Abstract
Background and Purpose: It has been well-known both gold nanoparticles (AuNPs) and cisplatin are potential radiosensitizers for radiotherapy of cancer. In this in vitro study, we investigated the chemoradiotherapeutic effects of alginate nanogel co-loaded with AuNPs and cisplatin (ACA) on U87-MG human glioblastoma cells.
Methods: Based on the accomplished pilot studies, U87-MG cells were incubated with ACA and cisplatin at 10% inhibitory concentration (IC10) for 4h. Then, the cells were irradiated to different doses of 6MV X-rays (2 and 10 Gy). MTT assay was performed to evaluate the cell survival rate. Apoptosis was determined by flow cytometry using an annexinV–fluorescein isothiocyanate/propidium iodide apoptosis detection kit.
Results: The results showed that ACA at the concentration of 4 µg/ml (per cisplatin) and free cisplatin at concentration of 15 μg/ml have the same effects on U87-MG cells (survival rate: 90%). The combination of ACA with radiation resulted in a significant decrease in cell viability (survival rate: 30%). The flow cytometry assay also showed that such a combination therapy induces more apoptosis than necrosis.
Conclusion: It may be concluded that co-delivery of AuNPs and cisplatin with a single nanoplatform like ACA nanocomplex enhances the therapeutic ratio of human glioblastoma radiation therapy.
Keywords: Chemotherapy, radiotherapy, cisplatin, gold nanoparticles, apoptosis, U87-MG human glioblastoma cells.

Induction of cell death in cancer cells by modulating telomerase activity using small molecule drugs
Telomeres are distinctive but short stretches present at the corners of chromosomes and aid in stabilizing chromosomal makeup. Resynthesis of telomeres supported by the activity of reverse transcriptase ribonucleoprotein complex telomerase. There is no any telomerase activity in human somatic cells, but the stem cells and germ cells undergone telomerase ...read more
Signaling and enzymatic modulators in cancer treatment
Cancer accounts for nearly 10 million deaths in 2022 and is considered the leading cause of worldwide mortality. Cancer outcome can be improved through an appropriate screening and early detection and through an efficient clinical treatment. Chemotherapy, radiotherapy and surgery are the most important approach for the treatment of several ...read more
