Hypothesis

Does the aqueous extract of Piper sarmentosum affect gene expression related to oxidative stress in human umbilical vein endothelial cells?

Conclusion

Piper sarmentosum reduces the expression of ICAM-1 and Nox4 while increasing antioxidant enzyme levels in endothelial cells.

Supporting Evidence

  • HUVECs treated with H2O2 showed a significant increase in ICAM-1 expression.
  • AEPS treatment reduced ICAM-1 and Nox4 expression in HUVECs.
  • AEPS increased the expression of antioxidant enzymes SOD1, CAT, and GPx.

Takeaway

Piper sarmentosum can help protect blood vessels by lowering harmful proteins and boosting the body's defenses against stress.

Methodology

Human umbilical vein endothelial cells were treated with hydrogen peroxide and Piper sarmentosum extract, followed by gene expression analysis using qPCR.

Limitations

The study could not determine the specific components of Piper sarmentosum responsible for the observed effects.

Participant Demographics

Human umbilical cord veins were used for cell culture.
