雄激素受体类似物在雄性拟黑多刺蚁性腺中的表达和定位

目的]探讨雄激素类似物在雄性拟黑多刺蚁性腺中的表达情况。方法]以雄性拟黑多刺蚁为试验材料，采用SABC免疫组织化学方法检测雄性拟黑多刺蚁性腺是否存在雄激素受体类似物，并研究雄激素类似物在其性腺中的表达情况。结果]免疫组织化学研究结果显示，在雄蚁的性腺内有雄性激素受体类似物的免疫阳性颗粒表达，主要分布在雄性附腺与精巢里。表明拟黑多刺蚁体内存在内源性类固醇雄激素类似物，其信号通路在调解其精卵发生方面有重要的作用，并且有与脊椎动物类似的性激素调控性征的通路。结论]该研究为雄激素类似物功能的研究奠定了基础。

Expression and Location of Androgen Receptor Analogue in Sex Gland of Male Polyrhachis vicina Roger

Objective] The aim was to discuss the expression condition of androgen analogue in sex gland of male Polyrhachis vicina.Method] With male P.vicina as experimental material,whether there existed androgen receptor analogue in sex gland of male P.vicina or not was detected by SABC immunohistochemistry and the expression condition of androgen analogue in sex gland of male P.vicina was studied.Result] The result of immunohistochemistry showed that the immunoreactive grain of androgen receptor analogue were expressed in sex gland of male P.vicina and mainly distributed in male accessory gland and testis,which showed that there existed endogenous steroid androgen analogue in P.vicina body,and its signal pathway played an important role in mediating the occurrence of its sperm egg and it had pathway similar to sex hormone regulation characteristic of vertebrate.Conclusion]The research laid the foundation for study on the function of androgen analogue.
