(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) Chinese Hamster Ovary cell lines are currently the primary host for production of therapeutic glycoproteins. Fast process development resulting in robust and scalable processes is a critical success factor in the highly competitive market for biosimilars. In process development screening of hundreds of clones and selection of process conditions are routinely performed in uncontrolled cultivation systems like shake flasks. more...

(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) Background: Chinese hamster ovary (CHO) cells are the most widely used mammalian host for recombinant protein production. The primary production method is to construct stable, high-yielding cell lines to provide high-quality, low-cost products. The key to optimizing recombinant protein production is to modify engineered cell lines to obtain better growth, expression, or product quality characteristics. more...

(Submitter supplied) Hexokinase catalyzes the first committed step in glucose metabolism by phosphorylating glucose to produce glucose-6-phosphate. Highly glycolytic proliferating cells such as cancer cells take advantage of HK2 expression to accelerate glucose metabolism even in the presence of oxygen. This acceleration not only provides sufficient glycolytic intermediates to support the anabolic demands of the cells but also inevitably accompanies increased formation of metabolic end products such as lactate. 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...

MicroRNAs (miRNAs) play crucial regulatory roles in the cancer development. However, the role of miRNAs in OSCC development and progression is not well understood.

(Submitter supplied) Diphthamide (DPH) is a conserved amino acid modification on eukaryotic translation elongation factor eEF2. We show that loss of DPH increases -1 ribosomal frameshifting at both programmed, including in SARS-CoV-2, and non-programmed sites. Ribosome profiling of yeast and mammalian cells lacking DPH reveals increased ribosomal drop-off during elongation. The drop-off defect on the long yeast MDN1 gene was suppressed by eliminating out-of-frame stop codons. more...

(Submitter supplied) Genes, principal units of genetic information, vary in complexity and evolutionary history. Less-complex genes (e.g. long non-coding RNA (lncRNA) expressing genes), readily emerge de novo from non-genic sequences and have high evolutionary turnover. Genesis of a gene is facilitated by adoption of functional genic sequences from retrotransposon insertions. However, protein-coding sequences in extant genomes rarely lack any connection to an ancestral protein-coding sequence. more...
