The challenge remains when evaluating RNA quality in samples with high RNA fragmentation. For example, programmed fragmentation and cytoplasmic expulsion, integral to sperm maturation, is a prime example of the complexities of interpreting RNA-seq data, given that fragmentation can be random andor targeted. To meet this challenge, we developed an algorithm that accurately measures RNA quality in samples with high fragmentation, such as spermatozoa. The integrity of 1,000 previously identified abundant sperm transcripts were independently visualized and evaluated using the Transcript Integrity Index (TII) algorithm to identify intact transcripts. Full-length transcripts from visual and the TII algorithm were evaluated for testis preference in humans using the GTEx tissues database. Samples were then filtered by the Interquartile Range (IQR), identifying those in which the greatest number of transcripts failed to pass the visual or TII thresholds. Transcript lists were overlapped, forming the set of intact transcripts used as TII standards. Each sample was re-evaluated as a function of this TII set of intact transcripts, with poor quality samples identified as those failing in the largest number of transcripts. While ontologically enriched in roles related to spermatogenesis and/or fertilization, samples did not segregate based on birth outcome. The TII algorithm proved an effective means to identify samples of similar quality from sperm, a cell type enriched in biologically fragmented RNAs. The algorithm should facilitate other studies using samples compromised by high levels of RNA fragmentation, such as Formalin-Fixed Paraffin-Embedded samples. Requisite to assessing male health, TII provides a solution to the long-sought-after standard that identifies samples of similar quality.","PeriodicalId":22184,"journal":{"name":"Systems Biology in Reproductive Medicine","volume":"68 1","pages":"258 - 271"},"PeriodicalIF":2.4,"publicationDate":"2022-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49290828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using an <i>in vivo</i> model, Cd-induced damage to the spermatogenesis microenvironment and the protective effects of AsIV were studied. Eighteen male Sprague Dawley (SD) rats were randomly divided into three groups (n = 6/group): Cd group, Cd&AsIV group, and control group. Cd was administered to the rats in the Cd group via i.p. at 1 mg/kg body weight once daily, Cd and AsIV was administered to the rats in the Cd&AsIV group via i.p. at 1 mg/kg body weight and 10 mg/kg body weight respectively once daily, and the same volume of saline was administered to the rats in control group via i.p. once daily. The rats in the three groups were injected continuously for 5 days. Vesicular formation in the seminiferous tubules was observed in the Cd treatment group. The average optical density of claudin-11, zonal occludin-1 (ZO-1), and connexin 43 (Cx43) decreased significantly in the Cd treatment group. The ultrastructural damage of the Sertoli cells and tight junctions were also observed by electron microscopy. AsIV treatment rescued the morphologic changes of the seminiferous tubules of the testis and the ultrastructural damage of the Sertoli cells and tight junctions. The average optical density of claudin-11, ZO-1, and Cx43 also increased significantly after AsIV treatment.

We identified a total of 1687 proteins in stallion seminal plasma, of which 1627 and 1496 proteins were expressed in high- (HM) and low- motile (LM) sperm of stallions, respectively. A total number of 1436 proteins were co-expressed in both the groups; 191 (11%) and 60 (3.5%) proteins were exclusively detected in HM and LM groups, respectively. A total of 220 proteins were upregulated (>1-fold change) and 386 proteins were downregulated in SP from LM group stallions as compared to HM group stallions, while 830 proteins were neutrally expressed in both the groups.

High abundance of peroxiredoxins and low abundance of seminal Chaperonin Containing TCP1 Complex (CCT) complex and Annexins indicate dysregulated oxidative metabolism, which might be the underlying etiology for poor sperm motility in LM group stallions.

At the pronuclear stage, somatic nucleus-transplanted oocytes treated with 5 µM SAHA presented higher histone acetylation at H3K9, H3K14, H4K16 and H4K12, compared to untreated clones (p < 0.05). At the morula stage, cloned embryos treated with 5 μM RG108 or 5 μM SAHA presented lower DNA methylation intensity compared to untreated clones (p < 0.05), resembling the intensity levels of fertilized embryos. However, these effects were not observed when RG108 and SAHA were used in combination. The rate of morula formation was significantly higher in cloned embryos treated with 5 µM SAHA than in untreated clones, whereas treatment with RG108 resulted in no obvious effects on morula formation rates. On the other hand, the combined treatment with RG108 and SAHA resulted in inferior rates of cloned morula formation, compared to untreated clones. At the blastocyst stage, the aberrant expression levels of key developmental genes Oct4 and Cdx2, but not Nanog, were corrected in cloned embryos by the treatment with RG108. This is similar to the intensity levels seen in fertilized embryos. The expression of Rpl7l1 gene was significantly higher in embryos treated with both RG108 and SAHA than in untreated and in control groups.

Despite the achievements in this field, a mounting body of evidence concerning the epigenetic risks associated with ART interventions such as ovarian hormonal stimulation, intracytoplasmic sperm injection (ICSI), and in vitro culture (IVC) of oocytes and embryos has also emerged. Induced development of multiple follicles, the IVC media itself, and extended culture may alter the epigenome of both gametes and embryos, resulting in yet to be fully understood developmental, postnatal, and adult life health consequences. Investigators have attempted to decipher the molecular mechanisms mediating ART-induced epigenetic changes using either human samples or animal models with some success. As research in this field continues to expand, the ethical responsibilities of embryologists and researchers have become critically important. Here, we briefly discuss the ethical aspects of ART research, concentrating on the constraints arising from the perceived 'unnaturalness' of many of these procedures. Secondly, we focus on the bioethics and morality of human embryo research in general and how ethically acceptable model systems may be used to mimic early human embryogenesis. Lastly, we review the 14-day culture limit of human embryos and the notion that this rule could be considered of taken into account using new technologies and cues from animal models. The ‘black box’ of early post-implantation embryogenesis might be revealed using embryo models. As long as this distinct moral line has been drawn and closely followed, we should not fear scientific growth in embryo research. Although in vitro fertilization (IVF) is ethically acceptable, research with human embryos to improve its success raises serious ethical concerns that are in need of constant revisiting.

Young adult male Wistar rats were intraperitoneally injected busulfan (4 mg/kg b.w), and then orally administered rutin (30 mg/kg b.w), and kolaviron (50 mg/kg b.w) alone and combined for 60 days. Results revealed that rutin and kolaviron alone or in combination reversed busulfan-induced increase in oxidative stress along with sperm quality of treated animals. However, kolaviron and rutin separately improved the concentrations of MDA and GSH and sperm quality more than when they were combined. Similarly, rutin and kolaviron separately or in combination preserved spermatogenesis and relieved busulfan-induced increase in nitric oxide concentration, myeloperoxidase and 3β-hydroxysteroid dehydrogenase activities. Co-supplementation with kolaviron but not rutin nor when rutin was combined with kolaviron also improved the testicular level of tumor necrosis-alpha. Finally, the histological features in the testes caused by busulfan were reversed by rutin, whereas treatment with kolaviron alone or in combination with rutin partially protected the testis from busulfan-induced injury as demonstrated by the appearance of few germ cells, damaged tubules, loss of round spermatids and defoliation of the seminiferous epithelium.
