Description
Using a mouse model overexpressing human SNCA and profiling the striatal transcriptome, we assessed gene-environment interactions to reveal perturbations in gene expression and their modulation through chronic unpredictable mild stress (CUMS) exposure. Overall design: Using a 2x2 factorial design, we cross-compared a line of transgenic mice overexpressing human SNCA with wildtype animals, and the effects of chronic unpredictable mild stress (CUMS) with standard housing conditions. Employing RNA-seq, we profiled gene expression in the striatum of 6-month-old female animals.

Description
Two pancreatic cancer cell lines with different metastatic and growth potential were compared under hypoxic conditions and under normal atmospheric oxygen pressure. The FG cell lines shows very few metastases and slow growth in mouse xenograft models. L3.6pl, derived from FG by cycles re-implantation of metastatic cells obtained after orthotopic tumor growth in nude mice, shows high motility, aggressive growth and very high metastatic potential

Description
The stromal microenvironment plays a vital role in cancer initiation and progression. We performed a comparative expression profiling of pulmonary MSC derived from NSCLC and corresponding normal lung tissue of 5 newly diagnosed patients. The analysis indicated variable expression of genes involved in DNA repair, apoptosis, proliferation or angiogenesis between NSCLC-MSC and NLT-MSC.

Description
Vascular permeability reflects changes in the function of the endothelium, its interendothelial junctions and transcellular delivery. Here, we show that common molecular mechanisms exist between VEGF and histamine in regulating vascular hyperpermeability. Crosstalk between downstream signaling of VEGF and histamine receptors are involved in calcium signaling and cell proliferation. Understanding the molecular mechanisms of vascular permeability is crucial in order to reduce vascular hyperpermeability and oedema in various pathological conditions and in VEGF therapy. Overall design: In despite of the substantial knowledge of VEGF and histamine signal transduction and their physiological responses, molecular mechanisms inducing endothelial cell permeability and proliferation have remained inconclusive. To monitor the transcriptional alteration of proteins known to regulate the endothelial permeability, next-generation RNA sequencing was used. Fold changes of several genes known to regulate calcium signaling, cell adhesion, cell proliferation, ion flux and immune response were compared between the permeabilizing agents.

Description
The 14-week experiment included three groups: 1) the Acute Cpn group, with one C. pneumoniae inoculation at the age of 9 wks; 2) the Chronic Cpn group, with three C. pneumoniae inoculations at the age of 9, 11, and 13 wks; and 3) the control group, with three SPG inoculations at the age of 9, 11, and 13 wks. The mice were sacrificed at the age of 14 wks. The 24-week experiment included four groups: 1) the recurrent A. actinomycetemcomitans infection group, with ten A. actinomycetemcomitans inoculations once a week from the age of 14 to 23 wks; 2) the chronic C. pneumoniae infection group, with three C. pneumoniae inoculations at the age of 9, 11, and 13 wks; 3) the combined chronic C. pneumoniae and recurrent A. actinomycetemcomitans infection group, with three C. pneumoniae inoculations at the age of 9, 11, and 13 wks, and ten A. actinomycetemcomitans inoculations once a week from the age of 14 to 23 wks; and 4) the control group, with three SPG inoculations at the age of 9, 11, and 13 wks, and ten 0.9% NaCl inoculations once a week from the age of 14 to 23 wks. The mice were sacrificed at the age of 24 wks.Epididymal and inguinal AT gene expression was analyzed using an Illumina Mouse WG-6 v2.0 platform.

Description
These data represents a microgenomic approach to dissect the response of the plant steroid hormone, brassinosteroid, in the provascular tissue of the arabidopsis thaliana primary roots. We used two different provascular markers, wooden leg (WOL) and corona (ATHB15) to profile the provascular response to BRs. We used a timecourse analysis with 4 different timepoint; 0.5, 1, 2 and 4 hours treated with BRs in the WOL domain. Additional trasncriptomic responses of the ATHB15 domain were analyzed after 2 hours BRs treatment.

Description
In this study, we set out to identify those molecular features of the POU transcription factor Oct4 that are responsible for inducing pluripotency in somatic cells. Oct4 is known to have a strong preference to cooperate with Sox2 on heterodimeric SoxOct elements predominantly found in enhancers of genes expressed in embryonic stem cells (ESCs). To test whether this partnership is specific to Oct4, we compared its DNA recognition and reprogramming activities to the paralogous transcription factor Oct6, which cannot induce and maintain pluripotency in mouse cells. By analyzing ChIP-Seq data and performing quantitative dimerization assays, we found that in somatic cells, instead of heterodimerzing with Sox-factors, Oct6 more potently homodimerizes on OctOct elements. We identified that a single amino acid is crucial in directing binding to the respective composite DNA element. As a consequence, just changing this one amino acid hampers Oct4 in generating induced pluripotent stem cells (iPSCs). In contrast, the reverse mutation in Oct6 did not augment its reprogramming activity. This was achieved with at least two additional exchanges. In summary, we demonstrate that cell-type specific POU factor function is determined by a limited set of residues that affect DNA and partner factor interactions. Such relatively minor changes lead to a pronounced impact on regulatory function and reprogramming activity.

Changing POU dimerization preferences converts Oct6 into a pluripotency inducer.
