Microgravity as well as chronic muscle disuse are two causes of low back pain originated at least in part from paraspinal muscle deconditioning. At present no study investigated the complexity of the molecular changes in human or mouse paraspinal muscles exposed to microgravity. The aim of this study was to evaluate longissimus dorsi and tongue (as a new potential in-flight negative control) adaptation to microgravity at global gene expression level. C57BL/N6 male mice were flown aboard the BION-M1 biosatellite for 30 days (BF) or housed in a replicate flight habitat on ground (BG). . Global gene expression analysis identified 89 transcripts differentially regulated in longissimus dorsi of BF vs. BG mice (False Discovery Rrate < 0,05 and fold change < -2 and > +2), while only a small number of genes were found differentially regulated in tongue muscle ( BF vs. BG = 27 genes).

View SamplesMicrogravity exposure as well as chronic muscle disuse are two of the main causes of physiological adaptive skeletal muscle atrophy in humans and murine animals in physiological condition. The aim of this study was to investigate, at both morphological and global gene expression level, skeletal muscle adaptation to microgravity in mouse soleus and extensor digitorum longus (EDL). Adult male mice C57BL/N6 were flown aboard the BION-M1 biosatellite for 30 days on orbit (BF) or housed in a replicate flight habitat on Earth (BG) as reference flight control.

View SamplesCNS-delivery of Interleukin 4 (IL-4) - via a lentiviral-mediated gene therapy strategy - skews microglia to proliferate, inducing these cells to adopt the phenotype of slowly proliferating cells. Transcriptome analysis revealed that IL-4-treated microglia express a broad number of genes normally encoded by embryonic microglia. Overall design: RNAseq analysis of sorted microglia from mice receiving IL-4 gene therapy
Interleukin 4 modulates microglia homeostasis and attenuates the early slowly progressive phase of amyotrophic lateral sclerosis.

View SamplesWe explore the heterogeneity of mouse thoracic ganglia demonstrating the presence of an unexpected variety of cell-types and identify specialized populations of nipple- and pilo-erector muscle neurons. These neurons extend axonal projections and are born amongst other neurons during embryogenesis, but remain unspecialized until target organogenesis occurs postnatally. Target innervation and cell-type specification is coordinated by an intricate acquisition of unique combinations of growth factor receptors and the initiation of expression of concomitant ligands by the nascent erector muscles. Overall design: RNA-seq analysis of 298 single sympathetic neuronal cells from the mouse thoracic ganglion
Visceral motor neuron diversity delineates a cellular basis for nipple- and pilo-erection muscle control.

View SamplesGraft versus host disease (GVHD) is the most common complication of hematopoietic stem cell transplant (HCT). However, our understanding of the molecular pathways that cause this disease remains incomplete, leading to inadequate treatment strategies. To address this, we measured the gene expression profile of non-human primate (NHP) T cells during acute GVHD. In this study we specifically interrogated the transcriptional signatures of animals treated with FR104 monotherapy and FR104/Sirolimus combination therapy
Combined OX40L and mTOR blockade controls effector T cell activation while preserving T<sub>reg</sub> reconstitution after transplant.

View SamplesGraft versus host disease (GVHD) is the most common complication of hematopoietic stem cell transplant (HCT). However, our understanding of the molecular pathways that cause this disease remains incomplete, leading to inadequate treatment strategies. To address this, we measured the gene expression profile of non-human primate (NHP) T cells during acute GVHD. This transcriptome analysis enables an unsupervised approach to the identification of targets for disease control using a model with an immune system that closely overlaps with the human and has a high degree of cross-reactivity with human antibody-based therapeutics.

View SamplesGraft versus host disease (GVHD) is the most common complication of hematopoietic stem cell transplant (HCT). However, our understanding of the molecular pathways that cause this disease remains incomplete, leading to inadequate treatment strategies. To address this, we measured the gene expression profile of non-human primate (NHP) T cells during acute GVHD (GSE73723). Within these profiles we discovered potentially druggable targets not previously implicated in GVHD, prominently including aurora kinase A (AURKA). In this study, we performed a planned comparison of AURKA gene expression in HCT-recipients with clinical GVHD and compared it to expression in HCT-recipients without clinical GVHD.
