Chitosan coated iron nanoparticles were synthesized by co-precipitation method and also Nanoparticles evaluate the effect of surface coating on stability toxicity nanoparticles. FTIR amino groups acted as a capping site for Iron stabilization. Invitro cytotoxicity is dependent dose-based their reduction was observed in SKMEL cancer cells administered with different concentration samples. I50 va...

Melanoma is the most aggressive skin-cancer, showing high mortality at advanced stages. Platelet Derived Growth Factor Receptor-alpha (PDGFR-alpha) potently inhibits melanoma- and endothelium-proliferation and its expression is significantly reduced in melanoma-biopsies, suggesting that melanoma progression eliminates cells expressing PDGFR-alpha. In the present study transient overexpression o...

Melatonin has been shown to have oncostatic effects on malignant melanoma in vitro and in vivo. We studied the growth suppressive effects of melatonin over a wide range of concentrations in four melanoma cell lines (SBCE2, WM-98, WM-164 and SKMEL-188) representative for different growth stages and phenotype. Melanoma cells were incubated with melatonin 10(-12)-10(-3) M, and proliferation and cl...

Despite Polygonum multiflorum (PM) has been experiencely used as a drug to treat early graying hair phenomenon in Asian countries for a long time, there is limited study examined the real biological effects of PM on hair graying in vitro and in vivo. In this study, we investigated the effects of PM root extract (PM-RE) on melanin synthesis in human melanoma SKMEL-28 cells and embryos/larvae of ...

Spectroscopic, photochemical and biological properties of indocyanine green (ICG) are presented. Light over 800 nm is effectively absorbed by ICG. This property as well as photochemical behaviour of ICG make it a very suitable dye for photodynamic treatment of melanoma cells. Cytotoxicity of ICG itself and the effect of photodynamic therapy (PDT) were evaluated by following the growth of human ...

the present study was designed to investigate the anti-melanogenic and cytotoxic activities of methanol extract of phlomis kurdica. the antioxidant and anti-tyrosinase activity of meoh extract from p. kurdica (mpk) were examined by dpph radical scavenging and mushroom tyrosinase activity assays (in vitro), respectively. furthermore, the effect of mpk on the melanin content, cellular tyrosinase ...

We investigated the efficacy of Alisertib (ALS), a selective Aurora kinase A (AURKA) inhibitor, in melanoma. We found that ALS exerts anti-proliferative, pro-apoptotic, and pro-autophagic effects on A375 and skmel-5 melanoma cells by inhibiting p38 MAPK signaling. SB202190, a p38 MAPK-selective inhibitor, enhanced ALS-induced apoptosis and autophagy in both cell lines. ALS induced cell cycle ar...

Recombinant human macrophage colony-stimulating factor (rhM-CSF) was given to cynomolgus monkeys by continuous intravenous infusion or subcutaneous injection, at a dose of 50 to 100 micrograms/kg/d in repetitive 14-day cycles. Starting within 24 to 48 hours of initiation of rhM-CSF, there was a progressive increase in the number of circulating monocytes, from a baseline of 811 +/- 253 cells/mic...

A family of cell surface glycoproteins with a molecular weight of 96,000 (gp96) has recently been implicated in the individually distinct immunogenicity of chemically induced sarcomas of inbred mice. Rabbit antiserum to murine gp96 detects an antigenically related M, 96,000 cell surface glycoprotein on two cultured human melanoma cell lines, SKMEL-13 and SK-MK1 -177. Molecular probes for 5' and...
