Transgenic overexpression of miR-466a significantly disturbs OREBP/NFAT5 renal expression and induces phenotypes that resemble diabetes insipidus in human

Abstract

目的miR-466(a/b/c/e)-5p/3pmiRNAs是两组高度保守的miRNAs,其中-5p组间和-3p组间miRNAs的序列几乎完全一样。生物信息学分析和我们的前期研究显示,miR-466miRNAs可能可以在肾组织中对渗透应激调控转录因子OREBP/NFAT5进行转录后表达调控。我们因此希望研究miR-466a在转基因小鼠中的过表达对小鼠肾组织OREBP/NFAT5的表达和小鼠尿液浓缩机制的影响。 方法通过PCR从小鼠基因组中扩增miR-466a基因序列,将片段插入鸡-actinpromoter下游构建过表达质粒pBact-miR-466a,然后用限制性内切酶酶切...Background miR466(a/b/c/e)-5p/3p miRNAs are two groups of highly conserved miRNAs, with virtually identical sequences in either the -5p group or the -3p group. Bioinformatic analyses and our previous studies indicate that these groups of miRNAs might participate in the post-transcriptional regulation of osmoregulatory transcription factor OREBP/NFAT5 in the kidney. In this study, we created transg...学位:理学硕士院系专业:生命科学学院_生物化学与分子生物学学号:2172009115206
