Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
The availability of pluripotent stem cells offers the possibility of using such cells to model hepatic disease and development. With this in mind, we previously established a protocol that facilitates the differentiation of both human embryonic stem cells and induced pluritpotent cells into cells with hepatocyte characteristics. The use of highly defined culture conditions and the avoidance of feeder cells or embryoid bodies allowed synchronous and reproducible differentiation to occur. The differentiation toward a hepatocytelike fate appeared to recapitulate many of the stages normally associated with the formation of hepatocytes in vivo. In the current study we addressed the feasibility of using human pluripotent stem cells to probe the molecular mechanisms underlying human hepatocyte differentiation. We demonstrate i) that human ES cells express a number of mRNAs that characterize each stage in the differentiation process, ii) that gene expression can be efficiently depleted throughout the differentiation time course using shRNAs expressed from lentiviruses, and iii) that the nuclear hormone receptor HNF4a is essential for specification of human hepatic progenitor cells by establishing expression of the network of transcription factors that control hepatocyte cell fate.

Description
Reprogrammed somatic cells offer a valuable source of pluripotent cells that have the potential to differentiate into many cells types and provide a new tool for regenerative medicine. In the present study we differentiated induced pluripotent stem cells (iPS cells) into hepatic cells. We first showed that mouse iPS cells could from a complete liver in mouse embryo (E14.5) including hepatocytes, endothelial cells, sinusoidal cells and resident macrophages. We then designed a highly efficient hepatocyte differentiation protocol using defined factors on human embryonic stem cells (ES cells). This protocol was found to generate more than 80% albumin expressing cells that show hepatic functions and express most of liver genes as shown by microarray analyses. Similar results were obtained when human iPS cells were induced to differentiate following the same procedure.

Description
Activation-induced cytidine deaminase (AID) is essential for the generation of antibody memory but also targets oncogenes among others. We investigated the transcriptional regulation of the AID gene, Aicda, in the class switchinducible CH12F3-2 cells, and found that the Aicda regulation involves derepression by several layers of positive regulatory elements in addition to the 5 promoter region. The 5 upstream region contains functional motifs for the response to signaling by cytokines, CD40-ligand, or stimuli that activate NF-B. The first intron contains functional binding elements for the ubiquitous silencers c-Myb and E2f and for B cellspecific activator Pax5 and E-box-binding proteins.
Publication Title
B cell-specific and stimulation-responsive enhancers derepress Aicda by overcoming the effects of silencers.

Description
The differences of clinical characteristics in complex seizures induced by influenza A(H1N1)pdm09 and rotavirus gastroenteritis are well known, but the pathogenic mechanisms remain unclear. We analyzed the gene expression profiles in the peripheral whole blood cells isolated from pediatric patients using an Affymetrix oligonucleotide microarray.
