The expression profiling of 798 miRNAs was carried out by the nCounter human v3 miRNA expression assay (NanoString Technologies, Seattle, WA, USA), as previously described [24 (link)].
The expression levels of DICER1, DROSHA, TARBP2, DGCR8 and XPO5 were evaluated by RT-PCR using the QuantiTect Primer Assay (Qiagen Inc, Hilden, Germany), and following the manufacturer’s instructions. In detail, the retrotranscription step was performed using the RevertAid First Strand cDNA Synthesis Kit (Thermo Scientific, Waltham, MA), as previously reported [22 (link)]. Fifty ng of cDNA were then used in a reaction volume of 25 μL with the Rotor-Gene SYBR Green PCR Master Mix (Qiagen Inc, Hilden, Germany), and with specific primers. Amplification was performed in 40 cycles (denaturation at 95°C for 5 sec, annealing and elongation at 60°C for 10 sec). Actin beta (ACTB) and glyceraldehyde-3-phosphate dehydrogenase (GAPDH) were used as housekeeping genes, and thyroglobulin (TG) was used as specificity control. Each sample was amplified in double copy. The ΔΔCt method was used to assess the relative quantification of the targets [25 ].

To validate the NGS data, the expression of microRNAs was analyzed via quantitative real-time reverse transcription polymerase chain reaction (qRT-PCR) with the Rotor-Gene SYBR Green PCR Kit, miScript Primer Assays, and miScript Universal Primer, following reverse transcription of total RNA with the miScript II RT Kit (Qiagen; Hilden, Germany).
The qRT-PCR analysis was performed in technical replicates according to the manufacturer's instructions using the Rotor-Gene SYBR Green PCR Master Mix (Qiagen; Hilden, Germany). The packaged operating software was utilized for instrument control, data acquisition, and raw data analysis. The plates were run in relative quantification (ΔΔCt) mode with triplicate measurements.
Amplification curves were analyzed using the packaged operating software, and assays were inspected for distinct melting curves. In addition, only assays detected with Ct < 35 were included in the data analysis. To calculate the relative expression levels of target microRNAs, the ΔΔCt algorithm method was utilized. miR-423-3p and miR-423-5p were stably expressed across all samples, thus the average of their Cts in each sample was used as the normalization factor. Assays were calibrated to the same normal skin sample.

Total rice RNA was isolated using the Easy-spin total RNA extraction kit (iNtRON Biotechnology) according to the manufacturer’s instructions. First-strand cDNAs were synthesized using 2 μg of total RNA and the ImProm-II Reverse Transcription System (Promega) with oligo (dT) primers. qRT-PCR reactions were performed using a Rotor-Gene Q real-time PCR cycler (Qiagen) and the gene-specific primers listed in Supplementary Table 11. Each PCR tube contained 5 μl of 2× Rotor-Gene SYBR Green PCR master mix (Qiagen), 25 ng of cDNA, and 15 pmol of each primer. The thermal cycling conditions were 10 min at 94 °C followed by 40 cycles of 15 s at 94 °C and 1 min at 60 °C.
The quality of extracted RNA samples was assessed using Bioanalyzer 2100 (Agilent). RNA-Seq libraries were prepared using the TruSeq RNA Library Prep Kit (Illumina) and sequenced using HiSeq2500 (Illumina). Raw sequence reads were trimmed to remove adaptor sequences, and those with a quality lower than 20 were removed using the NGS QC Toolkit v2.3.349 (link). All reads were assembled and mapped via the use of HISAT2 v2.1.050 (link) and StringTie v1.3.551 (link). DEGs in the MoHTR-OX lines were identified as the genes whose transcript abundance was ≥ 2-fold higher or ≤ 0.5-fold lower than their transcripts in Nakdong rice.

Quantitative Analysis of IGF2 CNV

Check if the same lab product or an alternative is used in the 5 most similar protocols
The CNV of IGF2 gene was analyzed using the qBiomarker CNV PCR Assay for Human chromosome 11 tile 10,752 (Qiagen). This assay is based on amplification and quantification of an IGF2 sequence in relation to two reference genes ZNF80 and GPR15 [40 (link)]. Quantitative PCR reactions were performed according to manufacturer’s protocol in triplicates in 20 μl reaction volume containing Rotor-Gene Sybr Green PCR Master Mix (Qiagen). Data generated by qPCR were analyzed using the commercially available qBaseplus software (Biogazelle NV, Zwijnaarde, Belgium). The reference genes ZNF80 and GPR15 were used for normalization of the relative CNV values. Three blood DNA samples from healthy donors, assumed to have normal diploid genomes, were used as additional calibrators for calculation of CNV in different PCR runs. A minimum 2-fold increase of IGF2 copy numbers in comparison to blood DNA samples was determined as a “gain”, and a decrease of IGF2 copy numbers (less than 0.5-fold) was determined as a “loss”. Values similar to those in blood DNA samples were considered as “normal”.
