New mRNA Expression Browser (Beta)

June 7, 2017

The browser (beta version) for the visualization of mRNA expression from CHO-K1 cells is now online. The data is from several published DNA-microarray or RNA-Seq experiments. The tutorial on how to use this browser can be found here.

Coming Soon!

March 10, 2017

Users will be able to visualize CHO cell mRNA expression data either from published DNA-microarray or RNA-Seq experiments via JBrowse. The visualized data will enable users to easily obtain gene expression levels and compare gene expression levels among different conditions.

CHOmine (BETA-Version)

August 19, 2016

CHOmine, the InterMine site for CHO and Chinese hamster, went online on August 11, 2016 at CHOmine collects and integrates publicly available Chinese hamster and CHO data, where different datasets are connected to provide user-friendly access. Currently, users are asked to test the site and to provide feedback (impressions, comments, issues, and suggestions for improvements) to or

Symbol CHO-K1 (RefSeq Assembly GCF_000223151.1 | 2May2014 - Release 101)
Gene Name Chinese Hamster (RefSeq Assembly GCF_000419365.1 | 2May2014 - Release 101)

The CHO-K1 RefSeq database can be searched by:

  1. Gene name (i.e. Caspase 1)
  2. Gene symbol (i.e. Casp1)
  3. Gene ID (i.e. 100759171)

BLAST the CHO-K1 RefSeq and Chinese Hamster RefSeq genomes here and at NCBI.

Tips for using the database:

  1. Search by gene name, symbol, or ID to find individual gene pages.
  2. Multiple genomes may be selected at once, but the time required for the query may increase.
  3. Each gene, transcript, and protein has a unique, individual entry. To obtain the relevant protein information or download the protein sequence, select the gene or transcript entry of interest, scroll to the bottom of the "Gene Details" page, and select the protein entry associated with the relevant transcript in the "Gene Relations" table.
  4. Many pseudogenes do not have a gene name or symbol, but all have a gene ID and may be searched.
