Rapid tin-mediated access to a lysophosphatidylethanolamine (LPE) library: Application to positional LC/MS analysis for hepatic LPEs in non-alcoholic steatohepatitis model mice
摘要:
Even though lysophospholipids have attracted much interest in recent years on account of their unique bioactivity, research related to lysophospholipids is usually hampered by problems associated with standard sample preparation and discrimination of regioisomers. Herein, we demonstrate a quick tin chemistry-based synthetic route to lysophosphatidylethanolamines (LPEs) and its application in the positional analysis of hepatic LPEs in non-alcoholic steatohepatitis (NASH) model mice. We found that the preference of hepatic LPE regioisomer largely depends on the unsaturation of acyl chain in both control and NASH model mice. In addition, hepatic C18:2-LPE and C20:5-LPE levels were significantly lower in the NASH model mice than those in the control. The LC/MS technique based on the library of LPE regioisomers allows an accurate observation of hepatic LPE metabolism and might provide useful information to elucidate yet ambiguous pathogenesis of NASH.

The present invention describes a method for predicting a health-state indicative of the presence of prostate cancer. The method measures the intensities of specific small biochemicals, called metabolites, in a blood sample from a patient with an undetermined health-state, and compares these intensities to the intensities observed in a population of healthy individuals and/or to the intensities previously observed in a population of confirmed prostate cancer-positive individuals. The method enables a practitioner to determine the probability that a screened patient is positive for prostate cancer.

Le procédé permet à un praticien de déterminer la probabilité qu'un patient analysé soit atteint d'un cancer de la prostate.
