Alternates Peroxisomal Contents in Response to Trophic Conditions.

is a model green microalga capable of heterotrophic growth on acetic acid but not fatty acids, despite containing a full complement of genes for β-oxidation. Recent reports indicate that the alga preferentially sequesters, rather than breaks down, lipid acyl chains as a means to rebuild its membranes rapidly. Here, we assemble a list of potential peroxins (PEXs) required for peroxisomal biogenesis to suggest that has a complete set of peroxisome biogenesis factors.

Neuroprotective and neurotoxic outcomes of androgens and estrogens in an oxidative stress environment.

Background: The role of sex hormones on cellular function is unclear. Studies show androgens and estrogens are protective in the CNS, whereas other studies found no effects or damaging effects. Furthermore, sex differences have been observed in multiple oxidative stress-associated CNS disorders, such as Alzheimer's disease, depression, and Parkinson's disease.
