  "abstract": "Objective: N 7 -methylguanosine ( m 7 G ) is one of the most prevalent and biologically important ribonucleic acid modifications. While several computational models exist for m 7 G site prediction in human and non-human species, none have been specifically designed to detect m 7 G modification sites in cancers. This study addresses this gap by developing a cancer-specific predictive framework for m 7 G site identification. Methods: We curated four m 7 G benchmark datasets from two cancer cell lines (human osteosarcoma and human hepatocellular carcinoma) from the Gene Expression Omnibus repository and included an additional benchmark dataset from m 7 G Hub v2.0. We developed a multi-head attention-based convolutional neural network (CNN) model using two feature encoding methods—trinucleotide composition and one-hot encoding. The model’s performance was compared to support vector machine, random forest, extreme gradient boosting, and a CNN across all five datasets. Robustness and generalizability were evaluated using 5-fold cross-validation and independent testing. Model interpretability was examined with two explanation tools. Results: The proposed model achieved the highest mean accuracy, Matthews correlation coefficient, and area under the receiver operating characteristic curve (AUROC) among the five evaluated models on each independent test dataset. Its mean accuracy ranged from 0.8397 to 0.8833 and its mean AUROC ranged from 0.9163 to 0.9489. Sensitivity was not consistently highest, and sensitivity and specificity were not uniformly superior across all evaluation settings. Feature attribution and visualization analyses characterized model representations. Conclusions: This study presents one of the first cancer-specific computational frameworks for m 7 G site prediction. By combining multi-head attention with CNNs and complementary feature encoding, our approach enhances predictive power and interpretability. The framework offers a valuable tool for elucidating disease mechanisms, mapping epitranscriptomic signatures, and accelerating biomarker and therapeutic discovery in cancer research.
