 Context examples 

This agent is extensively hydroxylated by cytochrome P450 2E1 (CYP2E1) to 6-hydroxychlorzoxazone (HCZ),11,12 which is subsequently glucuronidated and eliminated renally.

(Chlorzoxazone, NCI Thesaurus)

Apoptosis regulation by Bcl-2 family proteins occurs as family members form complexes that enter the mitochondrial membrane, regulating the release of cytochrome c and other proteins.

(Mitochondria in Apoptotic Signaling Pathway, NCI Thesaurus/BIOCARTA)

This allele, which encodes protein AF1q, plays a role in both depolarization of and release of cytochrome c by the mitochondrion.

(MLLT11 wt Allele, NCI Thesaurus)

The mitochondrial stress pathway begins with the release of cytochrome c from mitochondria, which then interacts with Apaf-1, causing self-cleavage and activation of caspase-9.

Its metabolites, via cytochrome P450 oxidation, are potent alkylating agents and causes DNA adducts, which is responsible for the carcinogenic effect.

(Bromoethene, NCI Thesaurus)

Azamulin is a highly selective inhibitor of cytochrome P450 3A4 (CYP3A4).

(Azamulin, NCI Thesaurus)

The scientists got their inspiration from nature by focusing on a protein called cytochrome P450 2E1, or 2E1 for short. 2E1 is present in all mammals, including humans.

Beta-naphthoflavone is an inducer of the hepatic cytochrome p450 CYP1A1 and CYP1A2.

Members of the MDR/TAP subfamily are involved in multi-drug resistance as well as antigen presentation. newitional factors involved in detoxification are the P450 cytochromes (CYPs), glutathione-S-transferase (GST).
