Affymetrix Human Exon 1.0 ST Array [transcript (gene) version (huex10st)
Description
D122p53 mice (a model of D133p53 isoform) are tumour prone, have extensive inflammation and elevated serum IL-6. To investigate the role of IL-6 we crossed 122p53 mice with IL-6 deficient mice. Here we show that loss of IL-6 reduced JAK-STAT signalling, tumour incidence, and metastasis. We also show that D122p53 activates RhoA-ROCK signalling leading to tumour cell invasion which is IL-6 dependent and can be reduced by inhibition of JAK-STAT and RhoA-ROCK pathways. Similarly, we show that 133p53 activates the these pathways, resulting in invasive and migratory phenotypes, in colorectal cancer cells. Gene expression analysis of colorectal tumours showed enrichment of GPCR signalling associated with D133TP53 mRNA. Patients with elevated D133TP53 mRNA levels had a shorter disease free survival. Our results suggest that D133p53 promotes tumour invasion by activation of the JAK-STAT and RhoA-ROCK pathways and that patients whose tumours have high D133p53 may benefit from therapies targeting these pathways.

- Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
ob/ob mice is an obese mice. CIDE family proteins including Cidea, Cideb and Cidec play important role in lipid metabolism. Cidea is mainly expressed in the brown adipose tissue (BAT). Cidec is mainly expressed in the BAT and white adipose tissue (WAT). We generated ob/ob/Cidea-/-/Cidec-/- mice to investigate the phenotype of fat tissue. ob/ob/Cidea-/-/Cidec-/- mice are lean when compared with ob/ob mice. The tissue weight and TAG content of BAT and WAT was extreamly decreased in ob/ob/Cidea-/-/Cidec-/- mice compared with that in ob/ob mice.

Description
Aortic valve regurgitation (AR) imposes a severe volume overload to the left ventricle (LV) which results in dilation, eccentric hypertrophy and eventually loss of function. Little is known about the impact of AR on LV gene expression. We therefore conducted a gene expression profiling study in the LV of male Wistar rats with chronic (9 months) and severe AR.

Description
Using Affymetrix microarray technology we analyzed the gene expression profiles of the most important pathological categories of bladder cancer in order to detect potential marker genes. Applying an unsupervised cluster algorithm we observed clear differences between tumor and control samples, as well as between superficial and muscle invasive tumors. According to cluster results, the T1 high grade tumor type presented a global genetic profile which could not be distinguished from invasive cases. We described a new measure to classify differentially expressed genes and we compared it against the B-rank statistic as a standard method. According to this new classification method, the biological functions overrepresented in top differentially expressed genes when comparing tumor versus control samples were associated with growth, differentiation, immune system response, communication, cellular matrix and enzyme regulation. Comparing superficial versus invasive samples, the most important overrepresented biological category was growth and, specifically, DNA synthesis and mitotic cytoskeleton. On the other hand, some under expressed genes have been clearly related to muscular tissue contamination in control samples. Finally, we demonstrated that a pool strategy could be a good option to detect the best differentially expressed genes between two compared conditions.

Trans fatty acids (tFAs) may have deleterious, long-term transcriptional effects. To explore that issue, we assessed the effects of the tFA elaidic acid and its cis isomer oleic acid on transcription and, in parallel, on DNA methylation.
