    摘要: Metastasis of melanoma cells during the recurrence or the late stage of melanoma has been characterized as the dissemination of tumor cells under anchorage independency. The secreted interleukin-8 (IL-8) and its conical receptors from melanoma cells have been associated with melanoma malignancy. However, their correlations with melanoma cells under anchorage independency were unclear. Suspension of adherent melanoma cells generated the suspended melanoma cell model of anoikis resistance. The in-vivo xenograft experiment, in-vitro cell proliferation/migration assay, microarray, and bioinformatics analysis were used to compare the malignancy and gene expression profiling in adherent and suspended melanoma cells. PCR, enzyme-linked immunosorbent assay, immunohistochemistry, and kinase inhibition assay were adapted to validate the expression and regulation of IL-8 and CXCR1/2. Suspended melanoma cells were anoikis resistant and showed elevated malignancy in vivo and in vitro. Gene expression profiling of adherent and suspended melanoma cells showed extensive alteration associated with cell survival/death, cell signaling, and regulation of gene expression. Microarray and bioinformatics analysis on gene set enrichment analysis further showed elevated IL-8 expression in suspended melanoma cells. The upregulation of IL-8 and the effect on chemotaxis were mediated by MEK/ERK activation upon cell suspension. Change in JNK phosphorylation induced CXCR1 downregulation under cell suspension, but upregulation by cell reattachment. We suggest the possible roles of elevated IL-8 secretion and change in CXCR expression contributing toward elevated melanoma malignancy upon reattachment from cell suspension. We show that the suspension of melanoma cells is critical in promoting melanoma malignancy in vivo and in vitro.
