      1. Chemical detection of the proteins and lipids in the fat body cells from workers of Attini ants (Hymenoptera: Formicidae)

        Cell Biol Int 32(4):11 (2008) PMID 18272411

        The ultrastructural cytochemistry study and the chemical analysis carried out to examine the fat body of workers of the basal Attini Cyphomyrmex rimosus and Mycetarotes parallelus and the derived Acromyrmex disciger and Atta laevigata revealed very electrondense protein granules of varied sizes and...
      2. Aquaporins play a role in desiccation and freeze tolerance in larvae of the goldenrod gall fly, Eurosta solidaginis.

        J Exp Biol 211(Pt 7):1114-9 (2008) PMID 18344486

        We examined freeze-tolerant larvae of the goldenrod gall fly, Eurosta solidaginis, to determine whether aquaporins are present and if their presence promotes freeze tolerance of specific tissues. Immunoblotting with mammalian anti-AQP2, -AQP3 and -AQP4 revealed corresponding aquaporin homologues in...
      3. Induction of tyrosine hydroxylase gene expression by bacteria in the fat body of eri-silkworm, Samia cynthia ricini

        Comp Biochem Physiol B Biochem Mol Biol 149(3):6 (2008) PMID 18178496

        A cDNA clone encoding tyrosine hydroxylase (TH) was isolated from larval fat body of immunized Samia cynthia ricini. In naive larvae, the TH gene was expressed only in the brain, but strongly induced in fat body and hemocytes after injecting UV-killed bacteria. The induction of the gene was rather s...
      4. Expression of functional human (pro)renin receptor in silkworm (Bombyx mori) larvae using BmMNPV bacmid.

        Biotechnol Appl Biochem 49(Pt 3):195-202 (2008) PMID 17705788

        The circulating RA (renin-angiotensin) system is essential for the regulation of blood pressure and electrolyte balance. Recently, plasma prorenin has been reported to significantly increase its level in diabetes and to be possibly non-proteolytically activated by binding to the PRR [(pro)renin rece...
      5. Drosophila lifespan control by dietary restriction independent of insulin-like signaling.

        Aging Cell 7(2):199-206 (2008) PMID 18221413 PMCID 2340190

        We aim to understand this potential overlap. We found that over-expression of dFOXO in head fat body extends lifespan and reduces steady-state mRNA abundance of insulin-like peptide-2 under conditions of high dietary yeast, but not when yeast is limiting. In contrast, conditions of DR that increase...
      6. Role of dFOXO in lifespan extension by dietary restriction in Drosophila melanogaster: not required, but its activity modulates the response...

        Aging Cell 7(2):187-98 (2008) PMID 18241326

        We used the fruitfly Drosophila melanogaster to investigate the responses to DR of flies mutant for the transcription factor dFOXO, the main transcription factor target of IIS. We found that lifespan extension by DR does not require dFOXO. However, flies with dFOXO overexpressed in the adult fat bod...
      7. The role of hemocytes, serine protease inhibitors and pathogen-associated patterns in prophenoloxidase activation in the desert locust, Schi...

        Peptides 29(2):7 (2008) PMID 18207608

        We show that in the desert locust, Schistocerca gregaria, hemocytes, challenged with microbial elicitors, are indispensable for the limited proteolytic activation of prophenoloxidase (proPO) in plasma. In addition, we assessed the influence of serine protease inhibitors on the induction of PO-activi...
      8. Carbohydrate and lipid metabolism in cockroach (Periplaneta americana) fat body are both activated by low and similar concentrations of Pera...

        Peptides 29(2):9 (2008) PMID 18215441

        Injection of 0.1 pmol of the octapeptide Peram-AKH II (pGlu-Leu-Thr-Phe-Thr-Pro-Asn-TrpNH(2)) elicits a significant hypertrehalosemic response in the American cockroach, Periplaneta americana; a maximal effect is obtained with 1pmol. The latter amount also lowers the level of neutral lipid (NL) and...
      9. Functional analysis of four Gloverin-like genes in the silkworm, Bombyx mori.

        Arch Insect Biochem Physiol 67(2):87-96 (2008) PMID 18076111

        We constructed a cDNA library from the fat body of Escherichia coli-challenged B. mori larvae. Based on the expressed sequence tag (EST) data and whole genome shotgun sequence analysis, we found four Gloverin-like genes, BmGlov1-4, in the Bombyx genome. Northern blot and RT-PCR analysis showed that...
      10. Vitellogenesis in the hematophagous Dipetalogaster maxima (Hemiptera: Reduviidae), a vector of Chagas' disease

        J Insect Physiol 54(2):10 (2008) PMID 18068184

        Oocyte extracts of anautogenous Dipetalogaster maxima were chromatographed on an ion-exchange column in order to purify vitellin (Vt), the main insect yolk protein precursor. Purified Vt (Mr ~443 kDa) was composed of four subunits with approximate molecular weights of 174, 170, 50, and 44 kDa. Polyc...
