Coenzyme Q (CoQ) is an essential player in the respiratory electron transport chain and is the only lipid-soluble antioxidant synthesized endogenously in mammalian and yeast cells. In humans, genetic mutations, pathologies, certain medical treatments, and aging, result in CoQ deficiencies...

Cells were incubated with 12-(1-pyrene)-dodecanoic acid (P12), a long-chain fatty acid to which a pyrene ring has been attached covalently. This acid was transported across the plasma membranes of cells and subsequently incorporated into their neutral lipids and phospholipids. Irradiation...

We isolated peroxisome biogenesis mutants from Chinese hamster ovary (CHO) cells, using the 9-(1'-pyrene)nonanol/ultraviolet (P9OH/ UV) method and wild-type CHO-K1 cells that had been stably transfected with cDNA encoding Pex2p (formerly peroxisome assembly factor-1, PAF-1). Three mutant cell clones, ZP110...
