Hypothesis
This study aimed to investigate the differential expression of the PI3K/AKT and TLR/NF-κB signaling pathways in an obese rat model.
Conclusion
A high-fat diet activates the PI3K/AKT and TLR-4/NF-κB signaling pathways in adipocytes, affecting metabolic health.
Supporting Evidence
- The Obs group exhibited significantly higher blood glucose and insulin levels compared to the Ctrl group.
- The GIR in the Obs group was significantly lower than that in the Ctrl group.
- Expression levels of p-PI3K and p-AKT proteins in the Obs group were significantly lower than those in the Ctrl group.
Takeaway
The study shows that feeding rats a high-fat diet makes them gain weight and affects how their bodies handle sugar and insulin.
Methodology
The study used a high-fat diet to induce obesity in Wistar rats and assessed metabolic changes through glucose tolerance tests and protein expression analysis.
Limitations
The study only assessed changes in body composition through relative weights of abdominal fat and skeletal muscle, lacking more precise analysis.
Participant Demographics
