- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
Plant organs are comprised of distinct cell types with unique assemblages of mRNAs. This is a collection of CEL files of mRNA profiles of the total steady-state mRNAs and polysomal mRNAs of distinct cell types of the whole root and shoot of 7-d-old Arabidopsis thaliana seedlings. The cell type specific mRNA populations are those present in ribosome-mRNA complexes. This sub-population of mRNAs was obtained by first establishing a collection of Arabidopsis lines that express a FLAG-epitope tagged ribosomal protein L18 (RPL18) directed by promoters expressed in specific cell types and regions. Thirteen different promoter:FLAG-RPL18 lines were used. The targeted cell types and promoters included root atrichoblast (non-hair) epidermal cells (pGL2), root endodermis (pSCR), root stelar xylem and pericycle (pWOL, pSHR), root phloem companion cells (phloem CC) (pSUC2, pSultr2;2), root proliferating cells (pRPL11C), root cortex meristematic cells (pCO2), root cortex elongation/maturation cells (pPEP), shoot mesophyll (pRBCS), shoot epidermis (pCER5), shoot guard cells (pKAT1), shoot bundle sheath (pSultr2;2), shoot phloem CC (pSUC2) and shoot trichomes (pGL2). A CaMV 35S promoter:FLAG-RPL18 line was used to obtain the polysomal mRNA of multiple cell types. The immunopurification of ribosome-mRNA complexes of specific cell types/regions was accomplished by the method described in Zanetti et al. (Plant Physiology, 138, 624-635; 2005). Hybridization of the immunopurified mRNAs to the Affymetrix ATH1 DNA microarray platform and subsequent data analysis permitted the identification of transcripts that are enriched or depleted in specific cell types/regions of roots and shoots. The dataset includes samples from cell types/regions from seedlings grown under control conditions and cell types/regions of seedlings exposed to low oxygen stress (hypoxia) for 2 h.

Description
Plant organs are comprised of distinct cell types with unique assemblages of mRNAs. This is a collection of CEL files of mRNA profiles of the total steady-state mRNAs and polysomal mRNAs of distinct cell types of the root tip of 7-d-old Arabidopsis thaliana seedlings. The cell type specific mRNA populations are those present in ribosome-mRNA complexes. This sub-population of mRNAs was obtained by first establishing a collection of Arabidopsis lines that express a FLAG-epitope tagged ribosomal protein L18 (RPL18) directed by promoters expressed in specific cell types and regions. Four different promoter:FLAG-RPL18 lines were used. The targeted cell types and promoters included root endodermis (pSCR) and root stelar xylem and pericycle (pWOL, pSHR). A CaMV 35S promoter:FLAG-RPL18 line was used to obtain the polysomal mRNA of multiple cell types. The immunopurification of ribosome-mRNA complexes of specific cell types was accomplished by the method described in Zanetti et al. (Plant Physiology, 138, 624-635; 2005). Hybridization of the immunopurified mRNAs to the Affymetrix ATH1 DNA microarray platform and subsequent data analysis permitted the identification of transcripts that are enriched or depleted in specific cell types of root tips. The dataset includes samples from cell types from seedlings grown under control conditions and cell types of seedlings exposed to low oxygen stress (hypoxia) for 2 h.

- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
This study profiles transcriptomic changes of Arabidopsis thaliana Col-0 in response to submergence. This dataset includes CEL files, RMA signal values and MAS5 P/M/A calls from total mRNA populations of plants at 9 to 10 leaf rosette stage. Biological replicates of root and shoot tissues were harvested after 7 h and 24 h of submergence in darkness along with corresponding non-submerged dark controls. To characterize the dark response, non-submerged light controls plants were harvested at the 0 h time point. Quantitative profiling of cellular mRNAs was accomplished with the Affymetrix ATH1 platform. Changes in the transcriptome in response to submergence and early darkness were evaluated, and the data led to identification of genes co-regulated at the conditional and organ-specific level.

- Affymetrix Rice Genome Array (rice)
Description
An ERF transcription factor, Submergence-1A (Sub1A), dramatically enhances the tolerance to prolonged submergence in rice. For instance, rice accessions which lack Sub1A (e.g. M202) die within 7-10 d of complete submergence. By contrast, genotypes which posses Sub1A (e.g. M202(Sub1)) can endure submergence stress for 14 d. In this study, the two near isogenic lines with and without Sub1A were subjected to microarray analysis using Affymetrix Gene Chip technology. This analysis provided beneficial information to elucidate general response to submergence stress and to estimate Sub1A-dependent defense response to the stress at mRNA accumulation level.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Autoantibodies that arise in autoimmunity can be present years to decades prior to the onset of disease manifestations. This suggests that the initial autoimmune trigger involves a peripheral lymphoid component, which then drives disease pathology in local tissues later in life. To explore the impact of early peripheral immune dysregulation on the progression of Sjgrens Syndrome, we blocked the CD40-CD40L pathway in young female NOD.H-2h4 mice at 4 weeks of age with a single injection of anti-CD40L antibody, and collected total salivary gland at the age of week 8, 16 and 24. RNA was extracted and submitted to transcriptome profiling using Affymetrix microarray.

- Affymetrix Bovine Genome Array (bovine)
Description
The bovine chromaffin cell (BCC) is a unique modela highly homogeneous and accessible neuroendocrine cellin which to study gene regulation through first messenger-initiated signaling pathways that are specific to post-mitotic cells. BCCs were treated with tumor necrosis factor (TNF) or pituitary adenylate cyclase activating polypeptide (PACAP), two critical regulators of neural cell transcriptional programming during inflammation that act on TNFR2 and PAC1 receptors, respectively, in post-mitotic neuroendocrine cells. Transcripts which were significantly up regulated by either or both first messenger were identified from microarray analysis using two bovine oligonucleotide arrays (Affymetrix and Agilent) followed by statistical analysis with Partek Genomic suite. Microarray data were combined from the two arrays using qRT-PCR sampling validation, and the first-messenger transcriptome derived from TNF and PACAP signaling were compared. More than 90 percent of the genes up regulated either by TNF or PACAP were specific to a single first messenger. BioBase suite, DIRE and Opossum were used to identify common promoter/enhancer response elements that control the expression of TNF- or PACAP-stimulated genes. Bioinformatic analysis revealed that distinct groups of transcription factors control the expression of genes up regulated by either TNF or PACAP . Most of the genes up regulated by TNF contained response elements for members of the Rel transcription factor family, suggesting TNF-TNFR2 signaling mainly through the NF-kB signaling pathway. On the other hand, the PACAP regulated genes showed no enrichment for any single response element, containing instead response elements for combinations of transcription factors allowing activation through multiple signaling pathways, including cAMP, calcium and ERK, in neuroendocrine cells. Pharmacological strategies for mimicking neuroprotection by either PACAP or TNF in the context of CNS injury or degeneration in disease might focus on individual downstream gene activation pathways to achieve greater specificity in vivo.
