1.1.3.6 physiological function cholesterol oxidase from Bordetella species promotes irreversible cell apoptosis in lung adenocarcinoma by cholesterol oxidation in vitro and in vivo. COD-B treatment results in JNK and p38 phosphorylation, downregulation of Bcl-2, upregulation of Bax, activated caspase-3 and cytochrome C release, which likely responds to freshly produced hydrogen peroxide that accompanies cholesterol oxidation. COD-B leads to irreversible cell apoptosis by decreasing cholesterol content and increasing reactive oxygen species level. Cholesterol oxidase (COD) is a flavoprotein that catalyzes the oxidation of cholesterol to 4-cholesten-3-one with the reduction of oxygen to hydrogen peroxide. COD can convert membrane cholesterol to 4-cholesten-3-one and can inhibit the formation of lipid rafts. Different from other cholesterol-depleting agents, COD disrupts lipid rafts by displacing cholesterol with 4-cholesten-3-one. COD-B catalyzes the oxidation of membrane cholesterol in lung adenocarcinoma cell. When cells are pretreated with catalase before adding COD-B and cholesterol, the phosphorylation of Akt and ERK1/2 remaines attenuated compared with the group without catalase treatment. Catalase pretreatment also partially blocks the activation of caspase-3, effect of catalase on the COD-B-induced signaling response, overview. COD-B induces the reversible translocation of caveolin-1, which is involved in trafficking membrane cholesterol, in a cholesterol-reversable manner Bordetella sp.
