摘要:

PIWI蛋白相互作用RNA(PIWI-interacting RNA,piRNA)是长度大约有24~31个核苷酸的非编码RNA,特异性表达于动物的生殖细胞中。piRNA的生成过程可分为细胞核内的转录以及细胞质内的后期加工两部分。piRNA可以在PIWI家族蛋白的协助下发挥沉默转座子基因和调控mRNA等功能,并可进一步调控生殖功能。在雄性生殖功能中,piRNA可以在PIWI家族蛋白的协助下通过控制组蛋白泛素连接酶RNF8、谷胱甘肽过氧化物酶5等蛋白的表达调控精子发生,引起无精子症、少精子症和弱精子症等影响雄性生殖功能的疾病。在piRNA最初的研究中,学者普遍认为piRNA在雌性生殖方面作用不大,但是近年对金黄地鼠的研究发现piRNA/PIWI复合物在雌性生殖功能的调控过程中也发挥着重要作用。综述piRNA的产生及其与生殖功能的相关性。

Abstract:

PIWI-interacting RNA (piRNA), a kind of non-coding RNAs with a length of about 24-31 nucleotides, is specifically expressed in animal germ cells. The production process of piRNA can be divided into two parts: transcription in the nucleus and post-processing in the cytoplasm. piRNA can silence transcriptional genes, and regulates mRNA with the help of PIWI family proteins, and further regulates reproductive function. In male reproductive function, piRNA can control spermatogenesis by RNF8, glutathione peroxidase 5 and other proteins with the help of PIWI family proteins, resulting in azoospermia, oligozoospermia, asthenospermia and other diseases affecting male reproductive function. In the initial study of piRNA, researcher generally believed that piRNA had little effect on female reproduction. However, recent studies on golden hamsters found that piRNA/PIWI also played an important role in the regulation of female reproductive function. The production of piRNA and its correlation with reproductive function were reviewed.
