(Submitter supplied) Chromatin remodelling at specific genomic loci controls lymphoid differentiation. Here, we investigated the role played in this process by Kruppel-Associated Box (KRAB)- Associated Protein 1 (KAP1), the universal cofactor of KRAB-zinc finger proteins (-ZFPs), a tetrapod-restricted family of transcriptional repressors. T cell-specific Kap1-deleted mice displayed a significant expansion of immature thymocytes, imbalances in CD4+/CD8+ cell ratios and impaired responses to TCR stimulation when compared to littermate KAP1 control mice. more...

(Submitter supplied) The modulation of chromatin status at specific genomic loci controls lymphoid differentiation.

T cell-specific Kap1 knockout mice displayed a significant expansion of immature thymocytes and imbalances in the ratios of mature T cells in the thymus and the spleen, with impaired responses to TCR stimulation. more...

(Submitter supplied) Chromatin remodeling is fundamental for B cell differentiation. Here, we explored the role in this process of KAP1, the cofactor of KRAB-ZFP transcriptional repressors. B lymphoid-specific Kap1 knockout mice displayed reduced numbers of mature B cells, lower steady-state levels of antibodies and accelerated rates of decay of neutralizing antibodies following viral immunization. Transcriptome analyses of Kap1-deleted B splenocytes revealed an upregulation of PTEN, the enzymatic counter-actor of PIK3 signaling, and of genes encoding DNA damage response factors, cell-cycle regulators and chemokine receptors. more...

(Submitter supplied) We performed a genome-scale ChIP-chip comparison of two modifications (trimethylation of lysine 9 and trimethylation of lysine 27) of histone H3 in Ntera2 testicular carcinoma cells and in three different anatomical sources of primary human fibroblasts. We found that in each of the cell types the two modifications were differentially enriched at the promoters of the two largest classes of transcription factors. more...

(Submitter supplied) The tetrapod-restricted KRAB-containing zinc finger proteins (KRAB-ZFPs) are essential early embryonic controllers of transposable elements (TEs), which they repress via their cofactor KAP1 and associated effectors through histone and DNA methylation, a process thought to result in irreversible silencing. Using a target-centered functional screen, we matched several murine TEs with their cognate KRAB-ZFP. more...

(Submitter supplied) Embryonic stem (ES) cells express pluripotency-associated genes and repress differentiation-inducible genes. The activities of these genes are coordinately reversed during differentiation. The changes in the transcriptome upon conditional KAP1 knockout in ES cells overlapped with the changes during embryoid body formation. KAP1 repressed differentiation-inducible genes and derepressed pluripotency-associated genes in ES cells. more...

(Submitter supplied) Mobile elements are important evolutionary forces that challenge genomic integrity. Long interspersed element-1 (L1, also known as LINE-1) is the only autonomous transposon still active in the human genome. It displays an unusual pattern of evolution, with at any given time a single active L1 lineage amplifying to thousands of copies before getting replaced by a new lineage likely under pressure of host restriction factors, which act notably by silencing L1 expression during early embryogenesis. more...

(Submitter supplied) The transcriptional activator MyoD serves as a master controller of myogenesis. Often in partnership with Mef2, MyoD binds to the promoters of hundreds of muscle genes in proliferating myoblasts, yet activates these targets only upon receiving cues that launch differentiation. What regulates this off/on switch of MyoD function has been incompletely understood, although known to reflect the action of chromatin modifiers. more...
