Hypothesis
This study aims to determine the appropriate pharmacological interventions for each phase of diabetes development and the targeted therapeutic directions at different stages of diabetes progression.
Conclusion
A 12-week high-fat diet successfully induced stable insulin resistance in C57BL6 mice, leading to decreased motor activity and pathological damage in skeletal muscle and myocardium.
Supporting Evidence
- A continuous 12-week high-fat diet successfully induced stable insulin resistance in C57BL6 mice.
- Following insulin resistance, the motor activity of mice decreased.
- Pathological damage and functional decline were observed in the skeletal muscle and myocardium.
- The insulin signaling pathway was inhibited, resulting in reduced glucose transport.
- Mitochondrial dysfunction manifested as diminished ATP synthesis capacity.
Takeaway
Feeding mice a high-fat diet for a long time made them less able to use sugar for energy, which is not good for their health.
Methodology
C57BL6 mice were fed a high-fat diet for 12 weeks, and various tests were conducted to assess insulin resistance and its effects on skeletal muscle and myocardium.
Limitations
The study only included male mice, which may limit the generalizability of the findings.
Participant Demographics
64 male C57BL6 mice, 4 weeks old.
