Identification of differentially regulated genes upon shRNA-mediated knock-down of HLX in the URE leukemia cell line

To study the role of Hlx in hematopoietic differentiation and tumorigenesis, URE cells were infected with short-hairpin-containing pSIH1-H1-copGFP lentiviral vector (System Biosciences, Mountain View, CA) containing either nucleotide sequences targeting luciferase (shControl) or HLX (shHLX). After 24hrs incubation in Iscoves modified Dulbeccos medium (IMDM) containing FBS, mIL-3, mIL-6 and mSCF with lentiviral supernatants in the presence of 8ug/ml polybrene, cells were cultured in fresh medium for several days. Subsequently, GFP+ cells were sorted by FACS and RNA was prepared.
