Description
Germline mutations of the SMARCB1 gene predispose to two distinct tumor syndromes: rhabdoid tumor predisposition syndrome, with malignant pediatric tumors mostly developing in brain and kidney, and familial schwannomatosis, with adulthood benign tumors involving cranial and peripheral nerves. The mechanisms by which SMARCB1 germline mutations predispose to rhabdoid tumors versus schwannomas are still unknown. Here, to understand the origin of these two types of SMARCB1-associated tumors, we generated different tissue- and developmental stage-specific conditional knockout mice carrying Smarcb1 and/or Nf2 deletion. Smarcb1 loss in early neural crest was necessary to initiate tumorigenesis in the cranial nerves and meninges with typical histological features and molecular profiles of human rhabdoid tumors. By inducing Smarcb1 loss at later developmental stage in the Schwann cell lineage, in addition to biallelic Nf2 gene inactivation, we generated the first mouse model developing schwannomas with the same underlying gene mutations found in schwannomatosis patients. Overall design: RNA-sequencing of 12 Smarcb1-deficient mouse cranial nerves and meninges tumors

Description
Summary: Spinal cord injury (SCI) is a damage to the spinal cord induced by trauma or desease resulting in a loss of mobility or feeling. SCI is characterized by a primary mechanical injury followed by a secondary injury in which several molecular events are altered in the spinal cord often resulting in loss of neuronal function.

Description
AQM shows acute muscle wasting and weakness. Key aspects of AQM include muscle atrophy and myofilament loss. Gene expression profiling, using muscle biopsies from AQM, neurogenic atrophy and normal controls, showed that both myogenic and neurogenic atrophy share induction of myofiber-specific ubiquitin/proteosome pathways while only the AQM shows a specific strong induction of transforming growth factor (TGF)-beta/MAPK pathways.

Description
The three-dimensional (3D) organization of chromosomes can influence transcription. However, the frequency and magnitude of these effects is still controversial. To determine how changes in chromosome positioning affect transcription we characterized nuclear organization and global gene expression after large-scale chromosomal rearrangements in budding yeast. We used computational modelling and single cell imaging to determine chromosome position and integrated these data with genome-wide transcriptional profiles from RNA sequencing. Chromosome displacement relative to the nuclear periphery has mild but widespread and significant effects on transcription. Our study suggests that basal transcriptional activity is sensitive to radial changes on chromosomal position, and provides support for the functional relevance of budding yeast chromosome-level 3D organization in gene expression. Overall design: We analysed 42 samples in total: wildtype (409) strain (4 replicas), mutant strain 524 (4 replicas), mutant strain 527 (4 replicas), mutant strain 1138 (4 replicas), mutant strain 1228 (4 replicas), mutant strain 1379 (4 replicas), mutant strain 1387 (4 replicas), mutant strain 1380 (4 replicas), mutant strain 1388 (4 replicas), mutant strain 1788 (3 replicas), mutant strain 1793 (3 replicas)

Description
Cellular function is strongly dependent on surrounding cells and environmental factors. Current technologies are limited in characterizing the spatial location and unique gene-programs of cells in less structured and dynamic niches. Here we developed a method (NICHE-seq) that combines photoactivatable fluorescent reporters, two-photon microscopy and single-cell RNA-seq to infer the cellular and molecular composition of niches. We applied NICHE-seq to examine the high-order assembly of immune cell networks. NICHE-seq is highly reproducible in spatial tissue reconstruction, enabling identification of rare niche-specific immune subpopulations and unique gene-programs, including natural killer cells within infected B cell follicles and distinct myeloid states in the marginal zone. This study establishes NICHE-seq as a broadly applicable method for elucidating high-order spatial organization of cell types and their molecular pathways. Overall design: Transcriptional profiling of single cells from the specific immune niches in the lymph node and spleen, generated from deep sequencing of tens of thousands of cells, sequenced in several batches on illumina Nextseq500

Description
Evidence from multiple linkage and genome-wide association studies suggest that human chromosome 2 (HSA2) contains alleles that influence blood pressure (BP). Homologous to a large segment of HSA2 is rat chromosome 9 (RNO9), to which a BP quantitative trait locus (QTL) was previously mapped. The objective of the current study was to further resolve this BP QTL. Eleven congenic strains with introgressed segments spanning <81.8kb to <1.33Mb were developed by introgressing genomic segments of RNO9 from the Dahl salt-resistant (R) rat onto the genome of the Dahl salt-sensitive (S) rat and tested for BP. The congenic strain with the shortest introgressed segment spanning <81.8kb significantly lowered BP of the hypertensive S rat by 25 mm Hg and significantly increased its mean survival by 45 days. In contrast, two other congenic strains had increased BP compared with the S. We focused on the <81.8kb congenic strain which represents the shortest genomic segment to which a BP QTL has been definitively mapped to date in any species. Sequencing of this entire region in both S and R rats detected 563 variants. The region did not contain any known or predicted rat protein coding genes. Further, a whole genome renal transcriptome analysis between S and the <81.8kb S.R congenic strain revealed alterations in several critical genes implicated in renal homeostasis. Taken together, our results provide the basis for future studies to examine the relationship between the candidate variants within the QTL region and the renal differentially expressed genes as potential causal mechanisms for BP regulation.
