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
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.

RNA seq analysis of laser capture microdissected luminal and glandular epithelium from ewes on day of pregnancy 10, 12, 14, 16 and 20. As well as RNA seq of whole conceptuses, and trophectoderm tissue from day 12, 14, 16 and 20 of pregnancy. Determination of gene expression changes in the uterine epithelium and conceptus during early pregnancy helps to improve our understanding of early pregnancy events and provides a basis of new strategies to improve fertility and reproductive efficiency in ruminants. Overall design: RNA seq analysis of 4 samples of each tissue type (luminal epithelium (LE), glandular epithelium (GE) and conceptus) for 4 animals. Pre-sequencing amplification of LE, GE and day 12 conceptus samples.

Description
This experiment was designed to look for in vitro IL-3 gene signature in donor blood at two different time points (6 and 24 hours). RNA from lysed whole blood cells was used for the sequencing. Overall design: Lysed whole blood from seven healthy donors was stimulated with recombinant human IL-3 for 6 hours, or 24 hours, prior to RNA extraction for next-generation sequencing on the Illumina HiSeq platform. Unstimulated samples were included as controls.

Description
Sustained spermatogenesis in adult males and recovery of fertility following germ cell depletion are dependent on undifferentiated spermatogonia with self-renewal potential. We have previously demonstrated a critical cell-autonomous role for Gilz in spermatogonial stem cell maintainance and spermatogenesis. To identify genes regulated by Gilz in the male germline, we have isolated undifferentiated spermatogonial cells from tamoxifen treated Gilzflox/flox (Control) and Gilzflox/flox UBC-CreER (TAM-KO) mice that will allow identification of genes mis-expressed upon loss of GILZ. Overall design: 4 independent sets of Gilzflox/flox (Control) and Gilzflox/flox UBC-CreER (TAM-KO) undifferentiated spermatogonia were isolated by flow sorting from adult mouse testes 7 days after treatment with tamoxifen.

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.

Description
Human Natural Killer (NK) cells comprise two main subsets, CD56bright and CD56dim cells, that differ in function, phenotype and tissue localization. To further dissect the heterogeneity of CD56dim cells, we have performed transcriptome analysis and functional ex vivo characterization of human NK cell subsets according to the expression of markers related to differentiation, migration or competence. Here, we show for the first time that the ability to respond to cytokines or to activating receptors is mutually exclusive in almost all NK cells with the exception of CD56dim CD62L+ cells. Indeed, only these cells combine the ability to produce interferon (IFN)-gamma after cytokines and proliferate in vivo during viral infection with the capacity to kill and produce cytokines upon engagement of activating receptors. Therefore, CD56dim CD62L+ cells represent a unique subset of polyfunctional NK cells. Ex vivo analysis of their function, phenotype, telomere length, frequencies during ageing as well as transfer experiments of NK cell subsets into immunodeficient mice suggest that CD56dim CD62L+ cells represent an intermediate stage of NK cell maturation, which after restimulation can accomplish multiple tasks and further develop into terminally differentiated effectors.

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.
