Nephrotic syndrome represents the clinical situation characterized by presence of massive proteinuria and low serum protein caused by a variety of diseases, including minimal change nephrotic syndrome (MCNS), focal segmental glomerulosclerosis (FSGS) and membranous glomerulonephropathy. Differentiating between diagnoses requires invasive renal biopsies in general. Even with the biopsy, we encounter difficulties to differentiate MCNS and FSGS in some cases. There is no other better option currently available for the diagnosis other than renal biopsy. MicroRNAs (miRNAs) are no-coding RNAs of approximately 20 nucleotides in length, which regulate target genes in the post-transcriptional processes and have essential roles in many diseases. MiRNAs in serum and urine have been shown as non-invasive biomarkers in multiple diseases, including renal diseases. In this article, we summarize the current knowledge of miRNAs as the promising biomarkers for nephrotic syndrome.
肾病综合征代表了一种临床情况,其特征是大量蛋白尿和血清蛋白降低,由多种疾病引起,包括微小病变肾病综合征(MCNS)、局灶节段性肾小球硬化(FSGS)和膜性肾小球肾炎。一般来说,区分这些诊断需要进行有创性的肾活检。即使进行了活检,在某些情况下,我们仍然难以区分 MCNS 和 FSGS。目前,除了肾活检之外,没有其他更好的诊断方法。微 RNA(miRNA)是长度约为 20 个核苷酸的非编码 RNA,在转录后过程中调节靶基因,并在许多疾病中发挥重要作用。血清和尿液中的 miRNA 已被证明是多种疾病(包括肾脏疾病)的非侵入性生物标志物。本文总结了 miRNA 作为肾病综合征有前途的生物标志物的最新知识。
