Transcription profiling of Listeria monocytogenes after infection into murine macrophages
Ontology highlight
ABSTRACT: P388D1 murine macrophages were cultured in 85 mm tissue culture plates to about semi confluency. L. monocytogenes serotypes (1/2a EGD-e, 4a L99, 4b CLIP80459 and 4b F2365) were infected to the P388D1 cell monolayer at a MOI of 100 per eukaryotic cell. Infection was carried for 45 min and followed by addition of fresh medium containing 20 M-5g/ml gentamicin. The medium of the plates (containing 20 M-5g/ml gentamicin) infected with L. monocytogenes serotypes were replaced after 2 h post infection with fresh medium containing 50 M-5g/ml gentamicin. At each step the plates were washed extensively with 1x PBS. Incubation of the bacterial tissue culture plates was carried out in a humidified incubator for up to 4 h post infection.
Project description:Pregnant dams were treated with 0.1% or 0.04% 6-propyl-2-thiouracil (PTU) in drinking water continuously from day 13 post conception until weaning to produce hypothyroid pups. Cerebella were collected from vehicle and 0.1% PTU treated pups at post-natal day (PND) 15 and mRNA from these was subjected to microarray analysis using Agilent high-density oligonucleotide chips.
Project description:In-vitro-cultured seedlings of WT (Col-0) and all possible combinations of single, double, and triple T-DNA insertion mutants of the cytokinin receptors AHK2 (ahk2-5), AHK3 (ahk3-7) and AHK4 (cre1-2) at growth stage 1.00 were treated for 0, 15 and 120 min with 5micromolar of the synthetic cytokinin 6-benzyladednie (BA).
Project description:L. japonicus (Regel) Larsen cv, Gifu were initially obtained from Prof. Jens Stougaard<br>(University Aarhus, Denmark) and then self-propagated at the University of Seville.<br>Seeds were scarified and surface-sterilized,<br>germinated in 1% agar Petri dishes, and transferred to pots using a 1:1 (v/v) mixture<br>of vermiculite and sand as solid support.<br>Five seedlings were planted in each pot and grown<br>during 35 days in a growth chamber under 16/8 hours<br>day/night, 20/18M-oM-?M-=C, with a photosynthetic photon flux<br>density of 250 M-oM-?M-=mol/m2M-oM-?M-=s and a constant humidity of 70%.<br> Plants were watered with Hornum nutrient solution.<br>Drought was applied withholding irrigation for the reported period<br>of time and sample plants or leaves were harvested for further analysis.
Project description:To study the contribution of RNA-binding proteins (RBPs) to the regulation of RNA turnover, we used DNA microarrays to examine the transcriptome of S. pombe strains containing deletions in non-essential genes encoding RBPs
Project description:The Upf1, Upf2 and Upf3 proteins cooperate to implement nonsense-mediated decay. We used DNA microarrays for profiling RNA expression levels of upf2 and upf3 mutants
Project description:The Upf1 protein is a major factor in nonsense-mediated decay. We used an in vivo labelling system (Cleary et al. 2005 Nat Biotechnol. 23, 232-7) to estimate the decay rates of upf1delta and wild type cells over-expressing the transcription factor Mei4.
Project description:To investigate the contribution of RNA-binding proteins to the regulation of RNA decay we used an in vivo labelling system (Cleary et al. 2005 Nat Biotechnol. 23, 232-7) to estimate the decay rates of RBP mutants and wild type S. pombe cells
Project description:Strain PtsP107 has a Tn5 insertion in PtsP and it was grown on glucose/ ammonia minimal medium and gene expression compared to the wild type Rhizobium leguminosarum biovar viciae strain Rlv3841 grown on the same medium.
