Description
SETD5 gene mutations have been identified as a frequent cause of idiopathic intellectual disability. Here we show that Setd5 haploinsufficient mice present developmental defects such as abnormal brain to body weight ratio and neural crest defect associated phenotypes. Furthermore, Setd5 mutant mice show impairments in cognitive tasks, enhanced long-term potentiation, delayed ontogenetic profile of ultrasonic vocalisation and behavioural inflexibility. Behavioural issues are accompanied by abnormal expression of postsynaptic density proteins previously associated with cognition. Our data suggest that Setd5 might regulate RNA polymerase II dynamics and gene transcription during development and learning via its interaction with the Hdac3 and Paf1 complexes. Our results emphasize the decisive role of Setd5 in a biological pathway found to be disrupted in intellectual disability and autism spectrum disorder patients. Overall design: RNA-sequencing for wild type and Setd5 heterozygous knockout mice in two settings. First, in whole embryo samples (age E9.5), three biological replicates each. Second, gene expression changes due to contextual fear conditioning (CFC) was studied by comparing baseline transcription in homecage (HC) mice with transcription one hour (CFC_1h) or three hours (CFC_3h) after fear conditioning (4-5 biological replicates per time point and genotype).

Description
Administration of exogenous mesenchymal stem cells (MSCs) has been shown to improve the recovery from acute kidney injury (AKI). It has been suggested that the beneficial effect of MSCs is related to the paracrine release of factors favouring proliferation of intrinsic epithelial cells survived to injury rather than to their trans-differentiation. However the factors involved remain to be determined. In the present study we demonstrated that microvesicles (MVs) derived from human bone marrow MSCs are able to stimulate in vitro proliferation and apoptosis resistance of tubular epithelial cells (TEC). In addition, MVs were found to accelerate in vivo the morphological and functional recovery of glycerol induced AKI in SCID mice by inducing TEC proliferation. The effect of MVs on the recovery of AKI was comparable to that of human MSC treatment. In vitro we found that the CD44 and beta1-integrin-dependent incorporation of MVs in TEC was required for their biological action. However, despite their internalization, RNase-treated MVs failed to induce in vitro apoptosis resistance and TEC proliferation, and in vivo recovery from AKI, suggesting an RNA-dependent biological effect. Microarray analysis and quantitative RT-PCR of MV-RNA extract indicated that MVs were shuttling a specific subset of cellular mRNA, such as mRNA associated with the mesenchymal differentiative phenotype and with several cell functions involved in the control of transcription, proliferation, apoptosis and cell immune regulation. These results suggest that MVs derived from MSCs may activate a proliferative program in TEC survived to injury in AKI by an horizontal transfer of mRNA.

Description
This study relates to pregnancy outcome after assisted reproduction of fertility-classified cattle. The aim is to investigate how the uterine environment impacts and programs conceptus survival and development. The study found that ripple effects of dysregulated conceptus-endometrial interactions elicit post-elongation pregnancy loss in subfertile animals during the implantation period. Overall design: Heifer cows classified as high fertile (HF), subfertile (SF), or infertile (IF) were investigated. The RNA-seq analysis was performed for endometrium samples at day 17 of pregnancy. For comparison, non-pregnant cows were included in the analysis. RNA from conceptus of HF and SF pregnant animals (day 17) were also included in the RNA-seq analysis. A total of 25 endometrium samples (5 non-pregnant of each fertilty group, 5 pregnant HF, and 5 pregnant SF) and 27 conceptus samples (10 SF and 17 HF) were used in the RNA-seq analysis.

Description
We report a pilot investigation for poly-A RNAs differentially expressed during Mycobacterium tuberculosis infection. Participation in this investigation from March 2010 to July 2013 was voluntary, only subjects that were >18 years old and that informed written consent were considered eligible. The recruitment of tuberculosis (TB) patients was done at public hospitals in Rio de Janeiro, Brazil. The diagnostic criteria for active pulmonary tuberculosis was at least one AFB (acid-fast bacilli) -positive sputum sample for M. tuberculosis and/or positive sputum culture and/or compatible clinical evolution for pulmonary TB and less than 15 days of anti-TB treatment and was in accordance with those of the Brazilian Ministry of Health. Blood was collected from recent close contacts (rCt) and active tuberculosis (TB) index cases (n=6). Latent TB infection (LTBI) was accessed by both tuberculin skin test (TST, cut-off = 5mm) and in house interferon-gamma release assays (IGRA, cut-off = 100 pg/ml), therefore, 12 rCt were classified as uninfected controls and 16 with LTBI. Subsequently, the sequencing was performed following the standard protocols on Illumina HiSeq® 2500 Sequencing System (Illumina, San Diego, CA) running 100 bp paired-end reads (PE100) and generating approximately 30 million reads passing filter for each sample to produce the mRNA reads. Mining these RNAseq data, highly prominent modulation of DOCK9, EPHA4, and NPC2 mRNA expression was observed in the TB samples, indicating that they might have a role in TB pathogenesis. These differential modulations upon M. Tuberculosis infection were further validated by additional evidences in larger cohorts from different geographical areas. Overall design: We collected blood samples from the recent close contacts (rCt) at the recruitment and monitored them for 1-year. All TB participants were treatment-naïve. An infection mRNA signature was derived from whole blood RNA sequencing data by comparing TB and uninfected rCt. We selected the 3 most prominent genes, by area under the ROC curve analysis, for additional validations. Some of the LTBI participants also showed the mRNA infection profile.

Description
Cellular plasticity confers cancer cells the ability to adapt to micro-environmental changes, a fundamental requirement for tumour progression and metastasis. The epithelial to mesenchymal transition (EMT) is a transcriptional programme associated with increased cell motility and stemness. Beside EMT, the mesenchymal to amoeboid transition (MAT) has been described during tumour progression but, to date, little is known about its transcriptional control and involvement in stemness. The aim of this study is to investigate (i) the transcriptional profile associated with the MAT programme and (ii) to study whether MAT acquisition in melanoma cancer cells correlate with clonogenic potential to promote tumor growth. Our results demonstrate that MAT programme in melanoma is characterised by increased stemness and clonogenic features of cancer cells, thus sustaining tumour progression. Furthermore, these data suggest that stemness is not an exclusive feature of cells undergoing EMT, but more generally is associated with an increase in cellular plasticity of cancer cells.

Description
Magnaporthe oryzae is the causative agent of the rice blast, the most relevant rice disease worldwide. To date expression analysis on rice infected with Magnaporthe oryzae have been carried out only with the strains FR13 (leaf) and Guy 11 (root). However different strains of Magnaporthe are present in the environment leading to different rice responses at molecular level. To gain more insight on the unknown molecular mechanisms activated by different Magnaporthe strains during rice defense, a global expression analysis was performed by using the GeneChip Rice Genome Array.

Description
Powdery mildew is a very common plant disease and only few plants are immune. Host interactions have been identified and characterized for the pathosystems barley-B. graminis f. sp. tritici (Bgt) and wheat-B. graminis f. sp. hordei (Bgh), whereas no data are reported about powdery mildew and nonhost plants, such as rice. On the other hand rice nonhost resistance is widely unexploited and only few expression data are available. To characterize rice response during nonhost interaction with Bgh, a global expression analysis was performed by using the GeneChip Rice Genome Array.
