Description
The Ts1Cje mouse model of Down syndrome (DS) has partial triplication of mouse chromosome 16 (MMU16), which is partially homologous to human chromosome 21. The mouse model develops various neuropathological features identified in DS individuals. We analysed the effect of partial triplication of the MMU16 segment on global gene expression in the cerebral cortex, cerebellum and hippocampus of Ts1Cje mice at 4 time-points; postnatal day (P)1, P15, P30 and P84.
Publication Title
Functional transcriptome analysis of the postnatal brain of the Ts1Cje mouse model for Down syndrome reveals global disruption of interferon-related molecular networks.

Description
Candida species is a common fungus that had evolved as both commensal and opportunistic pathogen in humans. The rise in human morbidity and mortality caused by Candida species sparked an alarming concern. However, the thin line between commensalism and infection as well as the analysis of Candida host-pathogen interactions has not been completely elucidated prior to the birth of global gene expression technologies. Gene expression analysis of host response upon systemic candidiasis had been carried out using Beadarray and validated by using GenomeLab GeXP multiplex PCR. Whole blood from infected mouse was isolated, globin mRNA depleted through subtractive hybridization and its RNA purified. Results from microarray data demonstrated increased expression of genes involved in the pathogen recognition, signal transduction, inflammation, microbial killing and in antigen processing. Interestingly, we also discovered possible increment of erythropoiesis in our animal model and this lead us to believe that Candida tropicalis might possess potent haemolytic factors to sequester iron from the host erythrocytes. Taken together, our data also suggest novel genes such as syndecans and dendritic cell immunoreceptor which might be exploited by Candida tropicalis in its pathogenesis in the host. Nevertheless, the challenge ahead is to understand the specific roles of these genes that underlies in Candida tropicalis pathogenesis.

- Affymetrix S. aureus Genome Array (saureus)
Description
From a Caenorhabditis elegans - S. aureus anti-infective screen, we identified benzimidazole derivative C162 as one of the potential anti-infective candidate that rescued the infected-nematodes from infection. This compound was found to exhibit anti-biofilm activity against S. aureus. To investigate the transcriptome profile of S. aureus in response to benzimidazole derivative C162, a genome-wide transcriptome analysis was performed on C162-treated S. aureus using the Affymetrix GeneChip S. aureus Genome Arrays. Our main interest is to look at the expression profiles of the biofilm-associated and virulence genes.

Description
Background: Even though much progress has been made in the understanding of the molecular nature of glioma, the survival rates of patients affected of this tumour have not changed significantly during these years. Thus, a deeper understanding of this malignancy is still needed in order to predict its outcome and improve patient treatment. Here, we report that VAV1, a GDP/GTP exchange factor for Rho/Rac proteins with oncogenic potential that is involved in the regulation of cytoskeletal dynamics and cell migration.

Affymetrix Mouse Expression 430A Array (moe430a)
Description
Cellular stress responses can be activated following functional defects in organelles such as mitochondria and the endoplasmic reticulum. Mitochondrial dysfunction caused by loss of the serine protease HtrA2 leads to a progressive movement disorder in mice and has been linked to parkinsonian neurodegeneration in humans. Here we demonstrate that loss of HtrA2 results in transcriptional up-regulation of nuclear genes characteristic of the integrated stress response, including the transcription factor CHOP, selectively in the brain. We also show that loss of HtrA2 results in the accumulation of unfolded proteins in the mitochondria, defective mitochondrial respiration and enhanced production of reactive oxygen species that contribute to the induction of CHOP expression and to neuronal cell death. CHOP expression is also significantly increased in Parkinsons disease patients brain tissue. We therefore propose that this brain-specific transcriptional response to stress may be important in the advance of neurodegenerative diseases.
