Project description:To understand the role of LSD1 in B cell differentiation, mice with B cell conditional deletion of LSD1 were intravenously inoculated with LPS. After 3 days, B220+GL7-CD138- naïve B cells and CD138+ plasmablasts were FACS-sorted from the spleens and RNA-seq was performed to identify LSD1-target regulated chromatin.

LSD1 regulates splenic B cell chromatin accessibility

Project description:To understand the role of LSD1 in splenic B cell development, spleens from mice with B cell conditional deletion of LSD1 were harvested, B220+CD93–GL7–CD23–CD21hiCD1d+ marginal zone B cells and B220+CD93–GL7–CD23+CD21midCD1d– follicular B cells were FACS-sorted, and ATAC-seq was performed to identify LSD1-target regulated chromatin.

LSD1 regulates the plasmablast transcriptome

Project description:To understand the role of LSD1 in marginal zone B cell development, CD93+ transitional B cells were enriched from the spleens of mice with B cell conditional deletion of LSD1, the cells were cultured for 3 days in the presence of OP9-DL1 cells and BAFF, and day 0 B220+CD93+ transitional B cells and day 3 B220+CD21+CD1d+ ex vivo-derived marginal zone B cells were FACS-sorted and RNA-seq was performed to identify LSD1-target regulated genes.

SUMOylation regulates chromatin protein network and accessibility at glucocorticoid receptor-binding sites

Project description:Glucocorticoid receptor (GR) is an essential transcription factor (TF), controlling metabolism, development and immune responses. SUMOylation regulates chromatin occupancy and target gene expression of GR in a locus-selective manner, but the mechanism of regulation has remained elusive. Here, we show using selective isolation of chromatin-associated proteins that the protein network around chromatin-bound GR is affected by SUMOylation, with several nuclear receptor coregulators and chromatin modifiers being more avidly associated with SUMOylation-deficient than SUMOylation competent GR. This difference is reflected in our chromatin accessibility and gene expression data, showing that the SUMOylation-deficient GR is more potent in opening chromatin at glucocorticoid-regulated enhancers and inducing expression of their target loci. Our results thus show that SUMOylation determines GR specificity by regulating the chromatin protein network and accessibility at GR-driven enhancers. We speculate that a similar mechanism is utilized by many other SUMOylated TFs.
