Abstract
The importance of biogenic silver/silver chloride nanoparticles has become increasing day by day. In the present study, silver/silver chloride nanoparticles (Ag/AgCl-NPs) were synthesized from Kaempferia rotunda tuberous rhizome extract to evaluate the antiproliferative activity against human glioblastoma stem cells (GSCs) in vitro and Ehrlich ascites carcinoma (EAC) cells in vivo in mice. Synthesis of nanoparticles was confirmed by colour change and UV-visible spectrum and characterized by TEM, XRD, TGA, AFM and FTIR. K rotunda and recently synthesized Zizyphus mauritiana fruit extract-mediated Ag/AgCl-NPs inhibited 77.2% and 71% of GSCs growth at 32 µg/mL concentration with the IC values of 6.8 and 10.4 µg/mL, respectively. Cell morphological studies and caspase-3 immunofluorescence assay revealed that both biogenic nanoparticles induced apoptosis in GSCs. Expression levels of several genes were checked by real-time PCR after treatment with K rotunda tuberous rhizome-mediated Ag/AgCl-NPs. PARP, EGFR, NOTCH2 and STAT3 gene expression were decreased with the increase of NFκB, TLR9, IL1, TNFα, IKK and p21 gene that would be the cause of induction of apoptosis in GSCs. The cell cycle arrest at G /M phase was confirmed by flow cytometric assay. Both nanoparticles were injected intraperitoneally to rapidly growing EAC cells for 5 consecutive days. Approximately, 32.3% and 55% EAC cells growth were inhibited by K rotunda tuberous rhizome-mediated Ag/AgCl-NPs at 6 and 12 mg/kg/day doses, respectively while only 20% cell growth inhibition was monitored at 12 mg/kg/day dose of Z mauritiana-mediated Ag/AgCl-NPs. From the above results, it can be concluded that presently synthesized nanoparticles would be a potent anticancer agent.
