MetabolomicsAn LC–MS-based lipidomics pre-processing framework underpins rapid hypothesis generation towards CHO systems biotechnology

INTRODUCTION: Given a raw LC–MS dataset, it is often required to rapidly generate initial hypotheses, in conjunction with other ‘omics’ datasets, without time-consuming lipid verifications. Furthermore, for meta-analysis of many datasets, it may be impractical to conduct exhausti...

MetabolomicsMechanistic insights into the biological activity of S-Sulfocysteine in CHO cells using a multi-omics approach
S-Sulfocysteine (SSC), a bioavailable L-cysteine derivative (Cys), is known to be taken up and metabolized in Chinese hamster ovary (CHO) cells used to produce novel therapeutic biological entities. To gain a deeper mechanistic insight into the SSC biological activity and metabolization, a multi-omi...

MetabolomicsWhat CHO is made of: Variations in the biomass composition of Chinese hamster ovary cell lines

Background: Cell line specific, genome-scale metabolic models enable rigorous and systematic in silico investigation of cellular metabolism. Such models have recently become available for Chinese hamster ovary (CHO) too. However, a key ingredient, namely an experimentally validat...

TranscriptomicsCHO smallRNA sequencing for microRNA annotation
MicroRNAs are small non-coding RNAs that play a critical role in post-transcriptional control of gene expression. Recent publications of genomic sequencing data from CHO cells provide new tools for the discovery of novel miRNAs in this important production system. The current release of the miRNA re...

TranscriptomicsCHO cells with enhanced and abolished gamma-secretase activity
γ-secretase is an intra-membrane-cleaving aspartyl protease implicated in the processing of a wide range of type I membrane proteins including the Notch receptor and the amyloid-β precursor protein (APP). It thus regulates a diverse array of cellular and biological processes including the differen...

MetabolomicsOral ketone monoester ingestion reduces circulating blood glucose, exogenous carbohydrate oxidation and oxidation efficiency in trained male cyclists when fed 120 g of CHO per hour during exercise

We examined the effects of ketone monoester (KME) and carbohydrate (CHO) co-ingestion on exogenous CHO oxidation, metabolomic responses and exercise capacity. In a randomised repeated-measures design (after a 36 h CHO loading protocol and pre-exercise meal of 12 and 2 g.kg-1, respectively), eight...

TranscriptomicsRevealing suspension adapation of CHO cell in serum free media
Purpose : We performed strand-specific RNA-seq analysis of CHO cells according to adaptation trajectory to identify the specific genes responded to the suspension adaptation. Result : Cell growth, replication, and nucleotide metabolism categories were enriched in up regulated clusters whereas cellul...

TranscriptomicsGene Expression in the Human Mammary Epithelium in response to consumption of high fat (H-FAT) and high carbohdyrate (H-CHO) diets.
Mammary gland (MG) de novo lipogenesis contributes significantly to milk fat in animals but little is known in humans. We hypothesized that de novo lipogenesis, as reflected by incorporation of 13C carbons from [U-13C]glucose into fatty acids (FAs) and glycerol in triglycerides (TG), will be greate...

TranscriptomicsAnalysis of mature miRNA levels in the context of CHO cell proliferation
mature microRNA transcripts were analyzed in 5 CHO cell lines growing at different proliferation rates. The goal was to identify microRNAs that correlate positively or negatively with CHO proliferation rates. A common reference design was chosen, where all samples were hybridized against a pool of a...

TranscriptomicsProfiling miRNAs of high, low and non-producing CHO cells during biphasic Fed-Batch cultivations reveal interesting targets for cell line engineering
Fed-batch cultivation of recombinant Chinese hamster ovary (CHO) cell lines is one of the most widely used production mode for commercial manufacturing of recombinant protein therapeutics. Furthermore, fed-batch cultivations are often conducted as biphasic processes where culture temperature is decr...
