Description
Anaplastic large-cell lymphoma (ALCL) makes up approximately 15% of paediatric non-Hodgkin's lymphomas of childhood. The vast majority of them is associated with the t(2;5)(p23;q35) translocation that results in the expression of a hybrid oncogenic tyrosine kinase, NPM-ALK. In order to investigate ALCL biological characteristics we used transcriptional profiling approach. Genome-wide gene expression profiling, performed on 23 paediatric ALCL and 12 reactive lymph nodes specimens, showed two novel ALCL subgroups based on their NPM-ALK expression levels (named (ALK low and ALK high). Gene set enrichment analysis revealed, in ALK low samples, a positive enrichment of genes involved in the Interleukin signaling pathway, whereas we found increased expression of genes related to cell cycle progression and division in ALK high tumour samples, such as Aurora Kinase A (AURKA) and B (AURKB). Growth inhibition was observed upon administration of AURKA and AURKB inhibitors Alisertib and Barasertib and it was associated with perturbation of the cell cycle and induction of apoptosis. In conclusion we identified two novel ALCL subgroups, which display unique biological characteristics suggesting sensitivity to distinct targeted therapies.

Description
Phenotypic changes induced by extracellular vesicles (EVs) have been implicated in the recovery of acute kidney injury (AKI) induced by mesenchymal stromal cells (MSCs). miRNAs are potential candidates for cell reprogramming towards a pro-regenerative phenotype. The aim of the present study was to evaluate whether miRNA de-regulation inhibits the regenerative potential of MSCs and derived-EVs in a model of glycerol-induced AKI in SCID mice. For this purpose, we generated MSCs depleted of Drosha, a critical enzyme of miRNA maturation, to alter miRNA expression within MSCs and EVs. Drosha knock-down MSCs (MSC-Dsh) maintained the phenotype and differentiation capacity. They produced EVs that did not differ from those of wild type cells in quantity, surface molecule expression and internalization within renal tubular epithelial cells. However, EVs derived from MSC-Dsh (EV-Dsh) showed global down-regulation of miRNAs. Whereas, wild type MSCs and derived EVs were able to induce morphological and functional recovery in AKI, MSC-Dsh and EV-Dsh were ineffective. RNA sequencing analysis showed that genes deregulated in the kidney of AKI mice were restored by treatment with MSCs and EVs but not by MSC-Dsh and EV-Dsh. Gene Ontology analysis showed that down-regulated genes in AKI were associated with fatty acid metabolism. The up-regulated genes in AKI were involved in inflammation, ECM-receptor interaction and cell adhesion molecules. These alterations were reverted by treatment with wild type MSCs and EVs, but not by the Drosha counterparts. In conclusion, miRNA depletion in MSCs and EVs significantly reduced their intrinsic regenerative potential in AKI, suggesting a critical role of miRNAs. Overall design: RNA-seq

Description
Pulmonary sarcomatoid carcinomas (PSCs) are rare and aggressive histological types of non-small cell lung cancer (NSCLC) with a median overall survival of about 9-12 months. In detail, PSCs comprise five different histological subtypes: pleomorphic carcinoma (PLC), giant cell carcinoma (GCC), spindle cell carcinoma (SCC), carcinosarcoma (CS) and pulmonary blastoma (PB). Preoperative pathological diagnosis may fail to identify these tumors and therapeutic options are still limited. PSCs have been scarcely characterized from a molecular point of view because of their rarity, and to date no specific markers have been found for PSCs in comparison with other NSCLC types. In this study a highly sensitive amplicon based whole transcriptome quantification analysis was performed, using the Ion AmpliSeq Transcriptome Human Gene Expression Kit (Life Technologies) on a selected series of 14 PSCs (1 PB, 4 CS, 2 SCC, 2 GCC, 5 PLC) and 3 samples of normal lung parenchyma. PSCs expression data were then compared with transcriptome data of lung adenocarcinoma and squamous cell carcinoma available on The Cancer Genome Atlas database. Thirty-eight genes specifically deregulated in PSC samples were identified. Among these, IGJ and SLMAP were validated by immunohistochemistry on an independent cohort (30 PSCs, 31 lung adenocarcinoma and 31 squamous cell carcinoma cases). Furthermore, a pathway enrichment analysis, performed on differentially expressed genes, revealed that FOXO signalling and Fanconi Anemia pathways, playing a pivotal role in cancer development and progression, are enriched in PSC tumors. The description of peculiar molecular profiles besides increasing our knowledge on PSCs biology may suggest new diagnostic and therapeutic strategies. Overall design: Whole transcriptome targeted gene quantification analysis was perfomed on a selected series of 14 pulmonary sarcomatoid carcinomas (1 pulmonary blastoma, 4 carcinosarcomas, 2 spindle cell carcinomas, 2 giant cell carcinomas, 5 pleomorphic carcinomas) and 3 samples of normal lung parenchyma, using the Ion AmpliSeq Transcriptome Human Gene Expression Kit ( Life Technologies).

Description
The zebrafish heart remarkably regenerates after a severe ventricular damage followed by inflammation, fibrotic tissue deposition and removal concomitant with cardiac muscle replacement. We have investigated the role of the endocardium in this regeneration process. 3D-whole mount imaging in injured hearts revealed that GFP-labelled endocardial cells in ET33mi-60A transgenic fish become rapidly activated and highly proliferative at 3 days post cryoinjury (dpci). Endocardial cells extensively expand within the injury site and organize to form a coherent structure at 9 dpci that persists throughout the regeneration process. Upon injury, endocardial cells strongly up-regulate the Notch pathway ligand delta like4 (dll4) and the Notch receptors notch1b, notch2 and notch3. Expression profiling showed that Notch signalling inhibition affects endocardial gene expression and genes related to extracellular matrix remodelling and inflammation. Gain- and loss-of-function experiments revealed that Notch is required for the organization of the endocardium, attenuation of the inflammatory response and cardiomyocyte proliferation. These results demonstrate a novel structural and signalling role for the endocardium during heart regeneration. Overall design: RNA was extracted from apical tip of heart ventricles 72h after cryoinjured adult zebrafish heart treated with DMSO (Controls) or RO gamma secretase inhibitor at 24 and 48h post injury.
