Dual-Channel Heterogeneous Graph Neural Network for Predicting microRNA-Mediated Drug Sensitivity

Abstract: Many studies have confirmed that microRNAs (miRNAs) are mediated in the sensitivity of tumor cells to anticancer drugs. MiRNAs are emerging as a type of promising therapeutic targets to overcome drug resistance. However, there is limited attention paid to the computational prediction of the associations between miRNAs and drug sensitivity. In this work, we proposed a heterogeneous network-based representation learning method to predict miRNA-drug sensitivity associations (DGNNMDA). An miRNA-drug heterogeneous … Show more

“…In terms of model architecture, the multi‐channel model may contribute to obtaining high‐quality embedding representations of multiple types of nodes in heterogeneous graphs. Existing works have attempted to address the heterogeneous graph issue by using multi‐channel models, such as DGNNMDA, which leverages dual channels to represent ncRNAs and drugs, respectively (Deng, Fan, et al, 2022). In addition, the attention mechanism can increase the interpretability of the model, it is thus often used in AI models of ncRNA‐drug association prediction.…”

“…Therefore, it is necessary to randomly sample the negative samples equal to the number of positive samples before training models. The sampling strategy that ranks samples according to the similarity matrix and selects the least similar ones as negative samples is more reliable than the random sampling strategy (Deng, Fan, et al, 2022).…”
