Description
技术领域
本发明属于分子生物学领域,涉及一种环状非编码RNA-circSP3在治疗早期动脉粥样硬化中的影响及其应用。
背景技术
动脉粥样硬化(atherosclerosis,AS)是一种由多种因素多种细胞参与的慢性复杂性疾病。其是以血管内皮损伤为始点,伴随着炎症、免疫反应,血管壁中的脂质沉积,涉及到主要功能细胞,包括平滑肌细胞、内皮细胞和免疫细胞的炎性和增殖性级联反应。现有的研究方法和手段已经对AS的发生发展有了一定的认知与了解,对心血管疾病的诊断和治疗有了实质性的改善,但早期动脉粥样硬化发生发展由于未完全暴露其临床特征,早期有效的临床干预容易被忽视。尽管等人发现他汀、白介素-1可以通过降脂、抗炎等来抑制早期斑块发展,但其带来的残存风险依旧很高,因此探求早期动脉粥样硬化病变形成的机制仍然是重要的。
平滑肌细胞(smooth muscle cells,SMC)在AS斑块形成、进展中发挥着重要的功能,研究表明,在AS斑块内含有的各种细胞中,70%左右来源于SMC。 AS早期,SMC通过异常增殖迁移并合成细胞外基质是损伤的关键;此外,SMC 分泌多种促炎、促增殖因子并募集巨噬细胞;SMC还通过吞噬摄取脂质,形成泡沫细胞。因此VSMC与早期AS的发生发展密不可分。
环状RNA(circular RNA,circRNA),是一类新兴的非编码RNA,在真核生物中普遍存在,表达稳定且在物种间高度保守。研究表明,circRNA在动脉粥样硬化、冠脉斑块形成、斑块破裂等病理生理过程中出现不同水平的变化,AS 作为一种基因遗传易感性疾病,转录水平的研究可以更深入的阐述其发生发展,有助于我们更好的理解其发病机制,进而从RNA水平为AS提供新的诊疗靶点。
发明内容
本发明的目的之一在于提供一种在早期动脉粥样硬化动脉组织相较于正常动脉组织中高表达且在物种间高度保守的环状非编码RNA-circSP3及其应用,上述circRNA可作为干预动脉粥样硬化的新靶点。
本发明的目的之二在于提供上述环状非编码RNA-circSP3的抑制剂及其在制备治疗早期动脉粥样硬化药物中的应用。

更进一步,本发明还提出了所述的环状非编码RNA作为分子标记和靶点在制备治疗早期动脉粥样硬化药物中的应用。
更进一步,本发明还提出了所述的环状非编码RNA的抑制剂在制备治疗早期动脉粥样硬化药物中的应用。
相较于现有技术,本发明的有益效果是:
本发明通过对小鼠AS模型中的动脉组织进行全转录组高通量测序,筛选到在早期AS组相较于正常组高表达,且保守性高的circSP3。为进一步研究circSP3 对SMC功能的影响,构建siRNA沉默人类主动脉平滑肌细胞(HASMC)的circSP3,研究circSP3对SMC的增殖、迁移等功能中的作用。结果证实,体外转染siRNA 沉默circSP3可显著抑制SMC的增殖和迁移,通过AAV病毒干扰早期AS模型 APOE-/-血管circSP3表达,可以抑制早期斑块形成与进展,表明circSP3在早期动脉粥样硬化阶段发挥着重要的作用,可作为诊疗早期动脉粥样硬化新的分子标记和干预靶点。同时,本发明也为早期动脉粥样硬化的预防和治疗提供了新的技术手段。

8周龄雄性ApoE-/-小鼠被随机分为三组并给予高脂饮食,分别为:生理盐水组(Saline组)、腺相关病毒空载体(AAV-NC)组以及circSP3沉默组(AAV- sh-circSP3),通过尾静脉注射到小鼠体内。在小鼠高脂开始时同时尾静脉注射,每次注射200ul体量,滴度为1012。小鼠高脂6周后给予麻醉,在体式显微镜下,分别取材小鼠心脏及小鼠主动脉。
2.2小鼠主动脉根部病理HE染色
切片后固定,固定时间为30s-1min,清水稍冲洗1-2s;玻片浸没于含苏木素的染缸中,时间大概为3-5min;然后清水洗去苏木素,大概5-10s;返蓝5-10s,清水稍冲洗1-2s,显微镜下观察,细胞核蓝色;再把玻片浸没于含伊红的染色缸中 30-60s,然后清水冲洗干净表面;利用不同浓度的酒精(从低浓度—高浓度)和二甲苯进行该项操作。显微镜下观察,细胞核蓝色,胞质、肌纤维、胶原纤维和红细胞呈现出深浅不一的红色。
2.3小鼠主动脉根部病理油红O染色
选择10um冰冻切片,室温平衡5分钟,蒸馏水反复冲洗5次;擦干片子,滴加60%异丙醇30-40秒,弃除液体;滴加油红O置于孵膜中35分钟,观察,着色明显后置于水中;滴加苏木染色3分钟,流水终止染色,镜下观察,并反蓝。
2.4小鼠主动脉根部病理Masson染色
冷丙酮固定切片,PBS冲洗,苏木素染细胞核;masson染色试剂盒内丽春红酸性品红液染5-10min,蒸馏水快速漂洗;磷钼酸水溶液处理约3-5min;苯胺蓝液复染5min;脱水透明。
3.结果
AAV干预早期AS模型鼠主动脉中circSP3的表达效果如图5所示。体内敲减circSP3与对照组相比可显著抑制早期小鼠动脉粥样硬化斑块的进展(图6)。
