For fine-scale mapping of resistance, we generated a second F2 segregation generation. As described above, we started with a mass cross between a single female from DH-R and a single male from the DH-S strain. The F2 segregating population was obtained by crossing F1 population. The progeny of F2 population were put on diet treated with 0.5 μg Vip3Aa per cm2 diet. Ninety-six survivors were selected and named F2-R. Genomic DNA was extracted individually using a Multisource Genomic DNA Miniprep Kit (Axygen, New York, USA) according to the manufacturer’s recommendations.
Based on the SNPs calculated from the genomic resequencing data and the reference genome data, we designed primers specific for the exons of functional genes spanning 10.01 to 10.63 Mb on chromosome 27. PCR amplification and sequencing were performed for parent moths. SNPs that were homozygous in DH-S and different homozygous SNPs in DH-R were selected as informative markers. To evaluate genetic linkage with resistance for each marker, we used the chi-square test to check for significant deviation between the observed and expected genotype frequencies (rr:rs:ss = 1:2:1).

Genomic DNA was isolated from the peripheral whole blood of 18 HCM patients and 100 healthy controls using a genomic DNA Miniprep kit (AxyPrep; Axygen, Union City, CA, USA) following the manufacturer's protocol. OD260/280 of DNA samples was ~1.8 after purification with AMPure XP reagents (Beckman Coulter, Fullerton, CA, USA). The DNA concentration was measured using the Qubit dsDNA HS assay kit (Life Technologies, Carlsbad, CA, USA). Whole coding exons and in exon-intron boundaries of 19 HCM-related genes were amplified and then sequenced on Ion Torrent PGM (Life Technologies). These genes were MYH7, myosin binding protein C (MYBPC3), α-actinin 2 (ACTN2), desmin (DES), α-galactosidase A (GLA), lysosome-associated membrane protein 2 (LAMP2), LIM domain-binding 3 (LDB3), α-myosin heavy chain (MYH6), regulatory myosine light chain 2 (MYL2), regulatory myosine light chain 3 (MYL3), TAZ, myopalladin (MYPN), AMP-activated protein kinase (PRKAG2), sodium channel, voltage-gated type V α-subunit (SCN5A), Titin-cap (TCAP), troponin I 3 (TNNI3), troponin T 2 (TNNT2), α-tropomyosin 1 (TPM1), and vinculin (VCL).

Quantifying Cytosolic Mitochondrial DNA

Mitochondria were isolated from mDPC6T cells using a mitochondrial isolation kit (BioVision, USA). After the mitochondria were discarded, the cytoplasm was prepared to isolate cytosolic mtDNA using a genomic DNA miniprep kit (Axygen, USA). PCR quantification was then carried out to analyze mitochondrial DNA and nuclear DNA in the cytoplasm. Mitochondrial DNA was marked by tRNA-LeuUUR, while nuclear DNA was characterized by β-microglobulin genes. The ratio of mtDNA to nDNA in the cytoplasm represented the copy number of cytosolic mtDNA.

Total genomic DNA was extracted using a Genomic DNA Miniprep Kit (Axygen) following the manufacturer’s instructions. The DNA quality was then evaluated by agarose gel electrophoresis and a BioPhotometer Plus spectrophotometer (Eppendorf, Germany).
Subsequently, the two samples were sonicated to produce DNA fragments ranging from 100 to 500 bp. After end repairing, phosphorylating and A-tailing with Paired-End DNA Sample Prep kit (Illumina, USA), the DNA was ligated to an Illumina sequencing primer adaptor. Then the fragments were used for methylated DNA immunoprecipitation (MeDIP) enrichment using a Magnetic Methylated DNA Immunoprecipitation kit (Diagenod, Belgium) following the manufacturer’s recommendations and the qualifying DNA was used for PCR amplification. Then bands between 220 and 320 bp were excised from the gel and purified with a QIAquick Gel Extraction Kit (Qiagen, Germany). The products were quantified with a Quant-iT™ dsDNA HS Assay Kit (Invitrogen, USA) using an Agilent 2100 Analyzer (Agilent Technologies, USA). Following qPCR qualification, DNA libraries were sequenced on the Illumina HiSeq 2000 (Illumina, CA, USA) to generate paired-end 50-bp reads by the Beijing Genomics Institute (BGI, China).

Guide RNAs were designed using the online CRISPR design tool (http://crispr.mit.edu/) and then cloned into the BbsI‐digested plasmids (pSpCas9n) containing the entire guide RNA scaffold. After transfection, the genomic DNA of IPEC‐J2 cells were extracted using Genomic DNA Miniprep kit (Axygen, AZ, USA). The genomic region flanking the MyD88 target site was amplified using polymerase chain reaction (PCR). The products underwent a re‐annealing process to facilitate heteroduplex formation. After re‐annealing, the products were treated with T7 Endonuclease I (T7E I) following the manufacturer's recommended protocol.
Isolation of clonal cell lines that were confirmed by T7E I were performed by serial dilutions. Detection of genomic microdeletions was performed by PCR sequencing. Off‐target activity was analysed by deep sequencing and the Blast search (http://blast.ncbi.nlm.nih.gov/Blast.cgi).

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.
