TLDR
The ways in which S1P might be therapeutically targeted are discussed — for example, via the development of chemical inhibitors that target the generation, transport and degradation of S 1P and via thedevelopment of specific S1p receptor agonists.Abstract:
The bioactive lipid sphingosine-1-phosphate (S1P) is involved in multiple cellular signalling systems and has a pivotal role in the control of immune cell trafficking. As such, S1P has been implicated in disorders such as cancer and inflammatory diseases. This Review discusses the ways in which S1P might be therapeutically targeted — for example, via the development of chemical inhibitors that target the generation, transport and degradation of S1P and via the development of specific S1P receptor agonists. We also highlight recent conflicting results observed in preclinical studies targeting S1P and discuss ongoing clinical trials in this field.read more

A comparative LC-MS based profiling approach to analyze lipid composition in tissue culture systems.
TL;DR: This method describes the isolation of lipids from tissue culture cells, sample preparation for LC-MS, theLC-MS run, and the subsequent data processing steps to compare the global lipid profiles and identify species that are enhanced or depleted.

STATs in cancer inflammation and immunity: a leading role for STAT3
TL;DR: Signal transducer and activator of transcription proteins are central in determining whether immune responses in the tumour microenvironment promote or inhibit cancer, and STAT3 is a promising target to redirect inflammation for cancer therapy.

Principles of bioactive lipid signalling: lessons from sphingolipids
TL;DR: An understanding of the complex pathways of sphingolipid metabolism and the mechanisms that regulate lipid generation and lipid action is required to understand the mechanisms of cell growth, death, senescence, adhesion, migration, inflammation, angiogenesis and intracellular trafficking.
