Insect fat body: energy, metabolism, and regulation.
TLDR
This review focuses on energy storage and release in insects and summarizes current understanding of the mechanisms underlying these processes in insects. Expand
Lipid storage and mobilization in insects: current status and future directions.
TLDR
This paper discusses recent studies on the mobilization of diacylglycerol from the fat body in response to adipokinetic hormone and the present understanding of the role of the lipid transfer particle and lipophorin receptors in lipid delivery between lipoph orin and tissues. Expand
Conformation of a Group 2 Late Embryogenesis Abundant Protein from Soybean. Evidence of Poly (l-Proline)-type II Structure1
TLDR
The ability of the protein to remain in a highly extended conformation at low temperatures could constitute the basis of the functional role of GmDHN1 in the prevention of freezing, desiccation, ionic, or osmotic stress-related damage to macromolecular structures. Expand
Deep sequencing of small RNA libraries reveals dynamic regulation of conserved and novel microRNAs and microRNA-stars during silkworm development
TLDR
This work identified 101 homologs of conserved miRNAs, 14 species-specific and two antisense mi RNAs in the silkworm, and provided deeper insights into changes in conserved and novel miRNA and miRNA* accumulation during development. Expand
Activation of the Lipid Droplet Controls the Rate of Lipolysis of Triglycerides in the Insect Fat Body*
TLDR
It is concluded that the lipolysis in fat body adipocytes is controlled by the activation of the lipid droplet, and Lsdp1 is the main target of PKA, suggesting that this protein is a major player in theactivation of lipolyses in insects. Expand
Function and structure of lipid storage droplet protein 1 studied in lipoprotein complexes.
TLDR
The purification of recombinant Lsd1 and its reconstitution with lipids to form lipoprotein complexes suitable for functional and structural studies are described and it is shown that PKA mediated phosphorylation of L SD1 promoted a 1.7-fold activation of the main fat body lipase demonstrating the direct link between LSD1 phosphorylated and activation of lipolysis. Expand
The main triglyceride-lipase from the insect fat body is an active phospholipase A1: identification and characterization Published, JLR Papers in Press, September 27, 2006.
TLDR
It was observed that the activation of lipolysis in vivo is accompanied by activation of the hydrolysis of phospholipids of the lipid droplets, suggesting that the PL activity of the insect TG-lipase could be required to allow access of the lipase to TG molecules contained in the core of the cholesterol droplets. Expand
Purification and properties of a phosphorylatable triacylglycerol lipase from the fat body of an insect, Manduca sexta.
TLDR
A triacylglycerol lipase, presumably the first enzyme involved in the mobilization of lipid from the insect fat body, has been purified to homogeneity from the fat body of Manduca sexta and it is suggested that this fat body lipase could be analogous to the "hormone-sensitive lipase" of vertebrate adipose tissue. Expand
Calcium and cAMP are second messengers in the adipokinetic hormone-induced lipolysis of triacylglycerols in Manduca sexta fat body.
TLDR
The findings indicate that the action of adipokinetic hormone in mobilizing lipids from the insect fat body involves both cAMP and calcium as intracellular messengers. Expand
Expression of lipid storage droplet protein-1 may define the role of AKH as a lipid mobilizing hormone in Manduca sexta.
TLDR
A link between AKH-stimulated lipolysis in the fat body and the expression of LSD1 is suggested and the deduced protein sequence showed a high degree of conservation compared to other insect Lsd1s, particularly in the central region of the protein (amino acids 211-276) in which the predicted lipid binding helices are found.
