Abstract
本发明属于生物医疗领域,具体公开了一种用于治疗卵子成熟障碍的复方制剂,所述复方制剂包含如下浓度的组分:姜黄素(Curcumin,0.5‑200nmol),二氢香豆素(Dihydrocoumarin,0.1‑100nml)、烟酰胺(Nicotinamide,0.1‑100 mmol)、泽布拉林(Zebularine,0.5‑200μmol),佛司可林(Forskolin,0.5‑100μmol)、图巴辛(Tubacin,0.5‑50μmol)、腺苷三磷酸(ATP,1‑20 mmol)、以及二甲双胍(Metformin,0.5‑20mmol)。本发明针对基因突变引起的卵子成熟障碍这一疑难杂症,通过合理配比构成复方治疗型制剂,促进卵母细胞正常减数分裂进程的推进,加快能量代谢,清除代谢活性氧,有利于卵母细胞核成熟,提高受精率和囊胚发育率,表型挽救显著,治疗效果良好。
Description
技术领域
本发明属于生物医疗领域,涉及一种用于治疗因TUBB8、TRIP13、TACC3、PATL2基因突变导致的卵子成熟障碍和女性不孕的制剂。
背景技术
虽然辅助生殖技术(assisted reproductive technology,ART)已广泛应用于多种不孕不育症的治疗,但仍存在一些无法明确和解决的不孕不育病因,如卵母细胞成熟阻滞,目前也被称作一种新的孟德尔遗传病,是一类较为罕见的原发性不孕症。
自1990年报道第一例人类卵母细胞成熟停滞以来,卵子成熟障碍的病因一直处于探索中。自2016年起,TUBB8、TRIP13、TACC3、PATL2等可遗传的人类卵子成熟障碍的致病基因相继被发现,并且可以解释30-40%患者卵子发育停滞的病因,但对于由这些基因突变引起的卵子成熟障碍的治疗目前仍是一片空白。探寻和开发由TUBB8、TRIP13、TACC3、PATL2基因突变引起的卵母细胞停滞相关的治疗方法,对于临床上解决女性生殖障碍相关疾病具有重要的现实意义和指导价值。虽然由TUBB8、TRIP13、TACC3、PATL2基因突变导致的卵母细胞成熟障碍的病因能够通过全外显子测序来确定,但目前尚未发现有对于这类疾病的干预措施能治疗由基因突变导致的卵母细胞成熟障碍,因此迫切需要开发安全且有效治疗卵母细胞成熟障碍的方法。

有益效果
本发明提供的一种用于治疗卵子成熟障碍的复方制剂,与现有技术相比,具有以下有益效果:

(b)通过活性氧检测试剂盒检测携带致病基因点突变的卵母细胞在治疗前后的活性氧ROS水平,结果表明经复方制剂治疗后可明显降低突变卵母细胞ROS水平。
(c)收集相应卵子固定后利用免疫荧光方法于共聚焦显微镜测定细胞内磷酸化、乙酰化水平,发现与对照组相比,注射携带致病点突变cRNA的卵母细胞在含有以上复方制剂的培养基中培养15h后磷酸化水平降低,整体乙酰化水平升高。
(d)收集相应卵子进行体外授精及早期胚胎培养,发现复方制剂的添加提高了注射点突变cRNA卵母细胞的受精能力及早期胚胎发育能力。以上结果都表明该复方制剂能有效治疗卵母细胞突变引起的卵子发育停滞表型,且体外受精实验验证该复方制剂能有效提高基因突变卵母细胞受精率和囊胚发育率,表型挽救显著,治疗效果良好。
