CREsted provides detailed insights into enhancer codes of mouse cortical cell types, demonstrating high prediction accuracy and cross-species generalization.
Achieved on log-transformed predictions and peak heights for mouse motor cortex test set regions, demonstrating strong predictive capabilities.
| Feature | CREsted (Fine-tuned) | gReLU (22M) |
|---|---|---|
| All Test-Set Peaks (Pearson r) | 0.82*** | 0.79 |
| Cell-Type-Specific Peaks (Pearson r) | 0.79*** | 0.76 |
| TFBS Identification | Highly Accurate | Lower Accuracy |
CREsted consistently outperforms gReLU models on both all test-set peaks and cell-type-specific peaks.
Cross-Species Prediction Example
CREsted successfully scored the chicken UACA gene locus using the mouse Pvalb class model, resulting in a strong correlation (r = 0.62). This indicates the potential for identifying and decoding candidate enhancers in species without scATAC-seq data.
CREsted successfully models human PBMC data, accurately identifies validated TFBSs, and interprets complex enhanceosome structures.
Achieved on cell-type-specific test peaks for human peripheral blood mononuclear cells, confirming robust performance across tissues.
Enhancer Code Interpretation Process
IFNB1 Enhanceosome Deciphered
DeepPBMC retrieved a large part of the interferon-β (IFNB1) enhanceosome's complexity, only missing a few TFBSs (p50, c-Jun, and one IRF). Compared to Borzoi, DeepPBMC identified substantially more (34%) important nucleotides.
CREsted compares mesenchymal-like cancer cell states across tumor types and cell lines, and demonstrates efficient transfer learning from foundation models.
| Characteristic | Melanoma MES-like | GBM MES-like |
|---|---|---|
| Shared Regulators | AP-1, TEAD, RUNX, NFI, ATF/CREB | AP-1, TEAD, RUNX, NFI, ATF/CREB |
| Cell-line Specific | TEAD motifs | SOX, RFX motifs |
| Biopsy Correlation (Topic 8) | Strong | Strong |
CREsted reveals shared and specific regulatory programs across different MES-like cancer cell states.
DeepBICCN2 classified 171 in vivo-validated cell-type-specific enhancers with an average recall of 0.79 in a multi-label classification setting, highlighting biological relevance.
CREsted facilitates the design and in vivo validation of cell-type-specific and dual-specificity synthetic enhancers in a developing zebrafish atlas.
Synthetic Enhancer Design Workflow
Dual-Specificity Enhancers
CREsted enabled the generation of dual-specificity enhancers for cardiac vs. somatic muscle cells. While sequences converged to targets, precisely controlling expression magnitude remains nontrivial.
74% of 54 validated enhancers showed high and specific predictions for their corresponding cell-type class, demonstrating the model's accuracy for organism-level design.
