Project description:MLS000408882-01 and MLS000573813-01 were identified through a cell based screen that measures the reactivation of an epigenetically silenced transgene. MLS000408882-01 and MLS000573813-01 shows selectivity for cancer vs. normal cells affecting both transcriptional patterns and cell viability in a cancer specific manner.
Project description:Characterisation of peptide ligands of Major histocompatibility class (MHC) I isolated by immunoaffinity purification from the C1R (Class I reduced) B-lymphoblastoid cell line, transfected with the MHC class I allele HLA-A*01:01, or HLA-A*02:01, HLA-A*24:02. In addition, public mass spectrometry (MS) datasets of HLA-I and HLA-II immunopeptidome derived from patients’ samples, PBMC or cell lines, and shotgun proteomics from trypsin/elastase digestion were analysed.
Project description:UMR106-01 osteoblastic cells are a model for studying bone mineralization. We have shown that mineralization is temporally synchronized within cultures grown under defined conditions . Cells are plated at time zero and differentiate into osteoblastic phenotype by 64 h later. If an exogenous phosphate source is added to the cultures, the cells form and deposit hydroxyapatite mineral within distinct extracellular supramolecular lipid protein complexes termed biomineralization foci (BMF) starting 12 h later. Mineralization is largely complete by 24 h later (88 h after plating). We have also shown that AEBSF, covalent serine protease inhibitor, blocks mineralization within BMF and inhibits the fragmentation of several proteins related to biomineralization. The present experiment was designed to test whether AEBSF treatment for 12 h has an effect on transcription by UMR106-01 osteoblastic cells. AEBSF is known to inactivate several serine proteases including SKI-1 (site 1, subtilisin kexin protease-1).SKI-1 functions intracellularly to activate transmembrane bound transcription factor precursors releasing the transcriptionally active N-terminal portions to imported into the nucleus. Thus, if AEBSF blocks transcription of mineralization related genes, it would support a role for SKI-1 in gene regulation in mineralizing UMR106-01 osteoblastic cells.
Project description:GAS2DN could suppress the growth of chronic myeloid leukemia cells, including K562, MEG-01 and CD34+ cells from patients. In addition, GAS2DN inhibited the tumorigenic ability of MEG-01 cells in nude mice. To understand the molecular insight of this inhibitory effect of GAS2DN, global gene expression were performed. The control and GAS2DN-transduced MEG-01 cells were used for microarray analysis.
Project description:To investigate global changes in gene expression patterns following treatment with DSCG or MCS-01 we performed RNA-sequencing and nanostring profiling analyses on Day 10 wounds. Differential expression analysis on pre-MCS-01 samples compared to blank identified 649 significantly altered genes at p value <0.05 and absolute fold change >=2. Similarly, in post-MCS-01 samples 954 genes were differentially expressed, of which 566 were down- and 388 up-regulated. DCSG treatment resulted in differential expression of 91 genes. RT-qPCR corroborated increased expression of NFκB and STAT3 with post-MCS-01 treatment. In addition, we compared miRNA expression between MCS-01 samples and controls. Pre-treatment significantly altered expression of 11 miRNAs, while post-treatment altered expression of 28 miRNAs. RT-qPCR confirmed miR-34c upregulation, while significant inverse correlations were found between miR-34c and selected target genes Lef-1, Myb, and Mycn.
Project description:We identified a small molecule, orally active ER-464195-01, inhibits the calreticulin binding to alpha integrins, and clearly suppresses the adherence ability of leukocytes. Our transcriptome analysis with the colon of dextran sodium sulfate (DSS)-treated mice reveals that the increased expression of pro-inflammatory genes was down-regulated by ER-464195-01. Purpose: To gain insight into the molecular mechanisms underlying the prevention of DSS-induced colitis conferred by treatment of ER-464195-01, we performed a comprehensive analysis of ER-464195-01-mediated gene expression changes in DSS-induced colitis using RNA sequencing (RNA-Seq). Methods: Male Balb/c mice (7 weeks) were allowed free access to distilled water (Otsuka Pharmaceutical) containing 2% DSS (molecular weight: 36,000–50,000; ICN Biomedicals) for 6 days to induce colitis. ER-464195-01 (10 mg/kg) or vehicle was orally administered once per day for 6 days. Results: To investigate differentially expressed genes (false discovery rate (FDR) p<0.05, fold change >2) among three groups, we performed pairwise comparisons of RNA-Seq data using the CLC Genomics Workbench software. In comparison with the control, 5,570 (3,483 up- and 2,087 down-regulated) unique genes were significantly changed in the DSS-induced colitis group. Meanwhile, the data set of DSS-induced colitis with ER-464195-01 groups revealed significant changes in 1,808 (837 up- and 971 down-regulated) genes as compared with DSS alone. Notably, of 3,483 genes up-regulated by the DSS treatment, 894 transcripts of which were overlapped with 971 genes down-regulated genes by ER-464195-01.

Project description:Verticillium dahliae Kleb., a soil-borne fungus that colonizes vascular tissues, induces wilting, chlorosis and early senescence in potato. Difference in senescence timing found in two diploid potato clones, 07506-01 and 12120-03, was studied and genetic variation in response to V. dahliae infection was identified as a causal factor. The clone, 07506-01, was infected with V. dahliae but did not develop symptoms, indicating tolerance to the pathogen. The other diploid clone, 12120-03 had low levels of pathogen with infection and moderate symptoms indicating partial resistance. 07506-01 was found to carry two susceptible alleles of the Ve2 gene and 12120-03 carried one Ve2 resistant and one susceptible allele. Infected leaves of the two clones were compared using gene expression profiling with the Potato Oligonucleotide Chip Initiative (POCI) microrarray. The results provide further evidence for differences in response of the two clones to infection with V. dahliae. Chlorophyll biosynthesis was higher in the tolerant 07506-01 compared to partially resistant 12120-03. On the other hand, expression of fungal defense genes, Ve resistance genes and defense phytohormone biosynthetic enzyme genes was decreased in 07506-01 compared to 12120-03 suggesting defense responses were suppressed in tolerance compared to resistance. Transcription factor gene expression differences pointed to the WRKY family as potential regulators of V. dahliae responses in potato.
