Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
Using the ATH1 Affymetrix microarrays consisting of about 23,000 genes, we examined the response of Arabidopsis seedlings to chito-tetramers, chito-octamers and hydrolyzed chitin after 30 min of treatment.

- Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
The apolipoprotein A-I (apoA-I) mimetic peptide 4F displays prominent anti-inflammatory properties, including the ability to reduce vascular macrophage content. Macrophages are a heterogenous group of cells, represented by two principal phenotypes, the classically activated M1 macrophage and an alternatively activated M2 phenotype. We recently reported that 4F favors the differentiation of human monocytes to an anti-inflammatory phenotype similar to that displayed by M2 macrophages. In the current study, microarray analysis of gene expression in monocyte-derived macrophages (MDMs) was carried out to identify inflammatory pathways modulated by 4F treatment. ApoA-I treatment of MDMs served as a control. Transcriptional profiling revealed that 4F and apoA-I modulated expression of 113 and 135 genes that regulate inflammatory responses, respectively. Cluster heat maps revealed that 4F and apoA-I induced similar changes in expression for 69 common genes. Modulation of other gene products, including STAT1 and PPARG, were unique for 4F treatment. Besides modulating inflammatory responses, 4F was found to alter gene expression in cell-to-cell signaling, cell growth/proliferation, lipid metabolism and cardiovascular system development. These data suggest that the protective effects of 4F in a number of disease states may be due to underlying changes in monocyte/macrophage gene expression.

Description
Very little is known about how intervertebral disc (IVD) is formed or maintained. Members of the TGF- superfamily are secreted signaling proteins that regulate many aspects of development including cellular differentiation. We recently showed that deletion of Tgfbr2 in Col2a expressing tissue results in alterations in development of IVD annulus fibrosus. The results suggested TGF- has an important role in regulating development of the axial skeleton, however, the mechanistic basis of TGF- action in these specialized joints is not known. One of the hurdles to understanding development of IVD is a lack of known markers. To identify genes that are enriched in the developing IVD and to begin to understand the mechanism of TGF- action in IVD development, we undertook a global analysis of gene expression comparing gene expression profiles in developing vertebrae and IVD. We also compared expression profiles in tissues from wild type and Tgfbr2 mutant mice. Lists of IVD and vertebrae enriched genes were generated. Expression patterns for several genes were verified either through in situ hybridization or literature/ database searches resulting in a list of genes that can be used as markers of IVD. Cluster analysis using genes listed under the Gene Ontology terms multicellular organism development and pattern specification indicated that mutant IVD more closely resembled vertebrae than wild type IVD. We propose TGF- has two functions in IVD development: 1) to prevent chondrocyte differentiation in the presumptive IVD and 2) to promote differentiation of annulus fibrosus from sclerotome. We have identified genes that are enriched in the IVD and regulated by TGF- that warrant further investigation as regulators of IVD development.
