Transcription profiling by array of rat cerebellar granular neuronal precursor cells plated with Sonic Hedgehog (Shh) and then treated with the PKA activator DBA
Ontology highlight
ABSTRACT: Cerebellar granular neuronal precursors were plated in presence of Sonic Hedgehog (Shh) for 24h and then treated with the PKA activator Dibutyryl Cyclic Adenosine Monophosphate (DBA) for addittional 24h
Project description:Proliferating cerebellar granular cells were cultured in presence of Shh for 24h (3ug/ml) and then pulsed for additional 24h with Bmp2 or vehicle. Cells then were lysed and mRNA extracted. Microarray data from cells treated with Bmp2 was referred to the control not treated with Bmp2.
Project description:During exocytosis, a Ca2+ increase arises in close vicinity of secretory granules which is strictly prevented in resting cells. Granular Ca2+ homeostasis and its role in granular exocytosis are not well understood.
Project description:A neuronal PI(3,4,5)P3-dependent program of oligodendrocyte precursor recruitment and myelination was identified in mice that conditionally lack PTEN in cerebellar granular cells (PTEN cKO) Expression analysis was performed with RNA obtained selectively from cerebellar granular cell layer of PTEN conditional null mutants and controls
Project description:The bone marrow microenvironment in Large Granular Lymphocyte Leukemia (LGLL) patients has been unexplored for it’s role in the development of cytopenias, which lead to complications resulting in the most prominent causes of morbidity and mortality. We used microarrays on primary mesenchymal stem cell (MSC) cultures isolated from bone marrow aspirates from LGLL patients to identify genetic programs that may lead to the observed profibrotic and extrinsically senescent phenotype.
Project description:Large granular lymphocyte leukemia (LGLL) is a rare lymphoproliferative malignancy caused by clonal expansion of granular lymphocytes. Two subgroups, (cytotoxic) T-cell LGLL and natural killer (NK) cell LGLL, are defined based on their cellular origin and expression of characteristic surface molecules. In this study, we performed a comparative proteome profiling of isolated extracellular vesicles (EV) from the T-LGLL cell line MOTN-1 and the NK-LGLL line NKL.
