Hypothesis
Does intermittent high glucose induce more apoptosis in beta cells compared to sustained high glucose?
Conclusion
Intermittent high glucose exposure leads to greater apoptosis in INS-1 cells than sustained high glucose, likely due to increased oxidative stress.
Supporting Evidence
- Intermittent high glucose caused a significant increase in apoptosis rates in INS-1 cells compared to stable high glucose.
- Oxidative stress levels were significantly higher in cells exposed to intermittent high glucose.
- Cell viability was significantly reduced in INS-1 cells exposed to intermittent high glucose.
Takeaway
When sugar levels go up and down a lot, it can hurt the cells that make insulin more than if the sugar stays high all the time.
Methodology
INS-1 beta cells were exposed to different glucose concentrations for 72 hours, and cell viability, apoptosis rate, and oxidative stress markers were measured.
