tumor progression, including metastasis and treatment resistance.
