Recent studies have shown that drug sensitivity is closely associated with miRNA expression, highlighting the importance of predicting miRNA-drug interactions (MDIs) in understanding drug resistance mechanisms. Within this study, we propose an innovative method named MSFFMDI, which employs a dual-channel multi-source feature fusion framework based on heterogeneous networks to predict potential MDIs. The first channel focuses on attribute feature extraction. For miRNAs, we integrate the k-mer algorithm with word2vec to transform sequences into low-dimensional embeddings that capture semantic and structural information. For drugs, we utilize the graph isomorphism network to learn molecular structure features, and apply mol2vec to capture chemical and functional sequence features. The second channel extracts topological features by constructing a heterogeneous network based on integrated similarities and known associations between miRNAs and drugs. A graph attention network is used to update node embeddings, and a multi-scale convolutional neural network is employed to further extract topological representations. The features from both channels are fused and reduced via principal component analysis before being used for final prediction. A large number of rich experimental results show that MSFFMDI demonstrates excellent predictive performance on two datasets. Case studies further validate its robust performance.

Therefore, this article develops a drug repositioning approach via meta-path integration of multi-source biological information (MPMB-DR). This approach combines meta-path and biomolecular similarity information to construct high-quality negative links within heterogeneous networks.

To address these limitations, this study introduces GRNCFMDA, an advanced deep learning framework designed to improve MDA prediction efficiency. Initially, the model integrates functional and Gaussian interaction profile (GIP) similarities of microbes, along with semantic and GIP similarities of diseases, to construct a comprehensive heterogeneous network.

Inhibition of hERG potassium channel by certain compounds has the potential to delay cardiac repolarization, manifested as QT interval prolongation, thereby elevating the risk of severe cardiac arrhythmias like torsades de pointes (TdP). Accurate assessment of compounds' impact on hERG channels is crucial. Traditional methods are costly and inefficient for large-scale screening. Therefore, developing efficient and accurate computational methods for hERG inhibition prediction is critical. In this study, we present a deep learning framework, named hERG-MFFGNN, aimed at accurately predicting hERG channel blockers while providing model interpretability. To improve both accuracy and generalizability, we implement a multi-feature fusion strategy that systematically integrates molecular structural information. Initially, multiple molecular fingerprint features and molecular descriptors are fused to construct an initial feature representation. Then, graph neural networks are used to extract molecular topological features. These two sets of features are weighted and fused using an attention mechanism to form the final compound representation, enabling a more comprehensive expression of molecular features. The performance of hERG-MFFGNN is assessed using fivefold cross-validation on the benchmark dataset and external validation datasets. The results demonstrate that hERG-MFFGNN achieves AUROC of 0.909 and ACC of 0.854, highlighting its robust predictive capabilities for hERG activity across diverse datasets.
