Androgen-regulated and DDC-regulated genes. A) A Venn diagram analysis showing in yellow, the genes (130) with two fold induction in response to R1881 treatment in DDC overexpressing and control cells. The genes up- and down-regulated only in DDC overexpressing cells are represented in red (DDC; left) and the genes up- and down-regulated only in the control cells are represented in the green (controls; right). B) Reported here are 35 androgen-regulated genes differentially expressed at least 2-fold in DDC overexpressing cells (LNCaP-DDC) compared with the controls cells (LNCaP-CTRLs). The colors represent the ratio of gene expression levels in each cell line after R1881 treatment (red = hormone up-regulated and green = hormone down-regulated).
