Objective(s): In previous studies, antioxidant activity of Viola odorata L. has been demonstrated. In this study, we have investigated the anti-melanogenic effect of extract and fractions of the plant in B16F10 cell line. Materials and Methods: Impact of different increasing concentrations of extract and fractions of V. odorata was evaluated on cell viability, cellular tyrosinase, melanin conte...

objective: recent evidences suggest that tumors arise from a small subpopulation of cells, the cancer stem cells (cscs) or tumor initiating cells. cscs are able to resist the conventional methods of cancer therapy due to existence of abc transporters on their surface. this leads to csc resistance and maintenance resulting in post-treatment relapse and metastasis. therefore, precise identificati...

Nepeta glomerulosa Boiss. is a medicinal plant has been used in traditional medicine. The aim of this study was to evaluate the anti-melanogenesis inhibitory activity of MeOH, n-hexane, ethyl Acetate (EtAc), dichloromethane (CH2Cl2), n-butanol (BuOH) and H2O extracts isolated from N. glomerulosa in B16 melanoma cell line. The B16F10 cell line viability after treatment with increasing concentrat...

nepeta satureioides boiss. has been used in traditional medicine of eastern countries and is famous for its medicinal properties. the aim of this study was to evaluate the effect of methanol (meoh), n -hexane and dichloromethane (ch 2 cl 2 ) fractions of the extract on melanin synthesis and oxidative stress in b16f10 melanoma cell line. the b16f10 cell line viability after treatment with increa...

Previosuly, we reported the cytotoxic effect of colloidal silver (AgC) on MCF-7 breast cancer cell line. However, there is scarce information on its antitumor potential. The aim of this study was to evaluate the anti-tumoral activity of colloidal silver (AgC) or silver nanoparticles (AgNPs) in a B16F10 melanoma mice model. In vitro, B16F10 cells were treated with different concentrations of AgC...

Genetic instability is recognized as an important aspect of the devel opment of tumor heterogeneity and malignancy. In a previous study [Hill et al. Science (Wash. DC), 244: 998-1001, 1984), we demonstrated that metastatic variants are generated at a more rapid rate in the highly metastatic B16F10 mouse melanoma cell line than in the less metastatic B16F1 cell line. The metastatic variants were...

BACKGROUND/AIM Vitamin A (all- trans -retinol, ATRol) serves as a precursor for all- trans -retinoic acid (ATRA), a ligand for the retinoic acid receptor (RAR), representing a potent regulator for many physiological processes. While murine melanoma cells are highly sensitive to retinoid treatment, human melanoma cells have developed still unidentified mechanisms that mediate cellular retinoid r...

Merlin, the protein product of the neurofibromatosis type 2 gene (NF2) acts as a tumor suppressor in mice and humans. In this study, melanoma B16F10 cells were engineered to overexpress the NF2 gene by establishing stable transductants. A cell line overexpressing Merlin (B16F10-M) was generated. When compared to the parental cells, the B16F10-M cells demonstrated differences in their cell surfa...
