Total RNA from cells treated with CpG-ODN and LPS was purified using the FastGene RNA
Premium Kit (Nippon Genetics Co., Ltd., Tokyo, Japan). cDNA was prepared by reverse
transcription of 100 μg total RNA per sample using SuperScript IV reverse transcriptase
(Thermo Fisher Scientific). Equal volumes of cDNA were used to quantify various immune
response-related cytokine factors by qRT-PCR using the StepOne real-time PCR system
(Applied Biosystems, Foster City, CA, USA) and KOD SYBR qPCR Mix (Toyobo Co., Ltd., Osaka,
Japan) with specific primers. The nucleotide sequences of the primers that were used are
listed in Table 2. qRT-PCR was performed in
duplicate. The relative expression levels of each target gene were calculated using the
ΔΔCt method (Livak and Schmittgen,
2001
) and normalized against β-actin expression.

Check if the same lab product or an alternative is used in the 5 most similar protocols
RNA-Seq results in the control fibroblasts (NoC) and ciBAs (RoFB) have been previously reported36 (link). In this study, total RNA was prepared from Capsaicin-treated ciBAs (RoFB + Capsaicin) derived from HDF38 by FastGene RNA Premium Kit (Nippon Genetics, Tokyo, Japan). RNA integrity number (RIN) values were over 9 in all the RNA samples. The library was prepared by TruSeq stranded mRNA LT Sample Prep Kit (Illumina, CA, USA), following the manufacturer’s low sample (LS) protocol. A 100 bp paired-end sequencing was performed by NovaSeq 6000 System (Illumina). Trimmed reads were mapped to a reference genome (NCBI GRCh37) with HISAT2. After the read mapping, StringTie was used for transcript assembly. After the assembly, the abundance of gene/transcript was calculated from the read counts and normalised as fragments per kilobase of transcript per million mapped sequence reads (FPKM). For identification of DEGs, statistical analysis was performed by FC and exact test using edgeR per comparison pair. Significant results satisfying the conditions of |FC|≥ 2 and the exact test p value < 0.05 were selected. If more than one read count value was zero, it was not included in the analysis.

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.
