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.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
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.

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.

Description
Maslinic acid is a novel phytochemical reported to exert prominent anti-cancer effects and it was hypothesized that this compound induces cellular apoptosis through the activation of the mitochondrial apoptotic pathway (Martin et al, 2007) thereby resulting in significant inhibition of cell proliferation in a dose-dependent manner (Reyes-Zurita et al, 2009). Prior studies on maslinic acid in its function as a time-dependent inhibitor in both tumorigenesis and inflammation events by targeting multiple signaling pathways; particularly the NF-B, MAPK (Li et al, 2010; Yap, et al, 2011) and JNK (Reyes-Zurita et al, 2011) pathways were mostly based on proteomic analyses (Li et al, 2010; Yap et. al., 2011). However, these results may not depict an accurate scenario of the signaling networks involved due to protein degradation, alternate splicing and extensive post-translational processing. Hence, this study aimed to construct a temporal-based global gene expression profile of the effects of maslinic acid by using the microarray technology.
