Cholesterol's effects on insulin-producing pancreatic cells
Effects of Cholesterol in Pancreatic Islets
This work looks at how cholesterol changes linked to statin use can harm insulin-making pancreatic beta cells in adults.

What this research studies
Researchers will study pancreatic islet beta cells (the cells that make insulin) in the lab to see how statins cause cholesterol to build up inside cell mitochondria. They will focus on cholesterol transport proteins called StAR and STARD3 that appear increased after statin exposure and test how changing these proteins affects mitochondrial cholesterol, insulin release, and cell survival. Experiments use isolated islets and molecular tools to raise or lower these transport proteins while measuring cell function, cholesterol levels, and markers of cell death. The goal is to understand the chain of events so we can point to ways to protect beta cells in people taking statins.
Who could benefit from this research
Good fit: Adults taking statin medications or adults at risk for type 2 diabetes would be most relevant to this research.
Not a fit: Children, people with type 1 diabetes, or patients not taking statins are unlikely to directly benefit from this project.
Why it matters
Potential benefit: If successful, the work could reveal targets to prevent statin-related loss of insulin production and lower the risk of new-onset type 2 diabetes.
How similar studies have performed: Previous clinical and laboratory studies show statins can raise diabetes risk and impair beta-cell function, but linking mitochondrial cholesterol accumulation and transport proteins like StAR/STARD3 is a newer, less-tested idea.
