Affymetrix Human Genome U133A 2.0 Array (hgu133a2)
Description
Diamond-Blackfan Anemia (DBA) is a rare inherited red cell hypoplasia characterized by a defect in the maturation of erythroid progenitors and is in some cases associated to malformations. Patients have an increased risk of solid tumors. Mutations have been found in several ribosomal protein (RP) genes. Studies in hematopoietic progenitors from patients show that the haploinsufficiency of an RP impairs rRNA processing and ribosome biogenesis. DBA lymphocytes and fibroblasts show reduced protein synthesis, and the latter display abnormal rRNA processing and impaired proliferation.
Publication Title
Fibroblasts from patients with Diamond-Blackfan anaemia show abnormal expression of genes involved in protein synthesis, amino acid metabolism and cancer.

- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
Approximately 2.5 mg dry Col-0 seedlings were surface sterilized and stratified for 2 days at 4degreesC in liquid media containing 1.5% sucrose (w/v) before being transferred to light with constant shaking at 100 rpm on an orbital shaker. After 7 days, the seedling clusters were subjected to the treatments for 1 hr followed by total RNA isolation using the RNAqueous kit (Ambion). Each treatment was performed in triplicate or quadruplicate. All labeling (Enzo) and hybridization (Affymetrix) procedures were performed as directed by the manufacturers. Raw probe intensities output by the Affymetrix MAS software were processed using the RMA algorithm to obtain an expression measure for each gene on each array.

Description
Leukemia stem cells (LSCs) are an attractive target in treatment of many types of blood cancers. There remains an incomplete understanding of the epigenetic mechanisms driving LSC formation and maintenance, and how this compares to the epigenetic regulation of normal hematopoietic stem cells (HSCs).

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
The cAMP responsive element binding protein (CREB) pathway has been involved in two major cascades of gene expression regulating neuronal function. The first one presents CREB as a critical component of the molecular switch that control longlasting forms of neuronal plasticity and learning. The second one relates CREB to neuronal survival and protection. To investigate the role of CREB-dependent gene expression in neuronal plasticity and survival in vivo, we generated bitransgenic mice expressing A-CREB, an artificial peptide with strong and broad inhibitory effect on the CREB family, in forebrain neurons in a regulatable manner. The expression of ACREB in hippocampal neurons impaired L-LTP, reduced intrinsic excitability and the susceptibility to induced seizures, and altered both basal and activity-driven gene expression. In the long-term, the chronic inhibition of CREB function caused severe loss of neurons in the CA1 subfield as well as in other brain regions. Our experiments confirmed previous findings in CREB deficient mutants and revealed new aspects of CREB-dependent gene expression in the hippocampus supporting a dual role for CREB-dependent gene expression regulating intrinsic and synaptic plasticity and promoting neuronal survival. manufacturer's protocol.
