Description
Transcription termination and mRNA export from the nucleus are closely regulated and coordinated processes. Nuclear export factors are recruited to actively transcribed genes through their interactions with protein complexes associated with transcription and co-transcriptional pre-mRNA processing. We determine a new role for the kinase WNK1 in the cross-talk of transcription termination and mRNA export. WNK1 was previously attributed a cytoplasmic role as a regulator of ion transport. However, we now show a nuclear function for this kinase where it is required for efficient mRNA export along with the transcription termination factor PCF11. Finally, we identify the phosphorylation of the CID domain of PCF11 as an important step for the release of the mRNA from the transcription locus, thus allowing efficient mRNA export to the cytoplasm. Overall design: RNA from cytoplasmic and nuclear extracts of HeLa cells was obtained, upon depletion of WNK1 kinase or from control cells. Upon pA selection, libraries were generated and sequenced. A duplicate experiment was performed for each sample.

Description
Purpose: The goals of this study were to determine whether the spliceosome interacts with non-intronic mRNAs Methods: RNAseq was performed on RNA that immunoprecipitated with the yeast SMD1 protein. Tandem-affinity-purified RNAs were extracted and RNAseq libraries were generated using the EpiCentre ScriptSeq kit (v1). We also performed RNAseq experiments on rRNA depleted total RNA extracted from an exosome mutant (rrp6?), a temperature-sensitive splicing mutant (prp40-1) and a parental strain (BY4741). The rRNA was depleted using the Invitrogen RiboMinus kit, according to manufactureres procedures. The depleted RNA was subsequently treated with Turbo DNAse I (Ambion) and RNAseq libraries were generated using the EpiCentre ScriptSeq kit (v1). Results: The SM RNAseq data identified a number of non-intronic mRNAs that appeard to be bound by the spliceosome. Among these was the BDF2 mRNA, which enocdes for a bromo-domain protein. BDF2 was highly enriched in both SM-IP datasets and was therefore analyzed in more detail. To determine if other non-intronic mRNAs could be regulated by the spliceosome, we analysed the transcriptome in the rrp6?, the prp40-1 and a parental strain. Bioinformatic analysis of these data sets revealed that roughly 1% of the non-intronic mRNAs in yeast could be targeted by the spliceosome. TopHat revealed cannonical splice junctions in roughly 30 non-intronic mRNAs, indicating that these messages are spliced. Conclusions: We demonstrate, for the first time, that the spliceosome can regulate expression of non-intronic mRNAs via one and/or two RNA cleavage events. We refer to this process as Spliceosome Mediated Decay (SMD). Overall design: We report RNAseq data for two SM immunoprecipitation experiments and RNAseq datasets for the parental strain (BY4741), the prp40-1 mutant, and the rrp6? strain.

Description
B220+GL7+ (GC) and B220+GL7- (non-GC) B cells were sorted from SRBC-immunized mice deficient for Hdac3 and wild type controls. RNA-sequencing revealed an upregulation of critical regulators of B cell differentiation in Hdac3-deleted animals. Overall design: 10 days post-immunization with SRBCs, GC and non-GC B cells were sorted and RNA isolated by Trizol extraction for RNA-sequencing. 2 replicates were sequenced for each condition.

Description
SF-1 is a nuclear receptor transcription factor playing a key role in adrenogonadal development and in adrenocortical tumorigenesis when overexpressed. NRSF/REST is a transcriptional repressor that represses expression of neuronal genes in non-neural tissues. Some data suggest that SF-1 and NRSF/REST can functionally interact in adrenocortical cancer cells.

Description
Microglia are yolk sac-derived macrophages residing in the parenchyma of brain and spinal cord, where they interact with neurons and other glial cells by constantly probing their surroundings with dynamic extensions. After different conditioning paradigms and bone marrow (BM) or hematopoietic stem cell (HSC) transplantation, graft-derived cells seed the brain and persistently contribute to the parenchymal brain macrophage compartment. Here we establish that graft-derived macrophages acquire, over time, microglia characteristics, including ramified morphology, longevity, radio-resistance and clonal expansion. However, even after prolonged CNS residence, transcriptomes and chromatin accessibility landscapes of engrafted, BM-derived macrophages remain distinct from yolk sac-derived host microglia. Furthermore, engrafted BM-derived cells display discrete responses to peripheral endotoxin challenge, as compared to host microglia. In human HSC transplant recipients, engrafted cells also remain distinct from host microglia, extending our finding to clinical settings. Collectively, our data emphasize the molecular and functional heterogeneity of parenchymal brain macrophages and highlight potential clinical implications for HSC gene therapies aimed to ameliorate lysosomal storage disorders, microgliopathies or general monogenic immuno-deficiencies. Overall design: overall there are 28 samples, from total of 2 experiments. in each experiment there were at least 3 biological repeats (3 individual mice). Sorting of the CD45.1 and CD45.2 populations were performed from the same animal. Animals were either injected with LPS (2.5 mg/kg) or untreated.
