Heart Disease & Protein Link
- Researchers at the University of Missouri have achieved a breakthrough in understanding "bad" cholesterol.
- ApoB100 acts as a molecular scaffold, enveloping LDL particles and enabling their movement.
- Zachary Berndsen, an assistant professor in the MU School of Medicine, and Keith Cassidy, an assistant professor of biological physics, used cryo-electron microscopy to determine ApoB100S structure.
Researchers at the University of Missouri have made a groundbreaking revelation: they’ve mapped the structure of ApoB100, a critical protein for LDL cholesterol transport, which could revolutionize heart disease treatment. This advancement, published in Nature, offers a new understanding of how “bad” cholesterol functions within the body. By visualizing ApoB100, scientists aim to develop highly targeted drugs, possibly reducing side effects ofen associated with current drugs. The team, leveraging advanced cryo-electron microscopy and AI, is paving the way for more accurate heart disease risk assessments by directly measuring ApoB100 levels. This is vital news for anyone concerned about their cardiovascular health, as high LDL cholesterol is a significant risk factor. News Directory 3 is tracking this story closely. Discover what’s next in this pivotal research as scientists continue their exploration into fat and cholesterol metabolism!
Missouri Researchers Reveal Structure of Key Cholesterol Protein,ApoB100
Updated June 3,2025
Researchers at the University of Missouri have achieved a breakthrough in understanding “bad” cholesterol. They successfully mapped the detailed structure of ApoB100, a protein that plays a vital role in how low-density lipoproteins (LDL) transport cholesterol through the bloodstream. The findings, published in Nature, could pave the way for more effective treatments for high cholesterol and heart disease.
ApoB100 acts as a molecular scaffold, enveloping LDL particles and enabling their movement. By visualizing this structure, scientists hope to develop drugs that precisely target LDL, minimizing side effects often associated with current medications like statins.
Zachary Berndsen, an assistant professor in the MU School of Medicine, and Keith Cassidy, an assistant professor of biological physics, used cryo-electron microscopy to determine ApoB100S structure. The university’s investment in advanced equipment, including the Electron Microscopy Core at the Roy Blunt NextGen precision Health building and the Hellbender supercomputers, proved crucial.
“These cryo-electron microscopes allow us to see things at a much higher resolution,” Berndsen said. “Rather of just seeing a cell’s shape,as a notable example,these tools allow us to now see what individual proteins are shaped like.”
Cassidy further refined the protein’s image using artificial intelligence.”By integrating an AI neural network called AlphaFold with the cryo-electron microscopy images, we were able to get an even more detailed and higher-resolution picture of the structure of ApoB100,” Cassidy said. He added that while cholesterol is frequently enough viewed negatively, it is indeed essential for hormone production and cell function. Targeted treatments could reduce heart disease risks without disrupting these benefits.
Berndsen noted that current cholesterol tests lack specificity. He believes that measuring ApoB100 levels directly could provide a more accurate assessment of heart disease risk.Both researchers have personal connections to the research, citing family histories of heart disease.
“We are trying to bridge the gap between the basic science we are doing now and the applied health benefits down the road,” Berndsen said.
What’s next
The team plans to continue researching fat and cholesterol metabolism, with the goal of developing more precise testing methods and treatments for high cholesterol and related heart conditions.
