Description
We previously identified multipotent stem cells within the lamina propria of the human olfactory mucosa, located in the nasal cavity. We also demonstrated that this cell type differentiates into neural cells and improves locomotor behavior after transplantation in a rat model of Parkinsons disease. Yet, next to nothing is known about their specific stemness characteristics. We therefore devised a study aiming to compare olfactory lamina propria stem cells from 4 individuals to bone marrow mesenchymal stem cells from 4 age- and gendermatched individuals. Using pangenomic microarrays and immunostaining with 34 cell surface marker antibodies, we show here that olfactory stem cells are closely related to bone marrow stem cells. However, olfactory stem cells exhibit also singular traits. By means of techniques such as proliferation assay, cDNA microarrays, RT-PCR, in vitro and in vivo differentiation, we report that, when compared to bone marrow stem cells, olfactory stem cells display i) a high proliferation rate; ii) a propensity to differentiate into osseous cells and iii) a disinclination to give rise to chondrocytes and adipocytes. Since peripheral olfactory stem cells originate from a neural crest-derived tissue and, as shown here, exhibit an increased expression of neural cellrelated genes, we propose to name them olfactory ecto-mesenchymal stem cells (OE-MSC). Further studies are now required to corroborate the therapeutic potential of OE-MSCs in animal models of bone and brain diseases.

Illumina Genome Analyzer II
Description
The study pursued dual goals: To advance mRNA-seq bioinformatics towards unbiased transcriptome capture and to demonstrate its potential for discovery in neuroscience by applying the approach to an in vivo model of neurological disease. We found that 12.4% of known genes were induced and 7% were suppressed in the dysfunctional (but anatomically intact) L4 dorsal root ganglion (DRG) 2 weeks after L5 spinal Nerve Ligation (SNL). A new algorithm for agnostic mapping of pre-mRNA splice junctions (SJ) achieved a precision of 97%. Overall design: mRNA-seq of L4 DRG 2 weeks and 2 months after L5 spinal nerve ligation. CONTROL and SNL were used to identify differential gene expression between chronic pain and standard conditions in Rattus norvegicus. CONTROL and SNL and PILOT were used to perform 'agnostic splice site discovery' in the nervous system transcriptome in Rattus norvegicus

Description
Recently a genome of Russian individual (somatic DNA from blood) was sequenced (Skryabin et al. 2009). That study was continued to find a linkage between genetic differences in parental alleles and bias in biallelic expression of genes.

Description
RNA seq analyses were performed in granulosa cells (GCs) collected from gonadotropin treated ESR2 mutant rats. Data obtained from a null mutant with Esr2 exon 3 deletion (?3) and another DNA binding domain (DBD) mutant with exon 4 deletion (?4) were compared to that of wildtype (WT) rats. The raw data were analyzed using CLC genomics workbench. High quality RNA-sequencing reads were aligned to the Rattus norvegicus genome. Differentially expressed genes in ?3 or ?4 Esr2-mutant GCs were identified based on the following criteria: FDR p-Value =0.05 and an absolute fold change of 2. Fewer differentially expressed genes were identified in ?3 compared to the ?4 mutant group. As both of the mutant groups demonstrated a common phenotype of ovulation failure, differentially expressed genes common to both in ?3 and ?4 mutant rats were emphasized and further analyzed in the companion article “ESR2 regulates granulosa cell genes essential for follicle maturation and ovulation” (Khristi et al., 2018).

Description
CtBP is a global co-repressor by serving as transcriptional factor in multiple pathways. CtBP functioned as transcriptional factor by recruiting other cofactors such as G9a, HDAC1 and PcG proteins. CtBP is found to be over enriched in several type of tumor samples. To dipict the role of CtBP in globally regulating gene expression, we applied gene microarray technology to find out what subgroups of genes are mainly affected.
