文题释义:
成熟的miRNA:是一类内源性非编码单链RNA,其长度为19-25 nt,具有很高的保守型。其通过装载进入AGO2蛋白形成RISC复合物,对靶基因进行转录后调控作用,在生物进程中起到非常重要的作用。每个miRNA可以有多个靶基因,而几个miRNA也可以调节同一个基因。这种复杂的调节网络既可以通过一个miRNA来调控多个基因的表达,也可以通过几个miRNA的组合来精细调控某个基因的表达。人种的为has。miRNA前体:以动物物种缩写-mir-命名顺序,如hsa-mir-227;miRNA成熟链:以动物物种缩写-miR-命名顺序,如has-miR-227-5p。
氟骨症:是指长期摄入过量氟化物引起氟中毒并累及骨组织的一种慢性侵袭性全身性骨病。氟中毒累及牙齿称氟斑牙。1901年,Eaqer最早报道氟斑牙,1932年丹麦的Motlev和Gudijonsson命名为“氟中毒”(fluorosis),并认为本病伴有骨硬化。

摘要
背景:
长期过量摄入氟,尤其是通过饮水,可以引起慢性氟中毒骨病。该病可以导致骨骼损伤和畸形,且难以恢复。目前还没有早期诊断该病的无创或微创方法。
目的:观察人成骨细胞在过量氟作用下凋亡相关miRNA表达的情况。
方法:体外培养人成骨细胞建立染氟模型,用20 mg/L NaF和40 mg/L NaF分别处理24/48 h后用PCR芯片法测定凋亡相关miRNA的表达情况。
结果与结论:①NaF处理24 h后发现成骨细胞内有48条miRNA表达上调,4 条miRNA表达下调;NaF处理48 h有21条miRNA表达上调,2条miRNA表达下调;两个时间点共同上调miRNA有9条,共同下调miRNA有1条;②用生物信息学软件对选出的10条人成骨细胞凋亡相关miRNA进行靶基因分析,涉及抗凋亡和促凋亡的两方面的作用,对于氟骨症的早期鉴别具有一定的理论意义。

Abstract:

BACKGROUND: Long-term excessive intake of fluoride, especially through drinking water, can cause chronic fluorosis of bone. The disease can lead to bone damage and deformity, and is difficult to recover. Unfortunately, we have not developed a noninvasive or minimally invasive method for its early diagnosis.
OBJECTIVE: To observe the expression of apoptosis-related miRNAs under the action of excessive fluorine in human osteoblasts.
METHODS: The fluorine model was established in the human osteoblasts by cultured with 20 and 40 mg/L sodium fluoride for 24 and 48 hours, respectively. The expression levels of apoptosis-related miRNAs were determined by PCR array.
RESULTS AND CONCLUSION: After 24-hour treatment of sodium fluoride, 48 kinds of miRNAs were upregulated and 4 ones were down-regulated in the osteoblasts. After 48-hour treatment of sodium fluoride, 21 kinds of miRNAs were upregulated and 2 ones were down-regulated. It showed that nine up-regulated miRNAs and one down-regulated miRNA were same in two periods. The 10 miRNAs are selected for target gene analysis on bioinformatics software that refer to the effect of anti-apoptosis and pro-apoptosis, which is of great significance for the early identification of skeletal fluorosis.
