Quantitative mRNA profile of eif3e (yin6, int6) deleted S. pombe cells

ABSTRACT: Int6/yin6 encodes the eIF3e subunits of the eukaryotic translation initiation factor 3 complex (eIF3). To assess the impact of eIF3e on the global transcriptome, RNA seq of total mRNA was performed. Total RNA was prepared from wildtype S. pombe (h- ura4-D18 leu1-32) and cells deleted for eif3e (int6, yin6, SPBC646.09c; h- int6::kanMX6 ura4-D18 leu1-32). Following rRNA depletion and library construction, samples were sequenced on the SOLID4 platform. Two replicates were analyzed and statistical analysis was performed to identify significant differences in mRNA levels.

Whole-genome resequencing of wildtype and EMS-treated fission yeast Schizosaccharomyces pombe

Project description:This experiment aims at analyzing crossover distribution genome-wise, in the fission yeast. S. pombe strains PR109 (h- leu1-32 ura4-D18) and PR110 (h+ leu1-32 ura4-D18) were used for three successive rounds of mutagenesis with Ethylmethane Sulfonate Mutagenesis. Five independent clones of the first round of mutagenesis were at the root of two subsequent similar rounds of mutagenesis. Each clone used was checked for its ability to mate and sporulate. Eventually, five mutagenized clones from each of the PR109 and PR110 backgrounds were sequenced to identify de novo mutations and determine the optimal combinations of mutation patterns for recombination analyses.

Gene Expression Analysis of Cancer-Associated Fibroblast (CAF) compared to Normal Fibroblast (NF) [RNA-seq]

Project description:Analysis of differentially expressed genes in CAF associated with PDAC vs NF. Genetically engineered mice with spontaneous pancreas cancer were generated. Their genotype is Ptfa-cre/+:LSL KrasG12D/+;Tgfrb2flox/flox. Cancer associated fibroblasts were expanded in vitro from the tumors of these mice (CAF). Normal fibroblasts (NF) were also expanded from normal pancreas of mice. The experiement consists in comparing the expression profile of CAF vs. NF. Expanded cultures of fibroblasts in vitro from pancreas tumor and normal pancreas tissue were lyzed in TRIzol and RNA extracted from them.

Cathepsin K Contributes to Cavitation and Collagen Turnover in Pulmonary Tuberculosis

Project description:Cavitation in tuberculosis (TB) enables highly efficient person-to-person aerosol transmission. Currently, a number of hypotheses exist regarding the mechanisms underlying this process. To explore this process, we undertook an unbiased next-generation transcriptional analysis of samples from cavity walls, grossly normal tissue from the same lung, and uninfected control lungs. Of 17,318 mapped host transcripts, only 199 showed a significant >2-fold change in cavity wall versus normal infected and uninfected samples. Amongst 22 upregulated proteases, 5 type I collagenases were over-represented; these included cathepsin K (CTSK), mast cell chymase-1 (CMA1), matrix metalloproteinase (MMP)-1, MMP-13, and MMP-14. To determine if cavitation was associated with changes in collagen turnover, we assayed serum and urinary markers of collagen metabolism in rabbits with cavitary TB versus infected controls. Serum collagen type 1 C-terminal propeptide (CICP, a marker of collagen synthesis and degradation) and urinary deoxypyridinoline (DPD, a marker of degradation) were increased by 10- (p = 0.019) and 4-fold (p = 0.068), respectively; while urinary helical peptide (a marker of degradation) was decreased 3-fold (p=0.015). This indicates that cavitation in TB is associated with significant increases of both destruction and synthesis of collagen and that cleavage of type I collagen occurs outside the known cleavage sites of MMP-1, -13 and -14. Rabbit gene expression analysis in lung tissue from M. tuberculosis infected animals. Cavitary tissue, non cavitary tissue and lung tissue from non-infected animals are compared.

eIF3 PAR-CLIP in 293T cells

Project description:Regulation of protein synthesis is fundamental for all aspects of eukaryotic biology by controlling development, homeostasis, and stress responses. The 13-subunit, 800-kDa eukaryotic initiation factor 3 (eIF3) organizes initiation factor and ribosome interactions required for productive translation. However, current understanding of eIF3 function does not explain genetic evidence correlating eIF3 deregulation with tissue-specific cancers and developmental defects. Here we report the genome-wide discovery of human transcripts that interact with eIF3 using photo-activatable crosslinking and immunoprecipitation (PAR-CLIP). eIF3 binds to a highly specific programme of messenger RNAs (mRNAs) involved in cell growth control processes, including cell cycling, differentiation, and apoptosis, via the mRNA 5' untranslated region (5' UTR). Surprisingly, functional analysis of the interaction between eIF3 and two mRNAs encoding cell proliferation regulators, c-Jun and BTG1, reveals that eIF3 employs different modes of RNA stem loop binding to exert either translational activation or repression. Our findings illuminate a new role for eIF3 in governing a specialized repertoire of gene expression and suggest that binding of eIF3 to specific mRNAs could be targeted to control carcinogenesis. 293T cells were treated with 4-thiouridine and protein-RNA complexes were crosslinked, and eIF3-RNA complexes were immunoprecipitated.

RNA-sequencing of Nedd4+/+ and Nedd4-/- mouse splenic B cells

Project description:Programmed mutagenesis of the immunoglobulin locus of B-lymphocytes during class switch recombination and somatic hypermutation requires RNA polymerase II (RNA polII) transcription complex dependent targeting of the DNA mutator, Activation Induced cytidine Deaminase (AID). AID deaminates cytidine residues on substrate sequences in the immunoglobulin (Ig) locus via a transcription-dependent mechanism and this activity is stimulated by the RNA polII stalling co-factor Spt5 and the eleven-subunit cellular non-coding RNA 3’-5’ exonucleolytic processing complex, RNA exosome. The mechanism by which the RNA exosome recognizes immunoglobulin locus RNA substrates to stimulate AID DNA deamination activity on its in vivo substrate sequences is an important question. Here we report that E3-ubiquitin ligase Nedd4 destabilizes AID-associated RNA polII by a ubiquitination event leading to generation of 3’-end free RNA exosome RNA substrates at the Ig locus and other AID target sequences genome-wide. Using highthrough-out RNA sequencing technology, we find that lack of Nedd4 activity in B cells leads to accumulation of RNA exosome substrates at AID target genes. Moreover, we find that Nedd4-deficient B cells are inefficient in undergoing class switch recombination. Taken together, our study links non-coding RNA processing following RNA polymerase II pausing with regulation of the mutator AID protein. Our study also identifies Nedd4 as a regulator of non-coding RNA that are generated by stalled RNA polII genome-wide. Splenic B cells from Nedd4+/+ and Nedd4-/- B cells fetal liver chimeric mice were were stimulated in culture for IgG1 CSR. Total RNA was isolated and evaluated with whole genome RNA-seq
