摘要:

文题释义:
核心子网:将所有牙周重建相关的生物学过程内的所有基因映射到调控网络内,如果一对牙周重建相关的基因在网络内直接相连,文章保留这对基因,从而得到一个直接相连的牙周重建相关的核心子网。由于子网通常具有复杂的网络结构,因此,对得到的核心子网进行深入分析,用广度优先算法将这一子网内的所有线性通路挖掘出来,每条通路内都包含转录因子和靶基因。
生物信息学:是生命科学和计算机科学相结合形成的一门新科学,通过综合应用生物信息学技术,可以帮助分析和处理大量的实验数据,加快实验进程并缩短科研时间,指导设计后续的实验目标。近年来,生物信息学技术逐步在医学领域应用发展起来,也为口腔专业的科研工作带来了崭新的思路和方法。
背景:在牙周重建组织工程学中,包含基因众多且无法通过生物实验逐一验证。借助生物信息学手段,整合分析相关基因,构建牙周重建相关的级联调控通路,从而找到开启牙周重建的关键基因。
目的:文章以分析牙周重建生物过程和调节机制为着眼点,旨在筛选出牙周重建过程中关键性的启动基因,为牙周重建治疗寻找理想的基因靶点。
方法:①采用GO功能注释体系,对参与牙周重建的干细胞分化、骨组织改建以及牙周软组织形成功能的基因做整合分析,找出各功能交集基因;②集成TRANSFAC、TarBase、TransmiR、miRTarBase及miRecords数据库,建立“牙周重建相关的级联调控通路”,将牙周重建生物学过程内的所有基因映射到调控网络内,用广度优先算法将这一子网内的所有线性通路挖掘出来,找出调控上游基因。
结果与结论:①干细胞分化、成骨细胞分化/成骨细胞增殖以及成纤维细胞增殖3种生物功能的交集基因是CDK6和SFRP1;②级联调控通路中,可以作为上游调控牙周重建的关键基因有3个一级基因:骨形态发生蛋白7、PAX2和SMAD3,有2个二级基因:RUNX2和JUN,有2个3级基因:ESR1和GNAS;上游起始基因多包含在成骨细胞分化/成骨细胞增殖功能过程中;③结果证实:SFRP1,骨形态发生蛋白7,PAX2,SMAD3,RUNX2,JUN,ESR1,GNAS基因在牙周重建过程中起关键作用。牙周重建过程极有可能开始于骨组织改建,包括成骨细胞分化和成骨细胞增殖,接下来是成纤维细胞增殖。

Abstract: BACKGROUND: In periodontal reconstruction tissue engineering, there is a wide range of options for biological signals which cannot be verified in sequence. Using bioinformatics methods, the relevant genes are integrated and analyzed, and the cascade regulatory pathways related to periodontal reconstruction are constructed, to find the key to open periodontal reconstruction.
OBJECTIVE: To focus on periodontal reconstruction process and regulatory mechanism, aiming at screening out the key initiating genes in periodontal reconstruction and identify ideal gene targets for periodontal therapy.
METHODS: GO function annotation system was used to analyze the genes of three biological functions including differentiation, osteogenesis, and fibrogenesis involved in periodontal reconstruction, and identify the intersection genes of each function. Integrated data from the major information databases of TRANSFAC, TarBase, TransmiR, miRTarBase and miRecords were collected to establish a "cascade regulatory pathway related to periodontal reconstruction," mapping all the genes in the biological process of periodontal reconstruction onto the regulatory network, to find out all the linear pathways in this subnet by breadth-first algorithm, and to seek the upstream regulatory genes. 
RESULTS AND CONCLUSION: The intersection genes of the three biological functions of stem cell differentiation, osteoblast differentiation/osteoblast proliferation, and fibroblast proliferation are CDK6 and SFRP1. In the cascade regulatory pathway, there are three primary genes that can be used as the key genes for upstream regulation of periodontal reconstruction: bone morphogenetic protein 7, PAX2 and SMAD3, two secondary genes: RUNX2 and JUN, and two tertiary genes: ESR1 and GNAS. The upstream initiation genes are mostly involved in the process of osteoblast differentiation/ osteoblast proliferation. It is predicted that there are eight possible genes that play a key role in the periodontal reconstruction process: SFRP1, bone morphogenetic protein 7, PAX2, SMAD3, RUNX2, JUN, ESR1, GNAS. The periodontal reconstruction process is highly possible to start with cell osteogenesis, including osteoblast differentiation and osteoblast proliferation, followed by fibroblast proliferation.
