Hypothesis

Increased levels of HO-1 can lower blood pressure in diabetic spontaneously hypertensive rats.

Conclusion

The study found that upregulation of HO-1 and increased adiponectin levels can significantly reduce blood pressure and improve endothelial function in diabetic hypertensive rats.

Supporting Evidence

  • Treatment with SnCl2 increased HO-1 protein content and activity.
  • Blood pressure was significantly reduced in diabetic SHR treated with SnCl2.
  • Increased plasma adiponectin levels were observed after SnCl2 treatment.
  • Reduction in oxidative stress markers was noted in treated diabetic SHR.
  • Endothelial cell dysfunction was improved with HO-1 induction.

Takeaway

This study shows that a special protein called HO-1 can help lower blood pressure in diabetic rats by making their blood vessels healthier.

Methodology

Diabetic spontaneously hypertensive rats were treated with streptozotocin to induce diabetes and stannous chloride to upregulate HO-1, followed by measurements of blood pressure, oxidative stress markers, and endothelial function.

Participant Demographics

Male spontaneously hypertensive rats (SHR) and Wistar-Kyoto (WKY) rats, aged 180–220 g.
