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 Rosmarinic acid is an ester of caffeic acid with interesting biological activities including antioxidant effects and scavenging of oxygen-free radicals. AIM To determine the potentially paradoxical effect of rosmarinic acid, typically being radioprotective when applied to non-tumorous cells, yet conversely displaying a sensitizing action when applied to metastatic B16F10 melanoma c...

Melanomas are highly lethal skin tumours that are frequently treated by surgical resection. However, the efficacy of such procedures is often limited by tumour recurrence and metastasis. Caveolin-1 (CAV1) has been attributed roles as a tumour suppressor, although in late-stage tumours, its presence is associated with enhanced metastasis. The expression of this protein in human melanoma developm...

7,7″-Dimethoxyagastisflavone (DMGF), a biflavonoid isolated from Taxus × media cv. Hicksii, induces apoptotic and autophagic cell death. However, whether DMGF suppresses tumor metastasis is unclear. The aim of this study was to investigate the anti-metastatic activities of DMGF on the metastatic processes of melanoma cells in vivo and in vitro. A transwell assay showed that DMGF could effective...

Abstract Introduction: Tregs in the tumor environment inhibit anti-tumor immunity and are critical targets for strategies. We previously showed that use surface lymphotoxin (LTαβ) PD-1 to signal LTβR PD-L1 on lymphatic endothelial cells, thereby promoting Treg migration. Most cells express PD-L1, yet interactions with LTαβ poorly studied. hypothesized couples signaling tumors regulate migration...

Carnosic acid is a natural benzenediol abietane diterpene found in rosemary and exhibits anti-inflammatory, antioxidant, and anti-carcinogenic activities. In this study, we evaluated the effects of carnosic acid on the metastatic characteristics of B16F10 melanoma cells. When B16F10 cells were cultured in an in vitro Transwell system, carnosic acid inhibited cell migration in a dose-dependent m...

Emerging evidence indicates a link between inflammation and cancer metastasis, but the molecular mechanism(s) remains unclear. Uteroglobin (UG), a potent anti-inflammatory protein, is constitutively expressed in the lungs of virtually all mammals. UG-knock-out (UG-KO) mice, which are susceptible to pulmonary inflammation, and B16F10 melanoma cells, which preferentially metastasize to the lungs,...

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...

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...
