(Submitter supplied) Little is known about the global transcriptional program underlying megakaryocytic (Mk) differentiation, maturation, and apoptosis. Using DNA microarrays and Q-RT-PCR, we examined the transcriptional profile of Mk differentiation human CD34-positive hematopoietic stem and progenitor cells cultured with thrombopoietin, interleukin-3, and Flt3-ligand. The goal this study was to identify genes involved in the various facets of Mk differentiation including commitment, polyploidization, proplatelet formation, and apoptosis. more...

(Submitter supplied) Little is known about the global transcriptional program underlying megakaryocytic (Mk) differentiation, maturation, and apoptosis. Using DNA microarrays and Q-RT-PCR, we examined the transcriptional profile of phorbol-ester-induced Mk differentiation of the megakaryoblastic CHRF-288-11 (CHRF) cell line – a model system for investigating megakaryopoiesis. The goals of this study were to (1) verify the megakaryocytic nature of the CHRF cell line at the transcriptional level, and (2) extract novel insights into the key facets of Mk maturation including polyploidization, proplatelet formation, and apoptosis. more...

(Submitter supplied) d-serine is naturally present throughout the human body. It is also used as add-on therapy for treatment-refractory schizophrenia. d-Serine interacts with the strychnine-insensitive glycine binding site of NMDA receptor, and this interaction could lead to potentially toxic activity (i.e., excitotoxicity) in brain tissue. The transcriptomic changes that occur in the brain after d-serine exposure have not been fully explored. more...

(Submitter supplied) The alkylating agent N-methyl-N’-nitro-N-nitrosoguanidine (MNNG) induces cellular DNA damages and other comprehensive alterations that lead to chromosomal aberrations, mutations, tumor initiations, and cell death. However, the molecular mechanism of MNNG-induced cellular stress remains unclear.We have genome-wide analyzed early transcriptional responses of human FL amnion epithelial cells after exposure to three relatively low doses of MNNG (0.2, 1.0, and 10.0µM),and differential gene expression profiles were obtained 4 h after exposure using oligonucleotide microarrays followed by validation with quantitative real-time RT-PCR. more...

(Submitter supplied) Androgen-induced bZIP (AIbZIP) is a basic leucine zipper (bZIP) transcription factor that is encoded by the CREB3L4 (cAMP responsive element binding protein 3-like 4) gene. In humans, AIbZIP mRNA is most abundant in the prostate but it is also present, albeit at much lower levels, in the pancreas and other tissues. The full-length AIbZIP protein localizes to the endoplasmic reticulum and the available data suggest that AIbZIP is processed to its transcriptionally active form by regulated intramembrane proteolysis (RIP). more...

(Submitter supplied) This series of microarray experiments monitored the gene expression profiles for monoclonal cell lines (derived from HEK-293 parental cell culture) with high (H1, H15, H24, H36, H39) or low (L3, L28, L29) levels of store-operated Ca2+ entry (SOCE). For selection of clones, HEK-293 cells were loaded with indo-1 and sorted by FACS on the basis of their cyclopiazonic acid (CPA)-stimulated Ca2+ entry. Monoclonal cell lines were selected from the sorted cells and their levels of SOCE confirmed by monitoring thapsigargin-stimulated Ba2+ entry. more...

(Submitter supplied) Rationale: Immortalized cells may exhibit important differences relative to their primary cell counterparts. Microarrays were used compare primary human umbilical vein endothelial cells (HUVECs) and the immortalized HUVEC cell line EA.hy926, in their response to inhibition of the mevalonate pathway by a HMG-CoA reductase inhibitor (atorvastatin). The effects of atorvastatin were reversed by the addition of mevalonate, to subtract non-specific changes in gene expression. more...

(Submitter supplied) Clinical variability in sickle cell disease (SCD) suggests a role for extra-erythrocytic factors in the pathogenesis of vasoocclusion. We hypothesized that one potential factor, endothelial dysfunction, results from induction of phenotypic changes by circulating factors in SCD patients. The database reports gene expression in cultured human pulmonary artery endothelial cells (HPAEC) exposed to plasma from: a) sickle acute chest syndrome (ACS) patients (samples ; b) SCD patients at steady-state and c) normal volunteers using microarrays (U133A-B GeneChip Affymetrix). more...
