Abstract
Abstract Monocyte chemo-attractant protein (MCP-1) is a chemokine, which recruits monocytes, neutrophils, and lymphocytes in response to trauma and proinflammatory cytokines such as TNF-α. MCP-1 generally is not expressed in healthy individuals, but in response to various stressful stimuli it gets up-regulated, which in turn contributes to increased inflammation. MCP-1 has been implicated in mediating apoptosis by producing a proapoptotic protein designated MCP-induced protein (MCPIP). Resveratrol (RES), a polyphenolic compound found in the skin of red fruits, exhibits anti-inflammatory, anti-oxidative, anti-cancer, and anti-proliferative characteristics. In this study, we hypothesized that the functionalization of RES with detonated nano-diamond (DND, hereafter called fDND) will enhance the effective delivery of RES to tumor cell and impact the modulation of molecular mechanisms in murine prostate cancer (PCa) cells. This hypothesis was tested on mouse PCa cell lines, derived from transgenic adenocarcinoma of mouse prostate (TRAMP), in C57/B6 mice. Interestingly, TRAMP-C1 and TRAMP-C2 form tumor while TRAMP-C3 fails to develop tumor. TRAMP cells were treated with different concentrations of fDND at different time points and analyzed for underlying cellular and molecular mechanisms such as cell viability/proliferation, mitochondrial membrane potential, cytokines and growth factors production. The initial results indicate that the fDND significantly induce molecular signatures in TRAMP-C3 cells in comparison with TRAMPC1 and C2. Interestingly, the level of MCP-1 was significant elevated in TRAMP C1 and C2 cells. Thus, suggesting a major role of MCP-1 in the regulation of cancer progression and clearance. This data also suggest that the functionality of dietary compounds can be enhanced by conjugating or functionalizing them with DND, which can be used as a therapeutic carrier.
