Toxic responses of Perna viridis hepatopancreas exposed to DDT, benzo(a)pyrene and their mixture uncovered by iTRAQ-based proteomics and NMR-based metabolomics.

Aquat Toxicol. 2017 Sep 11;192:48-57

Abstract
Dichlorodiphenyltrichloroethane (DDT) and benzo(a)pyrene (BaP) are environmental estrogens (EEs) that are ubiquitous in the marine environment. In the present study, we integrated isobaric tags for relative and absolute quantitation (iTRAQ)-based proteomic and nuclear magnetic resonance (NMR)-based metabolomic approaches to explore the toxic responses of green mussel hepatopancreas exposed to DDT (10?g/L), BaP (10?g/L) and their mixture. The metabolic responses indicated that BaP primarily disturbed energy metabolism and osmotic regulation in the hepatopancreas of the male green mussel P. viridis. Both DDT and the mixture of DDT and BaP perturbed the energy metabolism and osmotic regulation in P. viridis. The proteomic responses revealed that BaP affected the proteins involved in energy metabolism, material transformation, cytoskeleton, stress responses, reproduction and development in green mussels. DDT exposure could change the proteins involved in primary metabolism, stress responses, cytoskeleton and signal transduction. However, the mixture of DDT and BaP altered proteins associated with material and energy metabolism, stress responses, signal transduction, reproduction and development, cytoskeleton and apoptosis. This study showed that iTRAQ-based proteomic and NMR-based metabolomic approaches could effectively elucidate the essential molecular mechanism of disturbances in hepatopancreas function of green mussels exposed to environmental estrogens.

[U. of Ottawa NMR Facility Blog] Cross Polarization Based Mixture Resolution in Solids
Cross Polarization Based Mixture Resolution in Solids One of the most common techniques used to collect solid-state NMR data for spin I = ˝ nuclides is a combination of cross polarization (CP) and magic angle spinning (MAS). CPMAS provides high sensitivity from the CP and high chemical shift resolution from the MAS. Furthermore, the scan repetition rate depends on the shorter relaxation time of the protons rather than the longer relaxation time of the spin I = ˝ nuclide therefore, more scans can be collected per unit time. It must be remembered however, that the success of the CP...
