In their study of the molecular effects of low dose of 5AzadC (Decitabine) on 8 melanoma cell lines, Halaban et al.[24] presented evidence for changes in expression of COL1A2, TNFRSF10D, THBS1 and UCHL1. Here, we further document the link between these genes and melanoma by confirming the correlation between methylation and expression of these genes in a larger panel of melanoma cell lines. This evidence concerns the gene THBS1 and melanoma.
