(Submitter supplied) CD4+ and CD8+ double-positive (DP) thymocytes are at a critical stage during the T cell development in thymus. DP cells rearrange the T cell receptor gene Tcra to generate T cell receptors with TCR. Then DP cells differentiate into CD4 or CD8 single-positive (SP) thymocytes, Regulatory T cells, or invariant nature kill T cells (iNKT) according to the TCR signal. Chromatin organizer SATB1 is highly expressed in DP cells and plays an essential role in regulating Tcra rearrangement and differentiation of DP cells. more...

(Submitter supplied) T cell development proceeds in a series of developmental stages, which is precisely orchestrated by multiple signaling and molecular networks. Here we found a zinc finger protein Zfp335 intrinsically controls DN to DP transition, as T cell-specific deficiency in Zfp335 leads to a substantial accumulation of DN3 along with reduction of DP, CD4+ and CD8+ thymocytes. This developmental blockade at DN stage results from the impaired intracellular TCRβ expression as well as increased susceptibility to apoptosis in thymocytes. more...

(Submitter supplied) Background: There is a growing interest in the role of chromatin in acquiring and maintaining cell identity. Despite the ever growing availability of genome-wide gene expression data, understanding how transcription programs are established and regulated to define cell identity remains a puzzle. An important mechanism of gene regulation is the binding of transcription factors to specific DNA sequence motifs across the genome. more...

(Submitter supplied) During hematopoiesis, multipotential progenitors differentiate into all the types of cells found in blood by the action of complex gene regulatory networks (GRNs) comprising transcription factor (TF) genes that regulate each other’s expression. The gene regulatory logic—by which we mean the identities of the TF regulators, where they bind, whether they activate or repress, and how they interact with each other—remains unknown for most hematopoietic genes. more...

(Submitter supplied) Establishment of spatial coordinates during early Drosophila embryogenesis relies on differential activity of axis patterning enhancers. Concentration gradients along the embryonic axes of activator and repressor transcription factors (TFs) provide positional information to each enhancer, which in turn promotes transcription of a target gene in a specific spatial pattern. In order to receive the TF input, an enhancer must be accessible. more...

(Submitter supplied) Spatiotemporal gene regulation during embryonic development is driven by cis-regulatory DNA sequences called enhancers. Enhancers are activated through a combination of transcription factors (TFs) that bind to short sequence motifs within these sequences, but the order of events by which TFs read out motifs is not clear. Some TFs can only bind chromatin that is already accessible, while other TFs called pioneers can open chromatin themselves. more...

(Submitter supplied) Enhancers and silencers often depend on the same transcription factors (TFs) and are imperfectly distinguished from each other by genomic assays of TF binding or chromatin state. To identify sequence features that define enhancers and silencers, we assayed massively parallel reporter libraries of genomic sequences targeted by the photoreceptor TF CRX and found instances of enhancer, silencer, or no activity. more...

(Submitter supplied) One goal of human genetics is to understand how the information for precise and dynamic gene expression programs is encoded in the genome. The interactions of transcription factors (TFs) with DNA regulatory elements clearly play an important role in determining gene expression outputs, yet the regulatory logic underlying functional transcription factor binding is poorly understood. Many studies have focused on characterizing the genomic locations of TF binding, yet it is unclear to what extent TF binding at any specific locus has functional consequences with respect to gene expression output. more...

(Submitter supplied) We performed ChIP-Seq for Ets1 and histone modifications in P5424 thymic cells, without and with Ets1 knockdown via shRNA. Overall, we find that loss of Ets1 results in specific, higher occupancy of H3K4me1-marked nucleosomes at the Ets1 binding site, but not H3K4me3 nucleosomes. We verified the specificity of this mechanism as Ets1-dependent by also computing H3K4me1 and 3 nucleosome occupancy in hypersensitive, Ets1-depleted sites. more...

(Submitter supplied) We performed microarray analysis of gene expression in WT and Ets1-/- CD4+ CD8+ DP thymocytes. Overall, we find that Ets1-/- thymocytes display gene expression signatures closer to previous stages of thymocyte development (e.g. DN3-4) than WT DP cells, suggesting that while these cells do become DP thymocytes in the absence of Ets1, that the latter is required for the upregulation of later T-cell genes and that its presence is required for the downregulation of genes corresponding to earlier and alternative stages of development.
