| Protein phosphorylation on certain serine or threonine residues preceding proline (Ser/Thr-Pro) is a pivotal signaling mechanism in diverse cellular processes. Pin1 is a highly conserved enzyme that isomerizes only the phosphorylated Ser/Thr-Pro bonds in certain proteins, thereby inducing conformational changes. Although much protein is phosphorylated in the ovary, the role of Pin1 in the ovary is still unknown. The purpose of this study is to investigate the effects of gonadotropins on protein and mRNA expression of Pin1 in mice ovaries. Quantitative PCR analysis showed that the expression of Pin1 mRNA significantly increased in the ovaries of equine chorionic gonadotropin (eCG)-treated mice compared with those of untreated mice (P<0.05). However,... |

| ABSTRACT Feed costs are the main limiting factors in poultry industry and alternative sources of food and/or feed supplements to optimize the bird´s life cycle and to extend their production period need to be explored. This study evaluated morphometric parameters of the small intestine and gonadotropin transcript levels in Isa Brown laying hens supplemented with glutamine + glutamic acid (Aminogut®) during a second production cycle. Molting was induced and groups of 100 hens each, were supplemented with 0, 0.8, 1.6 or 2.4% Aminogut® in their diet. At the end of the experimental period, tissue sections from duodenum, jejunum and ileum were processed by the Hematoxylin-Eosin technique and samples from hypothalamus and hypophysis were collected for RT-PCR... |
