BACKGROUND Previous work has demonstrated that vitamin E succinate (VES), an ester analogue of vitamin E, inhibits the growth of melanoma in vitro. However, there is no information about the effect of VES on melanoma in vivo. We investigated the effect of VES on melanoma in vitro and in vivo. METHODS The effect of VES on the proliferation and apoptosis of the B16F10 murine melanoma cell line ...

Most cancer cells preferentially rely on glycolysis to produce the energy (adenosine triphosphate, ATP) for growth and proliferation. Emerging evidence demonstrates that the apoptosis in cancer cells could be closely associated with the inhibition of glycolysis. In this study, we have found that jolkinolide B (JB), a bioactive diterpenoid extracted from the root of Euphorbia fischeriana Steud, ...

Cytokine-based and antibody-targeted immunotherapies have both been important approaches in the treatment of malignant cancers. However, combinational therapies of cytokines and tumor-targeting antibodies remain to be further explored, especially in advanced solid tumors. In this study, C57BL/6 mice bearing established subcutaneous B16F10 melanoma were treated with mouse melanoma targeting anti...

Peptides are the end product of transcript processing, for example allow great viral adaptations and their transfection between species arising pandemic threats or diseases devoid nucleic acid like prions. So, because high specificity, peptides can be used different therapeutic goals. In this work we describe in vitro action a peptide named G10S sequence is part group previously selected by ExP...

Cytotoxic activity profiling of the n-hexane extract from fruit pulp Ginkgo biloba L. (Gingkgoaceae) led to purification 8 compounds. HPLC based identified a cytotoxic alkenylresorcinol. The was further separated by time-based fractionation in gradient condition, and cytotoxicity each fraction evaluated using 293, B16F10, BJAB, HCT116 cancer cells vitro. Bilobol isolated as an active constituen...

IL-27 is a novel IL-6/IL-12 family cytokine playing an important role in the early regulation of Th1 responses. We have recently demonstrated that IL-27 has potent antitumor activity, which is mainly mediated through CD8(+) T cells, against highly immunogenic murine colon carcinoma. In this study, we further evaluated the antitumor and antiangiogenic activities of IL-27, using poorly immunogeni...

Abstract Modulating tumor-infiltrating immune cells is the key mission for development of cancer immunotherapy. Based on recent literature and our bioinformatic analysis, nuclear receptor subfamily 4 group A member 1 (NR4A1) an ideal target immunotherapy due to its important role in T cell exhaustion, regulatory (Treg) function. Here we targets NR4A1 via proteolysis-targeting chimeric (PROTAC) ...

In mammalian melanocytes, melanosome is a highly specialized organelle where melanin is synthesized. Melanin synthesis is controlled by tyrosinase, the vital enzyme in melanogenic pathway. The present investigation is based on an effect of purified mushroom tyrosinase of Agaricus bisporus on B16F10 melanocytes for the melanin production via blocking pigment cell machinery. Using B16F10 melanocy...

In this study, we demonstrate that an effective immune response against prostate tumors in mouse tumor model can be elicited using a strategy that combines CTLA-4 blockade and pSLC-3P-Fc-modified tumor cell vaccine (named B16F10-SLC-3P-Fc). Treatment of B16F10-3P-bearing mice resulted in a significant reduction in tumor incidence as assessed 2 months after treatment. In vivo Ab depletion confir...

Evaluation of [99mTc]oxotechnetium(V) complexes of the amine-amide-dithiol (AADT) chelates containing tertiary amine substituents as small-molecule probes for the diagnostic imaging of metastatic melanoma has shown that technetium-99m-labeled AADT-(CH2)2-NEt2 (99mTc-1) has the highest tumor uptake and other favorable biological properties. We have, therefore, assessed this agent in a more reali...
