Telomere-to-telomere brown rat genome could sharpen disease research models
Researchers have successfully mapped the complete telomere-to-telomere genome of the brown rat. This discovery reveals new genes and unique reproductive mechanisms that could improve medical research models for human diseases.
Why it matters
Enhanced genetic mapping of model organisms is essential for developing more accurate treatments for human conditions like heart disease and stroke.

DOI: 10.1016/j.xgen.2026.101281 Researchers have created the most complete genetic profile of the brown rat to date, according to a UTHealth Houston-led team, paving the way for scientists to more accurately investigate genetic links to conditions like heart disease, kidney disease, high blood pressure and stroke.
The research, published in Cell Genomics , was led by corresponding author Peter Doris, Ph.D., director of the Center for Human Genetics at The Brown Foundation Institute of Molecular Medicine within McGovern Medical School at UTHealth Houston.
