The Sinorhizobium meliloti SmYbeY-dependent transcriptome probed with Sm14kOLI microarrays

ABSTRACT: In this experiment we have compared the transcriptome of the S. meliloti Sm2B3001 strain and that of a mutant derivative lacking the gene encoding the almost ubiquitous bacterial endoribonuclease YbeY. Both, the parent and mutant strains were grown to either exponential or stationary phases in complete TY medium. Total RNA of parent and mutant strains (four replicates in each growth condition) were probed by competitive hybridization on Sm14kOLI microarrays. SmYbeY loss-of-function compromised expression of core energy and RNA metabolism genes, whilst promoting accumulation of motility, late symbiotic and transport mRNAs. Up-regulated transcripts are putative SmYbeY substrates representing both bulk and sRNA-regulated mRNAs.

The Sinorhizobium meliloti NfeR1-dependent transcriptome probed with Sm14kOLI microarrays

Project description:NfeR1 is a S. meliloti sRNA highly expressed in response to osmostress and during the symbiotic interaction of this bacterium with alfalfa plants. We have probed the NfeR1-dependent transcriptome by competitive hybridization on Sm14kOLIGO microarrays of RNA from the wild-type strain Sm2B3001 and from a mutant derivative lacking NfeR1 upon growth in unmodified minimal medium or after 1 h shock with 400 mM NaCl.

Comparison of the transcriptional profiles of Sinorhizobium meliloti wildtype 1021 and two S. meliloti mutants deficient in phospholipid biosynthesis

Project description:S. meliloti genes differently expressed in the wildtype 1021, the phosphatidylethanolamine-deficient mutant CS111, or the phosphatidylcholine-deficient mutant OG10017 were identified by determining and comparing the whole genome transcription profiles of these three strains. Mutants and wildtype present different phenotypes and the molecular bases for these differences was explored by transcriptome analysis.

Transcription profiling of Saccharomyces cerevisiae delta-rsf1mutant during growth on, and transition to growth on glycerol as sole carbon source

Project description:Rsf1p is a putative transcription factor required for efficient growth using glycerol as sole carbon source but not for growth on the alternative respiratory carbon source ethanol. We use microarrays to determine the differences in the transcriptional program between the delta-rsf1 mutant and the wild type during respiratory growth on glycerol as well as the transition to growth on glycerol as sole carbon source. Experiment Overall Design: delta-rsf1or the isogenic parent strain were grown to early log (A600=0.6) in YPD and then washed twice in prewarmed YPG (30 C) and returned to the air shaker in YPG for 15, 30 or 60 minutes. "Limit" conditions were provided by harvesting cells grown in YPD to early log phase without shifting to YPG and by harvesting cells grown in YPG to early log phase. Since the delta-rsf1 mutant and its isogenic parent strain grow equally well on the respiratory carbon source ethanol, cells were also harvested after being grown in ethanol to early log phase.

Noncanonical mRNA decay by the endoplasmic-reticulum stress sensor IRE1-alpha promotes cancer cell survival [RNA-seq]

Project description:Eukaryotic IRE1 mitigates endoplasmic-reticulum (ER) stress by orchestrating the unfolded-protein response (UPR). IRE1 spans the ER membrane, and signals through a cytosolic kinase-endoribonuclease module. The endoribonuclease generates the transcription factor XBP1s by intron excision between similar RNA stem-loop endomotifs, and depletes select cellular mRNAs through regulated IRE1-dependent decay (RIDD). Paradoxically, mammalian RIDD seemingly targets only mRNAs with XBP1-like endomotifs, while in flies RIDD exhibits little sequence restriction. By comparing nascent and total IRE1α-controlled mRNAs in human breast cancer cells, we discovered not only canonical endomotif-containing RIDD substrates, but also many targets lacking recognizable motifs—degraded by a process we coin RIDDLE, for RIDD lacking endomotif. IRE1α displayed two basic endoribonuclease modalities: endomotif-specific cleavage, minimally requiring dimers; and endomotif-independent promiscuous processing, requiring phospho-oligomers. An oligomer-deficient mutant that did not support RIDDLE failed to rescue cancer-cell viability. These results link IRE1α oligomers, RIDDLE, and cell survival, advancing mechanistic understanding of the UPR.
