How genes in fat and muscle cells may cause insulin resistance
Molecular Mechanisms of Insulin Resistance Associated Loci
This project uses human genetics, single-cell profiling, and gene-editing to pinpoint genes in fat and other tissues that contribute to insulin resistance in people at risk for type 2 diabetes.

What this research studies
The team combines large human genetic datasets with tissue-specific gene expression data to find which genetic signals point to real causal genes, with a focus on fat (adipose) tissue as well as muscle, liver, and pancreas. They will use single-cell RNA and ATAC sequencing to see which cell types express those genes and then apply CRISPR perturbations to cells to observe how gene changes alter cell behavior. Viral delivery approaches and animal experiments will be used to study how those gene changes affect whole-body metabolism. Overall the work aims to map gene regulatory networks that drive insulin resistance and point to potential targets for new treatments.
Who could benefit from this research
Good fit: People with or at high risk for type 2 diabetes, or those willing to donate tissue or genetic data to research, would be most relevant to this work.
Not a fit: Patients expecting an immediate new therapy would likely not benefit in the short term because this is discovery-focused laboratory and preclinical research.
Why it matters
Potential benefit: If successful, this work could reveal new drug targets and biological pathways to prevent or treat insulin resistance and type 2 diabetes.
How similar studies have performed: Previous GWAS colocalization and functional genomics efforts have identified some causal genes for metabolic traits, but many loci remain untested and this project applies new single-cell and CRISPR approaches at larger scale.
