title: Regulation of melanotransferrin gene in melanoma cells. Analysis of the enhancer region.
abstract: The human iron-binding protein melanotransferrin is up-regulated in most skin melanomas. With the goal to understand the mechanisms controlling the expression of the gene in these tumor cells, we previously reported the identification of an enhancer exhibiting melanoma specificity. We show here that, in the highly expressing SK-MEL-28 melanoma cell line, the chromatin structure in the enhancer region is in an open configuration and that the transcription factors governing its activity belong to the helix-loop-helix and the Jun/Fos leucine zipper families.
