【摘要】:目的研究熱休克蛋白90β(HSP90β)在小鼠睪丸、附睪、精子中的表達(dá)及調(diào)控機(jī)制。方法從mRNA和蛋白水平上對HSP90β在小鼠睪丸和附睪組織細(xì)胞中及精子上表達(dá)及定位進(jìn)行分析,同時對其基因在雄性生殖中的表達(dá)調(diào)控進(jìn)行初步探索。結(jié)果 HSP90βmRNA在小鼠附睪中的表達(dá)量比在睪丸中高。在小鼠精子中定位于頂體部位。其基因在去勢小鼠的附睪中表達(dá)降低,補(bǔ)充睪酮后又恢復(fù)正常,在發(fā)育中小鼠的睪丸、附睪中表達(dá)也有變化。結(jié)論 HSP90β在小鼠精子形成及受精中可能發(fā)揮重要作用;其在去勢小鼠附睪中和在出生后不同階段小鼠睪丸、附睪中的表達(dá)模式,說明其基因表達(dá)受激素調(diào)控和發(fā)育調(diào)控的影響。
[Abstract]:Objective to study the expression and regulatory mechanism of heat shock protein 90 尾 (HSP90 尾) in testis, epididymis and sperm of mice. Methods the expression and localization of HSP90 尾 in mouse testis and epididymis tissues and spermatozoa were analyzed at the level of mRNA and protein, and the regulation of HSP90 尾 gene expression in male reproduction was explored. Results the expression of HSP90 尾 mRNA in mouse epididymis was higher than that in testis. It was located in acrosome in mouse spermatozoa. Its gene expression decreased in the epididymis of ovariectomized mice, then returned to normal after testosterone supplementation, and also changed in the testis and epididymis of developing mice. Conclusion HSP90 尾 may play an important role in mouse spermatogenesis and fertilization, and its expression patterns in the testis and epididymis of ovariectomized mice and postnatal mice at different stages indicate that its gene expression is affected by hormone regulation and developmental regulation.
