Project description:In order to screening the responsive miRNAs and target genes of willow under salt stress, the 30-day-old plants were exposed to the salt solution (100 mmol L-1 NaCl) for 0 h and 2 d. then RNA isolated from root and stem tissues for the same time point were mixed respectively in equal amounts for small RNA (sRNA) sequencing. sRNAs with 16–30 nt were separated from 1 µg total RNA by size fractionation. Subsequently, the selected sRNA fragments were ligated with specialized adaptors to the 5’ and 3’ ends (Illumina) using T4 RNA ligase. Then, the ligated RNAs were reverse transcribed and amplified for sequencing using Illumina Hiseq2500 (LC Sciences, Hangzhou, China). Salt stress-responsive miRNAs were identified by comparing the expression levels of miRNAs between the two libraries. Equal amounts of all 2 RNA samples were mixed together to construct one degradome library, and then sent to Hangzhou LC-Bio Co., Ltd (Hangzhou, China) for sequencing by Illumina Genome Analyzer GA-I (Illumina, San Diego, CA, USA).

Project description:Small Cell Lung Cancer (SCLC) can be classified into transcriptional subtypes with distinct degrees of neuroendocrine (NE) differentiation. Recent evidence supports plasticity among subtypes with a bias toward adoption of low-NE states during disease progression or upon acquired chemotherapy resistance. Here, we identify a role for SMARCA4, the catalytic subunit of the SWI/SNF complex, as a regulator of subtype shift in SCLC. SMARCA4 binds to gene loci encoding NE-lineage transcription factors ASCL1 and NEUROD1 and alters chromatin accessibility, suppressing NE programs. In parallel, SMARCA4 also controls REST, a known suppressor of the NE phenotype, by regulating SRRM4-dependent REST splicing. The SMARCA2/4 inhibitor FHD-286 induces loss of NE features and drives ERBB pathway activation in SCLC, rendering SCLC tumors sensitive to afatinib. This study nominates SMARCA4 as a key regulator of the NE state plasticity and defines a novel therapeutic strategy for SCLC.

Project description:In lung and prostate adenocarcinomas, neuroendocrine (NE) transformation to an aggressive derivative resembling small cell lung cancer (SCLC) is associated with poor prognosis. We previously described dependency of SCLC on the nuclear transporter exportin 1. Here we explored the role of exportin 1 in NE transformation. We observed upregulated exportin 1 in lung and prostate pre-transformation adenocarcinomas. Exportin 1 was induced upregulated following genetic inactivation of TP53 and RB1 in lung and prostate adenocarcinoma cell lines, accompanied by increased sensitivity to the exportin 1 inhibitor selinexor in vitro. Exportin 1 inhibition prevented NE transformation and extended response to targeted therapies in both lung anddifferent TP53/RB1-inactivated prostate adenocarcinoma xenograft models that acquire NE features upon treatment with the AR inhibitor enzalutamide, and extended response to the EGFR inhibitor osimertinib in a lung cancer transformation patient-derived xenograft (PDX) model exhibiting combined adenocarcinoma/SCLC histology. Ectopic SOX2 expression restored the enzalutamide-promoted NE transformationNE phenotype on adenocarcinoma-to-NE transformation xenograft models despite selinexor treatment. Selinexor sensitized NE-transformed lung and prostate small cell carcinoma PDXs tumors after NE transformation to standard cytotoxics. Together these data nominate exportin 1 inhibition as a novel potential therapeutic approach target to constrain lineage plasticity and prevent or treat NE transformation in lung and prostate adenocarcinoma.

Project description:adt12-01_uprt - plant rabt n°1 - Impact of RNA labeling by Plant RABT on plant transcriptome - Determine the incidence of RNA marking by the RABT method Plantation on the plants transcriptome. In several studies Clearly et al. have described a method referred as "4TU tagging" which can be use to study mRNA synthesis and decay either in a mixed population of cells or in a specific cell type (Cleary, Meiering et al. 2005, Zeiner, Cleary et al. 2008, Miller, Robinson et al. 2009, Rabani et al., 2011). Through the specific cell type expression in drosophila and mammalian cells of theToxoplasma gondii uracil PhosphoribosylTransferase activity and the metabolization of the uracil analog 4-thiouracil (4 TU), mRNA were selectively tagged, purified and used in microarray based analysis.

Project description:Chromosome replication and transcription occur within a complex nuclear milieu whose functional subdomains are only beginning to be mapped out. The nuclear envelope (NE) generally interacts with heterochromatic regions of the genome that are inherently difficult to replicate. Here we delineate compositionally and functionally distict domains of the fission yeast NE, focusing on the NE regions specifically enriched for the inner NE protein, Bqt4, or the conserved lamin interacting domain protein, Lem2. Bqt4 is relatively mobile around the NE and acts in two capacities. First, Bqt4 is required for tethering two key heterochromatic regions, the chromosome termini and the mat locus, to the NE specifically while these regions are undergoing DNA replication. This positioning is required for robust replication and heterochromatin assembly in the wake of the replication fork. Second, Bqt4 mobilizes a subset of Lem2 molecules around the NE, where Lem2/Bqt4 promote pericentric heterochromatin maintenance. Opposing Bqt4-dependent Lem2 mobility are factors that stabilize Lem2 at its most abundant localization site beneath the centrosome, where Lem2 plays a crucial role in kinetochore maintenance. Our data prompt a model in which Bqt4-rich nuclear subdomains are ‘safe zones’ in which collisions between transcription and replication are averted and heterochromatin is reassembled faithfully following replication.
