Ethoxyresorufin (ER)-O-deethylation (EROD) activity has been widely used to assess cytochrome P450 1A (CYP1A) activity. The kinetics of CYP1A activity have been well characterized in the liver microsomes. However, studies in kidney microsomes are limited due to the much lower EROD activity in this organ. Here, we developed and validated a sensitive UPLC-MS/MS assay for the characterization of the EROD activity in the rat kidney microsomes. In a 50 µL reaction mixture, rat kidney microsomes (0.25 mg/mL) were incubated with ER (0.1–5 µM) and NADPH (1 mM) for 10 min. Acidic solvents, such as trichloroacetic acid or formic …

Oxygen levels tend to remain at a steady state concentration in the Earth’s atmosphere, yet in some bodies of water, they can fluctuate and decrease drastically. Many organisms that inhabit the swamps, lakes, streams, and parts of the ocean where this occurs have evolved adaptations to manage this environmental uncertainty and continue normal oxygen consumption. The Lwamunda swamp in Uganda is chronically hypoxic, yet it is home to many species, including the electric fish Petrocephalus degeni. P. degeni are unusual by nature of their immense brain, and the Lwamunda swamp appears ill-suited for maintaining this large, metabolically active organ. To …

Betaine lipids are a class of membrane lipids with betaine head groups. Three betaine lipids are known - diacylglyceryltrimethylhomoserine (DGTS), diacylglycerylhydroxymethylalanine (DGTA), and diacylglycerylcarboxymethylcholine (DGCC). Betaine lipids are most common in algae, although DGTS, the most common betaine lipid, is also found in many bacteria and fungi. Organisms which produce betaine lipids (especially DGTS) often don’t produce phosphatidylcholine (PtdCho), and DGTS structure resembles PtdCho structure without any phosphorous, leading to the hypothesis that betaine lipids may substitute for phospholipids in some organisms. This has been confirmed by discoveries that some organisms are capable of switching their membrane composition from PtdCho …
