Studies demonstrate that long non-coding RNAs (lncRNAs) and their protein interactions (LPIs) play crucial roles in regulating gene expression and participating in diverse biological processes. Aberrant expression of these interactions is closely associated with the initiation and progression of various diseases. Therefore, investigating LPI prediction is critical for elucidating disease mechanisms and identifying potential biomarkers and therapeutic targets. Given the high costs and limited efficiency of traditional biological methods, developing cost-effective and accurate computational models for LPI prediction becomes essential. Inspired by similarity network fusion and hypergraph learning, this study proposes a computational framework named MFH-LPI. First, we construct separate similarity networks for lncRNAs and proteins, then employ an attention mechanism to extract and fuse key features from these multi-view networks. Subsequently, we introduce a hypernode (randomly generated node) to establish a heterogeneous hypergraph integrating lncRNAs and proteins, thereby capturing richer node representations. Finally, we predict LPIs using a multilayer graph convolutional network (GCN) combined with a fully connected (FC) layer. We conduct several experiments on three datasets to validate the method's effectiveness. The experimental findings indicate that the suggested model is effective compared to existing processes and outperforms other approaches.
研究表明,长链非编码RNA(lncRNAs)及其与蛋白质的相互作用(LPIs)在调节基因表达和参与多种生物学过程中发挥着关键作用。这些相互作用的异常表达与各种疾病的发生和发展密切相关。因此,研究LPI预测对于阐明疾病机制以及识别潜在的生物标志物和治疗靶点至关重要。鉴于传统生物学方法成本高昂且效率有限,开发用于LPI预测的经济高效且准确的计算模型变得至关重要。受相似性网络融合和超图学习的启发,本研究提出了一个名为MFH-LPI的计算框架。首先,我们为lncRNAs和蛋白质构建单独的相似性网络,然后采用注意力机制从这些多视图网络中提取并融合关键特征。随后,我们引入一个超节点(随机生成的节点)来建立一个整合lncRNAs和蛋白质的异质超图,从而捕获更丰富的节点表示。最后,我们使用多层图卷积网络(GCN)结合全连接(FC)层来预测LPIs。我们在三个数据集上进行了多项实验以验证该方法的有效性。实验结果表明,与现有方法相比,所提出的模型是有效的,并且优于其他方法。
