Abstract

Objective: Investigate the anti-cancerous potential of garlic-derived nanovesicles (GDNVs), exploring their cytotoxic effects on HeLa and PC-3 cell lines, and elucidate the underlying mechanisms, including apoptosis induction and inhibition of epithelial-mesenchymal transition (EMT). Methods: GDNVs were isolated using differential centrifugation and ultracentrifugation. Characterization was performed through dynamic light scattering (DLS), field-emission scanning electron microscopy (FESEM), and Fourier-transform infrared spectroscopy (FTIR). Cytotoxicity assessments on HeLa and PC-3 cell lines using MTT assay. Apoptosis induction was evaluated through nuclear morphology changes and quantification of apoptotic cells using DAPI and PI/annexin V analysis. Western blot of apoptosis-related proteins (bcl-2, bax, caspase-3) was analysed. Anti-metastatic potential was assessed using wound healing assay and EMT transition inhibition. Results: Garlic-derived nanovesicles (GDNVs), characterized by a size of 134.2 nm, demonstrated a substantial and dose- as well as time-dependent anti-proliferative impact on HeLa and PC-3 cell lines. The induction of apoptosis was unequivocally established through discernible modifications in nuclear morphology. The apoptotic cell count in HeLa and PC-3 cells increased by 42.4 ± 4.2% and 38.2 ± 3.2%, respectively. Comprehensive Western blot demonstrated alterations in the expression of key apoptotic regulators, namely bcl-2, bax, and caspase-3, providing robust evidence for the initiation of apoptosis. Furthermore, GDNVs exerted a significant inhibitory effect (p < 0.001) on the migratory potential of both HeLa and PC-3 cells. Moreover, there was a discernible association between GDNVs and the suppression of Epithelial-Mesenchymal Transition (EMT), emphasizing their role in impeding the metastatic potential of these cancer cell lines. Conclusion: This study establishes, for the first time, the anti-cancerous potential of GDNVs. The observed dose- and time-dependent anti-proliferative effects, selective cytotoxicity, apoptosis induction, and anti-migratory potential highlight GDNVs as a promising candidate for cancer treatment.
