| Summary: | Siberian ginseng, perennial herb belongs to Araliaceae family used in traditional medicines to treat hypertension, thrombus, inflammation and cancer. In the present study, we biosynthesized goldnanoparticles using Siberian ginseng aqeous extract in a cost effective manner. The synthesized Siberian ginseng gold nanoparticle (SG-GNPs) were characterized using UV-Vis spec, HR-TEM, XRD, FTIR, SAED analysis. UV-Vis spectroscopic analysis showed a surface Plasmon resonance peak at 538 nm which does not reduce till 30 days of incubation. The results of HR-TEM, XRD and SAED confirm the spherical shape, crystalline nature and the size of the synthesized gold nanoparticles. The FTIR results prove that the biological components present in the Siberian ginseng had reduced the gold ions to synthesis gold nanoparticles. After characterization, the efficacy of SG-GNPS against the melanoma, a deadliest skin carcinoma, was assessed in vitro using B16 murine melanoma cells. The CC50 dose of SG-GNPs against B16 cells were assessed with MTT assay and the anticancer activity was evaluated using Rhodamine 123, H2DCFDA and dual staining techniques. The induction of apoptosis by SG-GNPs against melanoma cells were confirmed with q-PCR analysis. The results of staining techniques prove that SG-GNPs increase the reactive oxygen species and decreased the mitochondrial membrane potential. It is further confirmed by the results of q-PCR analysis which shows increased apoptotic Bid, Bad, Casp3, Casp 9 genes and decreased antiapoptotic Bcl2 gene expression in SG-GNPs treated cells. Our results authentically prove the biosynthesized SG-GNPs induces apoptosis in melanoma cells and it possesses anticancer property. |
