(Submitter supplied) Hypoxia is amongst the most widespread and pressing problems in aquatic environments. For the first time, we demonstrate that fish (Oryzias melastigma) exposed to hypoxia show reproductive impairments in F2 generations despite these progenies (and their germ cells) having never been exposed to hypoxia. We further show that the observed transgenerational reproductive impairments are associated with a differential methylation pattern of specific genes in sperm of both F0 and F2.

(Submitter supplied) We performed miRNA transcriptome analysis of mature medaka tissues using high-throughput next generation sequencing technology. The small RNA libraries were contructed from brain, liver and gonads in mature male and female medaka and a total of more than 128 million sequencing reads were generated from the six small RNA libraries. By comparison to known miRNA database, a total of 223 known miRNA types were identified with more than 50% expressed in brain. more...

(Submitter supplied) 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. more...
