Total RNA was isolated using the RNeasy Mini Kit (Qiagen Inc., Redwood City, CA) with on-column DNase digestion using the RNase-Free DNase Set (Qiagen Inc., Redwood City, CA). Following reverse transcription into cDNA with the Transcriptor First Strand cDNA Synthesis Kit (Roche Applied Sciences, Indianapolis, IN), samples were analyzed by real time PCR on a 7500 Real Time PCR System instrument (Applied Biosystems, Inc., Foster City, CA) using EagleTaq Universal Master Mix (Roche Applied Sciences, Indianapolis, IN). Target gene expression was normalized to 18S rRNA expression. The primers and probes used in this study are displayed in S7 Table, or have previously been described [24 (link),62 (link)–65 (link)]. Note that, although there was insufficient mRNA from biopsy samples to perform extensive qRT-PCR validation of gene expression, in contrast to microarray, RNA-Seq has high concordance with qRT-PCR data [28 (link)].

RNA was extracted from TECs after digestion and CD45 cell-depletion using the RNeasy Micro kit (QIAGEN, Hilden, Germany). Reverse transcription of mRNA was performed with the High Capacity Reverse Trancription Kit (Applied Biosystems, Foster City, CA, USA). Real-time PCR was performed using TaqMan Gene expression Assays (Applied Biosystems) and the EagleTaq Universal Master Mix (Roche, Basel, Switzerland). PCR reactions were performed in MicroAmp®Optical 96-well reaction plates (Applied Biosystems) in a final volume of 25 μl and run on the Viia-7 Real-Time PCR machine (Applied Biosystems). Relative quantification of genes was performed with the 2−ΔΔCt method and expressed as fold change relative to the expression of the endogenous control, RPLPO.

Total RNA was isolated from kidney tissues using an RNeasy Mini Kit (Qiagen). RT of 1 μg of total RNA was performed using Takara PrimeScript RT Master Mix (Takara Bio Inc.). mRNA expression was measured by real-time PCR using a TaqMan gene expression assays (Thermo Fisher Scientific). Primers for mouse Rhcg mRNA (Mm00451199_m1), rat Rhcg (Rn00788284_m1), and mouse and rat GAPDH (Mm99999915_g1) were from Thermo Fisher Scientific. Primers for rat Sgk1 (NM_019232) were designed (sense: CAACCTGGGTCCATCCTCAAA; anti-sense: GTTTTGGAAAGGTTCTTCTAGCAAG; probe: CCCACGCCAAACCCTCTGACTTCCAC) and purchased from Sigma-Aldrich Japan. Real-time PCR was performed in a LightCycler 480 system (Roche Life Science). EagleTaq Universal Master Mix (Roche Life Science) was used for amplification. Ct values from Rhcg or Sgk1 were normalized by the subtraction of the Ct values of Gapdh. The ΔCt was calculated by the subtraction of Ct for mice or cells with vehicle from that for mice or cells treated, and was then applied to the 2-ΔCt equation. Fold difference was determined relative to vehicle.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
