Tumor-suppressing 15-Lipoxygenase-2
Lipoxygenases (LOX) comprise a family of non-heme-iron-containing proteins that cata-lyze the dioxygenation of polyunsaturated fatty acids to form bioactive lipids. Metabolism of arachidonic acid by LOXs leads to the formation of regioisomeric cis/trans-conjugated hydroxyeicosatetraenoic acids (HeTes), leukot-rienes, lipoxins, and hepoxilins. Dependent on the predominant position of the incorpo...
متن کاملSubcellular localization and tumor-suppressive functions of 15-lipoxygenase 2 (15-LOX2) and its splice variants.
15-Lipoxygenase 2 (15-LOX2), the most abundant arachidonate (AA)-metabolizing enzyme expressed in adult human prostate, is a negative cell-cycle regulator in normal human prostate epithelial cells. Here we study the subcellular distribution of 15-LOX2 and report its tumor-suppressive functions. Immunocytochemistry and biochemical fractionation reveal that 15-LOX2 is expressed at multiple subcel...

متن کاملTumor-suppressive functions of 15-Lipoxygenase-2 and RB1CC1 in prostate cancer
15-Lipoxygenase-2 (15-LOX2) is a human-specific lipid-peroxidizing enzyme most prominently expressed in epithelial cells of normal human prostate but downregulated or completely lost in>70% of prostate cancer (PCa) cases. Transgenic expression of 15-LOX2 in the mouse prostate surprisingly causes hyperplasia. Here we first provide evidence that 15-LOX2-induced prostatic hyperplasia does not prog...
متن کاملMonocyte 15-lipoxygenase gene expression requires ERK1/2 MAPK activity.
IL-13 induces profound expression of 15-lipoxygenase (15-LO) in primary human monocytes. Our studies have defined the functional IL-13R complex, association of Jaks with the receptor components, and the tyrosine phosphorylation of several Stat molecules in response to IL-13. Furthermore, we identified both p38MAPK and protein kinase Cδ as critical regulators of 15-LO expression. In this study, ...
