Total RNAs were extracted from liquid nitrogen-powdered tissues or cultured cells by using RNAiso Plus reagent (Takara, Dalian, China), according to the manufacturer’s specifications. After roughly qualified degradation and contamination by using 1.5% agarose gel electrophoresis, and concentration by utilizing NanoDrop 2000c Spectrophotometer (Thermo-Fisher Scientific, Waltham, UK). Subsequently, the qualified RNAs (~1 mg) were reverse-transcribed into cDNA for mRNA or miRNA assay using the PrimeScript™ RT reagent Kit with gDNA Eraser or miRNA PrimeScript RT reagent Kit (Takara, Japan) separately. Then we accurately quantified the expression of genes by real-time PCR (qPCR) in a Bio-Rad CFX96 system (Bio-Rad, Shanghai, China) with SYBR Premix Ex Taq TM II (Takara, Dalian, China). More than three samples were collected per treatment, and each was technically tri-replicated in the qPCR assay. We employed 2−ΔΔCt method to scale the relative RNA levels of the target genes with GAPDH (Glyceraldehyde-3-Phosphate Dehydrogenase) as the internal control for mRNA or circRNA, U6 for miRNAs. These primers were detailed in Supplementary Table S1.

Following the manufacturer's instruction, total RNAs were extracted from tissues or cultured cells using RNAiso Plus reagent (TaKaRa, Japan), and roughly quali ed by using 1.5% agarose gels electrophoresis and NanoDrop 2000c Spectrophotometer.
Then the quali ed RNAs (~1 mg) were reversely transcribed into cDNA by using the PrimeScript™ RT reagent Kit with gDNA Eraser or miRNA PrimeScript RT reagent Kit (Takara, Japan) separately for mRNA or miRNA assay. Then according to the manufacturer's guide, RNA levels of target genes in these cDNA were accurately measured by using real-time PCR (RT-qPCR) in the Bio-Rad CFX96 system (Bio-Rad, USA) with SYBR Premix Ex TaqTM II (Takara, Japan). Each treatment performed at least triply three independent times, and each sample triplicates in qPCR. Moreover, to enhance the accuracy, three housekeeping genes in goat ACTB (Actin Beta), SDHA (Succinate Dehydrogenase Complex Flavoprotein Subunit A), and PGK1(Phosphoglycerate Kinase 1)) and mouse (ACTB, GAPDH, and Hprt (Hypoxanthine Phosphoribosyltransferase 1)) were used as an internal control. The 2 -△△Ct or 2 -△Ct methods were employed to calculate the relative RNA levels of target genes. The detailed information for primers was listed in Supplementary Table 1.

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.
