Fish n Chips: EcoArray to Design Minnow Chip for EPA

NEW YORK, Nov. 17 (GenomeWeb News) - EcoArray will develop a fish array to help the US Environmental Protection Agency perform environmental testing, the Alachua, Fla.-based company said yesterday.


Under a Cooperative Research and Development Agreement with the EPA, EcoArray will collaborate with EPA researchers in Ohioand Minnesotato design a gene chip for the fathead minnow, which the EPA uses to test the quality of freshwater. Chemicals in polluted water cause changes in gene expression in the fish, and the pattern of expression can indicate which chemical sare affecting the fish.


The purpose of the CRADA is to determine the best platform to use to construct a standard microarray for the fish. Once the platform is established, EcoArray plans to release microarrays for several species used in environmental analysis, the company said.

LINE-1 Linked to Premature Aging Conditions

Researchers report in Science Translational Medicine that the accumulation of LINE-1 RNA contributes to premature aging conditions and that symptoms can be improved by targeting them.

Team Presents Cattle Genotype-Tissue Expression Atlas

Using RNA sequences representing thousands of cattle samples, researchers looked at relationships between cattle genotype and tissue expression in Nature Genetics.

Researchers Map Recombination in Khoe-San Population

With whole-genome sequences for dozens of individuals from the Nama population, researchers saw in Genome Biology fine-scale recombination patterns that clustered outside of other populations.

Myotonic Dystrophy Repeat Detected in Family Genome Sequencing Analysis

While sequencing individuals from a multi-generation family, researchers identified a myotonic dystrophy type 2-related short tandem repeat in the European Journal of Human Genetics.
