Affymetrix Rat Gene 1.0 ST Array (ragene10st)
Description
Urethra was partially ligated and the urinary bladder was removed 10 days or 6 weeks after obstruction. Sham operated rats were used as controls. An addtitonal group of rats were repoerated 6 weeks after surgery and the obstruction was removed. These rats were then sacrificed 10 days after deobstruction. The bladder (including the urothelium) was frozen and used for RNA extraction.
Publication Title
Mir-29 repression in bladder outlet obstruction contributes to matrix remodeling and altered stiffness.

- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
Aerial parts of the rice-Arabidopsis FOX (Full-length cDNA overexpressor) lines K16331 and K19624 harboring the rice FL cDNA of LBD37 (Os-LBD37) were analyzed. LBD37 belongs to the plant- specific LOB- (Lateral Organ Boundary) domain family proteins first characterized in Arabidopsis. Results point towards an involvement of the rice LBD37 ortholog of Arabidopsis in nitrogen metabolism- related processes.

Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
The 5th and 6th leaf blades of the rice Os-LBD37 overexpressor line RK16331-13 and the empty vector control line FOX3 were examined. LBD37 belongs to the plant- specific LOB- (Lateral Organ Boundary) domain family proteins first characterized in Arabidopsis. Results point towards an involvement of the rice LBD37 (OsLBD37) ortholog of Arabidopsis in nitrogen metabolism- and senescence- related processes.

- Affymetrix Mouse Gene 2.0 ST Array (mogene20st)
Description
Hypertension is a dominating risk factor for cardiovascular disease. To characterize the genomic response to hypertension, we administered vehicle or angiotensin II to mice and performed gene expression analyses. AngII treatment resulted in a robust increase in blood pressure and altered expression of 235 genes in the aorta, including Gucy1a3 and Gucy1b3 which encode subunits of soluble guanylyl cyclase (sGC). Western blotting and immunohistochemistry confirmed repression of sGC associated with curtailed relaxation via sGC activation. Analysis of transcription factor binding motifs in promoters of differentially expressed genes identified enrichment of motifs for RBPJ, a component of the Notch signaling pathway, and the Notch coactivators FRYL and MAML2 were reduced. Gain and loss of function experiments demonstrated that JAG/NOTCH signaling controls sGC expression together with MAML2 and FRYL. Reduced expression of sGC, correlating with differential expression of MAML2 in stroke prone and spontaneously hypertensive rats was also seen and RNA-Seq data demonstrated correlations between JAG1, NOTCH3, MAML2 and FRYL and the sGC subunits GUCY1A3 and GUCY1B3 in human coronary artery. Notch signaling thus provides a constitutive drive on expression of the major nitric oxide receptor (GUCY1A3/GUCY1B3) in arteries from mice, rats, and humans, and this control mechanism is disturbed in hypertension.

Description
Gene expression patterns were assessed in normal human bronchial epithelial (NHBE) cells exposed to cigarette smoke from a reference cigarette (2R4F, University of Kentucky) and a typical American brand of "light" cigarettes ("Lights") in order to develop a better understanding of the genomic impact of tobacco exposure, which can ultimately define biomarkers that discriminate tobacco-related effects and outcomes in a clinical setting. NHBE cells were treated with whole cigarette smoke for 15 minutes and alterations to the transcriptome assessed at 2, 4, 8 and 24 hours post-exposure using high-density oligonucleotide microarrays.
Publication Title
Cigarette smoke induces endoplasmic reticulum stress and the unfolded protein response in normal and malignant human lung cells.

Description
Gene expression patterns were assessed in normal human bronchial epithelial (NHBE) cells exposed to cigarette smoke (CS) from a typical "full flavor" American brand of cigarettes in order to develop a better understanding of the genomic impact of tobacco exposure, which can ultimately define biomarkers that discriminate tobacco-related effects and outcomes in a clinical setting. NHBE cells were treated with CS for 15 minutes and alterations to the transcriptome assessed at 1,2,4 and 24 hours post-CS-exposure using high-density oligonucleotide microarrays.

Description
Tumor tissue heterogeneity is a well known feature of several solid tumors. Neuroblastic Tumors (NTs) is a group of paediatric cancers with a great tissue heterogeneity. Most of NTs are composed of undifferentiated, poorly differentiated or differentiating neuroblastic (Nb) cells with very few or absent Schwannian stromal (SS) cells: these tumors are grouped as Neuroblastoma (Schwannian stroma-poor). The remaining NTs are composed of abundant SS cells and classified as Ganglioneuroblastoma (Schwannian stroma-rich) intermixed or nodular and Ganglioneuroma. The importance to understand Nb and SS gene signatures in NTs, is to clarify the complex network mechanism of tumor growth and progression. In order to identify the Nb and SS cells gene signatures, we analyzed the gene expression profiling of 19 cases of neuroblastic tumors: 10 stroma poor (NTs-SP) and 9 stroma rich (NTs-SR), by high density oligonucleotide microarrays. Moreover, the analysis was performed in parallel on both whole and laser microdissected tumor samples: from 4 of 19 cases, was isolated different areas all composed of pure cellular populations.

Identification of low intratumoral gene expression heterogeneity in neuroblastic tumors by genome-wide expression analysis and game theory.
