Transcript profile comparison of Zbtb20-sufficient and Zbtb20-deficient polyclonal bone marrow plasma cells

ABSTRACT: ZBTB20 is an adjuvant-specific factor for long-term antibody responses. This factor is critical for maintaining long-lived plasma cells in alum-adjuvanted antibody responses but is dispensable for TLR ligand-adjuvanted responses. To identify the functions of ZBTB20 in long-lived plasma cells, we performed microarray analysis on Zbtb20-sufficient and Zbtb20-deficient polyclonal bone marrow plasma cells under the assumption that ZBTB20 regulates relevant targets in all long-lived plasma cells, irrespective of their mode of formation. Chimeras were generated using Zbtb20-sufficient (WT) or Zbtb20-deficient (TRAP) E14.5 fetal livers. 3-4 months after reconstitution, donor bone marrow B220low/-CD138+ cells (4 replicates per genotype) were purified via FACS for microarray. In total, 8 samples, 4 for each genotype, were included in this study.

Adjuvant-specific regulation of long-term antibody responses by ZBTB20.

Wang Yinan Y Bhattacharya Deepta D

The Journal of experimental medicine 20140407 5

The duration of antibody production by long-lived plasma cells varies with the type of immunization, but the basis for these differences is unknown. We demonstrate that plasma cells formed in response to the same immunogen engage distinct survival programs depending on the adjuvant. After alum-adjuvanted immunization, antigen-specific bone marrow plasma cells deficient in the transcription factor ZBTB20 failed to accumulate over time, leading to a progressive loss of antibody production relative ...[more]

RNA-seq of Zbtb20-expressing Tregs against activated (CD62Llo) and naive (CD62Lhi) Tregs that do not express Zbtb20

Project description:The objective of this study was to determine if a subset of regulatory T cells (Tregs) expressing the transcription factor, Zbtb20, played a unique role in the function of the immune system. Genetic reporter mice were used to isolate Zbtb20-expressing Tregs as well as activated (CD62Llo) and naive (CD62Lhi) Tregs. The gene expression in these cells was determined with RNA-seq.

SUMOylation controls the neurodevelopmental function of the transcription factor Zbtb20

Project description:SUMOylation is a dynamic post-translational protein modification that primarily takes place in cell nuclei, where it plays a key role in multiple DNA-related processes. In brain cells, and particularly in neurons, mostly nuclear proteins are SUMOylated, and the SUMOylation-dependent control of a subset of neuronal transcription factors is known to regulate various aspects of nerve cell differentiation, development, and function. In an unbiased screen for endogenous SUMOylation targets in the developing mouse brain, we previously identified the transcription factor Zbtb20 as a new SUMO1 conjugate. We show here that the three key SUMO paralogues SUMO1, SUMO2, and SUMO3 can all be conjugated to Zbtb20 in vitro, and we confirm the SUMOylation of Zbtb20 in vivo. Using primary hippocampal neurons as a model system, we then demonstrate that the expression of Zbtb20 is required for proper nerve cell development and neurite growth and branching. Furthermore, we show that the SUMOylation of Zbtb20 is essential for Zbtb20 function in this context, and provide evidence indicating that SUMOylation affects the Zbtb20-dependent transcriptional profile of neurons. Taken together, our data highlight the role of SUMOylation in the regulation of neuronal transcription factors that determine nerve cell development. Specifically, our data demonstrate that key functions of the transcription factor Zbtb20 in neuronal development and neurite growth are under the obligatory control of SUMOylation.

Expression profiles in Zbtb20-overexpressed neural precursor cells

Project description:Neural precursor cells (NPCs) are multipotent cells that can generate neurons, astrocytes, and oligodendrocytes in the mammalian central nervous system. Although Zbtb20 was expressed in NPCs, its functions in neural development are not fully understood. We performed microarray analysis to examine changes in gene expression between control and Zbtb20-overexpressed NPCs.

Zbtb20-mediated repression of genes in developing CA1 pyramidal neurons

Project description:The transcriptional repressor Zbtb20 is essential for specification of hippocampal CA1 pyramidal neurons. Moreover, ectopic expression of Zbtb20 is sufficient to transform subicular and retrosplenial areas of D6/Zbtb20S mice to CA1. We used microarrays to identify genes that are repressed by Zbtb20 in developing CA1 pyramidal neurons in the CA1-transformed cortex of D6/Zbtb20S mice. For RNA extraction and hybridization on Affymetrix microarrays, we isolated the CA1-transformed subiculum and retrosplenial cortex from postnatal day 1 D6/Zbtb20S mice, as well as corresponding areas from their wildtype littermates. Total RNA was extracted using the RNeasy Lipid Tissue Mini Kit (Qiagen). Each RNA sample represents a pool of RNA obtained from dissected tissues of seven animals.

Genome-wide profiling of histone H3 lysine 27 and lysine 4 trimethylation in multiple myeloma reveals the importance of Polycomb gene targeting and highlights EZH2 as a potential therapeutic target [Seq]

Project description:Multiple myeloma (MM) is a hematopoietic malignancy characterised by the accumulation of neoplastic post-germinal centre, isotype-switched, long-lived plasma cell within the bone marrow. In genetic and clinical terms MM is highly heterogeneous and remains fatal. Here we present the first epigenomic map of MM derived from freshly isolated bone marrow plasma cells from four patients. Using ChIP- and RNA-sequencing we define a set of silent H3K27me3 targets, active genes bearing H3K4me3, and bivalent genes. Examination of 2 different histone modifications in four Multiple myeloma patients and two normal plasma cells samples. A single patient RNA-seq sample was also examined.

Hypermethylation in the ZBTB20 gene is associated with major depressive disorder

Project description:Genome-wide MeDIP-Sequencing was carried out on a total of 50 monozygotic twin pairs from the UK and Australia that are discordant for depression. We show that major depressive disorder is associated with significant hypermethylation within the coding region of ZBTB20, and is replicated in an independent cohort of 356 unrelated case-control individuals. The twins with major depressive disorder also show increased global variation in methylation in comparison with their unaffected co-twins. ZBTB20 plays an essential role in the specification of the Cornu Ammonis-1 field identity in the developing hippocampus, a region previously implicated in the development of major depressive disorder.
