Machine Learning Models Predict Steroidogenesis with High Accuracy
Scientists at Collaborations Pharmaceuticals Inc. have developed advanced machine learning models that can accurately predict the impact of chemicals on steroidogenesis, a critical process in the human body that regulates hormone production. The research, published in Environmental Science & Technology in 2025, employed high-throughput screening and computational models to identify effective steroidogenesis modulation models. The models were validated using a prospective test set of 20 compounds, achieving 80% accuracy with conformal prediction adjustments.
Key Takeaways:
- The researchers developed a random forest model that predicted steroidogenesis inhibition with 80% accuracy using a prospective test set of 20 compounds.
- A transformer-based model (MolBART) was also developed to predict all end points simultaneously, achieving consistent performance.
- The models were trained on data from approximately 1,800 chemicals screened in H295R human adrenocortical carcinoma cells.
- The models enable predictions of both general steroidogenesis inhibition and potential molecular targets.
- The research provides a rapid and scalable system for assessing chemical impacts on steroidogenesis, supporting chemical risk assessment, product stewardship, and regulatory decision-making.
- The study was funded by the NIH National Institute of General Medical Sciences (NIGMS) and NIH National Institute of Environmental Health Sciences (NIEHS).
- Additional authors include Patricia A. Vignaux, Joshua S. Harris, Scott H. Snyder, Fabio Urbina, and Sean Ekins.
- The models were developed using data from ChEMBL, a publicly available database of bioactive compounds.
Statistics:
- The research employed high-throughput screening of approximately 1,800 chemicals.
