目的:探讨雄性大鼠生殖结节中长链非编码RNA(LncRNA)在邻苯二甲酸二丁酯(DBP)诱导雄性大鼠尿道下裂形成中对雄激素调控的影响.方法:在孕鼠孕 13~18 d时按体重 800 mg/kg DBP溶于 1 ml玉米油灌胃,对照组给予玉米油 1 ml/d.于孕 19 d时取出胎鼠,分别取下两组雄性胎鼠的生殖结节,进行全转录组基因测序.对测序结果中LncRNA进行筛选、差异分析和功能预测,再筛选 8 条LncRNA用qRT-PCR验证其表达量.结果:与对照组比较,尿道下裂组生殖结节中有598 个差异mRNA,427 个差异LncRNA,8 条LncRNA差异趋势与测序结果一致,不存在差异趋势与测序结果的差异趋势相反的LncRNA.RT-PCR结果与测序结果一致.共筛选出与雄激素相关的差异表达LncRNAs 130 个,与雄激素生物合成途径相关 11 个,与雄激素受体信号通路的负调控相关 25 个,与雄激素结合相关 10 个,与雄激素受体信号通路激活前列腺诱导相关29 个,与雄激素代谢过程相关 23 个,与雄激素受体结合相关 16 个,与雄激素受体信号通路的正调控相关 3 个.结论:DBP诱导的尿道下裂雄性大鼠与正常雄性大鼠比较,其生殖结节中LncRNA可通过调控雄激素的合成、代谢、结合,雄激素受体的结合,雄激素受体信号通路这几个方面参与尿道下裂的形成.
Long non-coding RNA participates in the regulation of androgen in hypospadiac male rats
Objective To investigate the effect of long non-coding RNA(LncRNA)in the genital tubercle of male rats on androgen regulation in the formation of hypospadias of male rats induced by dibutyl phthalate(DBP).Method The pregnant rats were gived 800mg/kg DBP dissolved in 1ml corn oil in the 13 to 18 days of pregnancy to establish model of hypospadias,the pregnant rats in control group gived only 1 ml/d corn oil.Fetal rats were took out from pregnant rats for 19 days of pregnancy.Removed the genital tu-bercles of male fetal rats and complete whole transcriptome gene sequencing.Analyzed and screened the sequencing result of LncRNA and did function prediction.Finally chose eight LncRNAs to validate their level of expression by qRT-PCR.Results The sequencing results showed that compared with control group,the hypospadias group had 598 differential expression mRNA,427 differential expres-sion LncRNAs.The differential trend of 8 lncRNAs was consistent with the sequencing results,and there was no lncRNA with a differ-ential trend opposite to the sequencing results.The RT-PCR results were consistent with the sequencing results.A total of 130 differen-tially expressed LncRNAs related to androgens were screened,including 11 related to androgen biosynthesis process,25 related to neg-ative regulation of androgen receptor signaling pathway,10 related to androgen binding,29 related to activation of prostate induction by androgen receptor signaling pathway,23 related to androgen metabolism process,16 related to androgen receptor binding,and 3 related to positive regulation of androgen receptor activity.Conclusion Compared with normal male rats,LncRNA in genital tubercle of hypos-padiac male rats induced by dibutyl phthalate participates in the formation of hypospadias by regulating androgen synthesis,metabolism and binding,androgen receptor binding and androgen receptor signaling pathway.
