2019 Brecht et al. RAG1 vAbl BioID LC-MS/MS

Project description:To identify mechanisms that regulate V(D)J recombination, we used proximity-dependent biotin identification to analyze the interactomes of full length and truncated forms of RAG1 in pre-B cells. This revealed an association of RAG1 with numerous nucleolar proteins in a manner dependent on amino acids 216-383 and allowed identification of a motif required for nucleolar localization. Experiments in transformed pre-B cell lines and cultured primary pre-B cells reveal a strong correlation between disruption of nucleoli, reduced association of RAG1 with a nucleolar marker, and increases in V(D)J recombination activity. Mutation of the RAG1 nucleolar localization motif boosts recombination while removal of the first 215 amino acids of RAG1, which are required for efficient egress from nucleoli, reduces recombination activity. Our findings indicate that nucleolar sequestration of RAG1 is a negative regulatory mechanism in V(D)J recombination and identify regions of the RAG1 N-terminal region that control nucleolar association and egress.

Effect of Rag1 mutation on kidney immune response

Project description:We used Rag1 mutant fish vs Wild type fish to analyze the kidney transcriptomic modulation and determine how the mutation affects the general gene transcription (without stimuli) in fish, but also the immune response against Poly I:C.

RAG1 targeting in the genome is dominated by chromatin interactions mediated by the non-core regions of RAG1 and RAG2

Project description:The RAG1/RAG2 endonuclease initiates V(D)J recombination at antigen receptor loci but also binds to thousands of places outside of these loci. RAG2 localizes directly to lysine 4 trimethylated histone 3 (H3K4me3) through a PHD finger. The relative contribution of RAG2-dependent and RAG1-intrinsic mechanisms in determining RAG1 binding patterns is not known. Through analysis of deep RAG1 ChIP-seq data, we provide a quantitative description of the forces underlying genome-wide targeting of RAG1. Surprisingly, sequence-specific DNA binding contributes minimally to RAG1 targeting outside of antigen receptor loci. Instead, RAG1 binding is driven by two distinct modes of interaction with chromatin: the first is driven by H3K4me3, promoter-focused, and dependent on the RAG2 PHD, and the second is defined by H3K27Ac, enhancer-focused, and dependent on "non-core" portions of RAG1. Based on this and additional chromatin and genomic features, we formulated a predictive model of RAG1 targeting to the genome. RAG1 binding sites predicted by our model correlate well with observed patterns of RAG1-mediated breaks in human pro-B acute lymphoblastic leukemia. Overall, this study provides an integrative model for RAG1 genome-wide binding and off-target activity, and reveals a novel role for the RAG1 non-core region in RAG1 targeting.

Real-time quantitative PCR analysis of Rag1-/- knockout and Rag1-/- Tbx21-/- double knockout mouse liver in a diet- and ischemia-reperfusion injury (IRI)-specific manner.

Project description:Differential gene expression of mouse cytokines and chemokines in Rag1 knockout (Rag1-/- or Rag1-KO) and Rag1-/- Tbx21-/- double knockout (Rag1-Tbet-DKO) was tested in fatty liver ischemic-reperfusion injury (IRI). C57BL/6 mice harboring Rag1-/- or Rag1-/- Tbx21-/- deletions were fed with a normal chow diet (ND, 4.09 kcal/gram,13.4% kJ/fat) or a high-fat diet (HFD, 5.10 kcal/gram, 60% kJ/fat). To induce liver ischemic-reperfusion injury in mice, an atraumatic micro clip was placed across the hepatic hilus, which interrupted the blood supply to the left and median lobes of the liver for 45-minutes of partial warm ischemia time. After 24 hours of liver IRI, the affected left lobe of the liver was harvested and stored in Allprotect Tissue Reagent (Qiagen). We used Qiagen RT² Profiler™ PCR Array for mouse cytokines & chemokines to distinguish immunologically related and diet-specific gene signatures specific to liver IRI in Rag1-KO and Rag1-Tbet-DKO mice.

Single-cell omics sequencing of kidney marrow cells from heterozygous gata2b mutated and wild type zebrafish

Project description:The transcription factor GATA2 plays a major role in the generation and maintenance of the hematopoietic system. In humans, heterozygous germline mutations in GATA2 often lead to a loss of function of one allele, causing GATA2 haploinsufficiency. In mice, Gata2 has an essential regulatory function in hematopoietic stem cell (HSC) generation and maintenance. However, whereas Gata2-null mice are lethal at embryonic day (E) 10.53, Gata2 heterozygous (Gata2+/-) mice survive to adulthood with normal blood values. However, mouse models thus emerged as a useful source to identify the function of GATA2 in HSC generation and fitness, they leave the mechanisms causing the different aspects of GATA2 deficiency syndrome largely undiscovered. Zebrafish have the advantage of having two GATA2 orthologues; Gata2a and Gata2b. Gata2a is expressed predominantly in the vasculature and is required for programming of the hemogenic endothelium. Gata2b is expressed in hematopoietic stem/progenitor cells (HSPCs) and homozygous deletion (gata2b-/-) redirects HSPCs differentiation bias, thus mimicking one of the GATA2 haploinsufficiency phenotypes found in patients. But patients carry heterozygous rather than homozygous GATA2 mutations, we specifically focused on how heterozygous Gata2b mutations could be mechanistically linked to erythro-myelodysplasia, a major clinical hallmark of GATA2 patients. To investigate the mechanisms of heterozygous GATA2 mutation caused GATA2 deficiency syndrome, we created a heterozygous gata2b mutation zebrafish model and sorted the entire progenitor and HSPC population including the lymphoid population from kidney marrow (KM) of WT and mutated zebrafish based on the scatter profile of flow cytometry for single-cell RNA (scRNA) sequencing.
