A fourth-year medical student at the University of Â鶹´«Ã½<\/span> at M\u0101noa\u2019s John A. Burns School of Medicine<\/abbr><\/a> (JABSOM<\/abbr>) has helped uncover a surprising clue in one of the deadliest cancers. Thomas Mandel Clausen\u2019s research points to a little-known sugar molecule that could one day help doctors detect pancreatic cancer earlier—and potentially slow its spread.<\/p>\n

The study, published in the Journal of Clinical Investigation<\/a><\/em> (Impact Factor 13.6), began a year–and–a–half before Clausen entered JABSOM<\/abbr>.<\/p>\n

“I started working on this research right after COVID<\/abbr>, while at UCSD<\/abbr>,” Clausen said. “We had just published a big study on COVID<\/abbr> and thought some of the reagents and techniques we developed could be applied to pancreatic cancer. That\u2019s when we discovered something interesting.”<\/p>\n

Clausen\u2019s research centers on a sugar molecule called HSAT<\/abbr>. It works like heparin—a compound known for thinning blood—by interacting with proteins in the body. His team discovered that both normal pancreatic cells and the earliest cancer cells make HSAT<\/abbr>.<\/p>\n

“Basically, pancreatic cancer cells are making a heparin–like sugar—something we thought was very rare in humans. That\u2019s the big discovery,” Clausen explained.<\/p>\n

They also found that early pancreatic tumors release more HSAT<\/abbr> into tissues and blood, meaning it could help detect cancer sooner. But when the team used CRISPR<\/abbr> gene editing to stop cells from making HSAT<\/abbr>, the cancer became more aggressive.<\/p>\n

Clausen said this shows HSAT<\/abbr> may not only signal when cancer is present but could also help slow its growth.<\/p>\n

Balancing science and medicine<\/h2>\n

While these findings could have broad implications for pancreatic cancer treatment, Clausen\u2019s path to this discovery has been equally remarkable. Originally from Denmark, he trained as a biochemist, earning a PhD<\/abbr> in clinical cancer research and completing two postdocs before pursuing medicine.<\/p>\n

“It feels amazing. I\u2019ve been working on this manuscript for the three years I\u2019ve been a medical student. It\u2019s a huge relief to see it published,” he said.<\/p>\n

“Back in Denmark, we call people like me ‘eternal students,’ the ones who never finish,” he joked. “As a scientist, we do a lot of cool studies and publish a lot, but it\u2019s hard to see your research directly impact patients. That\u2019s what I yearn for.”<\/p>\n

Clausen hopes to become an oncologist who combines patient care with research, conducting studies that directly affect patients and their disease.<\/p>\n
