Transcription profiling of wild type and sigma B mutant Liseteria monocytogenes to characterise the EGD-e sigma B regulon

ABSTRACT: Briefly, over night cultures of L. monocytogenes EGD-e cells (wild-type and sigma B mutant) were grown in brain heart infusion (BHI) broth (Difco). Bacteria were diluted 1:50 in 20 ml fresh BHI and incubated using a 100 ml Erlenmeyer flask at 37 °C with shaking (180 rpm, Unitron [Infors]). Bacterial cells were harvested at OD600 1.0 (3 h), OD600 2.0 (4 h), OD600 2.5 (8 h) OD600 2.5 (16 h) using RNAprotect (Qiagen) according to manufacturer.

Transcription profiling of Listeria monocytogenes EGD-e versus the over-expressing strain (EGD-e+pPXrnhB

Project description:Bacteria were grown in BHI until OD600 1.0 (late exponential phase) and RNA stabilized using the RNAprotectTM bacteria reagent (QIAGEN) according to the manufacturer recommendations. For each strain, RNA extraction has been carried out on three independent biological samples. Briefly, bacterial total RNA was isolated, reverse transcribed, hybridised to whole genome microarray and microarray data was analysed as described previously (Chatterjee, 2006). Hybridizations were performed with cDNAs from EGD-e versus the over-expressing strain (EGD-e+pPXrnhB).

Transcription profiling of Listeria monocytogenes EGD-e after heat-shock for 3, 10, 20, and 40 min

Project description:L. monocytogenes EGD-e (Glaser et al., 2001) was grown in Brain Hearth Infusion Broth (Difco) with shaking (200 rpm, New Brunswick C24KC) using 10 ml culture medium in 100 ml conical flasks. An exponentially growing culture was used to inoculate 100 ml of fresh pre-warmed BHI broth in a 500 ml flask. This culture was incubated at 48°C (GFL Type 1083, 60 % shaking speed) and samples for RNA extraction were taken after 3, 10, 20, and 40 min.

Transcription profiling of wild type Listera monocytogenes EGD-e and an isogenic deltahlydeltaplcA mutant strain 1 hour or 4 hours post infection into human intestinal epithelial cells

Project description:We infected wild type L. monocytogenes EGD-e (1) and its isogenic deltahlydeltaplcA (2) (lacking the ability to breach the vacuolar compartment of host cells following uptake) mutant strain to human intestinal epithelial cell line (Caco-2) with an MOI of 100 and 500 respectively. Bacterial total RNA was isolated at 1 h (deltahlydeltaplcA) and 4 h (EGD-e) post infection, reverse transcribed, hybridised to whole genome microarray and microarray data was analysed as described previously (3) 1.

Gene Expression data from Mouse Balb/c Bone marrow derived macrophages infected by the promastigote form of Leishmania major parasite (P) or Killed parasite (Kp) during a time course of infection [Balb/c]

Project description:We analyzed the transcriptional signatures of mouse bone marrow-derived macrophages (BMDM) at different times after infection with promastigotes of the protozoan parasite Leishmania major. GeneChip Mouse Gene 1.0 ST arrays were used to analyse global changes in gene transcripts to generate a pool of genes that was statistically significant (p-value < 0.05) and a fold change cut-off of 1.5 in at least one of the five infected samples versus non-infected samples. Three independent biological replicates for each biological condition (Non infected "NI", infected with lived parasite "P" or "heat inactivated parasite "Kp") at 1h (T1), 3(T3), 6(T6), 12 (T12) and 24hours (T24) were performed. The Non infected (NI) at 0 hour (T0) biological condition were used as an additional control.

Tbr1 regulates regional and laminar identity of postmitotic neurons in developing neocortex

Project description:Areas and layers of the cerebral cortex are specified by genetic programs that are initiated in progenitor cells and then, implemented in postmitotic neurons. Here, we report that Tbr1, a transcription factor expressed in postmitotic projection neurons, exerts positive and negative control over both regional (areal) and laminar identity. Tbr1 null mice exhibited profound defects of frontal cortex and layer 6 differentiation, as indicated by down-regulation of gene-expression markers such as Bcl6 and Cdh9. Conversely, genes that implement caudal cortex and layer 5 identity, such as Bhlhb5 and Fezf2, were up-regulated in Tbr1 mutants. Tbr1 implements frontal identity in part by direct promoter binding and activation of Auts2, a frontal cortex gene implicated in autism. Tbr1 regulates laminar identity in part by downstream activation or maintenance of Sox5, an important transcription factor controlling neuronal migration and corticofugal axon projections. Similar to Sox5 mutants, Tbr1 mutants exhibit ectopic axon projections to the hypothalamus and cerebral peduncle. Together, our findings show that Tbr1 coordinately regulates regional and laminar identity of postmitotic cortical neurons. Mouse E14.5 neocortices and Postnatal day (P) 0.5 brains: E14.5 neocortices KO, 3; E14.5 neocortices WT, 3; Postnatal day (P) 0.5 brains frontal WT, 4; Postnatal day (P) 0.5 brains frontal KO, 4; Postnatal day (P) 0.5 brains parietal WT, 4; Postnatal day (P) 0.5 brains parietal KO, 4; Postnatal day (P) 0.5 brains occipital WT, 4; Postnatal day (P) 0.5 brains occipital KO, 4.
