Exposure to mites sensitizes intestinal stem cell maintenance, splenic marginal zone B cell homeostasis, and heart development to Notch dosage and cooperativity [RNA-seq]

Project description:Cooperative DNA binding is a key feature of transcriptional regulation. Here we examined the role of cooperativity in Notch signaling by CRISPR-mediated engineering of mice in which neither Notch1 nor Notch2 can homo- or heterodimerize, essential for cooperative binding to sequence paired sites (SPS) located near many Notch-regulated genes. While most known Notch-dependent phenotypes were unaffected in Notch1/2 dimer-deficient mice, a subset of tissues proved highly sensitive to loss of cooperativity. These phenotypes include heart development, compromising viability in combination with low gene dose, and the gut, developing ulcerative colitis in response to 1% DSS. The most striking phenotypes – gender imbalance and splenic marginal zone B cell lymphoma – emerged in combination with gene dose reduction or when challenged by chronic fur mite infestation. This study highlights the role of the environment in malignancy and colitis, and is consistent with Notch-dependent anti-parasite immune responses being compromised in the dimer deficient animals.

Human splenic marginal zone precursors (MZP) differentiation into marginal zone B cells (MZB)through a Notch2 signalling pathway

Project description:RNA microarray profiling analysis was performed on different ex-vivo human splenic B cell subsets (M-^SNaM-oveM-^T, marginal zone precursors or M-^SMZPM-^T, marginal zone B cells orM-^T MZBM-^T, M-^SMTG+CD45+M-^T cells) and on M-^Sp27M-^T cells, corresponding to the fraction of MZP cells that differentiated into CD27-expressing cells after culture on OP9-hDLL1 cells cultured with OP9-hDLL1 cells that differentiated into CD27-expressing cells

Molecular characterization of Nodal marginal zone lymphoma [Gene Expression]

Project description:Nodal marginal zone lymphoma (NMZL) is a small B cell neoplasm whose molecular pathogenesis is still essentially unknown and whose differentiation from other small B cell lymphomas is hampered by the lack of specific markers. We have analyzed gene expression, miRNA profile and copy number data from 15 NMZL cases. For comparison, 16 follicular lymphomas, 9 extranodal marginal zone lymphomas, 8 reactive lymph nodes and B-cell subtypes were included. The results were validated by qRT-PCR in an independent series including 61 paraffin-embedded NMZLs. NMZL signature showed an enriched expression of gene sets identifying interleukins, integrins, CD40, PI3K, NF-kB and TGF-Beta; and included genes expressed by normal marginal zone cells and memory B cells. The most highly overexpressed genes were SYK, TACI, CD74, CD82 and CDC42EP5. Genes linked to G2/M and germinal center were downregulated. Comparison of the gene expression profiles of NMZL and FL showed enriched expression of CHIT1, TGFB1 and TACI in NMZL, and BCL6, LMO2 and CD10 in FL. NMZL displayed increased expression of miR-221, miR-223 and let-7f, while FL strongly expressed miR-494. Our study identifies new candidate diagnostic molecules for NMZL and reveals survival pathways activated in NMZL. We have analyzed gene expression, miRNA profile and copy number data from 15 NMZL cases. For comparison, 16 follicular lymphomas, 9 extranodal marginal zone lymphomas, 8 reactive lymph nodes and B-cell subtypes were included.
