چکیده مقاله:

Introduction: The increasing trend of cancer morbidity and mortality is a major human health concern, indicating the necessity for the design and introduction of novel anticancer compounds. The use of nanotechnology products is a new approach to cancer treatment. Therefore, the current study was performed to synthesize Titanium Dioxide nanoparticles (NPs) functionalized with glutamine and conjugated to Thiosemicarbazide (TiO۲@Gln-TSC) to inhibit the proliferation of liver cancer cells line (HepG۲) and evaluate the effect of TiO۲@Gln-TSC NPs on the expression of apoptotic genes. Material & Methods: TiO۲@Gln-TSC NPs were synthesized by a chemical method and characterized by Fourier-transform infrared spectroscopy (FT-IR), Energy-dispersive X-ray spectroscopy (EDS), Scanning electron microscopy (SEM), and Transmission electron microscopy (TEM). The cytotoxicity of the Titanium Dioxide nanoparticles was evaluated by the MTT assay, and relative gene expression was studied by Real Time PCR method. Findings: The results showed that the synthesized Titanium Dioxide nanoparticles were spherical with a size range of ۵۹ to ۸۲ nm. The particles had a considerable anti-proliferative effect on liver cancer cells line with IC۵۰ of ۸۰ µg/mL. The treatment of the cancer cell line with TiO۲@Gln-TSC NPs significantly increased the expression of the CASP۳, BAX, and BCL۲ by ۲.۸, ۲.۷, and ۱.۳ folds, respectively, which indicated the activation of apoptotic pathways in the treated cells. Discussion & Conclusion: The results showed that the TiO۲@Gln-TSC NPs could inhibit the proliferation of liver cancer cells line and by triggering the apoptosis pathway.
