paternally expressed genes predominate in the placenta. | the discovery of genomic imprinting through studies of manipulated mouse embryos indicated that the paternal genome has a major influence on placental development. however, previous research has not demonstrated paternal bias in imprinted genes. we applied rna sequencing to trophoblast tissue from reciprocal hybrids of horse and donkey, where genotypic differences allowed parent-of-origin identification of most expressed genes. using this approach, we identified a core group of 15 ancient imprin ... | 2013 | 23754418 |
mule/huwe1/arf-bp1 suppresses ras-driven tumorigenesis by preventing c-myc/miz1-mediated down-regulation of p21 and p15. | tumorigenesis results from dysregulation of oncogenes and tumor suppressors that influence cellular proliferation, differentiation, apoptosis, and/or senescence. many gene products involved in these processes are substrates of the e3 ubiquitin ligase mule/huwe1/arf-bp1 (mule), but whether mule acts as an oncogene or tumor suppressor in vivo remains controversial. we generated k14cre;mule(flox/flox(y)) (mule kko) mice and subjected them to dmba/pma-induced skin carcinogenesis, which depends on on ... | 2013 | 23699408 |
migrating mule deer: effects of anthropogenically altered landscapes. | migration is an adaptive strategy that enables animals to enhance resource availability and reduce risk of predation at a broad geographic scale. ungulate migrations generally occur along traditional routes, many of which have been disrupted by anthropogenic disturbances. spring migration in ungulates is of particular importance for conservation planning, because it is closely coupled with timing of parturition. the degree to which oil and gas development affects migratory patterns, and whether ... | 2013 | 23691246 |
impacts of informal trails on vegetation and soils in the highest protected area in the southern hemisphere. | there is limited recreation ecology research in south america, especially studies looking at informal trails. impacts of informal trails formed by hikers and pack animals on vegetation and soils were assessed for the highest protected area in the southern hemisphere, aconcagua provincial park. the number of braided trails, their width and depth were surveyed at 30 sites along the main access route to mt aconcagua (6962 m a.s.l.). species composition, richness and cover were also measured on cont ... | 2013 | 23681405 |
evolution, reproduction and definition of life. | synthetic theory of evolution is a superior integrative biological theory. therefore, there is nothing surprising about the fact that multiple attempts of defining life are based on this theory. one of them even has a status of nasa's working definition. according to this definition, 'life is a self-sustained chemical system capable of undergoing darwinian evolution' luisi (orig life evol bios 28:613-622, 1998); cleland, chyba (orig life evol bios 32:387-393, 2002). this definition is often cons ... | 2014 | 23674095 |
is a diagnostic system based exclusively on agar gel immunodiffusion adequate for controlling the spread of equine infectious anaemia? | to improve the efficiency of the national equine infectious anaemia (eia) surveillance program in italy, a three-tiered diagnostic system has been adopted. this procedure involves initial screening by elisa (tier 1) with test-positive samples confirmed by the agar gel immunodiffusion test (agidt) (tier 2) and, in the case of elisa positive/agidt negative results, final determination by immunoblot (ib) (tier 3). during this evaluation, 74,880 samples, principally collected from two regions of cen ... | 2013 | 23618837 |
characterization of prdm9 in equids and sterility in mules. | prdm9 (meisetz) is the first speciation gene discovered in vertebrates conferring reproductive isolation. this locus encodes a meiosis-specific histone h3 methyltransferase that specifies meiotic recombination hotspots during gametogenesis. allelic differences in prdm9, characterized for a variable number of zinc finger (zf) domains, have been associated with hybrid sterility in male house mice via spermatogenic failure at the pachytene stage. the mule, a classic example of hybrid sterility in m ... | 2013 | 23613924 |
duration of action of a topical anaesthetic formulation for pain management of mulesing in sheep. | to investigate the effect of topical anaesthesia on 'mothering up' of lambs after mulesing and marking, and for pain alleviation over a 24-h period. | 2013 | 23521101 |
sex-specific development of spatial orientation is independent of peripubertal gonadal steroids. | prenatal exposure to androgens has been shown to modulate brain development, resulting in changed behavioral attitudes, sexual orientation and cognitive functions, including processing of spatial information. whether later changes in gonadotropic hormones during puberty induce further organizational effects within the brain is still insufficiently understood. the purpose of this study was to assess development of spatial orientation before and after the time of normal pubertal development, in an ... | 2013 | 23477973 |

risk-sensitive allocation in seasonal dynamics of fat and protein reserves in a long-lived mammal. | body reserves of numerous taxa follow seasonal rhythms that are a function of temporal patterns in food availability and life-history events; however, tests of the theory underlying the allocation of somatic reserves for long-lived organisms are rare, especially for free-ranging mammals. we evaluated the hypothesis that allocation of somatic reserves to survival (i.e., metabolic processes) and reproduction should be sensitive to current nutritional state relative to seasonal thresholds in those ... | 2013 | 23379674 |
usp7s-dependent inactivation of mule regulates dna damage signalling and repair. | the e3 ubiquitin ligase mule/arf-bp1 plays an important role in the cellular dna damage response by controlling base excision repair and p53 protein levels. however, how the activity of mule is regulated in response to dna damage is currently unknown. here, we report that the ser18-containing isoform of the usp7 deubiquitylation enzyme (usp7s) controls mule stability by preventing its self-ubiquitylation and subsequent proteasomal degradation. we find that in response to dna damage, downregulati ... | 2013 | 23275561 |
the past, present and future of domestic equines in tanzania. | equines are minor species in tanzania's array of domestic livestock. attempts to use them for transport by early explorers from the mid-nineteenth century usually failed. donkeys were used extensively as pack animals to complement human porters by both british and german forces in the first world war, but their advantages were often outweighed by slow progress and competition with troops and porters for water, and they died in huge numbers. the british had regular cavalry troops in their campaig ... | 2013 | 24834000 |
between- and within-breed variations of spine characteristics in sheep. | implementing the use of spine traits in a commercial breeding program has been seen to improve meat production from the carcass of larger-bodied pigs. the aim of this study was to assess the extent of variation in spine characteristics within and between breeds of sheep and to investigate the association with body length and tissues traits to deliberate if a similar approach could be applicable in the sheep sector. spine traits (vertebrae number, vn; spine region length, spl; individual vertebra ... | 2013 | 23243168 |
identification of piroplasms isolated from asymptomatic equine species from southern spain. | the aim of the study was to detect the presence of genetic material of equine piroplasmas and to determine the species isolates from apparently healthy equids, including horses, donkeys and mules, in southern spain. blood samples were collected from 135 animals to assess the presence of dna from equine piroplasmas using pcr. babesia (b.) caballi dna was detected in blood samples of three horses and one donkey, while theileria (t.) equi dna was confirmed in blood of 19 horses, three mules and one ... | 2012 | 23227769 |
a piecewise linear modeling approach for testing competing theories of habitat selection: an example with mule deer in northern winter ranges. | habitat selection fundamentally drives the distribution of organisms across landscapes; density-dependent habitat selection (ddhs) is considered a central component of ecological theories explaining habitat use and population regulation. a preponderance of ddhs theories is based on ideal distributions, such that organisms select habitat according to either the ideal free, despotic, or pre-emptive distributions. models that can be used to simultaneously test competing ddhs theories are desirable ... | 2013 | 23203509 |
primary cilia in the basal cells of equine epididymis: a serendipitous finding. | occurrence of a solitary cilium was an unexpected discovery while studying the ultrastructure of epididymal epithelium in equidae. primary cilia were detected in epididymal basal cells of all individuals of the equines studied - horses, donkey and mules - independently from age and tract of the duct, emerging from the basal cell surface and insinuating into the intercellular spaces. more rarely solitary cilia occurred also at the luminal surface of the principal cells. the ciliary apparatus was ... | 2013 | 23182032 |
challenges and proposed solutions for more accurate serological diagnosis of equine infectious anaemia. | serological diagnosis of equine infectious anaemia virus (eiav) infections has depended mainly on the agar gel immunodiffusion test (agidt). this study documents the presence of eiav genetic sequences in a number of persistently infected horses and mules whose serums were interpreted as negative/equivocal on agidt, but positive on more than one elisa test and in immunoblot tests. strategies designed to take advantage of the combined strengths of the elisa and agidt are shown effective in a natio ... | 2013 | 23161812 |
summer watering patterns of mule deer in the great basin desert, usa: implications of differential use by individuals and the sexes for management of water resources. | changes in the abundance and distribution of free water can negatively influence wildlife in arid regions. free water is considered a limiting factor for mule deer (odocoileus hemionus) in the great basin desert. consequently, a better understanding of differential use of water by individuals and the sexes could influence the conservation and management of mule deer and water resources in their habitats. we deployed remote cameras at all known water sources (13 wildlife water developments and 4 ... | 2012 | 23125557 |
index selection in terminal sires improves lamb performance at finishing. | lamb meat is often perceived by consumers as fatty, and consumption has decreased in recent decades. a lean growth index was developed in the uk for terminal sire breeds to increase carcass lean content and constrain fat content at a constant age end point. the purposes of this study were 1) to evaluate the effects of index selection of terminal sires on their crossbred offspring at finishing and 2) to evaluate its effectiveness within terminal sire breeds. approximately 70% of lambs marketed in ... | 2013 | 23100579 |

fundamental frequency is key to response of female deer to juvenile distress calls. | considerable attention is currently devoted to understanding acoustic mechanisms underlying animal responses to heterospecific vocalizations. a further complication ensues when the response of two species is asymmetrical. for example, white-tailed deer females approach a speaker only when it plays distress calls of conspecific fawns. mule deer females approach when hearing distress calls of either white-tailed deer or mule deer. we hypothesized that selective species such as white-tailed deer re ... | 2013 | 23022571 |
behavioural responses of lambs to plastic clips as an alternative procedure to mulesing. | compare the effects on the behaviour of lambs of applying occlusive plastic clips, as an alternative procedure to surgical mulesing, with tail docking, surgical mulesing and a control treatment. | 2012 | 23004227 |
gastrointestinal nematode burden in working equids from humid tropical areas of central veracruz, mexico, and its relationship with body condition and haematological values. | the east coast of veracruz, mexico, has an important equine population used for working in rural production systems. the objectives of this study were (1) to calculate the prevalence of tropical working equids (donkeys, mules and horses) infected with gastrointestinal nematodes (gins) and the gins involved, and (2) to measure the body condition score (bcs) and haematological values for each working equid and its relationship with faecal worm egg count (epg). one hundred and forty working equids ... | 2013 | 22992947 |
spermatogonial stem cell markers and niche in equids. | spermatogonial stem cells (sscs) are the foundation of spermatogenesis and are located in a highly dynamic microenvironment called "niche" that influences all aspects of stem cell function, including homing, self-renewal and differentiation. several studies have recently identified specific proteins that regulate the fate of sscs. these studies also aimed at identifying surface markers that would facilitate the isolation of these cells in different vertebrate species. the present study is the fi ... | 2012 | 22937157 |
evaluating apparent competition in limiting the recovery of an endangered ungulate. | predation can disproportionately affect endangered prey populations when generalist predators are numerically linked to more abundant primary prey. apparent competition, the term for this phenomenon, has been increasingly implicated in the declines of endangered prey populations. we examined the potential for apparent competition to limit the recovery of sierra nevada bighorn sheep (ovis canadensis sierrae), an endangered subspecies under the us endangered species act. using a combination of loc ... | 2013 | 22791131 |
stress-induced phosphorylation and proteasomal degradation of mitofusin 2 facilitates mitochondrial fragmentation and apoptosis. | mitochondria play central roles in integrating pro- and antiapoptotic stimuli, and jnk is well known to have roles in activating apoptotic pathways. we establish a critical link between stress-induced jnk activation, mitofusin 2, which is an essential component of the mitochondrial outer membrane fusion apparatus, and the ubiquitin-proteasome system (ups). jnk phosphorylation of mitofusin 2 in response to cellular stress leads to recruitment of the ubiquitin ligase (e3) huwe1/mule/arf-bp1/hecth9 ... | 2012 | 22748923 |
social relations in a mixed group of mules, ponies and donkeys reflect differences in equid type. | donkeys and mules are frequently kept as companion animals for horses and ponies, with these different equids often being considered a homogenous group. however, the extent to which domestic equids form inter-specific bonds and display similar social behaviour when living in a mixed herd has not previously been studied. here we compare the social organization of these three (sub)species when housed together, providing the first systematic analysis of how genetic hybridization is expressed in the ... | 2012 | 22709577 |

nibbs-search for fast and accurate prediction of phenotype-biased metabolic systems. | understanding of genotype-phenotype associations is important not only for furthering our knowledge on internal cellular processes, but also essential for providing the foundation necessary for genetic engineering of microorganisms for industrial use (e.g., production of bioenergy or biofuels). however, genotype-phenotype associations alone do not provide enough information to alter an organism's genome to either suppress or exhibit a phenotype. it is important to look at the phenotype-related g ... | 2012 | 22589706 |
modeling the relationships between quality and biochemical composition of fatty liver in mule ducks. | the fatty liver of mule ducks (i.e., french "foie gras") is the most valuable product in duck production systems. its quality is measured by the technological yield, which is the opposite of the fat loss during cooking. the purpose of this study was to determine whether biochemical measures of fatty liver could be used to accurately predict the technological yield (ty). ninety-one male mule ducks were bred, overfed, and slaughtered under commercial conditions. fatty liver weight (flw) and bioche ... | 2012 | 22585814 |
the double life of mule in preeclamptic and iugr placentae. | the e3 ubiquitin ligase mule (mcl-1 ubiquitin ligases e3) targets myeloid cell leukemia factor 1 (mcl-1) and tumor suppressor p53 for proteasomal degradation. although mcl-1 and p53 have been implicated in trophoblast cell death in preeclampsia (pe) and intrauterine growth restriction (iugr), the mechanisms regulating their expression in the human placenta remains elusive. herein, we investigated mule's involvement in regulating mcl-1 and p53 degradation during normal and abnormal (pe, iugr) pla ... | 2012 | 22552282 |
survival patterns in white-tailed and mule deer after oral inoculation with a standardized, conspecific prion dose. | we orally inoculated white-tailed deer (odocoileus virginianus) and mule deer (odocoileus hemionus) with a standardized, conspecific prion dose and collected biologic samples throughout the disease course. mule deer (prnp genotype 225ss) and prnp genotype 96gg white-tailed deer succumbed along similar trajectories, but 96gs- and 96ss-genotype individuals tended to survive longer. | 2012 | 22493138 |
mutator-like elements with multiple long terminal inverted repeats in plants. | mutator-like transposable elements (mules) are widespread in plants and the majority have long terminal inverted repeats (tirs), which distinguish them from other dna transposons. it is known that the long tirs of mutator elements harbor transposase binding sites and promoters for transcription, indicating that the tir sequence is critical for transposition and for expression of sequences between the tirs. here, we report the presence of mules with multiple tirs mostly located in tandem. these e ... | 2012 | 22474413 |
