Core Innovations
scXDR introduces a heterogeneous network transfer learning model that integrates multi-modal data (drugs, genes, cells) and aligns features and structures across different single-cell datasets. This is a significant advancement over methods relying solely on gene expression or transferring from bulk data.
Robust Performance
The model consistently outperforms existing methods in diverse scenarios, at both individual cell and cell group levels. Its robust performance is attributed to its ability to handle inherent differences between datasets and its comprehensive use of network information. Ablation studies confirm the critical role of transfer learning components.
Practical Impact
scXDR provides valuable insights for precision medicine, demonstrated through case studies including drug holiday treatment outcome prediction, melanoma drug screening, pan-cancer drug response analysis, and predicting optimal drug combinations for patient cells. The model's predictions are often validated by existing literature and clinical evidence.

Case Study: Predicting Drug Response in Drug Holiday Treatment
scXDR accurately predicts drug response for non-small cell lung cancer cells under Erlotinib drug holiday treatment. It successfully distinguishes sensitive and resistant cell populations, identifying key markers (MT-ND6, TUBA1B) whose expression correlates with drug response. This demonstrates the model's ability to inform treatment strategies for adaptive drug resistance.
