The hemolymph protein HP19 of the rice moth, Corcyra cephalonica, mediates the 20-hydroxyecdysone (20E)-dependent acid phosphatase (ACP) activity at a nongenomic level. Affinity-purified polyclonal antibody against HP19 (αHP19-IgG) was used in the p

The activity of acid phosphatase (ACP) in insect fat bodies is stimulated by the steroid hormone 20-hydoxyecdysone (20E) in vivo. However, in fat bodies kept in culture, a factor from the hemolymph is required to enhance the ACP activity. We identifi

The process of receptor-mediated uptake of hexamerin storage proteins from insect haemolymph by fat body cells is a unique feature of the class Insecta. We identified the binding domains of the hexamerin receptor and the hexamerin ligand arylphorin i

Hexamerins are multifunctional insect storage proteins utilized during metamorphosis of holometabolous insects. These proteins are stage specifically taken up by the fat body cells from the haemolymph due to receptor-mediated endocytosis. The hexamer

Three distinct types of storage hexamerins are expressed in the "last-instar" larvae of the rice moth, Corcyra cephalonica. A cDNA expression library was constructed from fat body-RNA and screened with a polyclonal antibody raised against purified he

Regulation of energy metabolism is one of the major functions of steroid hormones. In this process, mitochondria, by way of oxidative phosphorylation, play a central role. Depending on the energy needs of the cell, on the tissue, on the developmental

In late larvae of the blowfly, Calliphora vicina, arylphorin and LSP-2 proteins, which belong to the class of hexamerins, are selectively taken up by the fat body from the haemolymph. Hexamerin endocytosis is mediated by a specific membrane-bound rec

We cloned and sequenced a full length cDNA coding for [Arg7]-corazonin in the greater wax moth Galleria mellonella. The deduced corazonin preprohormone consists of a nineteen amino acid signal peptide, the actual eleven amino acid corazonin sequence,

Glucocorticoid hormones regulate the transcription of nuclear genes by way of their cognate receptors. In addition, these hormones also modulate mitochondrial gene transcription by mechanisms which are as yet poorly understood. Using immunofluorescen

Insect silk genes attract attention by their precise territorial and developmental regulations and extremely high expression rates. Our present investigations demonstrated that the P25 silk gene of Galleria mellonella is down-regulated by ecdysteroid
