The increased incidence of cancer in recent years is associated with a high rate of mortality. Numerous types of cancer have a low percentage of CD133(+) cells, which have similar features to stem cells. The CD133 molecule is involved in apoptosis and cell proliferation. The aim of this study was to determine the biological effect of CD133 suppression and its role in the chemosensitization of c...

The macrophage migration inhibitory factor (MIF)-homologue D-dopachrome tautomerase (D-DT) recently has been described to have similar functions as MIF. However, the role of D-DT, as opposed to MIF, in tumor biology remains unknown. We hypothesized that D-DT could represent a target for therapeutic interventions in cancer. We analyzed the production of D-DT in the murine melanoma model B16F10 a...

Studies have shown that the 26S proteasome is involved in cell cycle control, transcription, DNA repair, immune response and protein synthesis. In the present study, we investigated the antiproliferative effects of the proteasome inhibitor bortezomib and heat shock protein (Hsp)70 inhibitors on the B16F10 melanoma cell line. The IC50 value of bortezomib was found to be 2.46 nM, while that of th...

Solid tumors show a trend to develop immunosuppressive microenvironment and a dynamic cell composition along tumor progression. Various types of non-immune and immune cells constitute solid tumor. Understanding the change of cellular constituents and their function is pertinent to understand tumor immune status, which enables rational design of cancer immunotherapy. Given the complexity of tumo...

Genistein is one of the main components of soy-based foods, which are widely known for their many benefits, including anti-cancer, anti-inflammatory, and antioxidant effects. In this study, we investigated the anti-metastasis effects of genistein on B16F10 melanoma cells. Our results showed that genistein strongly inhibited B16F10 cell proliferation and induced apoptosis in time- and concentrat...

This study explored the role of ubiquitin C-terminal hydrolase-L1 (UCH-L1) in the production of ROS and tumor invasion. UCH-L1 was found to increase cellular ROS levels and promote cell invasion. Silencing UCH-L1, as well as inhibition of H2O2 generation by catalase or by DPI, a NOX inhibitor, suppressed the migration potential of B16F10 cells, indicating that UCH-L1 promotes cell migration by ...

Polyploidization of Meth-A and B16-F10 cells by demecolcine was examined using flow cytometry (FCM). In the presence of demecolcine, both cell lines were polyploidized to more than 16c DNA content. A marked difference was observed in the durations of S phase of polyploidy. The S-phase duration of Meth-A cells was doubly increased with ploidy, but that of B16F10 cells remained constant. When the...

Metastatic melanoma is a fatal disease that responds poorly to classical treatments but can be targeted by T cell-based immunotherapy. Cancer vaccines have the potential to generate long-lasting cytotoxic CD8(+) T cell responses able to eradicate established and disseminated tumors. Vaccination against antigens expressed by tumor cells with enhanced metastatic potential represents a highly attr...

Background: Pistacia is a genus of flowering plants from the Anacardiaceae family that grows in different parts Iran. This has pharmacological activities, including antioxidant, antimicrobial, anti-mutagenic, and anti-inflammatory activities. Objectives: In this study, we investigated anti-melanogenic effect extracts essential oil unripe fruits P. atlantica subsp. Kurdica on B16F10 cell line. M...
