Damaged telomeres and telomerase in liver scarring and liver cancer
Telomere Dysfunction and Telomerase Reactivation in the Etiology and Progression of Liver Cancer
Using human stem-cell models, researchers look at how short telomeres and telomerase changes can lead to liver scarring and liver cancer for people with telomere-related risks.

What this research studies
From a patient perspective, the team uses human pluripotent stem cells engineered to carry telomerase or telomere defects to grow different types of liver cells in the lab. They compare cells with normal telomeres to cells with short or mutated telomeres to see how DNA damage builds up and which cell types fail. The project also examines common TERT promoter mutations that reactivate telomerase to understand how that change may drive cell transformation toward cancer. The goal is to map the signaling steps from telomere damage to fibrosis and hepatocellular carcinoma so researchers can target those steps in future tests and therapies.
Who could benefit from this research
Good fit: People with inherited telomerase or telomere mutations, unexplained early liver fibrosis, or a high risk of hepatocellular carcinoma would be most relevant to this line of research.
Not a fit: Patients whose liver disease is caused by factors unrelated to telomere biology, or those needing immediate clinical treatment rather than basic research, may not benefit directly from this project.
Why it matters
Potential benefit: If successful, this work could reveal why telomere damage leads to liver fibrosis and cancer and point to targets for earlier detection or new treatments.
How similar studies have performed: Animal models and genetic studies have previously linked telomere shortening and TERT promoter mutations to liver disease, but applying human pluripotent stem-cell models to study the process in human liver cell types is a newer and less-tested approach.
