Project description:RNA-sequencing was performed on H1299, HEK293T and CHO-K1 transfected with plasmids expressing EGFP and mKate in an open loop circuit (OL), w/wo compound supplementation, or with iFFL circuit.mKate has target sites for miRNAs highly expressed in the different cell lines (miRNA31 for H1299, miRNA221 for HEK293T and miRNA21 for CHO-K1)
Project description: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.
Project description:Transcriptional profiling of CHO-K1 cells comparing to in-house serum-free and suspension adapted CHO-K1 cells in the exponential phase. Goal was to determine the effects of serum on CHO-K1 cells.
Project description:CHO-K1 (wildtype) and CHO-K6 (stablely overexpressing human HER2) cells were terated with 10 ug/ml transtuzumab or pertuzumab and their combination for 24 h and then the whole gene expression was analyzed by cDNA array.
Project description:In biopharmaceutical production, Chinese hamster ovary (CHO) cells derived from Cricetulus griseus remain the most commonly used host cell for recombinant protein production, especially antibodies. Over the last decade in-depth multi-omics characterization of these CHO cells provided data for extensive cell line engineering and corresponding increases in productivity. exosomes, extracellular vesicles containing proteins and nucleic acids, are barely researched at all in CHO cells. Exosomes have been proven to be an ubiquitous mediator of intercellular communication and are proposed as new biopharmaceutical format for drug delivery, indicator reflecting host cell condition and anti-apoptotic factor in spent media. Here we sequenced non-coding RNA of Exosomes (EXO) and whole cell lysate (WCL) isolated from CHO-K1 Cell Cultures at different growth phases (logarithmic/exponential phase (log/exp), stationary phase (stat), as well as death phase at 80 % viability (80 % ) and 60 % viability (60 %)) via Lexogen Small RNA-Seq Library Prep Kit for Illumina on the Illumina MiSeq platform in PE mode 2 x 36nt.
