Description
Ikaros family DNA binding proteins are critical regulators of B cell development. To identify Ikaros-regulated genes in pre-B cells we performed gene expression studies at enhanced temporal resolution.

Senescence can be transmitted in a paracrine way from cells undergoing Oncogene Induced Senescence (OIS) to nave normal cells. We define this phenomenon as paracrine senescence

Description
We used IMR90 ER:RAS cells infected with an empty vector or an shRNA for ARID1B and induced senescence by addition of 4OHT. 6 days later RNA was collected for gene expression analysis. With a functional screen we previously identified ARID1B as a new regulator of cellular senescence. By performing gene expression analysis we confirmed this finding and showed that knockdown of ARID1B prevents the expression of genes induced during senescence.

Description
The RNase III enzyme dicer is essential for the processing of microRNAs (miRNAs) and small interfering RNAs (siRNAs) from double-stranded RNA precursors. miRNAs and siRNAs regulate chromatin structure, gene transcription, mRNA stability and translation in a wide range of organisms. To provide a model system to explore the role of dicer-generated RNAs in the differentiation of mammalian cells in vivo, we have generated a conditional dicer allele. Deletion of dicer at an early stage of T cell development compromised the survival of lineage cells, while the numbers of -expressing thymocytes were not affected. In developing thymocytes, dicer was not required for the maintenance of transcriptional silencing at pericentromeric satellite sequences (constitutive heterochromatin), the maintenance of cytosine DNA methylation and X chromosome inactivation in female cells (facultative heterochromatin) and the stable shutdown of a developmentally regulated gene (developmentally regulated gene silencing). Most remarkably, given that one-third of mammalian mRNAs are putative miRNA targets, dicer appears to be dispensable for CD4/8 lineage commitment, a process where epigenetic regulation of lineage choice has been well documented. Thus, although dicer appears critical for the development of the early embryo, it may have limited impact on the implementation of lineage-specific gene expression programs.
