Objective To elucidate the important functions of microRNAs (miRNAs) in regulating synaptic assembly and function, we performed a computational analysis for the genetic loci required for the synaptic structure and function and their corresponding miRNAs in C. elegans. Methods Total 198 genetic loci required for the synaptic structure and function were selected. Sequence alignment was combined with E value evaluation to investigate and identify the possible corresponding miRNAs. Results Total 163 genes among the 198 genetic loci selected have their possibly corresponding regulatory miRNA (s), which covered most of the important genetic loci required for the synaptic structure and function. Moreover, only 22 genes among the analyzed 38 genetic loci encoding synaptic proteins have more possibility to under the control of non-coding RNA genes. In addition, the distribution of miRNAs along the 3' untranslated region (UTR) of these 22 genes exhibits different patterns. Conclusion Here we provide the computational screen and analysis results for the genetic loci required for synaptic structure and function and their possible corresponding miRNAs. These data will be useful for the further attempt to systematically determine the roles of miRNAs in synaptic assembly and function regulation in worms.
为了阐明 microRNAs(miRNAs)在调节突触组装和功能中的重要作用,我们对秀丽隐杆线虫中突触结构和功能所需的遗传基因座及其相应的 miRNAs 进行了计算分析。
选择了 198 个与突触结构和功能相关的遗传基因座。通过序列比对并结合 E 值评估,对可能的相应 miRNAs 进行了研究和鉴定。
在所选择的 198 个遗传基因座中,有 163 个基因具有可能对应的调节 miRNA(s),这些基因涵盖了大多数与突触结构和功能相关的重要遗传基因座。此外,在分析的 38 个编码突触蛋白的遗传基因座中,只有 22 个基因更有可能受到非编码 RNA 基因的控制。此外,这些 22 个基因的 miRNAs 在其 3'非翻译区(UTR)的分布呈现出不同的模式。
本文提供了与突触结构和功能相关的遗传基因座及其可能对应的 miRNAs 的计算筛选和分析结果。这些数据将有助于进一步尝试系统地确定 miRNAs 在蠕虫突触组装和功能调节中的作用。
