Affymetrix Human Gene 2.0 ST Array (hugene20st)
Description
A lactobacilli dominated microbiota in most pre and post-menopausal women is an indicator of vaginal health. A Nugent scoring system serves as a proxy for determining the ratio of lactobacilli to other vaginal inhabitants where a high score usually represents a diseased state, whilst an intermediate score represents a warning zone. The objective of this double blinded, placebo-controlled crossover study was to evaluate in 14 post-menopausal women with an intermediate score, the effect of vaginal administration of probiotic L. rhamnosus GR-1 and L. reuteri RC-14 on the microbiota and host response. The probiotic treatment did not result in changes to clinical parameters such as dryness, irritation and comfort, compared to when placebo was applied. Analysis using 16S rRNA sequencing and metabolomics profiling revealed that the proportional abundance of Lactobacillus was increased following probiotic administration as compared to placebo, which was weakly associated with an increase in lactate levels. Analysis of host responses by microarray showed the probiotics had an immune-modulatory response and multiplex cytokine analysis showed up-regulation of IL-5. This is the first study to use an interactomic approach for the study of vaginal probiotic administration in post-menopausal women. It shows that in some cases multifaceted approaches are required to detect the subtle trigger molecular changes induced by the host to instillation of probiotic strains.

Description
The onset of menopause is accompanied by a dramatic increase in reported symptoms of vaginal dryness, soreness, irritation or itching, pain with intercourse and bleeding after intercourse. Collectively these affect 25-50% of women of post-menopausal age and significantly impact their quality of life. To examine how gene expression differs between these groups, surface vaginal epithelial cells were collected from postmenopausal women suffering from vaginal dryness and appropriate controls not suffering from dryness.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Pseudoautosomal regions (PAR1 and PAR2) in eutherians retain homologous regions between the X and Y chromosomes that play a critical role in the obligatory X-Y crossover during male meiosis. Genes that reside in the PAR1 are exceptional in that they are rich in repetitive sequences and undergo a very high rate of recombination. Remarkably, murine PAR1 homologs have translocated to various autosomes, reflecting the complex recombination history during the evolution of the mammalian X chromosome. We now report that the SNF2-type chromatin remodeling protein ATRX controls the expression of eutherians ancestral PAR1 genes that have translocated to autosomes in the mouse. In addition, we have identified two potentially novel mouse PAR1 orthologs. We propose that the ancestral PAR1 genes share a common epigenetic environment that allows ATRX to control their expression.

- Affymetrix Rat Genome 230 2.0 Array (rat2302)
Description
Gene expression profiles of granulosa cells from rat ovarian follicles by Affymetrix rat whole genome array showed that twelve genes were up-regulated, while one gene down-regulated more than 1.5 folds in the normal developmental competence group compared with those in the poor developmental competence group. Gene ontology classification showed that the up-regulated genes included lysyl oxidase and nerve growth factor receptor associated protein 1, which are important in the regulation of protein-lysine 6-oxidase activity, and in apoptosis induction, respectively. The down-regulated genes included glycoprotein-4-beta galactosyltransferase 2, which is involved in the regulation of extracellular matrix organization and biogenesis.

Description
Severe asthma exacerbations in children requiring hospitalisation are typically associated with viral infection, and occur almost exclusively amongst atopics, but the significance of these comorbidities is unknown. We hypothesised that underlying interactions between immunoinflammatory pathways related to responses to aeroallergen and virus are involved, and that evidence of these interactions is detectable in circulating cells during exacerbations.
Publication Title
Interactions between innate antiviral and atopic immunoinflammatory pathways precipitate and sustain asthma exacerbations in children.

Description
Gallic acid (also known as 3,4,5-trihydroxybenzoic acid, GA), a naturally occurring phenolic acid, is a major constituent of tea and red wine. It has been demonstrated that GA possess anti-cancer activities. We found the epigenetic effect of GA in tobacco-associated human cancer cell lines.

Description
As LRIG1 known to be a negative regulator of EGFR, we postulate that restored LRIG1 expression will change the transcription profile through the regulation of EGFR as well as its downstream signal cascades. Thus, we conducted a time-course microarray study to examine the effect of restored LRIG1 expression in NPC line, TW01-LG1/a, which the LRIG1 expression is under the control of a promoter with Doxycycline response element.

Description
Baseline glucocorticoid resistance profiles were measured in a panel of 15 paediatric T-Cell acute lymphoblastic leukaemia cell lines and correlated with Affymetrix Gene expression to identify genes and pathways associated with drug resistance in T-ALL. The cell lines' resistance to Methylprednisolone (MPRED) and Dexamethasone (DEX) was then tested using the MTT assay and IC50 values (drug concentration lethal to 50% of cells) for each drug were calculated.

Description
Dendritic cells differentiate from their precursors in the airway mucosa under local environmental instruction. Airway epithelial cells (AEC) are a potent source of both pro- and anti-inflammatory mediators and are in intimate contact with intraepithelial DC and their precursors. Thus, AEC are likely candidates for influencing this differentiation process in order to tailor the DC for optimal function in the airway mucosa.
