Abstract
The aim of this study was to assess the usefulness of nanowater (NW; water declusterized using cold plasma treatment) as a diluent for a commercial boar semen extender during the 15-day storage (Days 1 to 15) at 16-18 °C. Ejaculates collected from 8 boars were subjected to the standard evaluation and then diluted in the extender prepared with deionized water (DW) or NW to a final concentration of 3×109 spermatozoa/ml. The proportion of defective spermatozoa increased (P<0.05) from Day 10 to Day 15 of storage (22.8±16.6% to 41.8±26.4% in DW group and 18.6±11.7% to 34.8±25.4% in NW group) and it was significantly greater in DW group compared with NW group on Days 5 and 10 due mainly to a greater (P<0.05) number of mid-piece defects in semen stored in the DW-containing extender. Sperm progressive motility decreased (P<0.05) in both groups between Days 2 and 6, Days 6 and 10, and Days 10 and 12, whereas the percentage of motile spermatozoa declined (P<0.05) to Day 14 only in NW group. Sperm motility was greater (P<0.05) in NW group compared with DW group from Day 5 to Day 13. A decline in sperm progressive motility below 40% in all semen samples occurred by Day 11 in DW group and by Day 12 in NW group. The mean survival time of sperm at 37 °C ex situ was greater in NW group than in DW group on Day 5 (314±87 min compared with 284±87 min) and Day 10 (223±34 min compared with 182±27 min; NW group compared with DW group, respectively). There were no differences (P>0.05) between the two groups in the concentrations of alkaline phosphatase and aspartate aminotransferase in semen extender. To summarize, the use of NW as an extender diluent exerts cytoprotective effects on boar spermatozoa and delays a decline in sperm progressive motility.

Abstract
T-2 toxin is an unavoidable contaminant in human food, animal feeds, and agricultural products. T-2 toxin has been found to impair male reproductive function. But, few data is available that reveals the reproductive toxicity mechanism. In the study, male Kunming mice were orally administrated with T-2 toxin at the doses of 0, 0.5, 1 or 2 mg/kg body weight for 28 days. The body and reproductive organs weight, the concentration, malformation rate and ultrastructure of sperm in cauda epididymis were detected. Oxidative stress biomarkers and apoptosis were also measured in testes. Histological change of testes was performed by H&E and TUNEL staining. T-2 toxin down-regulated body and reproductive organs (testis, epididymis and seminal vesicle) weight, sperm concentration, increased sperm malformation rate and damaged the ultrastructure of sperm and structure of testes. T-2 toxin treatment increased the reactive oxygen species (ROS) and malondialdehyde content, while, decreased the total anti-oxidation capacity (T-AOC) and the superoxide dismutase activity in testes. T-2 toxin exposure increased the TUNEL-positive germ cells, the activities and mRNA expressions of caspase-3, caspase-8 and caspase-9, the mRNA expression of Bax, and inhibited the Bcl-2 mRNA expression. Furthermore, the expressions of caspase-3, caspase-8 caspase-9 and Bax were positively correlated with ROS level, but negatively correlated with T-AOC in testis. In summary, T-2 toxin caused spermatogenesis disorder associated with the germ cell apoptosis medicated by oxidative stress, impairing the male reproductive function.

Novel Pactamycin Analogs Induce p53 Dependent Cell-Cycle Arrest at S-Phase in Human Head and Neck Squamous Cell Carcinoma (HNSCC) Cells. PLoS One 2015; 10:e0125322.

Abstract
Pactamycin, although putatively touted as a potent antitumor agent, has never been used as an anticancer drug due to its high cytotoxicity. In this study, we characterized the effects of two novel biosynthetically engineered analogs of pactamycin, de-6MSA-7-demethyl-7-deoxypactamycin (TM-025) and 7-demethyl-7-deoxypactamycin (TM-026), in head and neck squamous cell carcinoma (HNSCC) cell lines SCC25 and SCC104. Both TM-025 and TM-026 exert growth inhibitory effects on HNSCC cells by inhibiting cell proliferation. Interestingly, unlike their parent compound pactamycin, the analogs do not inhibit synthesis of nascent protein in a cell-based assay. Furthermore, they do not induce apoptosis or autophagy in a dose- or a time-dependent manner, but induce mild senescence in the tested cell lines. Cell cycle analysis demonstrated that both analogs significantly induce cell cycle arrest of the HNSCC cells at S-phase resulting in reduced accumulation of G2/M-phase cells. The pactamycin analogs induce expression of cell cycle regulatory proteins including master regulator p53, its downstream target p21Cip1/WAF1, p27kip21, p19, cyclin E, total and phospho Cdc2 (Tyr15) and Cdc25C. Besides, the analogs mildly reduce cyclin D1 expression without affecting expression of cyclin B, Cdk2 and Cdk4. Specific inhibition of p53 by pifithrin-α reduces the percentage of cells accumulated in S-phase, suggesting contribution of p53 to S-phase increase. Altogether, our results demonstrate that Pactamycin analogs TM-025 and TM-026 induce senescence and inhibit proliferation of HNSCC cells via accumulation in S-phase through possible contribution of p53. The two PCT analogs can be widely used as research tools for cell cycle inhibition studies in proliferating cancer cells with specific mechanisms of action.

Abstract
Sperm DNA fragmentation (sDF) represents a threat to male fertility, human reproduction and the health of the offspring. The causes of sDF are still unclear, even if apoptosis, oxidative assault and defects in chromatin maturation are hypothesized. Using multicolor flow cytometry and sperm sorting, we challenged the three hypothesized mechanisms by simultaneously evaluating sDF and signs of oxidative damage (8-hydroxy, 2'-deoxyguanosine [8-OHdG] and malondialdehyde [MDA]), apoptosis (caspase activity and cleaved poly[ADP-ribose] polymerase [cPARP]) and sperm immaturity (creatine phosphokinase [CK] and excess of residual histones). Active caspases and c-PARP were concomitant with sDF in a high percentage of spermatozoa (82.6% ± 9.1% and 53.5% ± 16.4%, respectively). Excess of residual histones was significantly higher in DNA-fragmented sperm versus sperm without DNA fragmentation (74.8% ± 17.5% and 37.3% ± 16.6%, respectively, p < 0.005), and largely concomitant with active caspases. Conversely, oxidative damage was scarcely concomitant with sDF in the total sperm population, at variance with live sperm, where 8-OHdG and MDA were clearly associated to sDF. In addition, most live cells with active caspase also showed 8-OHdG, suggesting activation of apoptotic pathways in oxidative-injured live cells. This is the first investigation on the origin of sDF directly evaluating the simultaneous presence of the signs of the hypothesized mechanisms with DNA breaks at the single cell level. The results indicate that the main pathway leading to sperm DNA breaks is a process of apoptosis, likely triggered by an impairment of chromatin maturation in the testis and by oxidative stress during the transit in the male genital tract. These findings are highly relevant for clinical studies on the effects of drugs on sDF and oxidative stress in infertile men and for the development of new therapeutic strategies.

Abstract
Poly(ADP-ribose) polymerases (PARPs) are a family of enzymes involved in a wide variety of biological processes, including DNA repair and maintenance of genomic stability following genotoxic stress, and regulates the expression of various proteins at the transcriptional level as well as replication and differentiation. However, excessive activation of PARP has been shown to contribute to the pathogenesis of several diseases associated with oxidative stress (OS), which has been known to play a fundamental role in the etiology of male infertility. Based on the degree and type of the stress stimulus, PARP directs cells to specific fates (such as, DNA repair vs. cell death). A large volume of accumulated evidence indicates the presence of PARP and its homologs in testicular germ line cells and its activity may offer a key mechanism for keeping DNA integrity in spermatogenesis. On the other hand, a possible role of PARP overactivation in OS-induced male reproductive disorders and in human sperm is gaining significance in recent years. In this review, we focus on the findings about the importance of PARP-1 and PARP-2 in male reproduction and possible involvement of PARP overactivation in various clinical conditions associated with male infertility.

Abstract
Our objective was to determine whether oxidative damage of rhesus macaque sperm induced by reactive oxygen species (ROS) in vitro would affect embryo development following intracytoplasmic sperm injection (ICSI) of metaphase II (MII) oocytes. Fresh rhesus macaque spermatozoa were treated with ROS as follows: 1 mM xanthine and 0.1 U/ml xanthine oxidase (XXO) at 37°C and 5% CO₂ in air for 2.25 h. Sperm were then assessed for motility, viability, and lipid peroxidation. Motile ROS-treated and control sperm were used for ICSI of MII oocytes. Embryo culture was evaluated for 3 days for development to the eight-cell stage. Embryos were fixed and stained for signs of cytoplasmic and nuclear abnormalities. Gene expression was analyzed by RNA-Seq in two-cell embryos from control and treated groups. Exposure of sperm to XXO resulted in increased lipid peroxidation and decreased sperm motility. ICSI of MII oocytes with motile sperm induced similar rates of fertilization and cleavage between treatments. Development to four- and eight-cell stage was significantly lower for embryos generated with ROS-treated sperm than for controls. All embryos produced from ROS-treated sperm demonstrated permanent embryonic arrest and varying degrees of degeneration and nuclear fragmentation, changes that are suggestive of prolonged senescence or apoptotic cell death. RNA-Seq analysis of two-cell embryos showed changes in transcript abundance resulting from sperm treatment with ROS. Differentially expressed genes were enriched for processes associated with cytoskeletal organization, cell adhesion, and protein phosphorylation. ROS-induced damage to sperm adversely affects embryo development by contributing to mitotic arrest after ICSI of MII rhesus oocytes. Changes in transcript abundance in embryos destined for mitotic arrest is evident at the two-cell stage of development.
