Abstract
Cervical carcinoma poses a significant health threat, with traditional treatments proving inadequate in advanced stages. Curcumin, a bioactive compound derived from turmeric, exhibits notable anti-inflammatory, antioxidant, and antineoplastic properties, potentially modulating autophagy, and metastasis in cancer cells. This study examines curcumin's impact on autophagy and metastasis in cervical carcinoma, focusing on its interaction with autophagy-related gene 3 (ATG3). SiHa and HeLa cervical carcinoma cell lines were treated with curcumin, ATG3 knockdown (shATG3), and their combination. Cell migration was evaluated via wound healing assays, while cell proliferation was evaluated with CCK-8 assays. LC3 expression was assessed using immunofluorescence and western blotting. Molecular docking simulations identified curcumin's binding interactions with key proteins. Curcumin and shATG3 significantly inhibited both cell migration and proliferation, with a synergistic effect observed when combined. LC3 expression was enhanced, indicating increased autophagy. Docking studies revealed curcumin's potential binding to MMP2, MMP9, TGF-β, ATG3, LC3, and p62, suggesting modulation of these pathways. The combination of curcumin and ATG3 knockdown significantly inhibited cervical carcinoma cell migration and proliferation, while also enhancing autophagy, supporting the potential of curcumin as a therapeutic agent for cervical carcinoma. Further clinical research is needed to validate these findings.
