Project description:Recently, omics techniques have been widely applied to the discovery of potential bio-markers and explore triggering mechanism. To get a more comprehensive diagnosis of HBCD impacts on marine medaka (Oryzias melastigma), the larvae (within 24 hours post-hatch) were exposed to gradient doses of HBCD. After exposure for 7 days, the profiles of genes expression were examined using a custom-commercial 26, 430-oligonucleotide arrays (4×44K) of Japanese medaka which is shared much genomic information with marine medaka.At the end of the treatment period, 30 larvae/sample were pooled for RNA extraction and labeled by One-Color. A total of twelve independent arrays: three control (DMSO), three low-concentration HBCD (0.2 nM) exposures, three medium-concentration HBCD (2 nM) exposures, and three high-concentration HBCD (20 nM) exposures.

Project description:Recently, omics techniques have been widely applied to the discovery of potential bio-markers and explore triggering mechanism. To get a more comprehensive diagnosis of HBCD impacts on marine medaka (Oryzias melastigma), the larvae (within 24 hours post-hatch) were exposed to gradient doses of HBCD. After exposure for 7 days, the profiles of genes expression were examined using a custom-commercial 26, 430-oligonucleotide arrays (4M-CM-^W44K) of Japanese medaka which is shared much genomic information with marine medaka.At the end of the treatment period, 30 larvae/sample were pooled for RNA extraction and labeled by One-Color. A total of twelve independent arrays: three control (DMSO), three low-concentration HBCD (0.2 nM) exposures, three medium-concentration HBCD (2 nM) exposures, and three high-concentration HBCD (20 nM) exposures. The larvae of marine medaka (within 24 hours post-hatch) were exposed to to 0 (control), 0.2nM, 2nM and 20nM of HBCD (dimethyl sulfoxide with a final concentration of 1:30000 v/v water) for 7 days. Each HBCD treatment had three replicates with 100 larvae for each Petri dish. At the end of the treatment period, 30 larvae/sample were pooled for RNA extraction. A total of twelve independent arrays: three control (DMSO), three low-concentration HBCD (0.2 nM) exposures, three medium-concentration HBCD (2 nM) exposures, and three high-concentration HBCD (20 nM) exposures.
Project description:We employed a transgenic strain of a small aquarium fish medaka (Oryzias latipes) that overexpresses a malignant melanoma driver gene. In this model, melanoma develops with 100 % penetrance. Using the medaka malignant melanoma model, we tested whether cisplatin and trametinib are able to suppress the transcriptomic changes induced by the transgene.

Project description:Testis transcriptome of marine medaka (Oryzias melastigma) upon exposure to microplastics
Project description:To elucidate molecular mechanisms contributing to the disease phenotype in col10a1 medaka (Oryzias latipes) mutants, we isolated col10a1:nlGFP cells from heterozygous col10a1 medaka mutants and wild-type siblings via fluorescence activated cell sorting (FACS) and performed RNA-seq. Comparison of the transcriptome profiles indicated elevated ER stress, dysregulated cell polarity and reduced ECM production in heterozygous col10a1 mutants.
