Abstract
Antipsychotic drugs are the mainstay of treatment for schizophrenia and provide adjunct therapies for other prevalent psychiatric conditions, including bipolar disorder and major depressive disorder. However, they also induce debilitating extrapyramidal syndromes (EPS), such as Parkinsonism, in a significant minority of patients. The majority of antipsychotic drugs function as dopamine receptor antagonists in the brain while the most recent 'third'-generation, such as aripiprazole, act as partial agonists. Despite showing good clinical efficacy, these newer agents are still associated with EPS in ~ 5 to 15% of patients. However, it is not fully understood how these movement disorders develop. Here, we combine clinically-relevant drug concentrations with mutliscale model systems to show that aripiprazole and its primary active metabolite induce mitochondrial toxicity inducing robust declines in cellular ATP and viability. Aripiprazole, brexpiprazole and cariprazine were shown to directly inhibit respiratory complex I through its ubiquinone-binding channel. Importantly, all three drugs induced mitochondrial toxicity in primary embryonic mouse neurons, with greater bioenergetic inhibition in ventral midbrain neurons than forebrain neurons. Finally, chronic feeding with aripiprazole resulted in structural damage to mitochondria in the brain and thoracic muscle of adult Drosophila melanogaster consistent with locomotor dysfunction. Taken together, we show that antipsychotic drugs acting as partial dopamine receptor agonists exhibit off-target mitochondrial liabilities targeting complex I.

Abstract
Purpose Uveal coloboma is a congenital eye malformation caused by failure of the optic fissure to close in early human development. Despite significant progress in identifying genes whose regulation is important for executing this closure, mutations are detected in a minority of cases using known gene panels, implying additional genetic complexity. We have previously shown knockdown of znf503 (the ortholog of mouse Zfp503) in zebrafish causes coloboma. Here we characterize Zfp503 knockout (KO) mice and evaluate transcriptomic profiling of mutant versus wild-type (WT) retinal pigment epithelium (RPE)/choroid. Methods Zfp503 KO mice were generated by gene targeting using homologous recombination. Embryos were characterized grossly and histologically. Patterns and level of developmentally relevant proteins/genes were examined with immunostaining/in situ hybridization. The transcriptomic profile of E11.5 KO RPE/choroid was compared to that of WT. Results Zfp503 is dynamically expressed in developing mouse eyes, and loss of its expression results in uveal coloboma. KO embryos exhibit altered mRNA levels and expression patterns of several key transcription factors involved in eye development, including Otx2, Mitf, Pax6, Pax2, Vax1, and Vax2, resulting in a failure to maintain the presumptive RPE, as evidenced by reduced melanin pigmentation and its differentiation into a neural retina-like lineage. Comparison of RNA sequencing data from WT and KO E11.5 embryos demonstrated reduced expression of melanin-related genes and significant overlap with genes known to be dynamically regulated at the optic fissure. Conclusions These results demonstrate a critical role of Zfp503 in maintaining RPE fate and optic fissure closure.

Abstract
In Parkinson’s disease (PD), substantia nigra (SN) dopaminergic (DA) neurons degenerate, while related ventral tegmental area (VTA) DA neurons remain relatively unaffected. Here, we present a methodology that directs the differentiation of mouse and human pluripotent stem cells toward either SN- or VTA-like DA lineage and models their distinct vulnerabilities. We show that the level of WNT activity is critical for the induction of the SN- and VTA-lineage transcription factors Sox6 and Otx2, respectively. Both WNT signaling modulation and forced expression of these transcription factors can drive DA neurons toward the SN- or VTA-like fate. Importantly, the SN-like lineage enriched DA cultures recapitulate the selective sensitivity to mitochondrial toxins as observed in PD, while VTA-like neuron-enriched cultures are more resistant. Furthermore, a proteomics approach led to the identification of compounds that alter SN neuronal survival, demonstrating the utility of our strategy for disease modeling and drug discovery. Derivation of distinct dopaminergic subpopulations from pluripotent stem cells Wnt signaling inhibitors promote SN dopaminergic neuron specification Modeling selective vulnerability of SN dopaminergic neurons in vitro Proteomics reveals pathways that promote SN dopaminergic neuron survival

Abstract
Midbrain dopaminergic (DA) axons make long longitudinal projections towards the striatum. Despite the importance of DA striatal innervation, processes involved in establishment of DA axonal connectivity remain largely unknown. Here we demonstrate a striatal-specific requirement of transcriptional regulator Nolz1 in establishing DA circuitry formation. DA projections are misguided and fail to innervate the striatum in both constitutive and striatal-specific Nolz1 mutant embryos. The lack of striatal Nolz1 expression results in nigral to pallidal lineage conversion of striatal projection neuron subtypes. This lineage switch alters the composition of secreted factors influencing DA axonal tract formation and renders the striatum non-permissive for dopaminergic and other forebrain tracts. Furthermore, transcriptomic analysis of wild-type and Nolz1−/− mutant striatal tissue led to the identification of several secreted factors that underlie the observed guidance defects and proteins that promote DA axonal outgrowth. Together, our data demonstrate the involvement of the striatum in orchestrating dopaminergic circuitry formation. The mechanisms regulating midbrain dopaminergic innervation during development are unclear. Here, the authors showed that Nolz1 is required for axonal guidance of dopaminergic neurons during embryonic development of the mouse brain.

Abstract
Sperm proteomes have emerged for several species; however, the extent of species similarity is unknown. Sheep are an important agricultural species for which a comprehensive sperm proteome has not been produced. In addition, potential proteomic factors from seminal plasma that may contribute to improved fertility after cervical insemination are yet to be explored. Here we use liquid chromatography-tandem mass spectrometry to investigate the proteome of ejaculated ram spermatozoa, with quantitative comparison to epididymal spermatozoa. We also present a comparison to published proteomes of five other species. We identified 685 proteins in ejaculated ram spermatozoa, with the most abundant proteins involved in metabolic pathways. Only 5% of ram sperm proteins were not detected in other species, which suggest highly conserved structures and pathways. Of the proteins present in both epididymal and ejaculated ram spermatozoa, 7% were more abundant in ejaculated spermatozoa. Only two membrane-bound proteins were detected solely in ejaculated sperm lysates: liver enriched gene 1 (LEG1/C6orf58) and epidermal growth factor-like repeats and discoidin I-like domains 3 (EDIL3). This is the first evidence that despite its relatively complex proteomic composition, seminal plasma exposure leads to few novel proteins binding tightly to the ram sperm plasma membrane.

Abstract
Successful pregnancy requires an appropriate communication between the mother and the embryo(s). Recent studies indicate that exosomes, small (30–100 nm) membrane-bound vesicles of endocytotic origin, could act as intercellular vehicles in this unique communication system in the uterus. However, little is known about the role of these vesicles in the oviduct. Our study aimed at (1) demonstrating the existence of oviducal-embryo communication via exosomes, (2) deciphering the exosomal dialogue between them at the proteomic level, and (3) comparing the exosomal proteomic content to the oviducal fluid proteomic content in order to highlight the key role of exosomes in this dialogue. Cow oviducts (pool of 6 oviducts at different stages of the cycle in 4 replicates) were flushed, and exosomes were isolated by serial ultracentrifugation. Exosomes were measured by dynamic light scattering analysis, resulting in exosomes (63.25–97.03 nm) and microvesicle observations (>100 nm). Bovine embryos were produced in vitro up to the blastocyst and hatching/hatched blastocyst stages. To demonstrate the existence of the oviducal-embryo communication via exosomes, oviducal exosomes were labelled with green fluorescent dye (PKH67), filtered (0.22 µm) to remove microvesicles, and co-incubated with blastocysts and hatching/hatched (H) blastocysts for 20 h, under 5% CO2 and 5% O2 conditions. Subsequently, embryos were washed in exosome-free medium, fixed in 4% paraformaldehyde, and labelled with Hoechst 33342 and Actin Red Phallodin. Confocal microscopy observations confirmed that exosomes were internalized by blastocysts and H-blastocysts and located around the nucleus, demonstrating the existence of an oviducal-embryo communication via exosomes. Moreover, our results showed that the zona pellucida does not represent a barrier for exosomes and they act as natural nanoshuttles bringing oviducal signals into the embryo. Then, proteomic analysis by LC1D-nanoESI-LTQ-Orbitrap was used to decipher oviducal exosomal content, identifying 480 proteins. Gene ontology analysis revealed that a high number of these proteins were involved in metabolism (24.9%), cellular process (19.3%), and 0.8% reproductive processes. Further analysis revealed that more than 56% of exosomal proteins involved in cellular process were associated with cell-to-cell communication. Finally, exosomal proteins were compared with proteins present in oviducal fluid from a pool of samples from cows at Day 0 and Day 10 of the oestrous cycle. Comparative analysis showed that from a total of 607 proteins identified in both oviducal exosomes and fluid sources, 105 were specific to exosomes, 127 were specific to fluid, whereas 375 were common to both sources. Our findings provide the first evidence of oviducal-embryo communication via exosomes, an important first step in furthering the understanding of the oviducal environment and the role of exosomes as early mediators of embryo-maternal cross talk.

Abstract
The female genital tract includes several anatomical regions whose luminal fluids successively interact with gametes and embryos and are involved in the fertilisation and development processes. The luminal fluids from the inner cervix, the uterus and the oviduct were collected along the oestrous cycle at oestrus (Day 0 of the cycle) and during the luteal phase (Day 10) from adult cyclic ewes. The proteomes were assessed by GeLC-MS/MS and quantified by spectral counting. A set of 940 proteins were identified including 291 proteins differentially present along the cycle in one or several regions. The global analysis of the fluid proteomes revealed a general pattern of endocrine regulation of the tract, with the cervix and the oviduct showing an increased differential proteins abundance mainly at oestrus while the uterus showed an increased abundance mainly during the luteal phase. The proteins more abundant at oestrus included several families such as the heat shock proteins (HSP), the mucins, the complement cascade proteins and several redox enzymes. Other proteins known for their interaction with gametes such as oviductin (OVGP), osteopontin, HSPA8, and the spermadhesin AWN were also overexpressed at oestrus. The proteins more abundant during the luteal phase were associated with the immune system such as ceruloplasmin, lactoferrin, DMBT1, or PIGR, and also with tissue remodeling such as galectin 3 binding protein, alkaline phosphatase, CD9, or fibulin. Several proteins differentially abundant between estrus and the luteal phase, such as myosin 9 and fibronectin, were also validated by immunohistochemistry. The potential roles in sperm transit and uterine receptivity of the proteins differentially regulated along the cycle in the female genital tract are discussed.

Abstract
The fertility after use of liquid stored ram semen following cervical AI rapidly decreases if semen is stored beyond 12h. The dilution of seminal plasma is often cited as a key contributor to the diminished motility and fertility of ram spermatozoa subjected to liquid preservation. Two experiments were conducted to assess the effect of spermatozoa concentration (i.e. dilution rate) and percentage of seminal plasma on the motility and viability of liquid stored ram spermatozoa. In Experiment 1, semen was diluted to one of seven concentrations ranging from 0.2 to 1.4×10(9)spermatozoa/ml with milk and assessed for motility after 3 or 24h of storage at 15°C. In Experiment 2, semen was collected and washed to remove seminal plasma before re-dilution to 0.2-1.4×10(9)spermatozoa/ml with milk containing 0%, 20% or 40% (final v/v ratio) seminal plasma and assessed for viability and motility after 3 or 24h of storage at 15°C. Whereas motility was not affected by spermatozoa concentration after 3h of storage, the proportion of progressive spermatozoa decreased after 24h of storage when spermatozoa concentration was greater than 1.0×10(9)spermatozoa/ml. The duration of preservation and the spermatozoa concentration affected spermatozoa motility but had no impact on spermatozoa viability. This negative effect of greater spermatozoa concentrations on motility was independent of the presence and the concentration of seminal plasma. The seminal plasma at both concentrations (20% and 40%) had a protective effect on spermatozoa motility after 24h of storage. These findings have the potential to improve the efficiency of cervical AI with liquid stored ram semen.

Abstract
Successful pregnancy requires an appropriate communication between the mother and the embryo(s). Recent studies indicate that exosomes, small (30–200 nm) membrane vesicles of endocytotic origin, could act as intercellular vehicles in this unique communication system. Exosomes have been identified in vivo in all body fluids including follicular, uterine, and oviductal fluids and can be secreted by most cell types in vitro. Bovine oviductal epithelial cells (BOEC) have been thoroughly used to study embryo-maternal communication and to improve embryo development in vitro. Hence, our objective was to provide a morphologic and proteomic characterisation of exosomes secreted by BOEC in vivo in the oviductal fluid and in vitro in the conditioned media. Oviducts from cows were flushed to recover in vivo exosomes and then BOEC were scraped in order to derive primary cultures. In vitro exosomes were collected from conditioned media of BOEC primary cultures after reaching confluence (10 days). Isolation of exosomes from in vivo and in vitro origin was performed by ultracentrifugation. The presence of exosomes was confirmed in oviductal flushings and conditioned media by electron microscopy. Further characterisation of exosomes was carried out based on morphology (transmission electron microscopy), size (dynamic light scattering, DLS), and protein composition (protein profile analysis by SDS-PAGE and Western immunoblotting). Preliminary results by DLS revealed different size distribution profiles in exosome samples (in vivo: mean size of 93.41 nm; in vitro: 433.5 nm). Because exosomes are considered as “micromaps” of the originating cells, protein patterns expressed by in vivo exosomes and in vitro exosomes were compared with scraped and cultured BOEC, respectively. Protein profile analysis by SDS-PAGE showed quantitative and qualitative differences among the exosome samples, their cells of origin, and the milieu (conditioned media or flushing). Exosome-specific protein bands were detected and will be further characterised. In addition, exosomes from in vivo and in vitro origin exhibited distinct proteomic profiles. Western blot analysis demonstrated that (1) both exosomal protein samples were positive for HSP70, a known exosomal protein, and negative for Grp78, an endoplasmic reticulum marker detected in BOEC; (2) in vivo exosomes expressed oviductal glycoprotein (OVGP), heat shock protein A8 (HSPA8), and myosin 9 (MYH9), 3 oviductal proteins with known roles in fertilization and early pregnancy. However, only HSPA8 and MYH9 were detected in in vitro exosomes. Our results provide the first extensive characterisation of oviductal exosomes from in vivo and in vitro origin, an essential step in furthering our understanding of the early embryo-maternal cross talk.

Abstract
Seminal plasma purportedly plays a critical role in reproduction, but epididymal spermatozoa are capable of fertilisation following deposition in the uterus, calling into question the biological requirement of this substance. Through a combination of direct observation of spermatozoa in utero using probe-based Confocal Laser Endomicroscopy, in vivo assessment of sperm fertility and in vitro analysis of various sperm functional parameters, this study investigated the role of seminal plasma in spermatozoa transit through the cervix of the ewe. Following deposition in the cervical os, epididymal spermatozoa previously exposed to seminal plasma displayed an enhanced ability to traverse the cervix as evidenced by both significantly higher pregnancy rates and numbers of spermatozoa observed at the utero-tubal junction when compared with epididymal spermatozoa not previously exposed to seminal plasma. The beneficial effect of seminal plasma on sperm transport was clearly localised to transit through the cervix as pregnancy rates of spermatozoa deposited directly into the uterus were unaffected by exposure to seminal plasma. This phenomenon was not explained by changes to sperm motion characteristics, as seminal plasma had no effect on the motility, kinematic parameters or mitochondrial membrane potential of spermatozoa. Rather, in vitro testing revealed that seminal plasma improved the ability of epididymal spermatozoa to penetrate cervical mucus recovered from ewes in oestrus. These results demonstrate that the survival and transport of ram spermatozoa through the cervix of the ewe is not linked to their motility or velocity but rather the presence of some cervical penetration trait conferred by exposure to seminal plasma.

Abstract
To present results from a two year prospective study on diet, 6 months before and 18 months after retirement. The studied population exhibited an increase in social and physical activities over time after retirement. A significant decrease in weight was found in men 18 months after retirement. Retired individuals reported taking more time for breakfast. 45.5% of retired individuals, compared to 25.5% before retirement, took more than 30 minutes for lunch than before retirement. The amount of dietary nutrients consumed remained the same before and after retirement. However, retired individuals ate out more often, and had guests more frequently. Nutrients' distribution is similar before and after retirement. Given a life expectancy of more than 20 years after retirement, it is necessary to initiate nutritional intervention.
