TranscriptomicsTranscription profiling of chicken Pax5 deficient DT40 B cell line
PAx5 is indispensible for the committment if early lymphoid progenitors to the B cell lineage as well as for the development and maintenance of B cells. To better understand the functional importance of Pax5 in the later stages of B cell development and investigate the targets of Pax5 regulation, w...

TranscriptomicsInducible PAX5 expression in a human B lymphoblastic leukemia cell line
Hypomorphic mutations of the transcription factor PAX5 occur in one third of B-progenitor acute lymphoblastic leukemias (B-ALLs). To identify PAX5-regulated genes in B-ALL, here we employ inducible expression of PAX5 in a human B-ALL cell line (REH) that harbors a loss-of-function mutation in PAX5. ...

TranscriptomicsPax5 restoration in a mouse model of B progenitor acute lymphoblastic leukemia
Hypomorphic mutations of PAX5 occur in one third of B-progenitor acute lymphoblastic leukemias (B-ALLs), however their functional consequences remain undefined. Here we employ advanced transgenic RNAi in mice to suppress endogenous Pax5 expression in the hematopoietic compartment in vivo, which co-o...

ProteomicsEssential role of the Pax5 C-terminal domain in controlling B cell commitment and development
Pax5 controls B-cell commitment, development and immunity by repressing B-lineage-inappropriate genes and activating B-cell-specific genes. In addition to the N-terminal DNA-binding paired domain, Pax5 contains a conserved octapeptide, partial homeodomain and C-terminal sequences with transactivatin...

GenomicsIGH analysis in pro-B cells with H3K4me3, H3K4me2, H3K9ac, H3K27me3, Pax5 and CTCF [ChIP-Seq]
VH-DJH recombination of the immunoglobulin heavy-chain (Igh) locus is temporally and spatially controlled during early B-cell development, and yet no regulatory elements other than the VH gene promoters have been identified throughout the entire 2.5-Mb VH gene cluster. Here we discovered novel regul...

TranscriptomicsThe transcription factor Pax5 regulates its target genes by recruiting chromatin-modifying proteins in committed B cells
Pax5 is a critical regulator of B cell commitment. Here we identified direct Pax5 target genes by streptavidin-mediated ChIP-chip analysis of pro-B cells expressing in vivo biotinylated Pax5. By binding to promoters and enhancers, Pax5 directly regulates the expression of multiple transcription fact...

TranscriptomicsChip-chip from pro-B cells with H3K4me3, H3K4me2 and H3K9ac
The transcription factor Pax5 represses B-lineage-inappropriate genes and activates B-cell-specific genes in B-lymphocytes. Here we have identified 170 novel Pax5-activated genes. Conditional mutagenesis demonstrated that the Pax5-regulated genes require continuous Pax5 activity for normal expressio...

ProteomicsA SIRT7-dependent acetylation switch regulates early B-cell differentiation and lineage commitment through PAX5
B lymphopoiesis is a key developmental event orchestrated by a complex combinatorial action of lineage-specific transcription factors. In early B cell progenitors, lineage commitment is directly mediated by the master regulator PAX5, whose deficiency is commonly associated with B cell Acute Lymphobl...
