MetabolomicsComparative LC/MS-based profiling of L-arginine producing, canavanine resistant Corynebacterium glutamicum strain ATCC 21831 and type strain ATCC 13032
Corynebacterium glutamicum strain ATCC 21831 is a producer of L-arginine that was created by random mutagenesis. It is resistant to the arginine structural analogue canavanine. In order to identify potential bottlenecks in the biosynthetic pathway that leads to this industrially important amino acid...

MetabolomicsCyclooxygenase-2, Asymmetric Dimethylarginine, and the Cardiovascular Hazard From Nonsteroidal Anti-Inflammatory Drugs (Murine and human plasma quantitative L-arginine and methylarginines UPLC-MS/MS assay)

BACKGROUND: Large-scale, placebo-controlled trials established that nonsteroidal anti-inflammatory drugs confer a cardiovascular hazard: this has been attributed to depression of cardioprotective products of cyclooxygenase (COX)-2, especially prostacyclin. An alternative mechanis...

MetabolomicsL-leucine increases the sensitivity of drug-resistant Salmonella to sarafloxacin by stimulating central carbon metabolism and increasing intracellular reactive oxygen species level (LC-MS positive mode)

The overuse of antibiotics has made public health and safety face a serious crisis. It is urgent to develop new clinical treatment methods to combat drug-resistant bacteria to alleviate the health crisis. The efficiency of antibiotics is closely related to the metabolic state of bacteria. However...

MetabolomicsL-leucine increases the sensitivity of drug-resistant Salmonella to sarafloxacin by stimulating central carbon metabolism and increasing intracellular reactive oxygen species level (LC-MS negative mode)

The overuse of antibiotics has made public health and safety face a serious crisis. It is urgent to develop new clinical treatment methods to combat drug-resistant bacteria to alleviate the health crisis. The efficiency of antibiotics is closely related to the metabolic state of bacteria. However...

TranscriptomicsL-Glutamine metabolism and its regulation in C. glutamicum
Corynebacterium glutamicum, a gram-positive soil bacterium used for the industrial production of amino acids such as L-glutamate and L-lysine, is able to use a number of different nitrogen sources, such as ammonium, urea, or creatinine. In this communication, we show that L-glutamine serves as an ex...

TranscriptomicsGene expression level during L-threonine production
The comparative transcriptome profiling of L-threonine producing strain (TH07 strain harboring pBRThrABC) and control W3110 (lacI-deleted) strain harboring pKK223-3 has been analyzed using oligo nucleotide microarray. Keywords: comparative transcriptome analysis (between L-threonine producing strai...

TranscriptomicsCombinatorial role of two paralogous splicing factors, hnRNP L and L-like, in multiple-exon regulation of CD45 alternative splicing
The goal of this study was to investigate the role of hnRNP L-like in alternative pre-mRNA splicing in human B-cells through an RNA-Seq approach. RNA-Seq was performed in DG75 cell line with over expression of hnRNP L-like or GFP as control.

GenomicsLRH-1 and PTF1-L coregulate an exocrine pancreas-specific transcriptional network for digestive function [ChIP-Seq]
We have determined the cistrome and transcriptome for the nuclear receptor liver receptor homolog-1 (LRH-1) in the exocrine pancreas. Chromatin immunoprecipitation (ChIP)-seq and RNA-seq analyses reveal that LRH-1 directly induces expression of genes encoding digestive enzymes and secretory and mit...

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...
