James Luyendyk<\/a>, Albert C. and Lois E. Dehn Endowed Chair in Veterinary Medicine and associate dean for research in Michigan State University\u2019s College of Veterinary Medicine. \u201cNot only was the hypothesis wrong, the result was essentially the opposite of what we anticipated.\u201d <\/p>\nWhat began as a basic research question in a veterinary medicine laboratory ultimately helped shape a clinical study involving human patients \u2014 an example of One Health research in action. <\/p>\n
Luyendyk studies how blood clotting and liver biology intersect. His laboratory set out to investigate plasminogen, a protein involved in breaking down blood clots that previous research suggested played an important role in liver regeneration. <\/p>\n
When the data says you\u2019re wrong <\/p>\n
The team expected their experiments to confirm what previous studies had reported, paving the way for the next phase of research. <\/p>\n
Instead, they found the opposite. <\/p>\n
When researchers reduced plasminogen levels in mice, the liver produced more new cells and showed signs of stronger regeneration after surgery. <\/p>\n
\u201cScience moves forward when you\u2019re willing to follow the data, even when it tells you you\u2019re wrong,\u201d Luyendyk said. \u201cIn this case, the data challenged what we thought we knew about liver regeneration and opened an entirely new path for investigation.\u201d <\/p>\n
The unexpected findings did more than challenge scientific thinking. They caught the attention of Patrick Starlinger, a liver surgeon and researcher at Mayo Clinic who was involved in a multicenter clinical trial evaluating tranexamic acid, or TXA, a medication commonly used to reduce bleeding during surgery. <\/p>\n
A clue for liver surgeons <\/p>\n
Inspired in part by the MSU findings, researchers examined whether the drug\u2019s effects on the plasminogen pathway might also influence liver recovery after surgery. <\/p>\n
The results were striking. <\/p>\n
Patients who received TXA had roughly three times lower odds of developing post-hepatectomy liver failure than those who received a placebo. <\/p>\n
\u201cWhen we saw the findings from the MSU team, we realized there might be an important connection between this pathway and liver regeneration,\u201d said Starlinger. \u201cTheir experimental work provided the hypothesis that led us to examine patient outcomes in the HeLiX trial. Without those findings, we likely would not have pursued this question. The possibility that a widely available, low-cost medication could substantially reduce this risk is exciting because it has the potential to improve outcomes for patients undergoing surgery for liver cancer and other serious liver diseases.\u201d <\/p>\n
The findings suggest that a pathway long thought to support liver regeneration may instead provide a target for improving recovery after surgery. While additional studies are needed, the work points to a promising new direction for reducing one of the most serious complications associated with liver surgery. <\/p>\n
One Health in action <\/p>\n
The connection between discoveries in mice and findings in human patients illustrates the principles of One Health, an approach that recognizes the links among human, animal and environmental health. <\/p>\n
\u201cThis is exactly the kind of cross-species learning that One Health is all about,\u201d Luyendyk said. \u201cWe learn something in one setting, test it in another and use those insights to improve health across species.\u201d <\/p>\n
The work may eventually have implications beyond human medicine. Liver surgery is also performed in veterinary patients, including dogs with liver tumors, raising the possibility that future discoveries could help improve outcomes for animal patients as well. <\/p>\n
Researchers caution that additional studies are needed before the findings change standard clinical practice. <\/p>\n
\u201cEvery answer produces more important questions, and this study was no different,\u201d said Luyendyk. <\/p>\n
However, because TXA is already widely used and relatively inexpensive, the discovery could accelerate future efforts to reduce complications after liver surgery. <\/p>\n
For Luyendyk, the study represents something larger than a single finding. It demonstrates how basic research can lead to unexpected discoveries \u2014 and how those discoveries can ultimately improve lives. <\/p>\n
\u201cWe followed the data, even when it contradicted what everyone expected,\u201d he said. \u201cNow we\u2019re seeing the possibility that those discoveries could improve outcomes for patients.
