baicalein | the 12LO inhibitor induces a 2-2.5fold increase in cell death, which appears to result from apoptosis, as indicated by DNA fragmentation, activation of procaspase 3 to caspase 3 and cytochrome c release from the mitochondria to the cytosol. This apoptosis can be prevented by treatment with the 12LO product, 12 hydroxyeicosatetraenoic acid (12HETE) | Homo sapiens |

malfunction | the 12LO inhibitor induces a 2-2.5fold increase in cell death, which appears to result from apoptosis, as indicated by DNA fragmentation, activation of procaspase 3 to caspase 3 and cytochrome c release from the mitochondria to the cytosol. Human platelet-type 12LO-antisense knockdown, by either plasmid transfection or adeno-associated virus (AAV) infection also induces substantial VSMC death over controls, which can also be prevented by treatment with 12HETE, but not 5HETE. Hence, biochemical 12LO inhibition or 12LO-antisense knockdown in VSMC can induce programmed cell death | Homo sapiens |
physiological function | 12-lipoxygenase (12LO) is a dioxygenase enzyme that incorporates molecular oxygen into unsaturated fatty acids such as arachidonic acid at carbon position 12. Arachidonate LOs and their products play an important role in mediating growth factor induced tumor cell proliferation and appear to enhance the growth and migration of vascular smooth muscle cells, VSMC. VSMC proliferation is essential in vascular wall function as well as plaque formation and the inhibition of the renin angiotensin system can induce VSMC apoptosis | Homo sapiens |
