TPPP/p25, a recently identified tubulin polymerization-promoting protein (TPPP), is expressed mainly in myelinating oligodendrocytes of the CNS. Here, we show that TPPP/p25 is strongly upregulated during the differentiation of primary oligodendrocyte cells as well as the CG-4 cell line. The microRNA expression profile of CG-4 cells before and after induction of differentiation was established and revealed differential regulation of a limited subset of microRNAs. miR-206, a microRNA predicted to ...[more]
Project description:microRNA expression profiles in two stage-specific populations of oligodendrocytes: OPCs expressing the A2B5 ganglioside (A2B5+ cells) and OLs that are positive for the galactocerebroside marker (GalC+ cells). Cells were isolated postnatal day 7.
Project description:Comparison of females mated to males null for Sex-Peptide (SP0, Liu, H. and E. Kubli, Sex-peptide is the molecular basis of the sperm effect in Drosophila melanogaster. Proc Natl Acad Sci U S A, 2003. 100(17): p. 9929-33) or to control, Sex-Peptide producing, males. Comparisons were made at 3 and 6 hours after mating, in dissected Head - Thorax body parts.

Project description:Exploration of transcriptome expression in 5 control and 4 familial dysautonomia (FD) human olfactory ecto-mesenchymal stem cells (hOE-MSCs) at very early (P1 and P2) and later (P5 and P9) cell passages.
Project description:We decreased TAL1 and NKX3.1 proteins levels using lentiviral deliveries of shTAL1 and shNKX3.1 in TAL1 expressing human T-ALL cell lines. Growth curves of cell lines showed that reduced TAL1 and NKX3.1 expressions resulted in a first phase where the number of cells did not increase likewise the shCTL expressing cells. To identify TAL1 and NKX3.1 target genes involved in T-ALL cell growth, we performed gene expression profiling of cell lines expressing shTAL1, shNKX3.1 or shCTL after two and three days of culture. <br><br><br><br>
Project description:To study the composition of mRNPs containing TcDhh1, we carried out immunoprecipitation assays with anti-TcDhh1 and epimastigotes lysates. Pre-immune serum was used as control. We also carried out a ribonomic approach to identify the mRNAs present within the TcDhh1 immunoprecipitated complexes. For this purpose, competitive microarray hibridizations were performed against negative controls, the non-precipitated fraction.
