Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
Cord blood stem cells were expanded and differentiated to NK cells. Samples taken at different days after induction of differentiation were analyzed and compared to undifferentiated expanded stem cells. The most highly upregulated genes were further analyzed.

Description
Cohesin, which consists of SMC1, SMC3, Rad21 and either SA1 or SA2, topologically embraces the chromatin fibers to hold sister chromatids together and to stabilize chromatin loops. Increasing evidence indicates that these loops are the organizing principle of higher-order chromatin architecture, which in turn is critical for gene expression. To determine how cohesin contributes to the establishment of tissue-specific transcriptional programs, we compared genome-wide cohesin distribution, gene expression and chromatin architecture in cerebral cortex and pancreas from adult mice. More than one third of cohesin binding sites differ between the two tissues and these are enriched at the regulatory regions of tissue-specific genes. Cohesin colocalizes extensively with the CCCTC-binding factor (CTCF). Cohesin/CTCF sites at active enhancers and promoters contain, at least, cohesin-SA1 whereas either cohesin-SA1 or cohesin-SA2 are present at active promoters independently of CTCF. Analyses of chromatin contacts at the Protocadherin gene cluster and the Regenerating islet-derived (Reg) gene cluster, mostly expressed in brain and pancreas respectively, revealed remarkable differences in the architecture of these loci in the two tissues that correlate with the presence of cohesin. Moreover, we found decreased binding of cohesin and reduced transcription of the Reg genes in the pancreas of SA1 heterozygous mice. Given that Reg proteins are involved in the control of inflammation in pancreas, such reduction may contribute to the increased incidence of pancreatic cancer reported in these animals.

Description
Genetic factors contribute to the development of ischemic stroke but their identity remains largely unknown. We tested the association with ischemic stroke of 210 single nucleotide polymorphisms (SNPs) associated with pathways functionally related to stroke. We observed an association between the rs7956957 SNP in LRP1 and next performed microarrays analysis in healthy individuals to investigate possible associations of LRP genotypes with the expression of other genes.

Description
Considering the numerous complex and different pathological mechanisms involved in Alzheimers disease (AD) progression, treatments targeting a single cause may lead to limited benefits. The goal of this study was the identification of a novel mode of action for this unmet need. Pharmacological tool compounds: suberoylanilide hydroxamic acid (SAHA) and tadalafil, targeting histone deacetylases (HDAC) and phosphodiesterase 5 (PDE5) respectively, were utilized simultaneously for in-vitro and in-vivo Proof-of-Concept (PoC). A synergistic effect was observed in the amelioration of AD signs using the combination therapy in Tg2576 mice. Finally, a therapeutic agent, CM-414, inhibiting simultaneously HDAC2/6 and PDE5 was generated and tested in Tg2576 mice. CM-414 reversed cognitive impairment, reduced amyloid and tau pathology, and rescued dendritic spine density loss in the hippocampus in AD mice. Importantly, the effect obtained was present after a 4-weeks wash-out period.
