Nucleolar Stress Due to Depletion of Nopp140 in Drosophila melanogaster
… into autophagic vesicles. We also found elevated phenoloxidase A3 levels in whole larval lysates and within the hemolymph of Nopp140-depleted larvae, coincident with the appearance of melanotic tumors. The occurrence of apoptosis, autophagy, and phenoloxidase A3 release to the hemolymph upon …

Laccase-1 in the pea aphid, Acyrthosiphon pisum (Harris)
… by insects during feeding. A laccase-type phenoloxidase has been identified in the pea aphid, Acyrthosiphon pisum (Harris) using a combination of substrates that react with laccase. Within the pea aphid, laccase-1 transcript was found to be localized within the gut and the salivary glands. …

Isozyme patterns of selected isolates of Pholiota in the stirps "Adiposa"
… of esterases, (alphanaphthylamidases), phenoloxidases (laccases and tyrosinases), and peroxidases on polyacrylamide gels. Harvesting of different isolates for protein extraction was carried out at comparable stages of development using dry weight determinations and respiration studies as …

The Effects of Pesticide Exposures on the Nutritional and Immune Health of the Honey Bee, Apis mellifera L.
… compared to the pesticide-untreated bees. Phenoloxidase activity was significantly increased in the coumaphos-treated individuals compared to the pesticide-untreated bees. Glucose oxidase activity was significantly increased in the chlorothalonil-treated individuals compared to the …

Molecular approaches to increasing resistance of wheat (Triticum aestivum L.) towards two insect pests; Cereal aphid (Sitobion avenae F.) and Wheat bulb fly (Delia coarctata Fallen).
… regulation of the proteolytic cascade leading to phenoloxidase activation and melanin production in vivo. DcCathL has potential as a biopesticide if it could be made effective when orally delivered. A cationic amino acid transporter from D. coarctata gut (DcCAAT) was also cloned as a target for …

Host-Parasite Interactions Within Food Webs
… component of damselfly immune function, the phenoloxidase (PO) cascade. I found that neither direct density-mediated effects, indirect, trait-mediated effects, nor combined effects of predators via natural selection affected total PO activity. Instead, PO levels increased with resource …

Biological control of the dry rot fungus <i>Serpula lacrymans</i>
… enzyme studies indicated that the phenoloxidase enzyme laccase was important in the defensive strategy of <i>S.lacrymans</i> and in the offensive strategy of <i>Trichoderma </i>isolates. These studies also showed that <i>S.lacrymans</i> may use laccase as a general stress enzyme as …

Mitocidal resistance in the ectoparasitic mite,Varroa destructor, and the relationship with its host Apis mellifera
… immune related genes increased in expression: Phenoloxidase and Hymenoptaecin. Changes in the expression of immune related genes following parasitization indicates that Varroa are affecting how the immune reposnse functions. To idenitify whether or not this change in the immune reponse was …
