Area of Science:

  • Biochemistry and Nanotechnology
  • Cancer Research
  • Pharmacology

Background:

  • Triple-negative breast cancer (TNBC) is aggressive, lacking hormone receptors and targeted therapy options.
  • Current chemotherapy for TNBC has limitations including toxicity, poor response rates, and high recurrence.
  • There is a critical need for innovative and more effective therapeutic strategies for TNBC.

Purpose of the Study:

  • To investigate the therapeutic potential of (E)-labda dial, a natural compound from Curcuma amada, formulated into nanoparticles for TNBC treatment.
  • To evaluate the efficacy and safety of (E)-labda dial-loaded nanoparticles compared to traditional chemotherapy.
  • To explore the interaction of (E)-labda dial with key mutant proteins in TNBC.

Main Methods:

  • Whole-genome sequencing identified TNBC mutations; molecular docking and dynamics simulations assessed (E)-labda dial interactions with mutant proteins (BRCA1, BRCA2, BARD1, PALB2, TP53, CHEK2).
  • Lipid-based nanoparticles (LNPs) and polymeric nanoparticles (PNPs) were developed, characterized for drug encapsulation, release kinetics, and stability.
  • Cytotoxic effects were evaluated using MTT assays, and in silico pharmacokinetic models predicted treatment outcomes.

Main Results:

  • Polymeric nanoparticles (PNPs) demonstrated superior encapsulation efficiency, sustained drug release, and tumor inhibition compared to LNPs.
  • Molecular docking revealed stronger binding of (E)-labda dial to mutant CHEK2, BARD1, and PALB2, suggesting disruption of carcinogenic pathways.
  • (E)-labda dial-loaded nanoparticles showed potential for targeted TNBC treatment with improved efficacy and reduced toxicity.

Conclusions:

  • Nanoparticle formulations of (E)-labda dial represent a promising targeted therapy for TNBC, potentially overcoming limitations of conventional chemotherapy.
  • This research provides a foundation for personalized and precision medicine approaches in TNBC treatment.
  • Further optimization and clinical validation are necessary to establish the translational potential of these nanoparticles in practice.
