(Submitter supplied) CHO cells are major hosts for the industrial production of therapeutic proteins and their production stability is of considerable economic significance. It is widely known that CHO cells can rapidly acquire genetic alterations, which affects their genetic homogeneity over time. However, the role of non-genetic mechanisms, including epigenetic mechanisms such as DNA methylation, remains poorly understood. more...

(Submitter supplied) In order to illustrate the epigenetic heterogeneity, versatile tools of single-cell ChIP-seq(scChIP-seq) are necessary to meet the convenience and accuracy. Here, we develop MobiChIP, a compatible ChIP-seq library construction method based current sequencing platform with single cell level. As a novel capture strategy, MobiChIP is efficient to capture the fragments from tagmented nuclei of numerous species and execute the mixing of samples from different tissues or species. more...

(Submitter supplied) CHO cells have primarily been studied in bulk, assuming that these bulk samples are identical because of genetic clonality across the sample. In this study, we performed single-cell RNA sequencing on two clonal CHO-K1 cell populations with different stability phenotypes over a 90 day culture period.

(Submitter supplied) Activating transcription factor 6 alpha (ATF6⍺) is one of the three endoplasmic reticulum (ER) transmembrane stress sensors that mediate the unfolded protein response (UPR). Despite its significant involvement in long-term ER stress adaption, regulation of ATF6⍺ signalling is still poorly understood, possibly because its activation involves Golgi and nucleus trafficking. Here, we have generated a dual CHO-K1 ATF6⍺/IRE1⍺ reporter cell line to perform an unbiased genome-wide CRISPR/Cas9 mutagenesis screen, in the presence and absence of ER stress, to systematically profile genetic factors that specifically contribute to ATF6⍺ signalling. more...

(Submitter supplied) We analyzed the transcriptomic response in three distinct CHO cell lines: a non-producing host cell line (CHOZN®GS-/-), an immunoglobulin G1 (IgG1) producer, and an erythropoietin Fc fusion (EPO-Fc) producer. We compared the growth and production characteristics of all three cell lines during fed-batch culture. High throughput RNA sequencing (RNASeq) and quantitative polymerase chain reaction (qPCR) were used to study differential gene expression analysis of the timecourse dataset with the host cell line CHOZN®GS-/- as the reference. more...

(Submitter supplied) We found piRNAs with different lengths represented the predominant small RNA species in oocytes from the 12 explored species, except mouse. We found endo-siRNAs resulted from the truncated Dicer isoform were mouse-specific, and os-piRNAs associating with PIWIL3 in human oocytes are widespread in mammals and are typically with low levels of the 2’-3’-O-methylation. The sequences of many highly expressed piRNA clusters are fast-evolving compared with their syntenic genomic locations, and the TE families distributing in the conserved piRNA clusters are various between species.

(Submitter supplied) Mammalian cells are critical hosts for the production of most therapeutic proteins and many proteins for biomedical research. While cell line engineering and bioprocess optimization have yielded high protein titers of some recombinant proteins, many proteins remain difficult to express. Here we use systems biology methods to deciper the factors influencing yields in Chinese hamster ovary (CHO) cells as they produce proteins from the human secretome.

(Submitter supplied) The Mammalian Methylation Consortium aimed to characterize the relationship between cytosine methylation levels and a) species characteristics such as maximum lifespan and b) individual sample characteristics such as age, sex, tissue type. Both supervised machine learning approaches and unsupervised machine learning approaches were applied to the data as described in the citations. To facilitate comparative analyses across species, the mammalian methylation consortium applied a single measurement platform (the mammalian methylation array, GPL28271) to n=15216 DNA samples derived from 70 tissue types of 348 different mammalian species (331 eutherian-, 15 marsupial-, and 2 monotreme species). more...

(Submitter supplied) A new area of focus in Chinese Hamster Ovary (CHO) biotechnology is the role of small (exosomes) and large (microvesicles or microparticles) extracellular vesicles (EVs). CHO cells in culture exchange large quantities of proteins and RNA through these EVs, yet the content and role of these EVs remain elusive. MicroRNAs (miRs) are central to adaptive responses to stress and more broadly to changes in culture conditions. more...
