Abstract

Male gametogenesis involves both mitotic divisions to amplify germ cell progenitors that gradually differentiate and meiotic divisions. Centrosomal regulation is essential for both types of divisions, with centrioles remaining tightly paired during the interphase. Here, we generated and characterized the phenotype of mutant mice devoid of Cep250/C-Nap1, a gene encoding for a docking protein for fibers linking centrioles, and characterized their phenotype. The Cep250-/- mice presented with no major defects, apart from male infertility due to a reduction in the spermatogonial pool and the meiotic blockade. Spermatogonial stem cells expressing Zbtb16 were not affected, whereas the differentiating spermatogonia were vastly lost. These cells displayed abnormal γH2AX-staining, accompanied by an increase in the apoptotic rate. The few germ cells that survived at this stage, entered the meiotic prophase I and were arrested at a pachytene-like stage, likely due to synapsis defects and the unrepaired DNA double-strand breaks. In these cells, centrosomes split up precociously, with γ-tubulin foci being separated whereas these were closely associated in wild-type cells. Interestingly, this lack of cohesion was also observed in wild-type female meiocytes, likely explaining the normal fertility of Cep250-/- female mice. Taken together, this study proposes a specific requirement of centrosome cohesion in the male germline, with a crucial role of CEP250 in both differentiating spermatogonia and meiotic spermatocytes.

Abstract

Neuropathies are neurodegenerative diseases affecting humans and other mammals. Many genetic causes have been identified so far, including mutations of genes encoding proteins involved in mitochondrial dynamics. Recently, the "Turning calves syndrome", a novel sensorimotor polyneuropathy was described in the French Rouge-des-Prés cattle breed. In the present study, we determined that this hereditary disease resulted from a single nucleotide substitution in SLC25A46, a gene encoding a protein of the mitochondrial carrier family. This mutation caused an apparent damaging amino-acid substitution. To better understand the function of this protein, we knocked out the Slc25a46 gene in a mouse model. This alteration affected not only the nervous system but also altered general metabolism, resulting in premature mortality. Based on optic microscopy examination, electron microscopy and on biochemical, metabolic and proteomic analyses, we showed that the Slc25a46 disruption caused a fusion/fission imbalance and an abnormal mitochondrial architecture that disturbed mitochondrial metabolism. These data extended the range of phenotypes associated with Slc25a46 dysfunction. Moreover, this Slc25a46 knock-out mouse model should be useful to further elucidate the role of SLC25A46 in mitochondrial dynamics.

Abstract

In the course of evolution, pecorans (i.e., higher ruminants) developed a remarkable diversity of osseous cranial appendages, collectively referred to as “headgear,” which likely share the same origin and genetic basis. However, the nature and function of the genetic determinants underlying their number and position remain elusive. Jacob and other rare populations of sheep and goats are characterized by polyceraty, the presence of more than two horns. Here, we characterize distinct POLYCERATE alleles in each species, both associated with defective HOXD1 function. We show that haploinsufficiency at this locus results in the splitting of horn bud primordia, likely following the abnormal extension of an initial morphogenetic field. These results highlight the key role played by this gene in headgear patterning and illustrate the evolutionary co-option of a gene involved in the early development of bilateria to properly fix the position and number of these distinctive organs of Bovidae.

Abstract

To put a Respiratory Syncytial Virus (RSV) vaccine onto the market, new vaccination strategies combining scientific and technical innovations need to be explored. Such a vaccine would also need to be adapted to the vaccination of young children that are the principal victims of acute RSV infection. In the present project, we describe the development and the preclinical evaluation of an original epicutaneous RSV vaccine that combines two technologies: Viaskin® epicutaneous patches as a delivery platform and RSV N-nanorings (N) as a subunit antigen. Such a needle-free vaccine may have a better acceptability for the vaccination of sensible population such as infants since it does not require any skin preparation. Moreover, this self-applicative vaccine would overcome some issues associated to injectable vaccines such as the requirement of sterile medical devices, the need of skilled health-care professionals and the necessity of stringent store conditions. Here, we demonstrate that Viaskin® patches loaded with a formulation containing N-nanorings (Viaskin®-N) are highly immunogenic in mice and promotes a Th1/Th17 oriented immune response. More importantly, Viaskin®-N epicutaneous vaccine confers a high level of protection against viral replication upon RSV challenge in mice, without exacerbating clinical symptoms. In swine, which provides the best experimental model for the transcutaneous passage of drug/antigen in human skin, we have shown that GFP fluorescent N-nanorings, delivered epicutaneously with Viaskin® patches, are taken up by epidermal Langerhans cells. We have also demonstrated that Viaskin®-N induced a significant RSV N-specific T-cell response in pig. In conclusion, Viaskin®-N epicutaneous vaccine seems efficient to protect against RSV infection in animal model.

Abstract

The two standardized assays for testing hygienic behavior in Apis mellifera in the field are the freeze-killed brood (FKB) and the pin-killed brood (PKB) assays. Correlation between the two tests is still in debate. It has been argued that the PKB assay was predictive of Varroa nonreproduction. We measured the agreement between the two methods in two apiaries with 36 and 59 colonies, respectively. The agreement between the two assays was very poor with a 95% limit of agreement greater than 100%. These assays and the SMR (Suppression of Mite Reproduction) trait were also measured in 21 single drone inseminated colonies infested with Varroa and with varying SMR efficacy. A PKB assay result of >46% at 24 h predicted an SMR trait >40% with a sensitivity and a specificity of 0.727 and 0.90, respectively, whereas the FKB assay did not exhibit any predictive value. In conclusion, the PKB and FKB assays are not correlated, but the PKB assay predicted SMR with a good accuracy.

Abstract

In humans, the clinical and molecular characterization of sporadic syndromes is often hindered by the small number of patients and the difficulty in developing animal models for severe dominant conditions. Here we show that the availability of large data sets of whole-genome sequences, high-density SNP chip genotypes and extensive recording of phenotype offers an unprecedented opportunity to quickly dissect the genetic architecture of severe dominant conditions in livestock. We report on the identification of seven dominant de novo mutations in CHD7, COL1A1, COL2A1, COPA, and MITF and exploit the structure of cattle populations to describe their clinical consequences and map modifier loci. Moreover, we demonstrate that the emergence of recessive genetic defects can be monitored by detecting de novo deleterious mutations in the genome of bulls used for artificial insemination. These results demonstrate the attractiveness of cattle as a model species in the post genomic era, particularly to confirm the genetic aetiology of isolated clinical case reports in humans., Scientific Reports, 7 (1), ISSN:2045-2322

Abstract

Synthetic peptides derived from the heptad repeat (HR) of fusion (F) proteins can be used as dominant negative inhibitors to inhibit the fusion mechanism of class I viral F proteins. Here, we have performed a stapled-peptide scan across the HR2 domain of the respiratory syncytial virus (RSV) F protein with the aim to identify a minimal domain capable of disrupting the formation of the postfusion six-helix bundle required for viral cell entry. Constraining the peptides with a single staple was not sufficient to inhibit RSV infection. However, the insertion of double staples led to the identification of novel short stapled peptides that display nanomolar potency in HEp-2 cells and are exceptionally robust to proteolytic degradation. By replacing each amino acid of the peptides by an alanine, we found that the substitution of residues 506 to 509, located in a patch of polar contacts between HR2 and HR1, severely affected inhibition. Finally, we show that intranasal delivery of the most potent peptide to BALB/c mice significantly decreased RSV infection in upper and lower respiratory tracts. The discovery of this minimal HR2 sequence as a means for inhibition of RSV infection provides the basis for further medicinal chemistry efforts toward developing RSV fusion antivirals.

Abstract

International audience; Asthma is a chronic, non-curable, multifactorial disease with increasing incidence in industrialcountries. This study evaluates the direct contribution of lung microbial components in allergicasthma in mice. Germ-Free and Specific-Pathogen-Free mice display similar susceptibilities to HouseDust Mice-induced allergic asthma, indicating that the absence of bacteria confers no protection orincreased risk to aeroallergens. In early life, allergic asthma changes the pattern of lung microbiota,and lung bacteria reciprocally modulate aeroallergen responsiveness. Primo-colonizing cultivablestrains were screened for their immunoregulatory properties following their isolation from neonatallungs. Intranasal inoculation of lung bacteria influenced the outcome of allergic asthma development:the strain CNCM I 4970 exacerbated some asthma features whereas the pro-Th1 strain CNCM I 4969had protective effects. Thus, we confirm that appropriate bacterial lung stimuli during early life arecritical for susceptibility to allergic asthma in young adults

Abstract

Olfactory receptors are G protein-coupled receptors. Some of them are expressed in tumor cells, such as the OR51E2 receptor overexpressed in LNCaP prostate cancer cells. It is considered a prostate tumor marker. We previously demonstrated that this receptor is able to promote LNCaP cell invasiveness in vitro upon stimulation with its odorant agonist beta-ionone, leading to increased generation of metastases in vivo. In the present study, we show that even a relatively short exposure to beta-ionone is sufficient to promote metastasis emergence. Moreover, alpha-ionone, considered an OR51E2 antagonist, in fact promotes prostate tumor growth in vivo. The combination of alpha-ionone with beta-ionone triggers a higher increase in the total tumor burden than each molecule alone. To support the in vivo results, we demonstrate in vitro that alpha-ionone is a real agonist of OR51E2, mainly sustaining LNCaP cell growth, while beta-ionone mainly promotes cell invasiveness. So, while structurally close, alpha-ionone and beta-ionone appear to induce different cellular effects, both leading to increased tumor aggressiveness. This behaviour could be explained by a different coupling to downstream effectors, as it has been reported for the so-called biased ligands of other G protein-coupled receptors.

Abstract

Neuropathies are neurodegenerative diseases affecting humans and other mammals. Many genetic causes have been identified so far, including mutations of genes encoding proteins involved in mitochondrial dynamics. Recently, the “Turning calves syndrome”, a novel sensorimotor polyneuropathy was described in the French Rouge-des-Prés cattle breed. In the present study, we determined that this hereditary disease resulted from a single nucleotide substitution in SLC25A46, a gene encoding a protein of the mitochondrial carrier family. This mutation caused an apparent damaging amino-acid substitution. To better understand the function of this protein, we knocked out the Slc25a46 gene in a mouse model. This alteration affected not only the nervous system but also altered general metabolism, resulting in premature mortality. Based on optic microscopy examination, electron microscopy and on biochemical, metabolic and proteomic analyses, we showed that the Slc25a46 disruption caused a fusion/fission imbalance and an abnormal mitochondrial architecture that disturbed mitochondrial metabolism. These data extended the range of phenotypes associated with Slc25a46 dysfunction. Moreover, this Slc25a46 knock-out mouse model should be useful to further elucidate the role of SLC25A46 in mitochondrial dynamics., Author summary Mitochondria are essential organelles, the site of numerous biochemical reactions, with a critical role in delivering energy to cells, particularly in the nervous system. Consequently, disrupted mitochondrial function often results in neurodegenerative diseases, in humans and in other mammals. Herein, we determined that the “Turning calves syndrome”, a new hereditary sensorimotor polyneuropathy in the French Rouge-des-Prés cattle breed was due to a single substitution in SLC25A46, a gene encoding a protein of the mitochondrial carrier family. We created a mouse knock-out model and determined that disruption of this gene dramatically disturbed mitochondrial dynamics in various organs that resulted in altered metabolism and early death, indirectly confirming the gene identification in cattle. Moreover, our novel findings extended the range of phenotypes associated with polymorphisms of this gene and help to elucidate the role of SLC25A46 in mitochondrial function.

Abstract

The two standardized assays for testing hygienic behavior in Apis mellifera in the field are the freeze-killed brood (FKB) and the pin-killed brood (PKB) assays. Correlation between the two tests is still in debate. It has been argued that the PKB assay was predictive of Varroa nonreproduction. We measured the agreement between the two methods in two apiaries with 36 and 59 colonies, respectively. The agreement between the two assays was very poor with a 95% limit of agreement greater than 100%. These assays and the SMR (Suppression of Mite Reproduction) trait were also measured in 21 single drone inseminated colonies infested with Varroa and with varying SMR efficacy. A PKB assay result of >46% at 24 h predicted an SMR trait >40% with a sensitivity and a specificity of 0.727 and 0.90, respectively, whereas the FKB assay did not exhibit any predictive value. In conclusion, the PKB and FKB assays are not correlated, but the PKB assay predicted SMR with a good accuracy. [ABSTRACT FROM AUTHOR]

Abstract

International audience; AbstractSleeping disease in rainbow trout is characterized by an abnormal swimming behaviour of the fish which stay on their side at the bottom of the tanks. This sign is due to extensive necrosis and atrophy of red skeletal muscle induced by the sleeping disease virus (SDV), also called salmonid alphavirus 2. Infections of humans with arthritogenic alphaviruses, such as Chikungunya virus (CHIKV), are global causes of debilitating musculoskeletal diseases. The mechanisms by which the virus causes these pathologies are poorly understood due to the restrictive availability of animal models capable of reproducing the full spectrum of the disease. Nevertheless, it has been shown that CHIKV exhibits a particular tropism for muscle stem cells also known as satellite cells. Thus, SDV and its host constitute a relevant model to study in details the virus-induced muscle atrophy, the pathophysiological consequences of the infection of a particular cell-type in the skeletal muscle, and the regeneration of the muscle tissue in survivors together with the possible virus persistence. To study a putative SDV tropism for that particular cell type, we established an in vivo and ex vivo rainbow trout model of SDV-induced atrophy of the skeletal muscle. This experimental model allows reproducing the full panel of clinical signs observed during a natural infection since the transmission of the virus is arthropod-borne independent. The virus tropism in the muscle tissue was studied by immunohistochemistry together with the kinetics of the muscle atrophy, and the muscle regeneration post-infection was observed. In parallel, an ex vivo model of SDV infection of rainbow trout satellite cells was developed and virus replication and persistence in that particular cell type was followed up to 73 days post-infection. These results constitute the first observation of a specific SDV tropism for the muscle satellite cells.

Abstract

International audience; In order to be able to put an RSV vaccine onto the market, new vaccination strategies combining scientific and technical innovation need to be explored. In the present project, we describe the development and the non-clinical evaluation of an original epicutaneous RSV vaccine that combines two patented technologies: Viaskin® epicutaneous patches developed by DBV Technologies as a delivery platform, and RSV N-nanorings fused to the F epitope targeted by palivizumab (N-FsII) developed by the French National Institute for Agronomical Research (INRA) as a subunit antigen. We have demonstrated that Viaskin® loaded with a formulation containing N-FsII antigen (Viaskin®- N-FsII) is highly immunogenic in mice and promote a Th1/Th17 oriented immune response. More importantly, Viaskin®-N-FsII epicutaneous vaccine confers a high level of protection against viral replication upon RSV challenge in mice, without exacerbating clinical symptoms. In swine, which provides the best experimental model for the cutaneous passage of drug/antigen in human skin, we have demonstrated that Viaskin®-N-FsII induced a significant RSV N-specific T-cell response. Using this animal model, we have also shown that GFP fluorescent N-nanorings, delivered epicutaneously with Viaskin® patches, are taken up by epidermal Langerhans cells. In conclusion, Viaskin®-N-FsII epicutaneous vaccine seems efficient to protect against RSV infection in animal model. Moreover, since no injection is required and no skin conditioning is needed before application of patches, Viaskin®-N-FsII epicutaneous vaccine would provide a pertinent and safe solution for the vaccination of newborns.

Abstract

International audience; Lactation performance is dependent on both the genetic characteristics and the environmental conditions surrounding lactating cows. However, individual variations can still be observed within a given breed under similar environmental conditions. The role of the environment between birth and lactation could be better appreciated in cloned cows, which are presumed to be genetically identical, but differences in lactation performance between cloned and noncloned cows first need to be clearly evaluated. Conflicting results have been described in the literature, so our aim was to clarify this situation. Nine cloned Prim' Holstein cows were produced by the transfer of nuclei from a single fibroblast cell line after cell fusion with enucleated oocytes. The cloned cows and 9 noncloned counterparts were raised under similar conditions. Milk production and composition were recorded monthly from calving until 200 d in milk. At 67 d in milk, biopsies were sampled from the rear quarter of the udder, their mammary epithelial cell content was evaluated, and mammary cell renewal, RNA, and DNA were then analyzed in relevant samples. The results showed that milk production did not differ significantly between cloned and noncloned cows, but milk protein and fat contents were less variable in cloned cows. Furthermore, milk fat yield and contents were lower in cloned cows during early lactation. At around 67 DIM, milk fat and protein yields, as well as milk fat, protein, and lactose contents, were also lower in cloned cows. These lower yields could be linked to the higher apoptotic rate observed in cloned cows. Apoptosis is triggered by insulin-like factor growth binding protein 5 (IGFBP5) and plasminogen activator inhibitor (PAI), which both interact with CSN1S2. During our experiments, CSN1S2 transcript levels were lower in the mammary gland of cloned cows. The mammary cell apoptotic rate observed in cloned cows may have been related to the higher levels of DNA (cytosine-5-)-methyltransferase 1 (DNMT1) transcripts, coding for products that maintain the epigenetic status of cells. We conclude, therefore, that milk production in cloned cows differs slightly from that of noncloned cows. These differences may be due, in part, to a higher incidence of subclinical mastitis. They were associated with differences in cell apoptosis and linked to variations in DNMT1 mRNA. However, milk protein and fat contents were more similar among cloned cows than among noncloned cows.

Abstract

International audience; High variability in bovine milk production depends both on genetic and environmental factors. Whereas genomic selection has contributed to greatly improve milk production, mechanisms underlying the influence of the environment are mostly unknow. They can be studied using cloned cows (obtained through nuclear transfer), presumed to have identical genomes. Nine Prim’Holstein cloned cows and nine non-cloned cows were produced at similar periods of the year, raised in similar conditions, and inseminated at the age of 18 months. Eight cloned and 7 non-cloned cows delivered. Body condition score at calving was lower (ΔBSC=-0.6) for cloned cows (P=0.03). During the first 200 days in milk (DIM), milk yield varied greatly among animals but was similar between the two groups, whereas milk fat and protein contents varied less in cloned cows (P=0.004 and 0.09). Around 67 DIM, fat, protein and lactose contents (P

Abstract

In humans, the clinical and molecular characterization of sporadic syndromes is often hindered by the small number of patients and the difficulty in developing animal models for severe dominant conditions. Here we show that the availability of large data sets of whole-genome sequences, high-density SNP chip genotypes and extensive recording of phenotype offers an unprecedented opportunity to quickly dissect the genetic architecture of severe dominant conditions in livestock. We report on the identification of seven dominant de novo mutations in CHD7, COL1A1, COL2A1, COPA, and MITF and exploit the structure of cattle populations to describe their clinical consequences and map modifier loci. Moreover, we demonstrate that the emergence of recessive genetic defects can be monitored by detecting de novo deleterious mutations in the genome of bulls used for artificial insemination. These results demonstrate the attractiveness of cattle as a model species in the post genomic era, particularly to confirm the genetic aetiology of isolated clinical case reports in humans.

Abstract

Asthma is a chronic, non-curable, multifactorial disease with increasing incidence in industrial countries. This study evaluates the direct contribution of lung microbial components in allergic asthma in mice. Germ-Free and Specific-Pathogen-Free mice display similar susceptibilities to House Dust Mice-induced allergic asthma, indicating that the absence of bacteria confers no protection or increased risk to aeroallergens. In early life, allergic asthma changes the pattern of lung microbiota, and lung bacteria reciprocally modulate aeroallergen responsiveness. Primo-colonizing cultivable strains were screened for their immunoregulatory properties following their isolation from neonatal lungs. Intranasal inoculation of lung bacteria influenced the outcome of allergic asthma development: the strain CNCM I 4970 exacerbated some asthma features whereas the pro-Th1 strain CNCM I 4969 had protective effects. Thus, we confirm that appropriate bacterial lung stimuli during early life are critical for susceptibility to allergic asthma in young adults.

Abstract

Neuropathies are neurodegenerative diseases affecting humans and other mammals. Many genetic causes have been identified so far, including mutations of genes encoding proteins involved in mitochondrial dynamics. Recently, the "Turning calves syndrome", a novel sensorimotor polyneuropathy was described in the French Rouge-des-Prés cattle breed. In the present study, we determined that this hereditary disease resulted from a single nucleotide substitution in SLC25A46, a gene encoding a protein of the mitochondrial carrier family. This mutation caused an apparent damaging amino-acid substitution. To better understand the function of this protein, we knocked out the Slc25a46 gene in a mouse model. This alteration affected not only the nervous system but also altered general metabolism, resulting in premature mortality. Based on optic microscopy examination, electron microscopy and on biochemical, metabolic and proteomic analyses, we showed that the Slc25a46 disruption caused a fusion/fission imbalance and an abnormal mitochondrial architecture that disturbed mitochondrial metabolism. These data extended the range of phenotypes associated with Slc25a46 dysfunction. Moreover, this Slc25a46 knock-out mouse model should be useful to further elucidate the role of SLC25A46 in mitochondrial dynamics.

Abstract

Olfactory receptors are G protein-coupled receptors. Some of them are expressed in tumor cells, such as the OR51E2 receptor overexpressed in LNCaP prostate cancer cells. It is considered a prostate tumor marker. We previously demonstrated that this receptor is able to promote LNCaP cell invasiveness in vitro upon stimulation with its odorant agonist β-ionone, leading to increased generation of metastases in vivo. In the present study, we show that even a relatively short exposure to β-ionone is sufficient to promote metastasis emergence. Moreover, α-ionone, considered an OR51E2 antagonist, in fact promotes prostate tumor growth in vivo. The combination of α-ionone with β-ionone triggers a higher increase in the total tumor burden than each molecule alone. To support the in vivo results, we demonstrate in vitro that α-ionone is a real agonist of OR51E2, mainly sustaining LNCaP cell growth, while β-ionone mainly promotes cell invasiveness. So, while structurally close, α-ionone and β-ionone appear to induce different cellular effects, both leading to increased tumor aggressiveness. This behaviour could be explained by a different coupling to downstream effectors, as it has been reported for the so-called biased ligands of other G protein-coupled receptors.
