Development of gene expression signatures after knocking down of miR-132 in zebrafish

ABSTRACT: To further development of the gene expression, we have employed whole genome microarray expression profiling as a discovery platform to identify genes that are regulated in miR-132 knockdown zebrafish. Zebrafish larvae were injected with Control MO or miR-132 MO at one-cell stage. Then the upregulated genes are combined to the miRNA prediction alagorithm. 21 genes were picked up and verifed by luciferase assay. The total RNA was extracted from 3 dpf zebrafish injected with 8 ng control or miR-132 MO MO. The RNA was applied for the microarray gene proliling

Transcription profiling of zebrafish embryos injected with a morpholino targeting LIN9

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.<br>

Ribosomal biogenesis genes play an essential and p53-independent role in pancreas development

Project description:Analysis of transcriptional profiles in Sbds(ATG) MO-injected embryos with and without coinjection of p53(ATG) MO. We identified a large number of changes in transcript abundance associated with loss of Sbds. Among the 24,278 annotated zebrafish genes in the platform, 4,892 significantly differentially expressed genes were identified. Embryos were carefully staged at 24 hpf and RNA was extracted from approximately 50 embryos per condition in Trizol, followed by purification using RNA miniprep columns (Qiagen). Four independent experiments were extracted. cDNA microarrays were performed at the Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins Microarray Core Facility using 4x44K Zebrafish gene expression microarray slides (Agilent, Santa Clara, CA).

MicroRNA-146 function in the innate immune response of zebrafish embryos to Salmonella typhimurium infection [miRNA profile]

Project description:This study reports on infection-inducible miRNAs in zebrafish. Using a custom-designed microarray platform for miRNA expression we found that miRNAs of the miR-21, miR-29, and miR-146 families were commonly induced by infection of zebrafish embryos with Salmonella typhimurium and by infection of adult fish with Mycobacterium marinum. A custom-designed Agilent zebrafish 8x15k miRNA platform was used to profile miRNA expression in zebrafish embryos infected with Salmonella typhimurium strain SL1027 and adult zebrafish infected with Mycobacterium marinum strain Mma20 . The 15k design contained a duplicate of 7604 probes of 60-oligonucleotide length. The probes consisted of 2x22 nucleotide sequences antisense to mature miRNAs separated by a spacer of 8 nucleotides (CGATCTTT) and with a second spacer with the same sequence at the end. From 7604 probes 546 were designed for left (5') and right (3') arms of the hairpins of zebrafish miRNAs known in miRBase, while the remainder 7058 probes corresponded to predicted hairpin structures in the zebrafish genome that might include additional miRNAs but were not considered in this study. Zebrafish embryos were infected at 28 hours post fertilization (hpf) by injecting 200-250 colony forming units of Salmonella typhimurium into the caudal vein and miRNA profiles of infected embryos were compared to control embryos injected with PBS (phosphate buffered saline) at 8 hours post-infection (hpi; 3 biological replicates and 2 technical replicates per each sample). Adult zebrafish were infected with 10000 colony forming units of Mycobacterium marinum and miRNA profiles were compared to PBS-injected control fish at 6 days post infection (dpi; 3 biological replicates). For dual color hybridization of the Agilent chips miRNA samples from infected zebrafish were labeled with Hy3 and samples from control fish were labeled with Hy5.
