We were able to measure the expression levels of miRNAs in the kidneys of an IgA nephropathy mouse model (HIGA mice) using this new method. IgA nephropathy is an unexplained disease that needs further research to clarify its etiology and therapeutic targets1,3. However, obtaining human kidney samples is highly invasive. This new technique is advantageous in that it allows the study of IgA nephropathy using small animals and should facilitate future research into ...

Immunoglobulin A (IgA) nephropathy is a type of primary glomerulonephritis characterized by the abnormal deposition of IgA in the renal glomerular mesangial region1,2. It is the most common of the primary glomerulonephritis and leads to the end-stage renal failure in 20%&#8211;40% of patients2. The cause is still unknown but persistent mucosal infection has been implicated1,3. Corticosteroids, immunosuppressants, and renin&#8722;angiotensin system inhibitors have been proposed as therapeutic methods1,3, but have not been completely established3. Therefore, further research is required to clarify the etiology and therapeutic methods of treating IgA nephropathy.
microRNAs (miRNAs) are small, non-coding RNAs that play an important role in regulating gene expression4,5. miRNAs are reported to be involved in the pathogenesis of various diseases, and some have been identified as disease biomarkers and therapeutic agents4,5. In recent years, an association between miRNAs and the pathogenesis of IgA nephropathy has also been reported2,6,7. For example, miR-148b was shown to be involved in structural abnormalities of IgA in patients with IgA nephropathy2,6,7, while miR-148b and let-7b were documented as novel biomarkers for detecting IgA nephropathy7. Although understanding the effects of miRNAs on IgA nephropathy may help further elucidate etiology and treatment2, standard methods for profiling miRNAs in IgA nephropathy using small animal models have not yet been established2.
We herein developed a simple and reliable method for measuring miRNA expression levels in the kidneys of an IgA nephropathy mouse model (HIGA mice). The HIGA mouse is a characteristic ddY strain showing a particularly high level of serum IgA and the abnormal deposition of IgA in kidney glomeruli8,9,10,11. Therefore, HIGA mice can be used as an IgA nephropathy mouse model8,9,10,11. Our method consists of four major steps: first, surgically obtaining kidney samples from HIGA mice; second, homogenizing samples and purifying total RNA using a silica membrane-based spin column; third, synthesizing complementary DNA (cDNA) from total RNA using reverse transcription; and fourth, detecting the expression levels of miRNA by quantitative reverse-transcription polymerase chain reaction (qRT-PCR). The rationale for this method and the reliability of the results are based on previous reports12,13. We show that this is a useful technique to accurately measure miRNA expression levels in an IgA nephropathy mouse model, and that it could be used to facilitate future research into miRNAs in IgA nephropathy.

detection of microrna expression in the kidneys of immunoglobulin a nephropathic mice

Immunoglobulin A (IgA) nephropathy is a type of primary glomerulonephritis characterized by the abnormal deposition of IgA, leading to the end-stage renal failure. In recent years, the involvement of microRNAs (miRNAs) has been reported in the pathogenesis of IgA nephropathy. However, there is no established method for profiling miRNAs in IgA nephropathy using small animal models. Therefore, we developed a reliable method for analyzing miRNA in the kidney of an IgA mouse model (HIGA mouse). The goal of this protocol is to detect the altered expression levels of miRNAs in the kidneys of HIGA mice when compared with the levels in kidneys of control mice. In brief, this method consists of four steps: 1) obtaining kidney samples from HIGA mice; 2) purifying total RNA from kidney samples; 3) synthesizing complementary DNA from total RNA; and 4) quantitative reverse transcription polymerase chain reaction (qRT-PCR) of miRNAs. Using this method, we successfully detected the expression levels of several miRNAs (miR-155-5p, miR-146a-5p, and miR-21-5p) in the kidneys of HIGA mice. This new method can be applied to other studies profiling miRNAs in IgA nephropathy.

We investigated the expression levels of miRNAs in the kidneys of HIGA mice (n=10). This result was obtained completely based on the described protocol. The kidneys of Balb/c mice were selected as the control (n=10). In both groups, aged 25 weeks were selected. Only female HIGA mice were available from the supplier. The expression levels of three miRNAs (miR-155-5p, miR-146a-5p, and miR-21-5p; Figure 1) were detected, which were previously reported to be associated with IgA nephropathy<sup c...
