TranscriptomicsPF4-Cre mediated deletion of SRF in murine megakaryocytes.
Srf is a MADS-box transcription factor that is critical for muscle differentiation. Its function in hematopoiesis has not yet been revealed. Mkl1, a cofactor of Srf, is part of the t(1;22) translocation in acute megakaryoblastic leukemia, and plays a critical role in megakaryopoiesis. In order to te...

GenomicsIdentification of Biologically Relevant Enhancers in Human Erythroid Cells [ChIP-Seq]
Identification of cell-type specific enhancers is important for understanding the regulation of programs controlling cellular development and differentiation. Enhancers are typically marked by the co-transcriptional activator protein p300 or by groups of cell-expressed transcription factors. We hypo...

GenomicsGlobal Transcriptome Analysis and Enhancer Landscape of Human Primary T Follicular Helper and T Effector Lymphocytes (ChIP-Seq)
T follicular helper (Tfh) cells are a subset of CD4+ T helper (Th) cells that migrate into germinal centers and promote B cell maturation into memory B and plasma cells. Tfh cells are necessary for promotion of protective humoral immunity following pathogen challenge, but when aberrantly regulated, ...

TranscriptomicsPatterns of histone H3 Lysine 27 monomethylation and erythroid cell-type specific gene expression [expression]
ERYTHROID CELL-TYPE SPECIFIC GENE EXPRESSION Post-translational histone modifications, acting alone or in a context-dependent manner, influence numerous cellular processes via their regulation of gene expression. Monomethylation of histone H3 lysine 27 (K27me1) is a poorly understood histone modific...

TranscriptomicsRole of NFBD1 in global gene expression
NFBD1 (nuclear factor with BRCT domains 1), also known as MDC1 (mediator of DNA damage signaling 1), is a protein involved in the ATM signaling pathway in response to DNA damage. In addition to a role in signaling, NFBD1 possesses transactivation activity, suggesting that it may influence transcrip...

TranscriptomicsEvaluation of the amplicons for SNP typing (allele bias) and locus bias using Illumina 550-Duo BeadChip
Highly specific amplification of complex DNA pools without bias or template-independent products (TIPs) remains a challenge. We have developed a procedure using phi29 DNA polymerase and trehalose and optimized control of amplification to create micrograms of specific amplicons without TIPs from down...

GenomicsCTCF and CohesinSA-1 Mark Active Promoters and Boundaries of Repressive Chromatin Domains in Primary Human Erythroid Cells [ChIP-Seq]
CTCF and cohesinSA-1 are regulatory proteins involved in a number of critical cellular processes including transcription, maintenance of chromatin domain architecture, and insulator function. To assess changes in the CTCF and cohesinSA-1 interactomes during erythropoiesis, chromatin immunoprecipitat...
