Abstract
The gut microbiota operates at the interface of host-environment interactions to influence human homoeostasis and metabolic networks1-4. Environmental factors that unbalance gut microbial ecosystems can therefore shape physiological and disease-associated responses across somatic tissues5-9. However, the systemic impact of the gut microbiome on the germline-and consequently on the F1 offspring it gives rise to-is unexplored10. Here we show that the gut microbiota act as a key interface between paternal preconception environment and intergenerational health in mice. Perturbations to the gut microbiota of prospective fathers increase the probability of their offspring presenting with low birth weight, severe growth restriction and premature mortality. Transmission of disease risk occurs via the germline and is provoked by pervasive gut microbiome perturbations, including non-absorbable antibiotics or osmotic laxatives, but is rescued by restoring the paternal microbiota before conception. This effect is linked with a dynamic response to induced dysbiosis in the male reproductive system, including impaired leptin signalling, altered testicular metabolite profiles and remapped small RNA payloads in sperm. As a result, dysbiotic fathers trigger an elevated risk of in utero placental insufficiency, revealing a placental origin of mammalian intergenerational effects. Our study defines a regulatory 'gut-germline axis' in males, which is sensitive to environmental exposures and programmes offspring fitness through impacting placenta function.

Abstract
Tumor necrosis factor alpha (TNF-α) is a cytokine that is responsible for many processes associated with immune response and inflammation. It is involved in the development of an antiviral response to many virus infections. This factor was shown to be activated in influenza A virus infection, which enhances production of other cytokines. The overexpression of these cytokines can lead to a cytokine storm. To study the role of TNF-α in the development of pathologies associated with viral infection, we generated a Tnfa knockout mouse strain. We demonstrated that these mice were characterized by a significant increase in the number of viral genomes compared to that in the parental strain, but the amount of live virus did not differ. A histopathology of the lungs in the genetically modified animals was significantly lower in terms of interalveolar septal infiltration. The generated model may be used to further study pathological processes in viral infections.

Abstract
Well-planned strategies are an essential prerequisite for any mutational analysis involving gene targeting. Consideration of the advantages or disadvantages of different methods will aid in the production of a final product that is both technically feasible and versatile. Strategies for gene-targeting experiments in the mouse are discussed, including the rationale behind some of the common elements of gene-targeting vectors, such as homologous DNA and the use of different site-specific recombinases. We detail positive and negative selection as well as screening strategies for homologous recombination events in embryonic stem (ES) cells. For the planning stages of making different types of alleles, we first consider general strategies and then provide details specific to either homologous recombination in ES cells or making alleles by gene editing with CRISPR-Cas in preimplantation embryos. The types of alleles considered are null or knockout alleles, reporter gene knock-in alleles, point mutations, and conditional null alleles.

Abstract
The CryoPreservation Media (CPM) for mouse sperm using raffinose and skim milk have been improved by adding either monothioglycerol (MTG) or l-glutamine to reduce the oxidative damage during sperm freezing and thawing. The CARD-CPM utilizing l-glutamine, but not MTG, has been widely used to meet the rising demand for cryopreservation of genetically modified mice, as the CARD method also improved sperm capacitation and in vitro fertilization (IVF). However, the viability of sperm frozen in the CARD-CPM is highly variable, indicating a room for improvement. To develop a more dependable technique for mouse sperm cryopreservation, we investigate whether combining MTG and l-glutamine in the CPM (MG-CPM) can produce a synergistic impact on sperm thawing and IVF rate. We found that MG-CPM reduced the incidence of infertility and increased the IVF success rate. Therefore, cryopreservation of mouse sperm in MG-CPM is a reliable method to ensure embryo generation from frozen sperm.

Abstract
Background The protein proAKAP4 is crucial for sperm motility and has been suggested as an indicator of male fertility. We determined the relationship between proAKAP4 concentration and sperm motility parameters in mice, and investigated the effects of cryopreservation on these variables. Methods Computer-assisted sperm analysis and ELISA were applied to determine sperm motility and proAKAP4 concentration in fresh and frozen-thawed epididymal sperm of SWISS, B6D2F1, C57BL/6N, and BALB/c mice. Results ProAKAP4 levels ranged between 12 and 89 ng/ml and did not differ between fresh and frozen-thawed samples, or between strains. We found a negative relationship between proAKAP4 levels and some sperm motility parameters. Sperm traits differed between strains, and cryopreservation negatively affected sperm velocity but not sperm direction parameters. Conclusion ProAKAP4 levels in epididymal mouse spermatozoa were unaffected by cryopreservation, highlighting the robustness of this parameter as a potentially time-independent marker for sperm motility and fertility. The high individual variation in proAKAP4 levels supports the potential role of proAKAP4 as a marker for sperm quality, though we found no positive, and even negative relationships between proAKAP4 levels and some sperm motility parameters. Future studies have to investigate the significance of proAKAP4 as an indicator for fertility in mice.

Abstract
Stimulator of interferon genes (STING) contributes to anti-tumor immunity by activating antigen-presenting cells and inducing mobilization of tumor-specific T cells. A role for tumor-migrating neutrophils in the anti-tumor effect of STING-activating therapy has not been defined. We used mouse tumor transplantation models for assessing neutrophil migration into the tumor triggered by intratumoral treatment with STING agonist, 2'3'-cyclic guanosine monophosphate-adenosine monophosphate (cGAMP). Intratumoral STING activation with cGAMP enhanced neutrophil migration into the tumor in an NF-κB/CXCL1/2-dependent manner. Blocking the neutrophil migration by anti-CXCR2 monoclonal antibody impaired T cell activation in tumor-draining lymph nodes (dLNs) and efficacy of intratumoral cGAMP treatment. Moreover, the intratumoral cGAMP treatment did not show any anti-tumor effect in type I interferon (IFN) signal-impaired mice in spite of enhanced neutrophil accumulation in the tumor. These results suggest that both neutrophil migration and type I interferon (IFN) induction by intratumoral cGAMP treatment were critical for T-cell activation of dLNs and the anti-tumor effect. In addition, we also performed in vitro analysis showing enhanced cytotoxicity of neutrophils by IFN-β1. Extrinsic STING activation triggers anti-tumor immune responses by recruiting and activating neutrophils in the tumor via two signaling pathways, CXCL1/2 and type I IFNs.

Abstract
Germplasm cryobanking of transgenic rodent models is a valuable tool for protecting important genotypes from genetic drift, genetic contamination, and loss of breeding colonies due to disease or catastrophic disasters to the housing facilities as well as avoiding stress associated with domestic and international live animal shipment. Furthermore, cryopreservation of germplasm enhances management efficiencies by saving animal room space, reducing workload for staff, reducing cost of maintaining live animals, reducing the number of animals used to maintain a breeding colony, and facilitating transportation of genetics by allowing distribution of frozen germplasm rather than live animals which also reduces the risk of transfer of pathogens between facilities. Thus, effective long-term preservation methods of mouse spermatozoa are critical for future reconstitution of scientifically important mouse strains used for biomedical research.

Cfap97d1 is important for flagellar axoneme maintenance and male mouse fertility. PLoS Genet 2020; 16:e1008954.

Abstract
The flagellum is essential for sperm motility and fertilization in vivo. The axoneme is the main component of the flagella, extending through its entire length. An axoneme is comprised of two central microtubules surrounded by nine doublets, the nexin-dynein regulatory complex, radial spokes, and dynein arms. Failure to properly assemble components of the axoneme in a sperm flagellum, leads to fertility alterations. To understand this process in detail, we have defined the function of an uncharacterized gene, Cfap97 domain containing 1 (Cfap97d1). This gene is evolutionarily conserved in mammals and multiple other species, including Chlamydomonas. We have used two independently generated Cfap97d1 knockout mouse models to study the gene function in vivo. Cfap97d1 is exclusively expressed in testes starting from post-natal day 20 and continuing throughout adulthood. Deletion of the Cfap97d1 gene in both mouse models leads to sperm motility defects (asthenozoospermia) and male subfertility. In vitro fertilization (IVF) of cumulus-intact oocytes with Cfap97d1 deficient sperm yielded few embryos whereas IVF with zona pellucida-free oocytes resulted in embryo numbers comparable to that of the control. Knockout spermatozoa showed abnormal motility characterized by frequent stalling in the anti-hook position. Uniquely, Cfap97d1 loss caused a phenotype associated with axonemal doublet heterogeneity linked with frequent loss of the fourth doublet in the sperm stored in the epididymis. This study demonstrates that Cfap97d1 is required for sperm flagellum ultra-structure maintenance, thereby playing a critical role in sperm function and male fertility in mice.

Abstract
In vitro fertilization (IVF) is an established technology that is widely used in reproductive engineering. However, in rats, successful application of IVF is difficult to achieve, and it has had poor reproducibility. In a previous study on the critical issues associated with successful IVF in Wistar rats, we investigated the influence of oocyte collection duration on fertilization rates by dividing the procedure into three steps (oviduct extraction from euthanized animals, oocyte collection from the ampullae of oviducts, and oocyte preincubation until insemination), and identified the appropriate times for each. Here we show that use of the same defined duration for oviduct extraction from superovulated Wistar rats and for oocyte collection from the oviducts also produced highly reproducible fertilization rates of more than 90% in other rat strains. Furthermore, the versatility of these criteria was demonstrated using another IVF protocol. Thus, this simple procedure has enabled the standardization of IVF in rats and will enhance further experimental studies.

Extracellular Vesicles Derived from Mesenchymal Stem Cells Recover Fertility of Premature Ovarian Insufficiency Mice and the Effects on their Offspring. Cell Transplant 2020; 29:963689720923575. [PMID: 32363925 PMCID: PMC7586265 DOI: 10.1177/0963689720923575] [Citation(s) in RCA: 26] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2020] [Revised: 04/04/2020] [Accepted: 04/09/2020] [Indexed: 12/31/2022] Open
Abstract
It has been reported that extracellular vesicles (EVs) derived from human umbilical cord mesenchymal stem cells (HUCMSCs) can promote the proliferative and secretive functions of granulosa cells. In vivo study further demonstrated that EVs derived from HUCMSCs can not only promote the angiogenesis of ovarian tissue but also restore the function of an ovary of chemically induced premature ovarian insufficiency (POI) mice. However, no study investigates the effects of HUCMSCs derived EVs on fertility recovery of POI mice and evaluating their offspring. This study investigates the effects of HUCMSCs derived EVs on fertility recovery and the cognitive function of their offspring. A POI model was established by intraperitoneal injection of cyclophosphamide (CTX) and busulfan (BUS), and randomly divided into EVs-transplantation group (a single injection of 150 µg EVs proteins which suspended in 0.1 ml phosphate buffer saline [PBS] via tail vein), POI group (a single injection of 0.1 ml PBS via tail vein), and normal control group (a single injection of 0.1 ml PBS via tail vein without intraperitoneal injection of CTX and BUS). After EVs treatment, not only the ovarian function of POI mice recovered but also the fertility increased with less time to get pregnant, evaluating by in vitro fertilization and mating test. Cognitive behaviors of the offspring were similar among the three groups through the Y-maze test and novel object recognition task. An anti-apoptotic effect was identified through immunohistochemistry, real-time polymerase chain reaction and western blot. These findings indicate that HUCMSCs derived EVs can improve the fertility of POI mice without adverse effects on the cognitive behavior of their offspring, highlighting the potential value of EVs to be a cell-free therapy for patients suffering from POI.

Abstract
The clustered regularly interspaced short palindromic repeats (CRISPR)/Cas9 system has facilitated dramatic progress in the field of genome engineering. Whilst microinjection of the Cas9 protein and a single guide RNA (sgRNA) into mouse zygotes is a widespread method for producing genetically engineered mice, in vitro and in vivo electroporation (which are much more convenient strategies) have recently been developed. However, it remains unknown whether these electroporation methods are able to manipulate genomes at the chromosome level. In the present study, we used these techniques to introduce chromosomal inversions of several megabases (Mb) in length in mouse zygotes. Using in vitro electroporation, we successfully introduced a 7.67 Mb inversion, which is longer than any previously reported inversion produced using microinjection-based methods. Additionally, using in vivo electroporation, we also introduced a long chromosomal inversion by targeting an allele in F1 hybrid mice. To our knowledge, the present study is the first report of target-specific chromosomal inversions in mammalian zygotes using electroporation.

Abstract
A substantial number of mouse genes, about 25%, are embryonically lethal when knocked out. Using current genetic tools, such as the CRISPR-Cas9 system, it is difficult-or even impossible-to produce viable mice with heritable embryonically lethal mutations. Here, we establish a one-step method for microinjection of CRISPR reagents into one blastomere of two-cell embryos to generate viable chimeric founder mice with a heritable embryonically lethal mutation, of either Virma or Dpm1. By examining founder mice, we identify a phenotype and role of Virma in regulating kidney metabolism in adult mice. Additionally, we generate knockout mice with a heritable postnatally lethal mutation, of either Slc17a5 or Ctla-4, and study its function in vivo. This one-step method provides a convenient system that rapidly generates knockout mice possessing lethal phenotypes. This allows relatively easy in vivo study of the associated genes' functions.

Abstract
Artificial insemination can be achieved by directly adding sperm from a particular male into the oviduct of a female successfully bred with a vasectomized male by a surgical procedure. Those who are comfortable performing oviduct embryo transfers might find this approach much easier than delivering the sperm into the vagina. Multiple females can be inseminated with sperm from a single male to rescue the line, expand the line quickly, or generate relatively synchronous embryos.

Abstract
In conventional vitrification methods, the embryos are vitrified under considerable supercooling (i.e., under nonequilibrium conditions). This protocol is a refinement of newer equilibrium vitrification methods. The equilibrium vitrification solution contains a high concentration of cryoprotectants that increase its osmolality and allows vitrified embryos to survive not only during storage in liquid nitrogen (LN2) at -196°C but also during temporary holding at -80°C (for at least 5 mo). This high-osmolality vitrification (HOV) method is as simple as conventional vitrification and provides essentially the same high postwarming survival rate. It has several advantages over conventional vitrification: (1) Cryopreserved embryos are less likely to be damaged during handling for warming; (2) samples can be temporarily evacuated to a -80°C freezer and can be successfully recovered after 5 mo at -80°C; (3) samples can be arranged and sorted at -80°C; and (4) vitrified embryos can be transported using dry ice. Also included here is an alternative protocol that describes the use of straws instead of cryotubes.

Abstract
This embryo cryopreservation protocol is used by The Jackson Laboratory and several other repositories around the world. This protocol has clearly withstood the test of time; >2 million embryos from thousands of strains have been cryopreserved using this method. It requires a controlled-rate freezer, but is simple, effective, and can be applied to cryopreserve embryos from the two-cell to the blastocyst stage. Thawing requires neither special media nor equipment because the insemination straw contains all of the needed elements, making this very useful for distributing cryopreserved embryos. Embryo survival rates of greater than 90% can be expected when this method is used, making it reliable and enabling staff with prior embryo-handling experience to become proficient quickly.
