Scientists discovered a new reason why people with type 2 diabetes struggle to control their blood sugar. They found that a protein called BAF60C becomes less active in the pancreas cells that normally manage blood sugar. When this protein is low, inflammation builds up and damages these cells. The good news? The researchers showed that exercise and a specific treatment can restore this protein’s function, reduce inflammation, and help the body control blood sugar better. This discovery opens a new door for treating type 2 diabetes by targeting this specific protein pathway.
The Quick Take
- What they studied: How a protein called BAF60C controls inflammation in the pancreas and affects blood sugar control in type 2 diabetes
- Who participated: The study used both human tissue samples from type 2 diabetes patients and laboratory mice fed a high-fat diet to mimic human diabetes
- Key finding: When BAF60C levels are low, inflammation increases and blood sugar control gets worse. When BAF60C is restored through treatment or exercise, inflammation decreases and blood sugar control improves significantly
- What it means for you: This research suggests that boosting BAF60C activity through exercise or future treatments could help people with type 2 diabetes better control their blood sugar. However, this is early-stage research, and more testing in humans is needed before new treatments become available
The Research Details
Researchers used a combination of approaches to understand how BAF60C works. They examined pancreas tissue from people with type 2 diabetes and compared it to healthy tissue, finding that BAF60C levels were lower in diabetic patients. They then created laboratory mice with low BAF60C to see what happened—these mice developed worse diabetes symptoms. Next, they created mice with extra BAF60C to test if boosting this protein helped—it did. Finally, they studied the exact molecular mechanism by which BAF60C controls inflammation, discovering it works by managing how quickly a specific inflammation-fighting protein (REG3B) is broken down in cells.
The researchers also tested whether exercise could activate this BAF60C pathway. They found that exercise in obese diabetic mice helped restore BAF60C function and improved blood sugar control. This suggests the pathway is responsive to lifestyle interventions, not just genetic factors.
This multi-layered approach—combining human tissue analysis, genetic manipulation in mice, molecular mechanism studies, and lifestyle intervention testing—provides strong evidence that BAF60C plays a central role in diabetes-related inflammation.
Understanding the specific mechanisms that cause diabetes is crucial for developing new treatments. Previous research knew that inflammation damages the pancreas cells that make insulin, but didn’t know exactly how this happens. By identifying BAF60C as a key control switch, researchers can now target this specific pathway with new drugs or lifestyle strategies, potentially offering better treatment options than currently available
This research was published in Developmental Cell, a respected scientific journal. The study used multiple complementary approaches (human tissue, genetic models, molecular analysis, and functional testing), which strengthens confidence in the findings. The researchers tested their findings in multiple ways and showed that restoring BAF60C through different methods (genetic overexpression, protein supplementation, and exercise) all produced similar beneficial results. However, because most experiments were done in mice rather than humans, results may not translate directly to people
What the Results Show
The main discovery is that BAF60C acts as a master control switch for inflammation in the pancreas. In people with type 2 diabetes and in mice with diet-induced diabetes, BAF60C levels drop significantly. When BAF60C is low, a harmful chain reaction starts: inflammation increases, the pancreas cells that produce insulin become damaged, and blood sugar control worsens.
When researchers increased BAF60C levels in diabetic mice, the opposite happened—inflammation decreased, pancreas cells functioned better, and blood sugar control improved. The improvement was substantial enough to partially reverse the effects of a high-fat diet that normally causes diabetes.
The researchers discovered exactly how BAF60C works at the molecular level. It partners with another protein (NPM1) to control how long a protective inflammation-fighting protein (REG3B) lasts in cells. By keeping REG3B levels high, BAF60C prevents excessive inflammation that damages insulin-producing cells.
Most importantly, the researchers showed that exercise—a proven diabetes treatment—works partly by restoring BAF60C function. This suggests that the BAF60C pathway is not just a genetic factor but something that can be influenced by lifestyle choices.
The research revealed that the communication between pancreas cells and immune cells (specifically macrophages) is disrupted in diabetes, and BAF60C controls this communication by regulating REG3B secretion. When BAF60C is restored, this cell-to-cell communication improves, reducing harmful inflammation. The study also showed that directly supplementing REG3B protein (the downstream target of BAF60C) improved diabetes symptoms in mice, suggesting this could be a potential therapeutic approach even if BAF60C itself cannot be easily targeted
Previous research established that inflammation in the pancreas contributes to type 2 diabetes, but the specific mechanisms were unclear. This study fills that gap by identifying BAF60C as a previously unknown key regulator. The finding that exercise works through this pathway aligns with extensive evidence that exercise helps diabetes, but provides a new molecular explanation for why exercise is effective. The research also connects nucleolar stress (stress in the cell’s protein-making factory) to diabetes for the first time, opening a new area of investigation
The study has several important limitations. Most experiments were conducted in mice, and mouse biology doesn’t always match human biology exactly. The human tissue samples were limited in scope and didn’t allow researchers to test whether treatments would work in actual patients. The study doesn’t explain why BAF60C levels drop in the first place during diabetes development. Additionally, the research doesn’t address whether BAF60C changes are a cause or a consequence of diabetes—it’s possible that diabetes causes BAF60C to drop rather than BAF60C dropping causing diabetes. Finally, while exercise was shown to help, the study didn’t test other potential ways to boost BAF60C in living organisms
The Bottom Line
Based on this research, people with type 2 diabetes should continue or start regular exercise, as it appears to activate the BAF60C pathway and improve blood sugar control (high confidence, supported by extensive existing evidence). This study does not yet support any new medications or supplements, as human testing has not been done. Anyone with type 2 diabetes should work with their healthcare provider on proven treatments like medication, diet, and exercise while researchers continue developing BAF60C-targeted therapies (moderate confidence for future applications)
This research is most relevant to people with type 2 diabetes or those at high risk for developing it. It’s also important for researchers developing new diabetes treatments and for healthcare providers looking for new therapeutic targets. People with other inflammatory conditions might eventually benefit if similar mechanisms are found in their diseases. This research is NOT yet ready to change treatment recommendations for the general public
Exercise can improve blood sugar control within weeks to months (based on existing research). Any new BAF60C-targeted medications are likely years away from human testing and approval. If new treatments are developed, it will probably take 5-10 years before they become available to patients
Want to Apply This Research?
- Track weekly exercise minutes and fasting blood glucose levels together to monitor the relationship between activity and blood sugar control. Users could log 30-minute exercise sessions and measure blood glucose before and after exercise to see personal patterns
- Set a goal to do 150 minutes of moderate exercise per week (about 30 minutes, 5 days per week), as this appears to activate the BAF60C pathway. Users could use the app to schedule exercise sessions, track completion, and receive reminders
- Monitor blood glucose trends monthly while maintaining consistent exercise habits. Users should track whether their average blood glucose readings improve over 8-12 weeks of regular exercise, which would indicate the BAF60C pathway is being activated
This research describes laboratory findings in mice and human tissue samples, not proven treatments for humans. While the results are promising, they have not yet been tested in human clinical trials. People with type 2 diabetes should continue following their doctor’s treatment recommendations and not make changes based solely on this research. Anyone considering new diabetes treatments or significant lifestyle changes should consult with their healthcare provider first.
