The totality of environmental exposures and lifestyle factors, commonly referred to as the exposome, are poorly understood. Measuring the myriad of chemicals that humans are exposed to is immensely challenging and identifying disrupted metabolic pathways is even more complex. Here, we present a n...

Non-target analysis based on high resolution mass spectrometry calls for quality controls to validate analytical workflows. So far no community-wide used quality control material has been established in metabolomics. In this work, we propose ethanolic yeast extracts derived from Pichia pastoris i...

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...
