A pleasure to attend a stimulating Research Professors networking event at the Royal Society. Excellent discussions on timely topics, followed by a great drinks reception and formal dinner. Many thanks to Sir David Baulcombe and Sir Paul Nurse for hosting and for the kind invitation.

Check out📖https://doi.org/10.1039/D6DD00399K 🚀 TRPM8 virtual screening study. Inactive-enriched structure-based ML shows top performance on novel chemical space. Without requiring 3D structures of this target, fine-tuning BIND, a structure-free protein language model, strong alternative.

Our new preprint. First prospective use of a transformer model for drug repurposing against Streptococcus pneumoniae, a major AMR threat. Great collaboration with Nick Croucher’s lab. Of 11 tested, 9 showed strong activity, some against multidrug‑resistant strains. #AI #AMR

Happy to share our latest research on predicting temozolomide response in low-grade glioma patients using large-scale machine learning. We explored 12 machine learning classification algorithms across six types of omics data. link.springer.com/article/10.1...

link.springer.comPredicting temozolomide response in low-grade glioma patients with large-scale machine learning - BMC MethodsBackground Temozolomide is the primary chemotherapeutic agent and first-line treatment for low-grade glioma. Although low-grade gliomas are generally less aggressive than high-grade gliomas, they can eventually progress into high-grade gliomas, making it crucial to maximise the efficacy of initial treatment. Methods We analysed data from 109 patients with low-grade gliomas in The Cancer Genome Atlas to evaluate the predictive performance of 12 machine learning classification algorithms for temozolomide response, using six types of omics data. Cross-validation and bootstrapping bias correction were applied to compare these models with a conventional biomarker-based model using promoter methylation status of O6-methylguanine-DNA methyltransferase. The Matthews Correlation Coefficient (MCC) was used as the primary evaluation metric. Results The microRNA-based model using the Extreme Gradient Boosting algorithm achieved the best performance (MCC = 0.447), outperforming both the automated machine learning method JADBio (MCC = 0.250) and the biomarker-based model (MCC = 0.331). Incorporating clinical variables, such as patient age and Karnofsky score, further improved predictive power, with the logistic regression model with optimal model complexity achieving the highest MCC (0.483). Feature importance analysis on the best model revealed six predictive microRNAs, including three tumour-related factors (miR-335, let-7f, and miR-7-2) and three potential biomarkers (miR-204, miR-6513, and miR-376). Discussion This study systematically demonstrates the potential of large-scale analyses combining machine learning and omics data to predict temozolomide response, offering superior predictive accuracy compared with standard biomarkers. However, validation in independent clinical datasets remains necessary before clinical translation.
