Affymetrix Human Genome U133A Array (hgu133a)
Description
Microarray is widely used to monitor gene expression changes in breast cancer. The transcriptomic changes in breast cancer is commonly occured during the transition of normal cells to cancerous cells. This is the first study on gene expression profiling of multi ethnic of Malaysian breast cancer patients (Malays, Chinese and Indian). We aim to identify differentially expressed genes between tumors and normal tissues. We have identified a set of 33 significant differentially expressed genes in the tumor vs. normal group at p<0.001.
Publication Title
Gene expression patterns distinguish breast carcinomas from normal breast tissues: the Malaysian context.

Illumina HiSeq 4000
Description
In response to viral pathogens, the host upregulates antiviral genes that suppress translation of viral mRNAs. However, induction of such antiviral responses may not be exclusive to viruses as the pathways lie at the intersection of broad inflammatory networks that can also be induced by bacterial pathogens. Using a model of Gram-negative sepsis, we show that propagation of kidney damage initiated by a bacterial origin ultimately involves antiviral responses that result in host translation shutdown. We determined that activation of the Eif2ak2-Eif2a axis is the key mediator of translation initiation block in late phase sepsis. Reversal of this axis mitigated kidney injury. Furthermore, temporal profiling of the kidney translatome revealed that multiple genes involved in formation of the initiation complex were translationally altered during bacterial sepsis. Collectively, our findings implicate that translation shutdown is indifferent to the specific initiating pathogen and is an important determinant of tissue injury in sepsis. Overall design: Bulk 20 um thickness specimens from cross-sectional human kidney biopsies embedded in OCT underwent RNA sequencing. All subjects had ATN, AIN, or a mix of both conditions.

- Affymetrix Human Gene 2.1 ST Array (hugene21st)
Description
Pyrrole-imidazole polyamides (PIPs) have been shown to inhibit gene expression by interrupting the DNA-protein interface. Human Ectopic viral integration site 1 (EVI1) is an oncogenic transcription factor which plays a key role in many aggressive forms of cancer. We have developed a novel pyrroleimidazole polyamide, PIP1 targeting the REL/ELK1 binding site in the EVI1 minimal promoter that can significantly repress the expression of EVI1 in MDA-MB-231 cells. Whole-transcriptome analysis revealed that a fraction of EVI1-driven genes were modulated by PIP1.
Publication Title
Targeted suppression of EVI1 oncogene expression by sequence-specific pyrrole-imidazole polyamide.

Description
Purpose: Next-generation sequencing (NGS) has revolutionized systems-based analysis of abiotic stress molecular pathways. The goals of this study are to compare NGS-derived transcriptome profiling (RNA-seq) of contrasting slow wilting lines to quantify transcript abumdance under drought stress condition Overall design: Methods: The three biological replicates of DS line, Pana (control and drought samples) and DT line, PI 567690 (control and drought samples) leaf sample RNA were multiplexed and sequenced on an Illumina Hi-Seq 2000 platform. The RNA concentration of each sample was approximately 200ng/µl with a quantity of 50 µl.isoform level with two methods: Burrows–Wheeler Aligner (BWA) followed by ANOVA (ANOVA) and TopHat followed by Cufflinks. qRT–PCR validation was performed using TaqMan and SYBR Green assays

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Interstitial cells of Cajal (ICC) are electrical pacemakers and mediators of neuromuscular neurotransmission in the gastrointestinal tract. Gastrointestinal stromal tumors (GIST) arise within the ICC lineage due to activating KIT/PDGFRA mutations. In this study we developed a method for isolation of human ICC by immunolabeling and fluorescence-activated cell sorting (FACS). Briefly, human gastric musculature was dissociated and incubated with antibodies against CD45, FCER1A, CD11B, KIT, and CD34. ICC (defined as HP-KIT+CD34- cells), NOT ICC (defined as HP-KIT-CD34- cells), and hematopoietic (HP) cells (defined as HP+ cells) were isolated using FACS. Microarray was performed on ICC, NOT ICC, HP+ cells, and unfractionated gastric tunica muscularis. This study utilized micorarray for the phenotypic characterization of FACS-sorted human ICC, allowing comparison of ICC to other cells of the gastric musculature, including GIST.

- Affymetrix Maize Genome Array (maize)
Description
Phytophthora cinnamomi is a devastating soil-borne oomycete with a very broad host range however there remains a major gap in the understanding of plant resistance responses to the pathogen, furthermore, necrotrophic plant-pathogen interactions, particularly those of root pathogens, remain poorly understood. Zea mays exhibits non-host resistance to the pathogen and has been well characterised as a model species. Using the maize Affymetrix GeneChip array we conducted genome-wide gene expression profiling to elucidate the defence genes and pathways which are induced in the root tissue of a resistant plant species to the pathogen.
