Journal of bacteriology 20120224 9

The largest family of toxin-antitoxin (TA) modules are encoded by the vapBC operons, but their roles in bacterial physiology remain enigmatic. Microarray analysis in Mycobacterium smegmatis overexpressing VapC/VapBC revealed a high percentage of downregulated genes with annotated roles in carbon transport and metabolism, suggesting that VapC was targeting specific metabolic mRNA transcripts. To validate this hypothesis, purified VapC was used to identify the RNA cleavage site in vitro. VapC had ...[more]

Transcription profiling of sugarcane mosaic virus (SCMV) resistance in maize

Project description:The molecular mechanisms underlying the development and progression of sugarcane mosaic virus (SCMV) infection in maize are poorly understood. A transcript profiling study based on maize unigene-microarrays was conducted to identify genes associated with SCMV resistance in the near isogenic line (NIL) pair F7+ (SCMV resistant) and F7 (susceptible). Four comparisons were conducted, which is addressing constitutive genetic discrepancy (Non-infected F7 vs. Non-infected F7+), inducible genetic discrepancy (Infected F7 vs. Infected F7+), compatible reaction (Non-infected F7 vs. Infected F7), and incompatible reaction (Non-infected F7+ vs. Infected F7+).

Transcriptomic impact of AWR5 effector expression in S. cerevisiae

Project description:The type III effector (T3E) AWR5 from the phytopathogen Ralstonia solanacearum causes disease in many plants relevant in agriculture. Heterologous expression in yeast of AWR5 from an integrated tetO promoter caused strong growth inhibition. In this series of experiments we investigate the possible changes in the transcriptional profile in a time-course (2, 4 and 6 h) response to AWR5 production. Yeast strains were grown overnight in rich YPD medium with doxycycline 15 Âµg/ml (repressing conditions), then normalized to OD600=0.05 and grown resumed in YPD+dox (non-inducing conditions) or YPD (inducing conditions). Samples were taken at 2, 4 or 6 hours for each condition. Two biological replicates were made for each time point.

Identification and validation of novel ERBB2 (HER2, NEU) targets including genes

Project description:V-erb-b2 erythroblastic leukemia viral oncogene homolog 2 (ERBB2; synonyms HER2, NEU) encodes a transmembrane glycoprotein with tyrosine kinase-specific activity that acts as a major switch in different signal-transduction processes. ERBB2 amplification and overexpression have been found in a number of human cancers, including breast, ovary and kidney carcinoma. Our aim was to detect ERBB2- regulated target genes that contribute to its tumorigenic effect on a genomewide scale. The differential gene expression profile of ERBB2- transfected and wild-type mouse fibroblasts was monitored employing DNA microarrays. Regulated expression of selected genes was verified by RT-PCR and validated by Western blot analysis. Genomewide gene expression profiling identified (i) known targets of ERBB2 signaling, (ii) genes implicated in tumorigenesis but so far not associated with ERBB2 signaling as well as (iii) genes not yet associated with oncogenic transformation, including novel genes without functional annotation. We also found that at least a fraction of coexpressed genes are closely linked on the genome. ERBB2 overexpression suppresses the transcription of antiangiogenic factors (e.g., Sparc, Timp3, Serpinf1) but induces expression of angiogenic factors (e.g., Klf5, Tnfaip2, Sema3c). Profiling of ERBB2-dependent gene regulation revealed a compendium of potential diagnostic markers and putative therapeutic targets. Identification of coexpressed genes that colocalize in the genome may indicate gene regulatory mechanisms that require further study to evaluate functional coregulation. Erbb2 transfected NIH3T3 cells versus un-transfected cells, 4 technical replicates including two colour swap experiments
