- HBV DNA integration might cause c-fos activation and/or p53 mutation, and then lead to the occurrence of liver cacinama. HBVDNA的整合可能引起c-fos的激活和/或p53的突变,从而导致肝癌的发生。
- Objective: To explore the effects of cryopreservation on sperm DNA integrity of infertile men. 摘要目的探讨冷冻保存对不育患者精子核DNA链完整性的影响。
- The DNA integrity of sperm is essential for fertilization,as well as for the normal development of the blastocyst,embryo and child. 精子DNA完整性异常,会影响受精和胚胎发育,最终导致不孕不育、流产、死产、子代智力低下和染色体疾病。
- Method: Sperm DNA integrity of 40 semen samples from nonoligospermatism infertile men were detected by the using of comet assay before freezing and after thawing. 方法采用彗星试验检测40例非少精子症不育患者精液冷冻前及复苏后精子核DNA链的完整性。
- HBV need a viral-coded reverse transcriptase to replicate because the virion DNA is synthesized from an RNA template, and have their DNA integrated into cellular DNA during replication. 需要病毒编码的逆转录酶来增殖,因为病毒体DNA是从RNA模板合成的并在复制时将DNA整合到细胞DNA。
- Conclusion: Cryopreservation does not affect DNA integrity of undamaged sperm of infertile men, however, it can increase the degree of DNA damage of sperm that had been damaged before freezing. 结论精液冷冻对不育患者完整的精子核DNA链无影响,但可能加重冷冻前已有损伤精子核DNA链的损伤程度。
