Expression data from knockdown of ZXDC1/2 in PMA-treated U937

ABSTRACT: ZXDC1 augments the expression of various markers of monocyte/macrophage differentiation when over-expressed in the U937 cell line treated with the phorbol ester PMA. Likewise, knockdown of ZXDC1 restricts the induced expression of these markers. We sought to identify specfic gene targets of ZXDC1 during the process of monocyte/macrophage differentiation in U937 by performing gene expression profiling in cells exhibiting reduced expression of ZXDC1 compared to controls. We used microarray to identify genes regulated by ZXDC during PMA-induced differentiation of U937 monoblasts towards a monocyte/macrophage phenotype

Project description:Human histomonocytic U937 cells exhibit macrophage-like properties after phorbol ester stimulation. Accumulating evidence demonstrated that remarkable number of transcripts changed in their amount at total RNA levels. However, post-transcriptional regulation has not been fully elucidated in this model. Thus, we compared expression profiles between polysomal and cytoplasmic RNAs before and after phorbol 12-myristate 13-acetate stimulation (48h, 32nM).
