Resumen
Abstract Insulin signaling in the brain plays an important role in the central regulation of energy homeostasis and fertility, such that mice exhibiting brain-specific deletion of insulin receptors (InsRs) display a diet-sensitive obesogenic phenotype and hypothalamic hypogonadism. However, the specific neurons mediating insulin's central effects on fertility remain largely unidentified. The neurotransmitters γ-aminobutyric acid (GABA) and glutamate are important modulators of fertility and energy homeostasis and are widely distributed in the hypothalamus. We therefore investigated whether ins

Nucleotide-binding domain and leucine-rich repeat (NLR) proteins are well-known for their key roles in the immune system. Ectopically expressed NLRP2 in immortalized cell lines assembles an inflammasome and inhibits activation of the proinflammatory transcription factor NF-κB, but the physiological roles of NLRP2 are unknown. Here, we show that Nlrp2-deficient mice were born with expected Mendelian ratios and that Nlrp2 was dispensable for innate and adaptive immunity. The observation that Nlrp2 was exclusively expressed in oocytes led us to explore the role of Nlrp2 in parthenogenetic activat

Mouse zona pellucida protein 3 peptide conjugated to a carrier protein (keyhole limpet hemocyanin) was considerably more immunogenic and effective in reducing fertility in wild mice when compared with inbred BALB/c mice.

The absolute requirement for reproduction implies that the hypothalamo-pituitary-gonadal axis, controlling fertility, is an evolutionary robust mechanism. The GnRH neurons of the hypothalamus represent the key cell type within the body dictating fertility. However, the level of functional redundancy within the GnRH neuron population is unknown. As a result of a fortuitous transgene insertion event, GNR23 mice exhibit a marked allele-dependent reduction in GnRH neuron number within their brain. Wild-type mice have approximately 600 GnRH neurons, compared with approximately 200 (34%) and approxi

Upon adhesion to the zona pellucida, sperm undergo regulated exocytosis of the acrosome. Although it is necessary for sperm to penetrate the zona pellucida and fertilize an egg, the acrosomal membrane fusion process is poorly understood. Complexins I and II are small, cytosolic proteins that bind to a complex of proteins termed the solubleN-ethylmaleimide-sensitive factor attachment protein receptor complex to regulate synaptic vesicle exocytosis.

Mitochondrial ferritin (FtMt) is a functional ferritin targeted to mitochondria that is highly expressed in the testis. To investigate the role of FtMt in the testis we set up a series of controlled matings between FtMt gene-deletion mice (FtMt–/–) with FtMt+/+ mice. We found that the number of newborns per litter and the fertility rate were strongly reduced for the FtMt–/– males, but not for the females, indicating that FtMt has an important role for male fertility. The morphology of the testis and of the spermatozoa of FtMt–/– mice was normal and we did not detect alterations in sperm parame

Type 1 diabetes is associated with subfertility in humans. The current treatment for type 1 diabetes, insulin monotherapy, is suboptimal to fully stabilize glycemia, potentially leading to this subfertility. Recent work has demonstrated that treatment with the energy-regulating hormone leptin, alone or in combination with insulin, can more effectively control glycemia in mouse models of type 1 diabetes. Here, we sought to determine whether the fertility defects in a type 1 diabetic mouse model, the Akita mouse, can be rescued with leptin monotherapy in the absence of any exogenous insulin. Aki

Abstract The hormone leptin is critical for the regulation of energy balance and fertility. The long-form leptin receptor (LepR) regulates multiple intracellular signaling cascades, including the classic Janus kinase-signal transducer and activator of transcription (STAT) pathways.

ABSTRACT LGR7 is a G-protein coupled receptor with structural homology to the gonadotrophin and thyrotrophin receptors. Recently, LGR7 was deorphanized, and it was shown that relaxin is the ligand for LGR7. To further study the function of this receptor, mice deficient for LGR7 were generated by replacing part of the transmembrane-encoding region with a LacZ reporter cassette. Here we show that LGR7 is expressed in various tissues, including the uterus, heart, brain, and testis. Fertility studies using female LGR7−/− mice showed normal fertility and litter size.

Resumen
The reproductive toxicity of trivalent and hexavalent chromium compounds was investigated in male and female mice exposed to 1000 ppm chromium chloride and potassium dichromate via their mother during gestational and lactational periods. Fertility was reduced in male offspring exposed to either trivalent or hexavalent chromium compounds. Body weights and weights of testes, seminal vesicles and preputial glands were reduced in trivalent-exposed male offspring. The exposure of female mice offspring to trivalent and hexavalent chromium compounds delayed sexual maturation. Fertility was reduced in

Resumen
Phospholipase C zeta1 (Plcz1) was known to be a physiological factor in sperm that activates oocytes to complete meiosis by triggering Ca2+ oscillations after fertilisation. However, the role of male Plcz1 in spermatogenesis and early embryo development in progeny has been controversial. Plcz1 knockout (Plcz1−/−) mouse model (Plcz1m3 and Plcz1m5) was generated by using the CRISPR-Cas9 system. The fertility of Plcz1−/− mice was evaluated by analysing the number of offsprings, sperm quality, pathological changes in the testis and epididymis. RNA-seq and RT-PCR were performed to screen differenti

Resumen
ABSTRACT Epidermal growth factor (EGF) levels in the submandibular glands and plasma are increased in pregnant and aged female mice. The possible role of EGF in fertility was studied in virgin and pregnant mice ranging in age from 10 to 90 weeks of age, employing sialoadenectomy, administration of EGF antibody and EGF replacement. The uterine weight in pregnant, 10-week-old, sialoadenectomized mice was significantly less than in normal mice and the administration of EGF antibody to these mice further decreased uterine weight, resulting in an increased rate of abortion. Replacement EGF treatmen

Resumen
The secretory glycoprotein lactoferrin (LF) is suggested to ameliorate overweight regardless of non-genetic or genetic mechanisms. Although maternal overweight represents a key predictor of offspring growth, the efficacy of LF on fertility problems in overweight and obese mothers remains unknown. To address this issue, we examined the effect of LF ingestion by analyzing overweight mice (Institute of Cancer Research (ICR) mice with high-fat diets; HF mice) and obese mice (leptin-deficient mice with type II diabetes; ob/ob mice). Plasma insulin, leptin, glucose, and cholesterol levels were measu

Resumen
In many mammals, genomic sites for recombination are determined by the histone methyltransferase PRMD9. Some mouse strains lacking PRDM9 are infertile, but instances of fertility or semifertility in the absence of PRDM9 have been reported in mice, canines, and a human female. Such findings raise the question of how the loss of PRDM9 is circumvented to maintain fertility. We show that genetic background and sex-specific modifiers can obviate the requirement for PRDM9 in mice. Specifically, the meiotic DNA damage checkpoint protein CHK2 acts as a modifier allowing female-specific fertility in th

Resumen
Superovulation of female mice with exogenous gonadotrophins is routinely used for increasing the number of eggs ovulated by each female in reproductive and developmental studies. We report an unusual effect of superovulation on fertilization in mice.In vivomatings of superovulated T-stock females with B6C3F1 males resulted in a two-fold reduction (P< 0.001) in the frequencies of fertilized eggs compared with control B6C3F1 matings. In addition, approximately 22 h after mating, only 15% of fertilized eggs recovered in T-stock females had reached the metaphase stage of the first cleavage divi
