RNACOREX: Open‑Source Platform Reveals Interpretable Cancer Gene‑Regulation Networks and Predicts Patient Survival

Breaking: Open-Source RNACOREX Maps Cancer Survival Networks With Interpretable Insights

In Navarra, Spain, researchers unveiled RNACOREX, an open-source software platform aimed at identifying gene regulation networks tied to cancer survival. The tool was created by the Institute of Data Science and Artificial Intelligence and the Cancer Center at Clínica Universidad de Navarra, with testing across thirteen tumor types sourced from a global cancer data consortium.

RNACOREX is designed to analyze thousands of biological molecules together, revealing crucial molecular interactions often missed by conventional methods. By producing a clear, interpretable molecular map, the software helps scientists understand how tumors operate and provides a framework to study the biological processes driving cancer progression.

How RNACOREX Works

within human cells, microRNAs and messenger RNA communicate through intricate regulatory networks. When these networks malfunction, cancers can emerge or advance. The platform aims to capture the architecture of these networks, a task that has been challenging due to vast data volumes, noise, and the need for accessible, precise tools that distinguish meaningful interactions from false signals.

RNACOREX addresses these challenges by merging curated facts from international databases with real-world gene-expression data. It ranks the most biologically meaningful miRNA-mRNA interactions and progressively builds more complex networks that can also function as probabilistic models to study disease behavior.

Performance and Practical Meaning

To gauge effectiveness,the team applied RNACOREX to data from thirteen cancer types,including breast,colon,lung,stomach,melanoma,and head-and-neck tumors. The results showed survival predictions with accuracy on par with advanced AI models, but with the added benefit of obvious explanations of the underlying molecular interactions.

Beyond predicting survival, RNACOREX can reveal regulatory networks linked to clinical outcomes, identify cross-cancer patterns, and highlight individual molecules with strong biomedical relevance. These capabilities may help researchers generate new hypotheses about tumor growth and progression and point toward potential diagnostic markers or treatment targets. The researchers describe the tool as a reliable molecular map that prioritizes new biological targets, potentially speeding up cancer research.

Open-Source and Future Progress

RNACOREX is freely available as an open-source project on GitHub and PyPI, with built-in tools for downloading databases to streamline integration into laboratory workflows. The project has received partial funding from regional and European programs, reflecting a commitment to making genomics research more accessible and reproducible.

As artificial intelligence increasingly intersects with genomics, the authors position RNACOREX as an explainable, easy-to-interpret choice to black-box models. The team also plans to expand the platform with pathway analysis and additional molecular interaction layers, aiming to create models that more comprehensively explain tumor growth and progression.

RNACOREX: Open‑Source Platform for Interpretable Cancer Gene‑Regulation Networks

What Is RNACOREX?

• Open‑source software designed to map post‑transcriptional coregulatory interactions across cancer genomes.
• Built on RNA‑seq and miRNA‑seq data from The Cancer Genome Atlas (TCGA) and other high‑throughput repositories.
• Generates visual, interpretable networks that link transcription factors, miRNAs, and target genes, revealing hidden layers of gene regulation in tumor cells.

Core Functionalities

Feature	Description
Network Construction	Integrates expression profiles, binding site predictions, and experimentally validated interactions to create a post‑transcriptional coregulatory network for each cancer type.
Survival Modeling	Implements machine‑learning classifiers (LASSO, Random Forest, Gradient Boosting) that use network features to predict overall and disease‑free survival.
Classification Metrics	Outputs AUROC, accuracy, precision, and recall for each tumor dataset, enabling direct comparison of model performance.
User‑Amiable Interface	Command‑line tools and a web‑based dashboard for interactive network exploration and result export.
Extensibility	Supports custom datasets, choice feature sets, and plug‑in modules for additional analytical methods.

How RNACOREX Builds interpretable Gene‑Regulation Networks

1. Data Ingestion – Loads raw counts from RNA‑seq,miRNA‑seq,and clinical files.
2. Normalization & Filtering – Applies TMM or DESeq2 normalization; removes low‑expressed genes (<1 CPM in ≥80 % of samples).
3. Correlation Matrix – Computes Pearson/Spearman correlations between miRNA-mRNA pairs, adjusting for batch effects using ComBat.
4. Binding site Integration – Overlays miRNA target predictions (TargetScan, miRDB) and RNA‑binding protein (RBP) motifs from CLIP‑seq databases.
5. Network Pruning – Retains only statistically meaningful edges (FDR < 0.05) that satisfy both expression correlation and binding evidence.
6. module Detection – applies Louvain clustering to identify tightly coupled gene/miRNA modules, each annotated with pathway enrichment (KEGG, Reactome).
7. Interpretability Layer – Assigns edge importance scores derived from contribution to survival models,allowing researchers to pinpoint regulatory hubs that drive prognosis.

Survival Prediction Workflow

• Feature Engineering – Extracts module eigengenes, hub‑gene expression, and edge importance scores as predictors.
• Model training – Splits data into 70 % training / 30 % test; uses 5‑fold cross‑validation to tune hyper‑parameters.
• Risk Stratification – Generates a risk score for each patient; dichotomizes into high‑ vs. low‑risk groups using the Youden index.
• Validation – Performs Kaplan-Meier analysis and log‑rank tests; reports C‑index and time‑dependent AUC.
