The invention belongs to the technical field of bone diseases, in particular to a method for promoting bone application of key microRNAs in bone diseases, which includes the following contents: S1, abnormally expressed micronucleotides in fracture nonunion diseases, the microRNAs are HSA microRNA 196a; the expressions of S2 and microRNA change in disease state, and the changes are obvious in plasma HSA microRNA 196a of patients with fracture nonunion. Low expression; Feasibility analysis of disease diagnosis by S3 and microRNA. The analysis indicated that HSA microRNA 196a was characteristic microRNA of fracture nonunion disease with good specificity and sensitivity; Regulation of osteogenic differentiation by S4 and microRNA; S5 and microRNA interfered with downstream gene expression. Based on a total of 130 clinical normal people and blood samples of patients with fracture nonunion, the present invention detects and compares microRNA with previous research results and relevant literature, and concludes that the plasma expression of HSA microRNA 196a in patients with fracture nonunion is significantly lower than that in normal people, only 1/200.
【技术实现步骤摘要】
一种骨疾病关键microRNA的促成骨应用方法
本专利技术属于骨疾病
,具体涉及一种骨疾病关键microRNA的促成骨应用方法。
技术介绍
微小核苷酸microRNA为一类18-25bp的非编码RNA,在细胞核内经转录后由Drosha酶催化生成前体microRNA,随后胞浆Dicer酶剪切为成熟的microRNA。microRNA因具有易修饰、易与材料构成复合物及靶向运输的特点,从而成为极具潜力的新型小分子药物。miRNA对骨再生的调控主要体现在以下几个方面:促进骨髓间充质干细胞成骨分化,促使成骨前体细胞成熟及增强成骨细胞功能。深入研究miRNA调控骨再生的分子机制,将为今后小分子治疗策略的研发提供理论依据。现有的技术存在以下问题:1.“金标准”自体骨移植,其治愈率约为62%-80%,但供骨区并发症率高、仅用于面积小的骨折不连接修复。2.异体骨移植,存在细胞活性低、促进骨再生能力弱及诱导移植物抗宿主疾病的风险。3.生物材料,该疗法仍处于起步阶段,其确切疗效有待进一步验证。
