Gene Expression profile of Vitamin D3 treated HL60 cells shows a phenotypic but not a complete functional conversion to monocytes

Abstract

Acute Myeloid leukemia blast cells are characterized by their inability to proceed spontaneously toward terminal differentiation. To tackle this problem we have studied the changes occurring in the gene expression profile during the differentiation of HL60 cells treated with VD using the Affymetrix GeneChip technology and we have compared the molecular phenotype of VD induced cells to that of CD14+ pheripheral monocytes
