  1. Overexpression of the cytochrome c oxidase subunit I gene associated with a pyrethroid resistant strain of German cockroaches, Blattella ger...

    Insect Biochemistry and Molecular Biology 33(10):1043 (2003) PMID 14505698

    I gene (COXI) was identified and isolated as a differentially expressed gene between insecticide susceptible ACY and resistant Apyr-R German cockroach strains using PCR-selected subtractive hybridization and cDNA array techniques. The cDNA sequence of COXI has an open reading frame of 1533 nucleotid...
  2. Isolation, characterization and chemical synthesis of a new insect defensin from Chironomus plumosus (Diptera).

    Insect Biochemistry and Molecular Biology 28(12):1059 (1998) PMID 9887520

    We have isolated two 36-residue peptides from this hemolymph which are active against Gram-positive bacteria. The peptides are novel members of the insect defensin family and their sequences present marked differences with those of insect defensins isolated from other dipteran species. We have devel...
  3. A hydrophobic peptide (VAP-peptide) of the silkworm, Bombyx mori: structure, expression and an enhancing function of diapause hormone activi...

    Insect Biochemistry and Molecular Biology 28(2):75 (1998) PMID 9639873

    We have recently identified a unique lipophilic peptide (VAP-peptide) with diapause egg inducing activity in the silkworm, Bombyx mori (Imai et al., 1996). The cloning and sequencing of cDNA encoding VAP-peptide have demonstrated that the deduced amino acid sequence consisted of 84 amino acid residu...
  4. Protein purification and cDNA cloning of a cecropin-like peptide from the larvae of fall webworm (Hyphantria cunea).

    Insect Biochemistry and Molecular Biology 27(8-9):711 (1997) PMID 9443371

    We obtained three other cDNAs exhibiting high sequence similarity with Hyphantria cecropin A. We synthesized the C-terminally amidated peptide of 35 residues based on the deduced sequence of the isolated cDNA of Hyphantria cecropin A. The synthetic peptide exhibited strong antibacterial activity aga...
  5. Host plant-specific remodeling of midgut physiology in the generalist insect herbivore Trichoplusia ni.

    Insect Biochemistry and Molecular Biology 50:58 (2014) PMID 24727019

    We used defended and non-defended plant genotypes to study how variation in chemical defense affects midgut responses of the lepidopteran herbivore Trichoplusia ni, which is a pest of a wide variety of native and cultivated plants. The genome-wide midgut transcriptional response of T. ni larvae to g...
  6. Genomic analysis of the interactions between social environment and social communication systems in honey bees (Apis mellifera).

    Insect Biochemistry and Molecular Biology 47:36 (2014) PMID 24486775

    We investigate the effect of social environment on genome-wide expression patterns in the MG, to determine how social context modulates expression of genes that, in turn alter social environment. We used microarrays to examine the MGs of virgin and mated queens, and queenright (QR) and queenless (QL...
  7. Molecular and functional characterization of CYP6BQ23, a cytochrome P450 conferring resistance to pyrethroids in European populations of pol...

    Insect Biochemistry and Molecular Biology 45:18 (2014) PMID 24316412

    We demonstrated by detection of 4-hydroxy tau-fluvalinate using ESI-TOF MS/MS that functionally expressed CYP6BQ23 also metabolizes tau-fluvalinate. A protein model was generated and subsequent docking simulations revealed the predicted substrate-binding mode of both deltamethrin and tau-fluvalinate...
  8. Involvement of reactive oxygen species in PTTH-stimulated ecdysteroidogenesis in prothoracic glands of the silkworm, Bombyx mori.

    Insect Biochemistry and Molecular Biology 43(9):859 (2013) PMID 23851285

    I and III in the electron transport chain and the mitochondrial inner membrane potential (ΔΨ) contribute to PTTH-stimulated ROS production. In addition, PTTH-stimulated ecdysteroidogenesis was greatly inhibited by treatment with either NAC or mitochondrial inhibitors (rotenone, antimycin A, FCCP, an...
  9. MicroRNA-281 regulates the expression of ecdysone receptor (EcR) isoform B in the silkworm, Bombyx mori.

    Insect Biochemistry and Molecular Biology 43(8):692 (2013) PMID 23707601

    We report that a conserved insect miRNA, microRNA-281 (miR-281), regulates the ecdysone receptor (EcR), in an isoform-specific manner in the silkworm Bombyx mori. The B. mori EcR (BmEcR) gene encodes three isoforms: BmEcR-A, BmEcR-B1 and BmEcR-B2. The 3'UTR regions of A and B genes, which contain mu...
  10. Extensive inter- and intraspecific venom variation in closely related parasites targeting the same host: the case of Leptopilina parasitoids...

    Insect Biochemistry and Molecular Biology 43(7):601 (2013) PMID 23557852

    We have identified the main secreted proteins in the venom of Leptopilina heterotoma (Gotheron strain, 66 proteins) and of two well-characterized strains of Leptopilina boulardi, ISm and ISy (65 and 49 proteins, respectively). Results revealed significant quantitative differences in venom components...
