Rutin-loaded liquid crystalline nanoparticles attenuate oxidative stress in bronchial epithelial cells: a PCR validation.

Aim: In the present study, the inhibitory potential of rutin-loaded liquid crystalline nanoparticles (LCNs) on oxidative stress was determined in human bronchial epithelial cells (BEAS-2B) by analysing the expression levels of different antioxidant (NADPH quinine oxidoreductase-1 (NQO1); γ-glutamyl cysteine synthetase catalytic subunit (GCLC)) and pro-oxidant (NADPH oxidase (Nox)-4; Nox2B) genes.

Results

Our findings revealed that the rutin-loaded LCNs inhibited the genes, namely Nox2B and Nox4, which caused oxidative stress. In addition, these nanoparticles demonstrated an upregulation in the expression of the antioxidant genes Gclc and Nqo-1 in a dose-dependent manner.

Conclusion

The study indicates the promising potential of rutin-loaded LCNs as an effective treatment strategy in patients with high oxidant loads in various respiratory diseases.
