Description
As recently reported by our group, we performed miRNA and gene expression profiling of CD34+ hematopoietic stem/progenitor cells (HSPCs) isolated from 42 PMF patient samples compared with 31 healthy controls. Integrative analysis of these profiles by means of Ingenuity Pathway Analysis (IPA) allowed the identification of several aberrantly regulated miRNA-mRNA target pairs organized in interaction networks. In particular, our results highlighted the up-regulation of miR-494-3p in CD34+ cells from PMF patients (Norfo R et al, Blood, 2014). Interestingly, among the most upregulated miRNAs, miR-494-3p emerges as being associated to the highest number of downregulated target mRNAs. In order to understand the biological role of miR-494-3p during the hematopoietic commitment and differentiation, we overexpressed this miRNA in cord blood (CB) derived-CD34+ cells. Cells were electroporated with either miR-494-3p miRNA mimic (mimic miR-494) or a negative control mimic (mimic Neg CTR). qRT-PCR confirmed miR-494-3p overexpression 24h and 4 days after transfection (RQ SEM, 512.60 137.37, p<.01, and 20.63 3.03, p<.01, respectively).

Description
Human naïve pluripotent stem cells (PSC) share features with pre-implantation epiblast. They thus provide an unmatched opportunity for characterising the developmental programme of pluripotency in Homo sapiens. Here we confirm that naïve PSC do not respond directly to germ layer induction, but must first acquire competence. Capacitation for multi-lineage differentiation occurs without exogenous growth factor stimulation and is facilitated by inhibition of Wnt signalling. Whole transcriptome profiling during this formative transition highlights dynamic changes in gene expression, affecting many cellular properties, including metabolism and epithelialisation. Notably, naïve pluripotency factors are exchanged for post-implantation factors, but competent cells remain devoid of lineage primed transcription. The gradual pace of transition for human naïve PSC is consistent with the timespan of primate development from blastocyst to gastrulation. Transcriptome trajectory during in vitro capacitation of human naïve cells tracks the progression of epiblast during embryogenesis in Macaca fascicularis, but shows greater divergence from mouse development. Thus the formative transition of naïve PSC in a simple culture system may recapitulate essential and specific features of pluripotency dynamics during an inaccessible period of human embryogenesis. Overall design: 2 lines of human naïve pluripotent stem cells (embryo-derived HNES1 and chemically reset cR-H9-EOS) were cultured in N2B27 and 2uM XAV939 for 10 days. After that the cells were split into two conditions: N2B27 + 2uM XAV939 + 3ng/ml Activin A + 10ng/ml FGF2 (XAF), or E8 medium, for extended maintenance. The experiment was performed in biological triplicates for each cell line. RNAseq was performed with the cells on day 0, 1, 2, 3, 7, 10, when the cells were cultured in XAV939; and one time point after transfer to maintenance conditions, at not less than 22 days of culture from the start of the experiment. Conventional hES cell line H9-EOS, which was a parental line for the chemically reset cR-H9-EOS was used as a control (in biological triplicate).

Description
Airway remodelling in chronic obstructive pulmonary disease (COPD) originates, in part, from smoking-induced changes in airway basal stem/progenitor cells (BCs). Based on the knowledge that bone morphogenetic protein 4 (BMP4) influences epithelial progenitor function in the developing and adult mouse lung, we hypothesised that BMP4 signalling may regulate the biology of adult human airway BCs relevant to COPD.

Description
Although liganded nuclear receptors have been established to regulate RNA polymerase II (Pol II)-dependent transcription units, their role in regulating Pol III-transcribed DNA repeats remains largely unknown. Here we report that ~2-3% of the ~100,000-200,000 total human DR2 Alu repeats located in proximity to activated Pol II transcription units are activated by the retinoic acid receptor (RAR) in human embryonic stem cells to generate Pol III-dependent RNAs. These transcripts are processed, initially in a DICER-dependent fashion, into small RNAs (~28-65 nt) referred to as repeat-induced RNAs that cause the degradation of a subset of crucial stem-cell mRNAs, including Nanog mRNA, which modulate exit from the proliferative stem-cell state. This regulation requires AGO3-dependent accumulation of processed DR2 Alu transcripts and the subsequent recruitment of AGO3-associated decapping complexes to the target mRNA. In this way, the RAR-dependent and Pol III-dependent DR2 Alu transcriptional events in stem cells functionally complement the Pol II-dependent neuronal transcriptional program. Overall design: RNA-sequencing of polyA selected RNA molecules in NTera2/D1 cells and Global Run On (GRO) assay followed by high throughput sequencing (GRO-seq).

Description
Background: Metabolic plasticity involving shifts between mitochondrial respiration and glycolysis is emerging as a crucial component of efficient innate immune cell responses. Alveolar macrophages (AMs), the most abundant antigen-presenting cells in the lung, are dramatically increased in the lungs of patients with chronic obstructive pulmonary disease (COPD). However, COPD AMs exhibit dysfunctional responses to infection with lower phagocytic ability and impairment of mitochondrial reactive oxygen species (ROS) generation. Little is known about the mitochondrial function or respiration of these cells and whether alterations in their mitochondrial or glycolytic activities may contribute to the pathogenesis of COPD.

Description
Bone marrow stromal cells (BMSCs) were isolated from the femora and tibiae of irtTA-GBD*-TAg transgenic mice. Using cellular cloning we established skeletal progenitors with distinct differentiation properties and analysed their transcriptome. Unipotent osteogenic and adipogenic cells expressed specific transcriptional programs whereas bipotent clones combined expression of those genes and did not show a unique signature. Overall design: Expression profiling (RNA-seq) of two independent clones from different mice representing skeletal progenitors with the following characteristics: tripotent clones (Osteogenic, Adipogenic, Chondrogenic = OAC1 and OAC2); bipotent clones (Osteogenic, Adipogenic = OA1 and OA2); unipotent clones (Osteogenic = O1 and O2; Adipogenic = A1 and A2). Further, we prepared and sequenced pools of several other clones from these two mice, with the following properties: tripotent clones (Osteogenic, Adipogenic, Chondrogenic = OAC3); bipotent clones (Osteogenic, Adipogenic = OA3; Osteogenic, Chondrogenic = OC3; Adipogenic, Chondrogenic = AC3); unipotent clones (Osteogenic = O3; Adipogenic = A3).
