“Single-chain insulins (SCIs) are single polypeptide chains in which the insulin B-chain links contiguously with the insulin A-chain via an uncleaved connecting peptide. Although direct linkage of insulin B- and A-chains produces SCIs with little insulin receptor binding, biologists have been interested in bioengineering

linker peptides that form a flexible reverse turn, allowing SCIs to activate insulin receptors. In this report, we have investigated a series of cDNAs intended to explore the significance of linker length, cleavability, and the impact of certain site-dependent residues for the bioactivity of recombinant SCIs on insulin receptors. SCI concentration is readily measured by RIA with a (proinsulin plus insulin)-specific polyclonal antibody. Although dibasic flanking residues may result in potential endoproteolytic susceptibility, a linker with

-Gln-Arg-flanking sequences resisted cleavage even in secretory granules, ensuring single-chain behavior. Effective SCIs exhibit favorable and specific binding with insulin receptors. SCIs with linkers bearing an Arg residue immediately preceding the A-chain were most bioactive, although efficient receptor interaction was inhibited as SCI linker length increased, approaching that observed for proinsulin. SCIs activate downstream metabolic signaling, stimulating selleck products glucose uptake into adipocytes and suppressing gluconeogenic OSI-906 chemical structure enzyme biosynthesis in hepatocytes, with only limited cross-reactivity on IGF-I receptors. SCIs might theoretically have utility either in immunotherapy or gene therapy in insulin-deficient diabetes. (Molecular Endocrinology 23: 679-688, 2009)”
“Nonhuman animals often use specific signals to initiate playful interactions. There is evidence also for different forms of play-maintenance. Playful encounters include out-of-context

and exaggerated behavioural sequences. Scientists have already collected knowledge about virtual size modification via acoustic signalling in particular animal species during competitive/agonistic interactions, but the same was unknown in playful encounters. Using the cross-modal matching paradigm, we tested whether dogs prefer to look at the picture of a matching size dog when they are offered two differently sized projected pictures simultaneously with a playback of a playful or a food-guarding growl. We found that dogs looked at the matching picture when they heard the food-guarding growl, but they looked at rather the larger than the matching size dog when play growls were played back. These are the first results to show that dogs may communicate an exaggerated body size by the means of their growls during play, which may help in maintaining or enhancing the playful interaction.
