Abstract
Exposure to stressful life events increases the risk for psychiatric disorders. Mechanistic insight into the genetic factors moderating the impact of stress can increase our understanding of disease processes. Here, we test 3,662 single nucleotide polymorphisms (SNPs) from preselected expression quantitative trait loci in massively parallel reporter assays to identify genetic variants that modulate the activity of regulatory elements sensitive to glucocorticoids, important mediators of the stress response. Of the tested SNP sequences, 547 were located in glucocorticoid-responsive regulatory elements of which 233 showed allele-dependent activity. Transcripts regulated by these functional variants were enriched for those differentially expressed in psychiatric disorders in the postmortem brain. Phenome-wide Mendelian randomization analysis in 4,439 phenotypes revealed potentially causal associations specifically in neurobehavioral traits, including major depression and other psychiatric disorders. Finally, a functional gene score derived from these variants was significantly associated with differences in the physiological stress response, suggesting that these variants may alter disease risk by moderating the individual set point of the stress response.

Abstract
Incubation of rat isolated skeletal muscles (extensor digitorum longus) in the presence of 100 ng/ml of human recombinant interleukin-15 (IL-15) resulted in a significant decrease in total proteolytic rate, while it had no effect on total protein synthesis as measured by the incorporation of (14)C-phenylalanine into muscle protein. In addition, IL-15 had no effect on either amino acid uptake (as determined by the tissue uptake of labelled [1-(14)C]MeAIB) or alanine utilization by incubated skeletal muscles. Similarly, a single injection of IL-15 (100 microg/kg) in vivo did not result in any changes in amino acid uptake (as measured by the tissue uptake of alpha-[1-(14)C]AIB) or alanine metabolism, with the exception of alanine carbon incorporation into lipids, which was significantly increased in adipose tissue as a result of IL-15 administration. The results suggest that the main mechanism involved in the anabolic effects of IL-15 in skeletal muscle relies on a decrease in the proteolytic rate.
