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...

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...

Background: Melanoma is a common and malignant cutaneous tumor, which is responsible for a large proportion of skin cancer deaths. Dendritic cell (DC)-based vaccines have achieved positive results in the treatment of melanoma because of their ability to induce cytotoxic response to facilitate tumor elimination. Objective: To improve the efficacy of dendritic ce...

cancer is the second important reason of mortality in the world. in this regard melanoma was accounted as the most aggressive type of coetaneous cancer. among drug extracted from natural products from marine organisms have been focused investigations related to chemotherapeutic agents derived from echinoderms such as sea cucumbers and starfish.  in the present study, cytotoxic and apoptosis ind...

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...

It has been known that melanoma cells can suppress the immune system by the Fas ligand. The present study investigated whether interleukin (IL)-18, which can enhance Fas ligand expression, is produced by B16F10 melanoma cells and is involved in immune escape of tumor cells. Immunohistology, reverse transcription-PCR, intracellular fluorescence-activated cell-sorting analysis, and immunoblotting...

Melanoma is one of the most deadly skin cancers. T-cadherin is an atypical member of the cadherin superfamily as it lacks the transmembrane and cytoplasmic domains and is anchored to cell membranes through glycosylphosphatidylinositol (GPI) anchors. T-cadherin downregulation is associated with a poorer prognosis in various carcinomas, such as lung, ovarian, cervical and prostate cancer, while i...

PRDM (PRDI-BF1 and RIZ domain-containing) proteins constitute a family of zinc finger proteins and play important roles in multiple cellular processes by acting as epigenetic modifiers. PRDM5 is a recently identified member of the PRDM family and may function as a tumor suppressor in several types of cancer. However, the role of PRDM5 in murine melanoma remains largely unknown. In our study, ef...
