The Genetic Link between Parkinson's Disease and the Kynurenine Pathway Is Still Missing.

ABSTRACT: Background. There is substantial evidence that the kynurenine pathway (KP) plays a role in the normal physiology of the brain and is involved in the pathology of neurodegenerative disorders such as Huntington's disease and Parkinson's disease (PD). Objective. We set out to investigate the potential roles in PD of single nucleotide polymorphisms (SNPs) from one of the key enzymes of the KP, kynurenine 3-monooxygenase (KMO). Methods. 105 unrelated, clinically definitive PD patients and 131 healthy controls were enrolled to investigate the possible effects of the different alleles of KMO. Fluorescently labeled TaqMan probes were used for allele discrimination. Results. None of the four investigated SNPs proved to be associated with PD or influenced the age at onset of the disease. Conclusions. The genetic link between the KP and PD is still missing. The investigated SNPs presumably do not appear to influence the function of KMO and probably do not contain binding sites for regulatory proteins of relevance in PD. This is the first study to assess the genetic background behind the biochemical alterations of the kynurenine pathway in PD, directing the attention to this previously unexamined field.

Project description:The origin and deep evolution of retroviruses remain largely unclear. It has been proposed that retroviruses might have originated from a Ty3/Gypsy retrotransposon, but all known Ty3/Gypsy retrotransposons are only distantly related to retroviruses. Retroviruses and some plant Athila/Tat elements (within Ty3/Gypsy retrotransposons) independently evolved a dual RNase H domain and an env/env-like gene. Here, we reported the discovery of a novel lineage of retrotransposons, designated Odin retrotransposons, in the genomes of eight sea anemones (order Actinaria) within the Cnidaria phylum. Odin retrotransposons exhibited unique genome features, encoding a dual RNase H domain (like retroviruses) but no env gene (like most Ty3/Gypsy retrotransposons). Phylogenetic analyses based on reverse transcriptase showed that Odin retrotransposons formed a sister group to lokiretroviruses, and lokiretroviruses and Odin retrotransposons together were sister to canonical retroviruses. Moreover, phylogenetic analyses based on RNase H and integrase also supported the hypothesis that Odin retrotransposons were sisters to lokiretroviruses. Lokiretroviruses and canonical retroviruses did not form a monophyletic group, indicating that lokiretroviruses and canonical retroviruses might represent two distinct virus families. Taken together, the discovery of Odin retrotransposons narrowed down the evolutionary gaps between retrotransposons and canonical retroviruses and lokiretroviruses. IMPORTANCE The origin of retroviruses remains largely unclear. In this study, we discovered a novel retrotransposon lineage, Odin retrotransposons, within the genomes of sea anemones (order Actinaria). In contrast to retroviruses and most retrotransposons, Odin retrotransposons encode a dual RNase H domain but no env gene. Phylogenetic analyses showed that Odin retrotransposons were sisters to lokiretroviruses, and lokiretroviruses and Odin retrotransposons were sisters to retroviruses, establishing an evolutionary framework to decipher the origin of retroviruses (canonical retroviruses and lokiretroviruses). Our results provided insights into the diversity and deep evolution of LTR retrotransposons closely related to retroviruses.

Project description:BackgroundDisturbances in mineral and bone metabolism represent one of the most complex complications of chronic kidney disease (CKD). Serotonin, a monoamine synthesized from tryptophan, may play a potential role in bone metabolism. Brain-derived serotonin exerts a positive effect on the bone structure by limiting bone resorption and enhancing bone formation. Tryptophan is the precursor not only to the serotonin but also and primarily to kynurenine metabolites. The ultimate aim of the present study was to determine the association between central kynurenine metabolism and biomechanical as well as geometrical properties of bone in the experimental model of the early stage of CKD.MethodsThirty-three Wistar rats were randomly divided into two groups (sham-operated and subtotal nephrectomized animals). Three months after surgery, serum samples were obtained for the determination of biochemical parameters, bone turnover biomarkers, and kynurenine pathway metabolites; tibias were collected for bone biomechanical, bone geometrical, and bone mass density analysis; brains were removed and divided into five regions for the determination of kynurenine pathway metabolites.ResultsSubtotal nephrectomized rats presented higher serum concentrations of creatinine, urea nitrogen, and parathyroid hormone, and developed hypocalcemia. Several biomechanical and geometrical parameters were significantly elevated in rats with experimentally induced CKD. Subtotal nephrectomized rats presented significantly higher kynurenine concentrations and kynurenine/tryptophan ratio and significantly lower tryptophan levels in all studied parts of the brain. Kynurenine in the frontal cortex and tryptophan in the hypothalamus and striatum correlated positively with the main parameters of bone biomechanics and bone geometry.DiscussionIn addition to the complex mineral, hormone, and metabolite changes, intensified central kynurenine turnover may play an important role in the development of bone changes in the course of CKD.

Project description:BackgroundFunctional traits are the primary biotic component driving organism influence on ecosystem functions; in consequence, traits are widely used in ecological research. However, most animal trait-based studies use easy-to-measure characteristics of species that are at best only weakly associated with functions. Animal-mediated pollination is a key ecosystem function and is likely to be influenced by pollinator traits, but to date no one has identified functional traits that are simple to measure and have good predictive power.MethodsHere, we show that a simple, easy to measure trait (hairiness) can predict pollinator effectiveness with high accuracy. We used a novel image analysis method to calculate entropy values for insect body surfaces as a measure of hairiness. We evaluated the power of our method for predicting pollinator effectiveness by regressing pollinator hairiness (entropy) against single visit pollen deposition (SVD) and pollen loads on insects. We used linear models and AICC model selection to determine which body regions were the best predictors of SVD and pollen load.ResultsWe found that hairiness can be used as a robust proxy of SVD. The best models for predicting SVD for the flower species Brassica rapa and Actinidia deliciosa were hairiness on the face and thorax as predictors (R2 = 0.98 and 0.91 respectively). The best model for predicting pollen load for B. rapa was hairiness on the face (R2 = 0.81).DiscussionWe suggest that the match between pollinator body region hairiness and plant reproductive structure morphology is a powerful predictor of pollinator effectiveness. We show that pollinator hairiness is strongly linked to pollination-an important ecosystem function, and provide a rigorous and time-efficient method for measuring hairiness. Identifying and accurately measuring key traits that drive ecosystem processes is critical as global change increasingly alters ecological communities, and subsequently, ecosystem functions worldwide.
