Viral and pharmacogenomic testing help clinicians detect infection early, tailor immunosuppression, and improve long-term outcomes for organ transplant recipients.
In Mayo Clinic’s Advanced Diagnostics Laboratory, there are dozens of projects underway at once to develop new technologies, discover novel findings, validate new tests, and support physicians in providing advanced patient care. For example, researchers are using phage immunoprecipitation sequencing (PhIP-Seq) to discover new serological biomarkers for autoimmune diseases. In a recent study using PhIP-Seq, Mayo Clinic researchers discovered a previously unknown antibody marker for immune-mediated rippling muscle disease (iRMD). This finding will support testing options and accurate diagnosis of iRMD, helping physicians treat patients with iRMD and restore their quality of life.
Kenneth Hobby assumed his fever, fatigue, and aching pains in May 2018 were from another bout of malaria. He was on one of his frequent visits to Zambia in southern Africa, where the mosquito-borne parasite is common. But anti-malaria drugs didn't help, and soon Kenneth had such disabling pain that he could barely walk.
In a recent study, Mayo Clinic researchers developed the first cellular DNA barcoding with a machine-learning approach to reveal previously unknown metastatic behavior of tumor cells. Researchers barcoded the DNA of millions of human ovarian cancer cells and transplanted them in mice, where rare tumor initiating cells and their progenies could be tracked within the primary tumor as well as in every other organ they were spreading into. The entire community of cells generated by a single barcoded cell had identical barcodes. This enabled the tracking of a large number of benign and metastatic clones by sequencing DNA barcodes in tumors and various organs, including blood and ascites. Using the cellular DNA barcoding approach and a newly developed data analysis system, researchers could track clonal growth dynamics in various metastatic sites and trace it back to its ancestral tumor-initiating cell. They used artificial intelligence to tackle the complex data to identify if the clonal metastatic spread is happening peritoneally or through blood routes.
