News

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 https://chomine.boku.ac.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 Matthias.Gerstl@acib.at or Nicole.Borth@boku.ac.at.

CHO Epigenomic Data

April 14, 2016

A new database of epigenomic information (cho-epigenome.boku.ac.at) for 6 CHO cell lines has been created by Dr. Nicole Borth's group. A link to this database has been added to CHOgenome.org's Data webpage. The epigenomic database website hosts genome sequences for 6 cell lines, SNPs, structural variants, full genome methylation data, and batch culture histone modification data. The manuscript describing the acquisition and analysis of the data can be found here.

Gene Names with Prime Notation

June 24, 2015

Within the 2014 RefSeq annotations, 211 genes were recently identified as having not been loaded in the CHOgenome.org databases due to coding algorithm errors caused by prime notation (e.g. - 3' or 5') in the gene's name and product description. These errors have been rectified and the 211 genes, 115 genes in the 2014 CHO-K1 annotation and 96 genes in the 2014 CH annotation, have been correctly loaded to their respective CHOgenome.org databases. The complete list of these genes can be found on the Data tab in the CHO Community Files & Links section.

Update:

May 29, 2015

A featured article section has been added to the homepage, where articles of potential interest to the CHO community will be posted periodically. The current and past featured articles will be archived in the new "Featured Articles" page which can be accessed through the Resources tab.

Genome Viewer Upgrades

April 20, 2015

The 2012 tracks have been added to the CHO-K1 JBrowse genome viewer tool. In addition, the 2014 Chinese hamster RefSeq browser has been created with annotation tracks. A new portal page provides access to these browsers by selecting the Genome Viewer tab or button. Also, new links are available in the RefSeq gene details page that link directly to the appropriate JBrowse viewer and scaffold.

BLAST and File Archive Upgrade

March 20, 2015

The BLAST and File Archive tools have been successfully updated. If you experience any issues, please let us know.

CHOStart March Update

March 2, 2015

The CHOStart project has generated 170 SMRT cells and 95 GB of genomic sequence data so far. Thanks to your support, we have raised ~40% of the fundraising goal.

details

CHOStart December Update

December 19, 2014

The CHOStart project has generated 84 SMRT cells and 42 GB of genomic sequence data so far. Thanks to your support, we have raised ~30% of the fundraising goal. More details and updates regarding the CHOStart project can be found here.

Update:

October 23, 2014

The genome viewer tutorial has been updated with the instructions on how to use JBrowse. The tutorials can be found under the "General Info" tab. Another JBrowse instance has been added as well, which contains the nucleotide sequence of the Chinese Hamster chromosomes (from Brinkrolf K et al).

Update:

October 9, 2014

The CHO-K1 genome viewer has been updated from GBrowse to JBrowse, and contains the most up to date annotations (from 2014). The GBrowse instance for the 2012 annotated version of CHO-K1 is still available in the legacy version of the website (linked at the bottom of this page). The updated tutorial for viewing the genomes in JBrowse will be posted shortly.

We're getting a facelift in the near future!

August 28, 2014

The updates will provide a more organized approach to searching the data and going through results - especially important given the recent release of new genomes. Don't worry: all of the legacy genomes (CHO-K1 GenBank, and earlier CHO-K1 RefSeq) will be maintained on the website and will still be searchable. In fact, we will keep legacy pages operational for the foreseeable future in case you like the current look and feel.

As always, please let us know of any unusual or unexpected issues and to share your feedback on the new look and feel.

Update:

June 27, 2014

The BLAST server will periodically be unavailable for the next few days to permit updates to be made.

A crowdfunding request for PacBio hamster sequencing

May 29, 2014

The community plans to collect third generation sequencing data (PacBio) on the hamster to help create a new reference assembly. We expect the effort to cost $60,000. We request support from the community. The suggested support level is $5000 per organization, although amounts larger and smaller are welcome. Contributions from U.S. organizations are tax deductible. Our timeline is to collect all data by end of 2014 and to manually correct automated annotations through 2015. Any funds collected over our $60,000 target will support the annotation effort.
Goal: $60,000
Current Commitments: $20,000

The international community's effort was recognized as a finalist at the 2012 Bioprocess International Awards ceremony in Providence, RI. Our efforts were nominated as part of the Upstream Collaboration of the Decade. According to the BPI website:
"The Collaboration of the Decade Award recognizes industry alliances and collaborations whose innovative partnerships dramatically transformed stand-alone technologies. These collaborations result in overall process cost reduction while creating new, effective approaches to biopharmaceutical design, development, and manufacturing."

We are grateful for the support and engagement of the broad international community in sequencing of CHO and related genomes to improve bioprocessing.
