- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Samples were taken from colorectal cancers in surgically resected specimens in 35 colorectal cancer patients. The expression profiles were determined using Affymetrix Human Genome U133 Plus 2.0 arrays. Comparison between the sample groups allow to identify a set of discriminating genes that can be used for molecular markers for CIN phynotype.

Description
Specimens were obtained from non-neoplastic colorectal mucosa for RNA ayalysis. Samples were obtained either from surgically resected specimens or during surveillance coloscopy. The expression profiles were determined using Affymetrix Human Genome U133 Plus 2.0 arrays.The correlation between mtDNA CNV and mitochondria-related gene expressions were investigated.

Description
Early onset sepsis due to Group B streptococcus (GBS) leads to neonatal morbidity, increased mortality and long term neurological deficencies. Interaction between septicemic GBS and confluent monlayers of human coronary artery endothelial cells (HCAEC) was analyzed by a genome wide expression profiling. Regulation of selected genes and proteins identified in the gene array analysis was confirmed by Real Time RT-PCR assay (Granulocyte chemotactic protein 2 (CXCL6)), ELISA (Urokinase, Cyclooxygenase 2 (COX2), Granulocyte chemotactic protein 1 (IL8)) and Western Blotting (Heme oxygenase1, BCL2 interacting protein (BIM)) at various time points between 4 and 24 hours. In total, 124 genes were differentially regulated (89 upregulated, 35 downregulated) based on a more than 3-fold difference to unstimulated HCAEC. Regulated genes are involved in apoptosis, hemostasis, oxidative stress response, infection and inflammation. We confirmed upregulation of urokinase (UPA), COX2, HMOX1 and BCL2 interacting protein and downregulation of CXCL6 and IL8. These results indicate that GBS infection might lead to impaired function of the innate immune system and might contribute to hemorrhagic and inflammatory complications during GBS sepsis.

Description
The development and severity of inflammatory bowel diseases (IBD) and other chronic inflammatory conditions can be influenced by host genetic and environmental factors, including signals derived from commensal bacteria. However, the mechanisms that integrate these diverse cues remain undefined. Here we demonstrate that intestinal epithelial cells (IECs) isolated from IBD patients exhibit decreased expression of the epigenome-modifying enzyme histone deacetylase 3 (HDAC3). Further, genome-wide analyses of murine IECs that lack HDAC3 (HDAC3IEC) revealed that HDAC3 deficiency resulted in dysregulated gene expression coupled with alterations in histone acetylation. Critically, conventionally-housed HDAC3IEC mice demonstrated loss of Paneth cells, impaired IEC function and alterations in the composition of intestinal commensal bacteria. In addition, HDAC3IEC mice exhibited significantly increased susceptibility to intestinal damage and inflammation, indicating that epithelial expression of HDAC3 plays a central role in maintaining intestinal homeostasis. Strikingly, rederivation of HDAC3IEC mice into germ-free conditions revealed that dysregulated IEC gene expression, Paneth cell homeostasis, and intestinal barrier function were largely restored in the absence of commensal bacteria. Collectively, these data indicate that the HDAC3 is a critical factor that integrates commensal bacteria-derived signals to calibrate epithelial cell responses required to establish normal host-commensal relationships and maintain intestinal homeostasis.

Description
We previously showed that a diet containing phloridzin suppressed the blood glucose levels in streptozotocin-induced diabetic mice most likely by inhibiting glucose absorption from the small intestine. In this study, we showed that 0.5% and 1% phloridzin diets significantly reduce the blood glucose levels in healthy normal BALB/c mice after 7 days of feeding.
Publication Title
Phloridzin reduces blood glucose levels and alters hepatic gene expression in normal BALB/c mice.
