Gold-Coated Glybosomes Mimicking Physiological Micelles for ROS-Mediated Photothermal Ablation against Cervical...

Area of Science:

• Biochemistry
• Nanotechnology
• Oncology

Background:

• Lithocholic acid (LCA), a hydrophobic bile acid, plays roles in bile metabolism and signaling via receptors like FXR, GPBAR, and VDR.
• LCA exhibits anti-inflammatory, antimicrobial, and anticancer properties.
• Emerging research highlights LCA's potential in modulating cell signaling pathways.

Purpose of the Study:

• To develop gold-coated Glybosomes (Au@GLB) using lithocholic acid as a photothermal agent.
• To evaluate the efficacy of Au@GLB nanoparticles against cervical cancer.
• To investigate the underlying mechanisms of Au@GLB-induced cell death.

Main Methods:

• Facile synthesis of Glybosomes (GLBs) encapsulating lithocholic acid.
• Coating of GLBs with gold nanoparticles to form Au@GLB.
• Assessment of cytotoxicity, biocompatibility, and hemocompatibility of Au@GLB.
• Mechanistic studies involving reactive oxygen species (ROS) generation, mitochondrial membrane potential, and DNA damage assays.

Main Results:

• Developed Au@GLB nanoparticles demonstrated enhanced cytotoxicity against cervical cancer cells.
• The formulation exhibited good biocompatibility and hemocompatibility.
• Au@GLB treatment promoted apoptosis via ROS generation, mitochondrial dysfunction, and DNA damage.

Conclusions:

• Au@GLB nanoparticles represent a promising nanoformulation for cervical cancer treatment.
• The study validates the potential of lithocholic acid-based nanostructures in photothermal therapy.
• Au@GLB NPs offer an effective strategy for inducing cancer cell death through multiple mechanisms.
