Mapping gene-drug interactions using large language models (GPT-4o and Gemini)
Mapping gene-drug interactions using large language models (GPT-4o and Gemini)
GeneRxGPT is an automated large language model (LLM) pipeline that integrates real-time PubMed literature to infer drug–gene relationships in cancer with improved accuracy and reduced hallucination. By systematically combining literature retrieval with advanced LLM reasoning, GeneRxGPT enables rapid, evidence-grounded discovery of therapeutic targets and drug repurposing opportunities across diverse cancer types.

Highlight at AACR 2024: GPT-4 and gene-drug interactions
Highlight at AACR 2024: GPT-4 and gene-drug interactions
Michael's presentation at the American Association for Cancer Research (AACR) Annual Meeting 2024 has been selected as a highlight by the NCI Division of Cancer Biology (DCB; @NCICancerBio). In this study, we prototyped an efficient and accurate GPT-4 tool for analyzing gene-drug interactions through scientific literature in collaboration. Watch the DCB's interview with Michael and read the abstract.
shinyDeepDR is a user-friendly tool designed for predicting anti-cancer drug sensitivity using deep learning. With the tool, users can effortlessly perform an in silico screening of 265 approved and investigational compounds by uploading mutation and/or gene expression data from a cancer sample.

DepLink is a web server to identify genetic and pharmacologic perturbations that induce similar effects on cell viability or molecular changes. It integrates heterogeneous datasets of genome-wide CRISPR screens, high-throughput drug screens, and gene expression signatures of perturbations. Read the article.
