The Lymantria dispar nucleopolyhedrovirus (LdMNPV) gene encoding the 25K FP protein has been cloned and sequenced. The 25K FP gene codes for a 217 amino acid protein with a predicted molecular mass of 24870 Da. Expression of the 25K FP protein in a rabbit reticulocyte system generated a 27 kDa protein, in close agreement with the molecular mass predicted from the nucleotide sequence. The gene i...
We previously demonstrated that polyhedron formation (PF) mutants arise at a high frequency during serial passage of the Lymantria dispar nucleopolyhedrovirus (LdMNPV) in the L. dispar 652Y cell line (J. M. Slavicek, N. Hayes-Plazolles, and M. E. Kelly, Biol. Control 5:251-261, 1995). Most of these PF mutants exhibited the traits of few polyhedra (FP) mutants; however, no large DNA insertions o...
seven geographic isolates of helicoverpa armigera npv were characterized by pcr-rflp techniques and their comparative virulence to second instar larvae of h. armigera (hã¼bner) were compared before and after exposure to simulated sunlight as well as open weather conditions on cotton and tomato plants. the pcr products of 25k fp region showed no difference among the isolates (780 bp). the pcr am...
In previous studies on the formation of Lymantria dispar nuclear polyhedrosis virus (LdMNPV) few polyhedra (FP) mutants, several polyhedron formation mutants (PFM) were identified that appeared to be unique. These viral mutants are being characterized to investigate the processes of polyhedron formation and virion occlusion. LdMNPV isolate PFM-1 is one of these mutants, and is described in this...
Amyloid-beta (Abeta) neurotoxicity is believed to contribute to the pathogenesis of Alzheimer's disease (AD). Previously we found that E2-25K/Hip-2, an E2 ubiquitin-conjugating enzyme, mediates Abeta neurotoxicity. Here, we report that E2-25K/Hip-2 modulates caspase-12 activity via the ubiquitin/proteasome system. Levels of endoplasmic reticulum (ER)-resident caspase-12 are strongly up-regulate...
The ubiquitin (Ub)-conjugating enzyme E2(25K) catalyzes the synthesis of multi-Ub chains in which successive Ub units are linked by an isopeptide bond involving the epsilon-amino group of Lys-48 of Ubn, and the COOH-terminal Gly residue of Ubn+1 (Chen, Z., and Pickart, C. M. (1990) J. Biol. Chem., 265, 21835-21842). We now describe the polymerase chain reaction (PCR)-based cloning of an E2(25K)...
Aphis glycines Matsumura (Hemiptera: Aphididae) can reduce the yield of aphid-susceptible soybean (Glycine max (L.) Merrill) cultivars. The Rag1 and Rag2 genes conferresistance to some biotypes of A. glycines. These genes individually can limit population growth of A. glycines and prevent yield loss. The impact of these genes when combined is not known. We compared the development of A. glycine...
Numerous preclinical studies have demonstrated that polycation mediated gene delivery systems successfully achieved efficient gene transfer into cells and animal models. However, results of their clinical trials to date have been disappointing. That self-assembled gene and polycation systems should be stable undergoing dilution in the body is one of the prerequisites to ensuring efficiency of g...
