Area of Science:

• Biomedical Engineering
• Cell Biology
• Pharmacology

Background:

• Oxidative stress plays a significant role in the pathogenesis of various respiratory diseases.
• Developing effective therapeutic strategies to combat oxidative stress is crucial for managing these conditions.

Purpose of the Study:

• To investigate the inhibitory potential of rutin-loaded liquid crystalline nanoparticles (LCNs) on oxidative stress in human bronchial epithelial cells (BEAS-2B).
• To analyze the effects of rutin-loaded LCNs on the expression of key antioxidant and pro-oxidant genes.

Main Methods:

• Human bronchial epithelial cells (BEAS-2B) were treated with rutin-loaded LCNs.
• Gene expression analysis was performed to quantify levels of antioxidant genes (NQO1, GCLC) and pro-oxidant genes (Nox4, Nox2B).

Main Results:

• Rutin-loaded LCNs significantly inhibited the expression of pro-oxidant genes (Nox2B and Nox4).
• A dose-dependent upregulation in the expression of antioxidant genes (Gclc and Nqo-1) was observed.
• These findings indicate a protective effect against oxidative stress.

Conclusions:

• Rutin-loaded LCNs demonstrate significant potential in mitigating oxidative stress.
• These nanoparticles represent a promising therapeutic strategy for respiratory diseases characterized by high oxidant loads.
