TLDR
Novel analytical approaches — in particular, liquid chromatography and mass spectrometry — for systems-level analysis of lipids and their interacting partners (lipidomics) now make this field a promising area of biomedical research, with a variety of applications in drug and biomarker development.
Abstract
The crucial role of lipids in cell, tissue and organ physiology is demonstrated by a large number of genetic studies and by many human diseases that involve the disruption of lipid metabolic enzymes and pathways. Examples of such diseases include cancer, diabetes, as well as neurodegenerative and infectious diseases. So far, the explosion of information in the fields of genomics and proteomics has not been matched by a corresponding advancement of knowledge in the field of lipids, which is largely due to the complexity of lipids and the lack of powerful tools for their analysis. Novel analytical approaches--in particular, liquid chromatography and mass spectrometry--for systems-level analysis of lipids and their interacting partners (lipidomics) now make this field a promising area of biomedical research, with a variety of applications in drug and biomarker development.

Lipid extraction by methyl-tert-butyl ether for high-throughput lipidomics

TL;DR: In this paper, the methyl-tert-butyl ether (MTBE) extraction method was used for shotgun profiling of lipid species, and the results showed that the MTBE protocol delivered similar or better recoveries of species of most major lipid classes compared with the "gold-standard" Folch or Bligh and Dyer recipes.

Global analysis of the yeast lipidome by quantitative shotgun mass spectrometry

TL;DR: Comparative lipidomics demonstrated that growth temperature and defects in lipid biosynthesis induce ripple effects throughout the molecular composition of the yeast lipidome, establishing shotgun lipidomics as a powerful platform for complementing biochemical studies and other systems-level approaches.

ABC transporters in cancer: more than just drug efflux pumps.

TL;DR: It is proposed that delineating the precise roles of these transporters in tumorigenesis and treatment response will be important for the development of more effective targeted therapies.

The model organism as a system: integrating 'omics' data sets.

TL;DR: Researchers are rising to the challenge by using omics data integration to address fundamental biological questions that would increase the understanding of systems as a whole.

Quantitative analysis of biological membrane lipids at the low picomole level by nano-electrospray ionization tandem mass spectrometry.

TL;DR: The optimized ionization and fragmentation conditions described together with the principle of internal standardization by nonnatural analogues allow the rapid and quantitative determination of membrane lipid compositions down to sample amounts of 1000 cells.

Electrospray mass spectrometry of phospholipids

TL;DR: The current level of understanding of the mechanisms involved in the formation of various product ions following collisional activation of molecular ion species generated by electrospray ionization of the common glycerophospholipids is presented.

Cell biology of protein misfolding: The examples of Alzheimer's and Parkinson's diseases

TL;DR: The salutary intersection of fundamental cell biology with the study of disease is well illustrated by the emerging elucidation of neurodegenerative disorders, where normally-soluble proteins accumulate, misfold and oligomerize, inducing cytotoxic effects that are particularly devastating in the post-mitotic milieu of the neuron.

Role for Stearoyl-CoA Desaturase-1 in Leptin-Mediated Weight Loss

TL;DR: Ob/ob mice with mutations in SCD-1 were significantly less obese than ob/ob controls and had markedly increased energy expenditure, suggesting that down-regulation of SCD1 is an important component of leptin's metabolic actions.

CD36 is a sensor of diacylglycerides

TL;DR: It is shown that an N-ethyl-N-nitrosourea-induced nonsense mutation of Cd36 causes a recessive immunodeficiency phenotype in which macrophages are insensitive to the R-enantiomer of MALP-2 (a diacylated bacterial lipopeptide) and to lipoteichoic acid.
