Abstract
Genetic and epigenetic changes in sperm caused by male aging may be essential factors affecting semen parameters, but the effects and specific molecular mechanisms of aging on male reproduction have not been fully clarified. In this study, to explore the effect of aging on male fertility and seek the potential molecular etiology, we performed high-throughput RNA-sequencing in isolated spermatogenic cells, including pachytene spermatocytes (marked by the completion of chromosome synapsis) and round spermatids (produced by the separation of sister chromatids) from the elderly and the young men. Functional enrichment analysis of differentially expressed genes (DEGs) in round spermatids between the elderly and young showed that they were significantly enriched in gamete generation, spindle assembly, and cilium movement involved in cell motility. In addition, the expression levels of DEGs in round spermatids (post-meiotic cells) were found to be more susceptible to age. Furthermore, ten genes (AURKA, CCNB1, CDC20, CCNB2, KIF2C, KIAA0101, NR5A1, PLK1, PTTG1, RAD51AP1) were identified to be the hub genes involved in the regulation of sperm quality in the elderly through Protein-Protein Interaction (PPI) network construction and measuring semantic among GO terms and gene products. Our data provide aging-related molecular alterations in meiotic and post-meiotic spermatogenic cells, and the information gained from this study may explain the abnormal aging-related male fertility decline.

Abstract
Ovarian infertility and subfertility presenting with premature ovarian insufficiency (POI) and diminished ovarian reserve are major issues facing the developed world due to the trend of delaying childbirth. Ovarian senescence and POI represent a continuum of physiological/pathophysiological changes in ovarian follicle functions. Based on advances in whole exome sequencing, evaluation of gene copy variants, together with family-based and genome-wide association studies, we discussed genes responsible for POI and ovarian senescence. We used a gene-centric approach to sort out literature deposited in the Ovarian Kaleidoscope database (http://okdb.appliedbioinfo.net) by sub-categorizing candidate genes as ligand-receptor signaling, meiosis and DNA repair, transcriptional factors, RNA metabolism, enzymes, and others. We discussed individual gene mutations found in POI patients and verification of gene functions in gene-deleted model organisms. Decreased expression of some of the POI genes could be responsible for ovarian senescence, especially those essential for DNA repair, meiosis and mitochondrial functions. We propose to set up a candidate gene panel for targeted sequencing in POI patients together with studies on mitochondria-associated genes in middle-aged subfertile patients.

Abstract
Shugoshin-like protein 1 (SGO1) participated in the proper progression of mitosis. This fundamental role has indicated the importance of this gene in the pathogenesis of cancer as a disorder of mitotic cell division. A previous high throughput study of long non-coding RNAs (lncRNAs) expression in lung cancer has identified aberrant expression of SGO1-antisense 1 (SGO1-AS1) in these specimens. In the current study, we quantified expression of SGO1 and SGO1-AS1 in 39 breast cancer tissues and their paired adjacent non-cancerous tissues (ANCTs). Expression of SGO1-AS1 was considerably decreased in tumoral tissues compared with ANCTs (expression ratio = 0.49, P value = 0.03). However, we could not identify significant difference in expression of SGO1 between these two sets of specimens (expression ratio = 2.9, P value = 0.2). Transcript quantities of SGO1-AS1 were associated with age at disease onset (P= 0.01). Expression of either gene was associated with hormone receptors status or clinical features such as grade and stage. There was an inverse correlation between expressions of genes in both sets of samples. Finally, transcript amounts of SGO1-AS1 could distinguish these two sets of samples with accuracy of 63% (P value = 0.03). Our results imply significance of SGO1-AS1 in breast cancer and necessitate conduction of mechanistic studies to find the molecular pathways in this regard.

Abstract
Objective Oocyte-sperm interaction is the essential step in fertilization. Juno, which
has been known as Folate receptor 4, is the Izumo1 receptor expressed on the
oocyte membrane. This study aims to investigate the location and expression
of Juno in mice oocytes during maturation. Methods To confirm the stage at which Juno expression begins in the mice oocytes and
its location pattern, we performed immunostaining methods. Next, we
evaluated Juno mRNA expression by a half quantitative RT-PCR. Juno knockdown
oocytes were generated by microinjecting siRNA into the germinal vesicle
(GV) stage oocytes, and analyzed the maturation rate. Results Our results showed that Juno was expressed on the surface of the oocyte
cytoplasmic membrane at the GV stage and it continues to be expressed at
similar levels in the metaphase II (MII) stages of oocytes maturation.
Interestingly, Juno is also expressed on the first polar body membrane at
the MII stage. Fluorescence showing Juno expression was decreased in the
oolemma of siRNA injected oocytes, but it was not completely disappearing in
knock down oocytes. MII stage-rates of siRNA injected oocytes were not
significantly different from sham controls. Conclusion Juno was expressed in oocytes at the GV stage and it continues to be
expressed at similar levels in later stages of oocytes maturation. Juno
accumulation in oolemma during oocyte maturation is essential for
fertilization, such as membrane recognition of both gametes.

Abstract
BACKGROUND The kinesin motor protein family consists of 14 distinct subclasses and 45 kinesin proteins in humans. A large number of these proteins, or their orthologues, have been shown to possess essential function(s) in both the mitotic and the meiotic cell cycle. Kinesins have important roles in chromosome separation, microtubule dynamics, spindle formation, cytokinesis and cell cycle progression. This article contains a review of the literature with respect to the role of kinesin motor proteins in female meiosis in model species. Throughout, we discuss the function of each class of kinesin proteins during oocyte meiosis, and where such data are not available their role in mitosis is considered. Finally, the review highlights the potential clinical importance of this family of proteins for human oocyte quality. OBJECTIVE AND RATIONALE To examine the role of kinesin motor proteins in oocyte meiosis. SEARCH METHODS A search was performed on the Pubmed database for journal articles published between January 1970 and February 2017. Search terms included 'oocyte kinesin' and 'meiosis kinesin' in addition to individual kinesin names with the terms oocyte or meiosis. OUTCOMES Within human cells 45 kinesin motor proteins have been discovered, with the role of only 13 of these proteins, or their orthologues, investigated in female meiosis. Furthermore, of these kinesins only half have been examined in mammalian oocytes, despite alterations occurring in gene transcripts or protein expression with maternal ageing, cryopreservation or behavioral conditions, such as binge drinking, for many of them. WIDER IMPLICATIONS Kinesin motor proteins have distinct and important roles throughout oocyte meiosis in many non-mammalian model species. However, the functions these proteins have in mammalian meiosis, particularly in humans, are less clear owing to lack of research. This review brings to light the need for more experimental investigation of kinesin motor proteins, particularly those associated with maternal ageing, cryopreservation or exposure to environmental toxicants.

Abstract
Aneuploidy is the leading genetic abnormality that leads to miscarriage, and it is caused by a failure of accurate chromosome segregation during gametogenesis or early embryonic divisions. Aurora kinase C (AURKC) is essential for formation of euploid sperm in humans because mutations in AURKC are correlated with macrozoospermia and these sperm are tetraploid. These mutations are currently the most frequent mutations that cause macrozoospermia and result from an inability to complete meiosis I (MI). Three of these mutations AURKC c.144delC (AURKC p.L49Wfs22), AURKC c.686G > A (AURKC p.C229Y) and AURKC c.744C > G (AURKC p.Y248*) occur in the coding region of the gene and are the focus of this study. By expressing these alleles in oocytes isolated from Aurkc-/- mice, we show that the mutations have different effects on AURKC function during MI. AURKC p.L49Wfs22 is a loss-of-function mutant that perturbs localization of the chromosomal passenger complex (CPC), AURKC p.C229Y is a hypomorph that cannot fully support cell-cycle progression, and AURKC p.Y248* fails to localize and function with the CPC to support chromosome segregation yet retains catalytic activity in the cytoplasm. Finally, we show that these variants of AURKC cause meiotic failure and polyploidy due to a failure in AURKC-CPC function that results in metaphase chromosome misalignment. This study is the first to assess the function of mutant alleles of AURKC that affect human fertility in a mammalian meiotic system.

Abstract
The ability of human metaphase-II arrested eggs to activate following fertilisation declines with advancing maternal age. Egg activation is triggered by repetitive increases in intracellular Ca2+ concentration ([Ca2+]i) in the ooplasm as a result of sperm-egg fusion. We therefore hypothesised that eggs from older females feature a reduced ability to mount appropriate Ca2+ responses at fertilisation. To test this hypothesis we performed the first examination of Ca2+ dynamics in eggs from young and naturally-aged mice. Strikingly, we find that Ca2+ stores and resting [Ca2+]i are unchanged with age. Although eggs from aged mice feature a reduced ability to replenish intracellular Ca2+ stores following depletion, this difference had no effect on the duration, number, or amplitude of Ca2+ oscillations following intracytoplasmic sperm injection or expression of phospholipase C zeta. In contrast, we describe a substantial reduction in the frequency and duration of oscillations in aged eggs upon parthenogenetic activation with SrCl2. We conclude that the ability to mount and respond to an appropriate Ca2+ signal at fertilisation is largely unchanged by advancing maternal age, but subtle changes in Ca2+ handling occur that may have more substantial impacts upon commonly used means of parthenogenetic activation.
