Abstract:
Although arbutin is a natural product and widely used as an ingredient in skin care products, its effect on the gene expression level of human skin with malignant melanoma cells is rarely reported. We aim to investigate the genotoxic effect of arbutin on the differential gene expression profiling in A375 human malignant melanoma cells through its effect on tumorigenesis and related side-effect. The DNA microarray analysis provided the differential gene expression pattern of arbutin-treated A375 cells with the significant changes of 324 differentially expressed genes, containing 88 up-regulated genes and 236 down-regulated genes. The gene ontology of differentially expressed genes was classified as belonging to cellular component, molecular function and biological process. In addition, four down-regulated genes of AKT1, CLECSF7, FGFR3, and LRP6 served as candidate genes and correlated to suppress the biological processes in the cell cycle of cancer progression and in the downstream signaling pathways of malignancy of melanocytic tumorigenesis.

- * To analyze the impact of arbutin on tumorigenesis and related side effects at the gene expression level.
- * To identify differentially expressed genes and candidate genes involved in melanoma progression.
Main Methods:
- * DNA microarray analysis was employed to profile gene expression.
- * A375 human malignant melanoma cells were treated with arbutin.
- * Differential gene expression patterns were analyzed, including gene ontology classification.
Main Results:
- * Arbutin treatment resulted in significant differential gene expression in 324 genes (88 up-regulated, 236 down-regulated).
- * Gene ontology analysis revealed involvement in cellular component, molecular function, and biological processes.
- * Four key down-regulated genes (AKT1, CLECSF7, FGFR3, LRP6) were identified as potential suppressors of cancer progression.
Conclusions:
- * Arbutin influences the differential gene expression profile of malignant melanoma cells.
