MultiDCP is multi-tasks transfer learning based model. It is desiged to perform multiple tasks including dose-dependent chemical-induced differential gene expression predictions (chemical transcriptomics) and cell viability predictions for de novo drugs and de novo cell lines. This model includes four input components, a graph convolutional network based chemical fingerprint embedding module, a chemical substructure-gene interactions module, a knowledge-enabled autoencoder module and a dosage information embedding module (Figure 1). This superior performance is attributed to an innovative knowledge-enabled autoencoder for gene expression profiles, integration of multiple diverse labeled and unlabeled omics data, and the joint training of the multiple prediction tasks. We further apply MultiDCP to conduct drug repurposing for individual Alzheimer’s disease (AD) patients. The clinical potential of proposed drug leads on AD is supported by existing experimental and clinical evidence.
Linux
NVIDIA GPU is strongly recommended for speed. CPU is also supported but is slow.
