    JHBP
    Opis:
    Juvenile hormone (JH) is essential for multiple physiological processes: it controls larval development, metamorphosis and adult reproduction. In insect hemolymph more than 99 % of JH is bound to juvenile hormone binding protein (JHBP), which protects JH from degradation by nonspecific hydrolases and serves as a carrier to supply the hormone to the target tissues. In Galleria mellonella hemolymph, JHBP is found in a complex with lipid-binding high molecular weight proteins (HMWP) and this interaction is enhanced in the presence of JH. In this report, we present studies on the interaction of JHBP with low molecular weight proteins (LMWP) in the hemolymph. Using ligand blotting we found that JHBP interacts with a protein of about 44 kDa. To identify the protein that preferentially binds JHBP, a LMWP fraction was applied to a Sepharose-bound JHBP and, after washing, the column was eluted with free JHBP acting as a specific competitor or with carbonic anhydrase as a negative control. The eluted proteins were separated by SDS/PAGE and analyzed by mass spectrometry. Isocitrate dehydrogenase was identified as a component of the supramolecular complex of JHBP with hemolymph proteins.

    Opis:
    The hemolymph juvenile hormone binding protein (JHBP) from Galleria mellonella contains two disulphide bridges/molecule and no free Cys residues. An alignment of primary structures of other Lepidopteran JHBPs indicates that Cys residues, equivalent to Cys10,17,151,195 in G. mellonellaJHBP, may be involved in -S-S- bridge formation.

    Opis:
    The insects are a class of invertebrates within the arthropod phylum that have a chitinous exoskeleton. The leaf eating insects obtain their nutrients and growth promoting biocompounds from the variable or specific flora available for them. The plants on earth are the richest source of metabolites including juvenile hormone analogues for leaf eating insects like silkworm, Bombyx mori (L). Some of plant origin metabolites are acting as insects juvenoids for insect lives. They serve to take pause in the progression of metamorphosis through arresting some of the biochemical reactions including chitin synthesis or accelerating progression through other biochemical pathways in the larval body of insects. The ten microliters of various concentrations of acetone solution of Fernasol Methyl Ether (FME) and each selected monoterpene compounds (Myrcene; Camphene; Cymene; Limonene and Eucalyptol ) were used for topical application to individual larval instars of silkworm, Bombyx mori (L) (Race: PM x CSR2) at 48 hours after the fourth moult. The integument chitin of untreated control larvae; acetone treated control; FME treated larvae and monoterpene treated larvae was estimated at 120 hours after the fourth moult. Topical application of selected concentrations of acetone solutions of selected monoterpenes to fifth instar larvae of silkworm, Bombyx mori (L) (Race: PM x CSR2) was found reflected into the reduction in the deposition of chitin in the larval body wall. The reduction in body wall chitin was found ranging from zero to hundred percent. The plot of concentrations of acetone solutions of FME and monoterepene compounds and percent reduction in the body wall chitin was found exhibiting a characteristic Sigmoid form of displacement, which herewith titled as “Punyamayee Baramati Dose Response Curve”. Since the effects of juvenoids involve the inhibition of metamorphosis through reduction in chitin deposition, it is possible to express the concentration (dose) applied in terms of ID50 value. The ID50 value of juvenoid contents of FME and selected monoterpene compounds can be defined as the specific unit (microgram), which enable to chitin to deposit fifty percent less in the body wall of larvae (In comparison with untreated control). Accordingly, the ID50 value calculated from the “Punyamayee Baramati Dose Response Curves” for FME was found measured 0.08 mg/ml. The ID50 values for monoterpene compounds: Myrcene; Camphene; Cymene; Limonene and Eucalyptol were found measured: 0.116; 0.122; 0.164; 0.172 and 0.208 mg/ml respectively. Acetone soluble juvenoid content of terpene compounds may be utilized efficiently for the fortified development of fifth instars of silkworm, Bombyx mori (L) and thereby, the cocoon quality. Sigmoid (S-form) “Baramati Dose Response Curve” may help for quantitative estimation of juvenoid contents of various terpene compounds and terpenoids.

    Opis:
    Adult males of Schistocerca gregaria turn yellow when they become sexually mature. This is due to the deposition in the cuticle of a male-specific Yellow Protein (YP), of which the amino acid sequence is known. Yellowing only happens in crowd-reared (gregarious) males, and results from the deposition of a specific ‘Yellow Protein’. If individual males (solitarious) are isolated after the adult emergence, they become sexually mature but they do not turn yellow. On the basis of a partial YP-mRNA sequence, we established a reverse transcriptase polymerase chain reaction (RT-PCR) assay to study the developmental expression of YP in crowd-reared males, isolated-reared males and females. In crowd-reared adult males the transcription of YP gene started from day 5 on, and reached a maximum at day 12. The effects of juvenile hormone (JH), insulin (bovine), corazonin, ecdysone and 20 0H-ecdysone (20E) on the regulation of YP-mRNA synthesis were also investigated. JH made the cuticle turn yellow and, as shown by RT-PCR, YP-mRNA was induced. The effect of 100 μg JHIII was stronger than that of 10 μg. Insulin was only effective in inducing YP-mRNA synthesis at high dose (19 μg) and after more days (18 d). Corazonin and 20E made the cuticle turn black, but no YP-mRNA synthesis was observed. Ecdysone (10 and 100 μg) showed no effect on body coloration and YP-mRNA. Thus, JH was found to be the most potent inducer among the hormones tested.
