摘要:

本试验通过对性成熟公鸡睾丸组织中神经生长因子(nerve growth factor, NGF)及其受体酪氨酸激酶(tyrosine kinase, TrkA)的表达定位,研究促卵泡素(FSH)对睾丸中NGF及TrkA mRNA表达的影响。选用28只20周龄的庄河大骨鸡公鸡,随机分为4组,分别是对照组和3个FSH处理组。处理组连续静脉注射FSH5天,第6天采集睾丸组织。结果显示:公鸡睾丸组织中存在NGF和TrkA的mRNA及蛋白,且二者主要表达于精原细胞、精母细胞和精子细胞;FSH处理组的TrkA mRNA水平显著高于对照组(P<0.05),且TrkA mRNA的表达水平随着FSH浓度的增加而增加,但NGF mRNA的表达水平无显著性差异(P>0.05)。总之,以上研究结果表明公鸡睾丸组织中存在NGF和TrkA,且FSH可能通过调节TrkA的表达影响NGF在精子生成过程中的作用。

Abstract:

In this experiment, we studied the expression of nerve growth factor (NGF) and its receptor tyrosine kinase (TrkA) in the testis of sexually mature roosters, and the influence of FSH in the testis on TrkA mRNA expression. Twenty-eight Zhuanghe Big Bone Chicken roosters aged twenty weeks were selected and randomly divided into 4 groups, namely the control group and three FSH treatment groups. In the treatment group, FSH was intravenously injected for five days, and testicular tissue was collected on the sixth day. The results showed that there were NGF and TrkA mRNA and protein in rooster testis tissue, and both of them were mainly expressed in spermatogonia, spermatocytes and sperm cells; TrkA mRNA levels in the FSH treatment group were significantly higher than those in the control group (P<0.05), and the expression level of TrkA mRNA increased with the increase of FSH concentration, but there was no significant difference in the expression level of NGF mRNA (P>0.05). In summary, the above results indicate that there are NGF and TrkA in rooster testis tissue, and FSH may affect the role of NGF in sperm production by regulating the expression of TrkA.
