CHO Epigenomic Data

April 14, 2016

A new database of epigenomic information ( for 6 CHO cell lines has been created by Dr. Nicole Borth's group. A link to this database has been added to'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 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 databases. The complete list of these genes can be found on the Data tab in the CHO Community Files & Links section.


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.
