Proline reduces brain cytochrome c oxidase: prevention by antioxidants

open access: yesInternational Journal of Developmental Neuroscience, 2007
In the present study, we initially investigated the in vivo (acute and chronic) and in vitro effects of proline on cytochrome c oxidase (complex IV) activity in rat cerebral cortex to test the hypothesis that proline might alter energy metabolism and ...

Overexpression of proline oxidase induces proline-dependent and mitochondria-mediated apoptosis

Molecular and Cellular Biochemistry, 2006
Proline oxidase (POX), a mitochondrial inner-membrane protein, catalyzes the rate-limiting oxidation of proline to pyrroline- 5-carboxylate (P5C). Previously we showed that overexpression of POX is associated with generation of reactive oxygen species (ROS) and apoptosis in POX-inducible colorectal cancer cells, DLD-1.POX.

Regulation and function of proline oxidase under nutrient stress [PDF]

open access: yesJournal of Cellular Biochemistry, 2009
AbstractUnder conditions of nutrient stress, cells switch to a survival mode catabolizing cellular and tissue constituents for energy. Proline metabolism is especially important in nutrient stress because proline is readily available from the breakdown of extracellular matrix (ECM), and the degradation of proline through the proline cycle initiated by ...

Proline dehydrogenase (oxidase) in cancer

open access: yesBioFactors, 2012
AbstractProline dehydrogenase (oxidase, PRODH/POX), the first enzyme in the proline degradative pathway, plays a special role in tumorigenesis and tumor development. Proline metabolism catalyzed by PRODH/POX is closely linked with the tricarboxylic acid (TCA) cycle and urea cycle.

Proline Oxidase (POX) as A Target for Cancer Therapy

Current Drug Targets, 2015
Proline dehydrogenase/proline oxidase (PRODH/POX) is an enzyme catalyzing the first step of proline degradation, during which ROS and/or ATP is generated. POX is widely distributed in living organisms and is responsible for a number of regulatory processes such as redox homeostasis, osmotic adaptation, cell signaling and oxidative stress.
