Other research done at Mayo has helped to refine diagnostic tests, improve treatment and assess the results of liver transplants for people with PSC. Mayo Clinic researchers also developed mathematical models to help physicians predict long-term survival for people with PSC. Researchers at Mayo Clinic also advanced the use of the fluorescence in situ hybridization, also called FISH, test in the diagnosis of bile duct cancer in people with PSC. Researchers at Mayo Clinic also are studying the DNA of people with PSC in hopes of identifying genes that increase the risk of the disease and predict its course. Basic research related to PSC and other liver diseases is conducted in the following Mayo Clinic laboratories: Cholangiopathies Laboratory Genomic and Exposomic Hepatobiology Laboratory Liver Pathobiology Laboratory PublicationsSee a list of publications about primary sclerosing cholangitis (PSC) by Mayo Clinic doctors on PubMed, a service of the National Library of Medicine.

The patient comes first. So the mission and research here is to advance how we can best help the patient, how to make sure the patient comes first in care. So in many ways, it's a cycle. It can start with as simple as an idea worked on in a laboratory, brought to the patient bedside, and if everything goes right — and let's say it's helpful or beneficial — then brought on as a standard approach. And I think that is one of the unique characteristics of Mayo's approach to research — that patient-centeredness — that really helps to put it in its own spotlight.
