Ceramides induce programmed cell death in Arabidopsis cells in a calcium-dependent manner

While the role of C2-ceramide in the induction of programmed cell death (PCD) in animal systems has been well documented, little is known of its role in plant cells...

Keywords: Apoptosis, calcium signalling, reactive oxygen species

Relationship between neurological outcome and early oxidative changes in erythrocytes in head injury patients

Background: Experimental data indicate that destructive oxidative events reach their peak within the first 24 h after trauma in head injury (HI) and that brain damage occurring due to this impact can be the cause of death or irreversible permanent disabilities in affected patients.

Methods: Venous blood samples were obtained from 50 HI patients within 24 h of trauma onset and from 30 age- and sex-matched normal controls (NC)...

Keywords: erythrocytes, glutathione, lipid peroxidation, outcome, reactive oxygen species

Adrenodoxin (Adx) and CYP11A1 (P450scc) induce apoptosis by the generation of reactive oxygen species in mitochondria

Mitochondrial cytochrome P450 systems are an indispensable component of mammalian steroid biosynthesis; they catalyze regio- and stereo-specific steroid hydroxylations and consist of three protein entities: adrenodoxin reductase (AdR), adrenodoxin (Adx), and a mitochondrial cytochrome P450 enzyme, e.g., CYP11A1 (P450 side chain cleavage, P450scc)...

Keywords: adrenodoxin, Apoptosis, CYP11A1, cytochrome P450, electron transfer chain, mitochondria, reactive oxygen species, steroid hydroxylation
