Project description:During embryogenesis, the endothelial and the hematopoietic lineages first appear during gastrulation in the blood island of the yolk sac. We have previously reported that an Ets variant gene 2 (Etv2/ER71) mutant embryo lacks hematopoietic and endothelial lineages, however, the precise roles of Etv2 in yolk sac development remains unclear. We carried out a transcriptome analysis using an ES cell line that can inducibly express Etv2. Cells were induced for 12 hours at day 3 of differentiation.
Project description:To study the correlation between sequence motif appearance, transcription factor binding and aberrant hypermethylation in the cell lines, we performed ChIP-on-chip analyses (on CpG island microarrays) for the transcription factors Sp1, NRF1 and YY1 in normal peripheral blood monocytes. Keywords: ChIP-on-Chip; comparative genomic hybridization

Project description:Kashin-Beck disease (KBD) is an endemic and chronic osteochondropathy with unknown etiology. The disease mostly occurs in children between the ages of 3 and 13 in a diagonal belt-like area ranging from Northeast to Southwest China. We carried out this microarray analysis to investigate the differences in gene expression levels between KBD patients and healthy controls. Total RNA was isolated from peripheral blood mononuclear cells (PBMCs).

We carried out a transcriptome analysis using an ES cell line that can inducibly express Etv2. Cells were induced for 12 hours at day 3 of differentiation. An ES cell line (dervied from mouse of background strain 129P2/Ola) with a doxycycline inducible expression casette of Etv2 (ER71 A2Lox.cre) was differentiated in hanging drops. At 3 days of differentiation, cells were treated with doxycycline for 12 hours, and subsequently Flk1(+) cells were sorted. Experiment was done in triplicate and untreated cells were used for control.
