GLO1 and how it affects obesity, type 2 diabetes, and fatty liver disease
Official title: Glyoxalase 1 and its Role in Metabolic Syndrome
Funded at University of Arizona · NIH-11290384 · Data updated 2026-11-12
This project tests whether changing the enzyme GLO1 can protect adults who have or are at risk for obesity, type 2 diabetes, and fatty liver disease.

Who could benefit from this research
✓Could help
People most relevant would be adults with overweight/obesity, prediabetes or type 2 diabetes, or diagnosed non-alcoholic fatty liver disease.
✕Less likely to help
People without metabolic disease or whose conditions are driven by unrelated causes may not benefit from approaches targeting GLO1.
What this research studies
The researchers use genetic tools and diet models in animals to study how the enzyme GLO1 influences weight gain, blood sugar control, and liver fat. They created mice lacking GLO1 and compare them to normal mice on high-fat, high-sugar diets to see differences in weight, glucose tolerance, and liver steatosis. The team measures levels of the metabolic byproduct methylglyoxal (MGO), looks at gene activity linked to metabolism, and uses those findings to guide ideas for future human treatments. Results from these lab and animal experiments would inform whether targeting GLO1 could be a route to new therapies for metabolic disease.
Why it matters
Potential benefit: If successful, this work could point to new ways to prevent or treat obesity, type 2 diabetes, and non-alcoholic fatty liver disease by targeting GLO1 or its metabolic pathway.
How similar studies have gone: Early animal experiments from this team show protective effects when GLO1 is reduced, but translation to human treatments remains untested.
