Project description:TÜAB zebrafish were maintained at 28.5 °C in in 1x Danieau solution (58 mM NaCl, 0.7 mM KCl, 0.4 mM MgSO4, 0.6 mM Ca (NO3)2, 5 mM HEPES, pH 7.6, 0.0001 % Methylene blue). Morpholinos (Gene Tools, Philomath, OR) were designed against Danio rerio lin-9 homolog (Genebank accession NM_001044946). The morpholino (MO) sequences were MO-E1 5´-GTTAGTTTTATTACTCACTCTCGTC-3´ and 5-base mismatch morpholino MO-E1mis 5´-GTTACTTTTAATACTGACTGTCCTC-3´. 7 ng of morpholinos were injected into one cell-stage embryos. 20 embryos per condition (MO E1; MO E1mis) were pooled for RNA purification 24 h post fertilization. Using the two color Quick-Amp Labeling Kit (Agilent; 5190-0444) 100 ng of total RNA were used for cDNA synthesis, mRNA amplification and labeling according to manufacturers instructions. Transcriptional profiling was done on a zebrafish oligo array (Agilent; G2519F AMADID 019161) in a 4 x 44K slide format and analyzed as described before.

Transcription profiling of hind limbs from annexin A5 and A6 knock-out mice

Project description:Initiation of mineralisation during endochondral ossification is a multistep process and was assumed to correlate with specific interactions of annexins and collagens. Annexins A5 and A6 are postulated to represent the essential annexins promoting cartilage mineralisation. However, skeletal development appears to be normal in annexin A5 or A6 deficient mice. The highly conserved structures of annexins led to the assumption that annexins A5 and A6 may fulfill redundant functions. We now generated mice deficient for both proteins, annexins A5 and A6. Mice were viable, fertile and showed no obvious abnormalities. Assessment of skeletal elements using histological, ultrastructural and peripheral quantitative computed tomography methods revealed that mineralisation and development of the skeleton was not significantly affected in mutant mice. In respect of the lack of an obvious phenotype we now applied microarray analysis to the growth plate to define changes in the transcriptome of juvenile murine growth plates from mutant mice. Global gene expression analysis revealed subtle phenotypes at the transcriptome level of genes involved in cell growth and intermediate metabolism in mutant mice. These data demonstrate that both annexins are dispensable for proper cartilage mineralisation but may affect cell proliferation processes at the transcriptomic level.

Transcription profiling of mouse embyronic fibroblasts from wild type and Lin9 knockout strains treated with 4-hydroxytestosterone

Project description:We used microarrays to analyze the role of Lin9 in gene expression. Experimental overall design: We prepared MEFs from embyos containing a conditional allele of Lin9 and a CreERT2 transgene. Transcriptional profiles of untreated and 4-OHT-treated MEFs were compared.
