Project description:We investigated differentially expressed sncRNAs in human sperm as candidate markers for evaluating sperm quality during IVF. We demonstrated that differentially expressed tsRNAs, rsRNAs and miRNAs are linked to sperm quality according to embryo quality, even though these sperm samples were all considered normal by the traditional semen-parameter assessment. Therefore, the sncRNAs, especially tsRNAs and rsRNAs, may be potential clinical biomarkers for the assessment of sperm quality in IVF.

Project description:Prototypical micro RNAs (miRNAs) are 21~25-base-pair RNAs that regulate differentiation, carcinogenesis and pluripotency by eliminating mRNAs or blocking their translation, processes collectively termed RNA interference (RNAi). RNAi mediated by miRNAs regulates early development in zebrafish, and mouse embryos lacking the miRNA precursor processor, Dicer, are inviable. However, the role of miRNAs during mammalian fertilization is unknown. We here show using microarrays that miRNAs are present in mouse sperm structures that enter the oocyte at fertilization. Sperm contained a broad profile of miRNAs and a subset of potential mRNA targets were expressed in fertilizable, metaphase II (mII) oocytes. Oocytes contained transcripts for the RNAinduced silencing complex (RISC) catalytic subunit, EIF2C3 (formerly AGO3). However, levels of sperm-borne miRNA (measured by quantitative PCR) were apparently low relative to those of unfertilized, mII oocytes, and fertilization did not alter the part of the mII oocyte miRNA landscape that included the most abundant sperm-borne miRNAs. Coinjection of mII oocytes with sperm heads plus anti-miRNAs - to suppress miRNA function - did not perturb pronuclear activation or preimplantation development. Contrastingly, we provide evidence that nuclear transfer by microinjection alters the miRNA profile of enucleated oocytes. These data argue that sperm-borne prototypical miRNAs play a limited role, if any, in mammalian fertilization or early preimplantation development. Keywords: miRNA profiling Seven samples were analyzed for the study.

Project description:EVs are known to contain important cargo of biologically active and regulatory molecules including ncRNAs. EVs in seminal plasma, play an important role in sperm functions , including motility and fertilization. However, less is known about the comprehensive profile of spEV ncRNAs in clinical cohort and if these profiles differ by semen quality status. We assessed sperm-free spEV ncRNA profiles from semen samples of male partners receiving IVF treatment. Men were classified into having normal (n = 59, Status 0) or poor (n = 32, Status 1) semen quality based on WHO semen parameter guidelines.

Project description:In this study, we used the iTRAQ proteomics approach to perform proteomic profiling of spermatozoa associated with sperm quality in sturgeons. The results showed 291 and 359 differentially expressed proteins in A. baerii and A. schrenckii, respectively, of which 72 were common to both species and all were upregulated in high quality compared with low quality samples. The differentially expressed proteins were mainly categorized into the generation of precursor metabolites and energy and oxidation, and they were localized to the mitochondria. Three distinguishing pathways, Arginine and proline metabolism, Pyruvate metabolism and the Citrate cycle (TCA cycle) were found to play an important role in energy metabolism, and some substrates could be used in the sperm medium for storage and cryopreservation.

Project description:Sperm cells of seed plants have lost their motility and are transported by the vegetative pollen tube cell for fertilization. The extent to which sperm cells regulate their own transportation is a long-standing debate. By using the novel Arabidopsis double mutant drop1 drop2, we demonstrate here that sperm cells are only passive cargo and that the vegetative tube cell as a vehicle controls the entire journey.

Project description:Sperm small RNAs have emerged as important non-genetic contributors to embryogenesis and offspring health. A subset of sperm small RNAs are thought to be acquired during epididymal transit. However, the transfer of RNAs from the somatic epididymis to the sperm has been questioned, and the identity of the specific small RNAs transferred remains unclear. Here, we employ Cre/Lox genetics to generate germline- and epididymal-specific Dgcr8 conditional knockout mice to investigate the dynamics of sperm microRNAs and their function in the early embryo. Interestingly, sperm from germline specific Dgcr8 knockout males restored the levels of 58 of the 98 (59%) miRNAs that were lost in testicular sperm during epididymal transit. Conversely, sperm from epididymal Dgcr8 knockouts displayed a 5-fold reduction in 25 miRNAs. This substantial loss of epididymal miRNAs in sperm was accompanied by transcriptomic changes in the embryo which was rescued by microinjection of epididymal miRNAs. These findings ultimately demonstrate the acquisition of miRNAs by sperm during epididymal transit and their regulation of post-fertilization embryonic gene expression.

Project description:Semen samples from men after a short ejaculatory abstinence show improved sperm quality and result in increased pregnancy rates, but the underlying mechanisms remain unclear. Herein, we report that ejaculates from short (1–3 hours) compared with long (3–7 days) periods of abstinence showed increases in motile sperm count, sperm vitality, normal sperm morphology, acrosome reaction capacity, total antioxidant capacity, sperm mitochondrial membrane potential, high DNA stainability, and a decrease in the sperm DNA fragmentation index (P < 0.05). Sperm proteomic analysis showed 322 differentially expressed proteins (minimal fold change of ±1.5 or greater and P < 0.05), with 224 up-regulated and 98 down-regulated. These differentially expressed proteins are profoundly involved in specific cellular processes, such as motility and capacitation, oxidative stress, and metabolism. Interestingly, protein trimethyllysine modification was increased, and butyryllysine, propionyllysine, and malonyllysine modifications were decreased in ejaculates from a short versus long abstinence (P < 0.05). Finally, the rates of implantation, clinical pregnancy, and live births from in vitro fertilization treatments were significantly increased in semen samples after a short abstinence. Our study provides preliminary mechanistic insights into improved sperm quality and pregnancy outcomes associated with spermatozoa retrieved after a short ejaculatory abstinence

Project description:The fusion of two terminally differentiated gametes, a sperm and an oocyte, results in the formation of a totipotent zygote, which is the first step in the development of a mammalian embryo. As the embryo progresses from pre- to post-implantation stage, significant structural and transcriptional changes take place within the embryonic lineage to ensure the success of a series of crucial biological events, such as oocyte activation and maternal-to-zygotic transition coordinated with zygotic gene activation, followed by the first cell-fate decision and lineage-specific differentiation, laying the foundation for the subsequent phase of gastrulation. LncRNAs are mostly transcribed by RNA polymerase II and are longer than 200 nts in length. They can interact with multiple molecules, including DNA, RNA, and protein, for regulating transcription, inducing epigenetic and translational modifications. miRNAs control the regulation of mRNAs by targeting it post transcriptionally. The importance of lncRNAs and miRNAs in germ cell development leads to successful fertilization and subsequently towards post fertilization events. The detail contribution of the maternal and paternal ncRNA profile towards fine tuning these events remain to be deciphered. All these motivated us to look into the parental ncRNA profile within mature fertile sperm and oocyte as well as zygote in mouse system, followed by an in-depth analysis to understand their modes of regulation which finetunes fertilization as well as post fertilization events prior to ZGA.

Project description:Background: MicroRNAs(miRNAs) are a class of non-coding small RNAs, which play important roles in many physiological processes by regulating gene expression. Previously studies show that the expression level of total miRNAs increased during the progression of mouse embryonic development, and some miRNAs control the regulatory network in the development progression. Results: In this study,the results showed that the sperm samples with high expression of miR-191 had higher fertilization rate (FR), blastocyst rate (EER) and high-quality embryo rate (HQER). Conclusions: These findings suggest that higher miR-191-5p expression with better human early embryonic development, and indicate that the miR-191-5p could be a potential marker to access the quality of IVF.
