Project description:Gene expression was studied in melanoma cell lines with (SKMEL-23 and SKMEL-1128) or without (A375 and CLOL800) ALKATI expression. Effects on gene expression was also analyzed after knockdown of NIPBL in melanoma cell lines 501mel, COLO800 and A375
Project description:To understand the transcriptional impact of FOXD3 in melanoma cells, we utilized a microarray approach. We collected RNA from three unrelated mutant B-RAF melanoma cell lines (WM115, WM793, and A375) that were engineered to inducibly express FOXD3 or the control gene, ?-galactosidase (LacZ), after 5 days of transgene induction. This time point was chosen based on maximal phenotypic changes previously observed. Comparison of gene signatures between the 3 cell lines produced approximately 2,600 common genes differentially regulated by FOXD3-expressing cells compared to the LacZ controls. Three unrelated mutant B-RAF melanoma cell lines (WM115, WM793, and A375) were induced to express FOXD3 and compared against the same cell lines expressing the control gene, ?-galactosidase (LacZ).
