Transcriptional profiling of the iron starvation response in Bordetella pertussis provides new insights into siderophore utilization and virulence gene expression.

Journal of bacteriology 20110708 18

Serological studies of patients with pertussis and the identification of antigenic Bordetella pertussis proteins support the hypothesis that B. pertussis perceives an iron starvation cue and expresses multiple iron source utilization systems in its natural human host environment. Furthermore, previous studies using a murine respiratory tract infection model showed that several of these B. pertussis iron systems are required for colonization and persistence and are differentially expressed over t ...[more]

Comparative genomic hybridization of Bordetella bronchiseptica strains RB50 and 1289

Project description:B. bronchiseptica strains RB50 and 1289 strains were grown in SS broth at 37°C with shaking overnight and genomic DNA was isolated from bacterial cultures using a DNA extraction kit (Qiagen, Valencia, CA) and digested with DpnII. For each labeling reaction, 2 ug of digested genomic DNA was randomly primed using Cy-5 and Cy-3 dye-labeled nucleotides, with BioPrime DNA labeling kits (Invitrogen, Carlsbad, CA) and the two differentially labeled reactions to be compared were combined and hybridized to a B. bronchiseptica RB50 specific long-oligonucleotide microarray.

Transcription profiling of human primary cultured fibroblasts from patients with ALMS1 vs healthy patients

Project description:We compared the transcriptional profile of primary cultured fibroblasts obtained from four patients carrying ALMS1 mutation with a pool of primary cultured fibroblasts obtained from three healthy individuals. Gene expression was determined using comparative hybridization perfomed on MicroCRIBI Human Oligonucleotide slides (A-MAXD-4).

Hfq is involved in global protein expression and stress response in Bordetella pertussis

Project description:In this study, we used gel-free nanoLC-MS/MS-based proteomics to compare the protein profile of B. pertussis wild type and an isogenic hfq defective mutant strain under control an iron limited conditions. We found that Hfq affects the abundance of 302 proteins, which represents 8% of the total B. pertussis coding sequence. The absence of Hfq induced changes in the abundance of proteins involved in metabolic pathways, stress response and virulence. Hfq was also found involved in B. pertussis adaptation to iron starvation, one of the main stresses this pathogen faces inside the host. Altogether, these results indicate that B. pertussis Hfq is involved in bacterial physiological processes as well as bacterial pathogenesis.

Transcription profiling of two human paediatric cancer cell lines to identify alternatively spliced variants of Ciz1

Project description:Ciz1 promotes initiation of mammalian DNA replication and is present within nuclear matrix associated DNA replication factories. Depletion of Ciz1 from normal and cancer cells restrains entry to S phase and inhibits cell proliferation. Several alternative splicing events with putative functional consequences have been identified and reported, but many more variants are predicted to exist based on publicly available mRNAs and expressed sequence tags. Here we report the development and validation of a custom exon and exon-junction microarray focused on the human Ciz1 gene, capable of reproducible detection of differential splice-variant expression. Using a pair of paediatric cancer cell lines and a pool of eight normal lines as reference, the array identified expected and novel Ciz1 splicing events. One novel variant (delta 8-12) that encodes a predicted protein lacking key functional sites, was validated by quantitative RT-PCR and found to be over-represented in a range of other cancer cell lines, and over half of a panel of primary lung tumours.
