Project description:The aim of the study was to investigate whether the trefoil peptide genes, in concerted action with a miRNA regulatory network, were contributing to nutritional maintrenance. Using a Tff3 knock-out mouse model, 21 specific miRNAs were noted to be significantly deregulated when compared to the wild type strain. n = 6 mus musculus wild type samples and n = 6 knock-down experiments have been screened for a currently known mus musculus miRNAs and validated by TaqMan

Project description:We explored the role of FOG-1 in GATA-1 transcriptional regulation of megakaryocyte differentiation through expression of wild-type GATA-1 and the FOG-binding mutant of GATA-1 (GATA-1^V205G) in G1ME cells.
Project description:Hematopoietic progenitor cells were isolated from 13.5 day mouse fetal livers by lineage depletion and expanded for three days. Fetal livers were isolated from both wild type and Gata-1 knock embryos. Gata-1 knock embryos contain a deletion of the Gata-1 promoter sequence that results in undetectable levels of Gata-1 protein specifically in the megakaryocyte lineage. Following progenitor outgrowth megakaryocytes were enriched in a differentiation media for three days and isolated on a discontinuous BSA gradient. The resulting megakaryocytes were >90% pure as determined by acetylcholinesterase staining. These cells were lysed in Trizol and the resulting RNA was used for hybridization.

Project description:We explored the role of FOG-1 in GATA-1 transcriptional regulation of megakaryocyte differentiation through expression of wild-type GATA-1 and the FOG-binding mutant of GATA-1 (GATA-1^V205G) in G1ME cells. G1ME cells were derived from Gata1-null mouse ES cells and have both megakaryocyte and erythrocyte differentiation potential upon reconstitution of GATA-1 expression (Stachura 2006). HA-tagged wild-type or mutant GATA-1 were expressed in G1ME cells grown in TPO via retroviral transductions. The cells were sorted for GFP positivity 68 hours post-transduction and then were allowed to recover in normal growth medium for 4h. Total RNA was then isolated using RNeasy kit from Qiagen 72 hours post-transduction.
