Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
When compared to skin, oral mucosal wounds heal rapidly and with reduced scar formation. This study used an Affymetrix microarray platform to compare the transcriptomes of oral mucosa and skin wounds in order to identify critical differences in the healing response at these two sites.
Publication Title
Positional differences in the wound transcriptome of skin and oral mucosa.

- Affymetrix Human Transcriptome Array 2.0 (hta20)
Description
The mechanisms by which the epidermis responds to disturbances in barrier function and restores homeostasis are unknown. With a disruption of the epidermal barrier, water is lost resulting in an increase in extracellular sodium concentration. We demonstrate that the sodium channel Nax functions as the sodium sensor. With increased extracellular sodium, Nax up-regulates prostasin which results in activation of the sodium channel ENaC, resulting in increased sodium flux and increased downstream mRNA synthesis of inflammatory mediators. The same pathways are present in lung epithelial cells.
Publication Title
Sodium channel Nax is a regulator in epithelial sodium homeostasis.

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.

- Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
Multiple myeloma (MM) is a malignant disorder characterized by the clonal proliferation of plasma cells (PCs) in the bone marrow (BM). The genetic background and clinical course of the disease are largely heterogeneous, and MM pathophysiology ranges from the premalignant condition of monoclonal gammopathy of undetermined significance (MGUS) to smoldering MM, symptomatic MM, and extramedullary MM/plasma cell leukemia (PCL). Recent genome-wide sequencing efforts have provided the rationale for molecularly aimed treatment approaches, identifying mutations that can be specifically targeted, such as those in the mitogen-activated protein kinase (MAPK) pathway, which represent the most prevalent mutations in MM. Among these, mutations affecting BRAF gene, detected in 4-15% of patients, are of potential immediate clinical relevance due to the availability of effective inhibitors of this serine-threonine kinase which are in fact being explored also in myeloma.
