文题释义:
差异表达基因:在细胞分化过程中某些奢侈基因表达的结果生成一种类型的分化细胞,另一组奢侈基因表达的结果导致出现另一类型的分化细胞的现象。miRNAs:是在真核生物中发现的一类内源性的具有调控功能的非编码RNA,由20-25个核苷酸组成。成熟的miRNAs是由较长的初级转录物经过一系列核酸酶的剪切加工而产生的,随后组装进RNA诱导的沉默复合体,通过碱基互补配对的方式识别靶mRNA,并根据互补程度的不同指导沉默复合体降解靶mRNA或者阻遏靶mRNA的翻译。
 
背景:目前强直性脊柱炎的发病机制尚不清楚,其发生可能与遗传因素、环境因素、慢性感染和自身免疫功能紊乱等因素有关。目前普遍认为遗传学因素在发病机制中起着重要作用,而且强直性脊柱炎的发病具有明显的家族聚集以及民族间的差异现象,目前寻找不同地区、不同民族之间强直性脊柱炎的差异性基因成为研究热点之一。
目的:应用基因表达谱芯片技术筛选出当地维吾尔族与汉族强直性脊柱炎患者差异性基因,并对这些差异性基因进行比较分析。
方法:随机采集新疆维吾尔自治区中医医院风湿科处于活动期的维吾尔族、汉族强直性脊柱炎患者各5例,另外分别选取各3例健康志愿者为对照,提取外周血中的RNA,制备探针后用于表达谱芯片杂交,筛选强直性脊柱炎组织差异表达基因,并采用半定量 RT-PCR法验证芯片结果。
结果与结论:通过对维吾尔族强直性脊柱炎与汉族强直性脊柱炎患者差异性基因表达研究发现,两组之间筛选出差异有显著性意义的miRNA 20个(P < 0.05);通过对维吾尔族强直性脊柱炎与汉族强直性脊柱炎患者靶基因与miRNA对应关系分析发现,相关的靶基因共有15个,这些靶基因相对应并存在一定的调控关系的miRNA有79个,这些基因主要为白细胞抗原类和白细胞介素类,均与人体免疫相关。结果证实,在中国新疆地区维吾尔族与汉族强直性脊柱炎患者之间,可筛选出与强直性脊柱炎相关多个差异表达基因。

Abstract:

BACKGROUND: Genetic factors, environment, chronic infection, and autoimmune disorders are considered to be involved in the pathogenesis of ankylosing spondylitis. Genetic factors play an important role in the pathogenesis of the disease. Ethnic and regional diversity of differentially expressed genes has become research hotspot because of family aggregation and ethnic diversity of ankylosing spondylitis.

OBJECTIVE: To screen differentially expressed genes in Xinjiang Uygur and Han patients with ankylosing spondylitis by microarray screening and compare differences in gene expressions.
METHODS: Uygur and Han patients with active ankylosing spondylitis in department of rheumatology of our hospital were randomly collected with five patients for each. In addition, three healthy volunteers were selected as controls. RNA from peripheral blood was extracted and used for microarray hybridization after probe preparation to screen differentially expressed genes in ankylosing spondylitis samples and the microarray results were verified by semi-quantitative RT-PCR analysis.
RESULTS AND CONCLUSION: Twenty differentially expressed miRNAs were screened in Uygur and Han patients with active ankylosing spondylitis (P < 0.05). From relationship analysis of target genes and miRNAs, 15 target genes corresponding to the 79 miRNAs involved in human leucocyte antigens and interleukins which linked to human immunity system were found. These findings suggest that differentially expressed genes can be screened from Uygur and Han patients with ankylosing spondylitis.
