Abstract

Abstract Recent advancements in single-cell technologies have enabled comprehensive characterization of cellular states through transcriptomic, epigenomic, and proteomic profiling at single-cell resolution. These technologies have significantly deepened our understanding of cell functions and disease mechanisms from various omics perspectives. As these technologies evolve rapidly and data resources expand, there is a growing need for computational methods that can integrate information from different modalities to facilitate joint analysis of single-cell multi-omics data. However, integrating single-cell omics datasets presents unique challenges due to varied feature correlations and technology-specific limitations. To address these challenges, we introduce scMODAL, a deep learning framework tailored for single-cell multi-omics data alignment using feature links. scMODAL integrates datasets with limited known positively correlated features, leveraging neural networks and generative adversarial networks to align cell embeddings and preserve feature topology. Our experiments demonstrate scMODAL’s effectiveness in removing unwanted variation, preserving biological information, and accurately identifying cell subpopulations across diverse datasets. scMODAL not only advances integration tasks but also supports downstream analyses such as feature imputation and feature relationship inference, offering a robust solution for advancing single-cell multi-omics research.

  • AI-driven models applied to triple-negative breast cancer merge bulk and single-cell transcriptomics data to discover drug-responsive subpopulations.

    “AI-driven models are also applied to discover drug-responsive subpopulations in triple-negative breast cancer, merging bulk and single-cell transcriptomics data (Wang Y. et al., 2025).”

    From Spatial pharmacology of anti-cancer immunomodulators: a comprehensive review (2026) · cites this paper as Wang Y. et al., 2025

    The Results sections on multimodal integration describe benchmarking scMODAL with blood and bone-marrow datasets, not an analysis of triple-negative breast cancer. Searches for drug-responsive subpopulations and the combination of bulk and single-cell transcriptomics found no passage addressing the claim. The available passages do not establish a contrary finding either. (LLM, conf=0.75)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
