Characterization of lin-42/period transcriptional regulation by the Ikaros/hunchback-family transcription factor ZTF-16 in Caenorhabditis elegans
The gene lin-42 is an ortholog of the mammalian period gene, a component of the circadian pathway that converts environmental stimuli into behavioral and physiological outputs over 24 hours. Mammalian period also regulates adult stem cell differentiation, although this function is poorly …

Examination of the expression of genes and proteins controlling M. longissimus thoracis et lumborum growth in steers
… investigated the effect of sire breed and genetic merit for growth potential of the transcriptional regulation of the somatotropic axis followed by a proteomic approach to assess differentially abundant proteins. Following this, a second study was set up to examine the compensatory growth …

A Mutational Analysis of the Period Locus of Drosophila Melanogaster
<p>The period (per) gene of Drosophila melanogaster is fundamentally involved in the generation of biological rhythms. Three classes of per mutations which alter circadian periodicity have been identified: per<sup>s</sup> mutants have circadian behavioral rhythms of 19h instead of 24h; per mutants …

Genetic Studies on the Circadian Clock in the Model Organism Drosophila Melanogaster
… to be elucidated. In this study a variety of genetic and molecular approaches was used to identify and characterize genes that are involved in circadian rhythms and that may shed light on the gaps in the model. In an F1 screen for altered period length of the circadian locomotor activity cycle …

Nutritional modulation of the transcriptome in adipose, liver, and polymorphonuclear leukocytes in peripartal dairy cows
… effects of body condition score (BCS) on adipose gene expression, or supplemental rumen-protected methionine on liver and polymorphonuclear (PMNL) gene expression of fatty acid-sensing G-protein coupled receptors (GPCRs), and 2) evaluate the effect of overfeeding during the dry period on the PMNL …

Immune function, gene expression, blood indices and performance in transition dairy cows affected by diet and inflammation
The transition period is associated with the peak incidence of production problems, metabolic disorders and infectious diseases in dairy cows (Drackley, 1999). During this time the cow’s immune system seems to be weakened; it is apparent that metabolic challenges associated with the onset of …
