1 Proline oxidase (POX), a mitochondrial inner-membrane protein, catalyzes the rate-limiting oxidation of proline to pyrroline- 5-carboxylate (P5C). Proline proline dehydrogenase 1 Homo sapiens
2 Proline oxidase (POX), a mitochondrial inner-membrane protein, catalyzes the rate-limiting oxidation of proline to pyrroline- 5-carboxylate (P5C). Proline proline dehydrogenase 1 Homo sapiens
3 To further investigate the molecular basis of POX-induced apoptosis, we utilized the DLD-1.POX cells to show that cells overproducing POX exhibit an L-proline-dependent apoptotic response. Proline proline dehydrogenase 1 Homo sapiens
4 To further investigate the molecular basis of POX-induced apoptosis, we utilized the DLD-1.POX cells to show that cells overproducing POX exhibit an L-proline-dependent apoptotic response. Proline proline dehydrogenase 1 Homo sapiens
5 To further investigate the molecular basis of POX-induced apoptosis, we utilized the DLD-1.POX cells to show that cells overproducing POX exhibit an L-proline-dependent apoptotic response. Proline proline dehydrogenase 1 Homo sapiens
6 The apoptotic effect is specific for L-proline, detectable at 0.2 mM, maximal at 1 mM, and occurs during 48-72 h following the addition of L-proline to cells with maximally induced POX. Proline proline dehydrogenase 1 Homo sapiens
7 The apoptotic effect is specific for L-proline, detectable at 0.2 mM, maximal at 1 mM, and occurs during 48-72 h following the addition of L-proline to cells with maximally induced POX. Proline proline dehydrogenase 1 Homo sapiens
8 We conclude that in the presence of proline, high POX activity is sufficient to induce mitochondria-mediated apoptosis. Proline proline dehydrogenase 1 Homo sapiens
