MH7A cells or primary synovial cells were pretreated with of CIN for 2 h, and then incubated for another 6 h with 10 ng/mL LPS. Total RNAs were isolated using the commercial total RNA miniprep kit (Axygen, USA), according to the manufacturer’s instructions. Each sample was reversely transcribed using the cDNA synthesis kit (TaKaRa, China), by following the manufacturer’s protocol. The primer sequences were used for real-time PCR as shown in Table 1. Real-time PCR was performed using SYBR Green PCR Premix Ex Taq II reagents (TaKaRa) on a Light Cycler 480 II real-time system (Roche, USA), with GAPDH serving as house-keeping gene for normalization [25 (link)].

Total RNA was extracted from PBMCs or cultured cells using M5 Hiper Universal Plus RNA Mini Kit (Mei5 Biotechnology, China). cDNA was synthesized using the cDNA synthesis kit or Mir-X miRNA First-Strand Synthesis Kit (both TaKaRa, Japan). Primers for qRT-PCR were designed via a public resource named PrimerBank (https://pga.mgh.harvard.edu/primerbank/) and synthesized by Sangon Biotech, which are listed in Table 3. qRT-PCR amplification was performed using SYBR Green PCR Premix Ex Taq™ II reagents (TaKaRa, Japan) with the Quant Studio 6 FlexI real-time PCR system (Applied Biosystems, USA), following the protocols from the commercial kits. Expression levels of tested genes were determined with the 2-ΔCt or 2-ΔΔCt method based on the endogenous control (GAPDH or U6).

MH7A cells were seeded in 6-well plates at 1 ​× ​106 ​cells/well for 24 ​h. The cells were pretreated with AG490/GEN (Sigma–Aldrich) at indicated concentrations for 2 ​h and then stimulated with TNF-α (10 ​ng/mL; R&D Systems, Minneapolis, MN, USA) or IL-6 (50 ​ng/mL; Sigma–Aldrich) for 24 ​h. According to the manufacturer's instructions, total RNA of the cells was extracted using the commercial total RNA miniprep kit (Corning, Inc., Axygen, NY, USA). Then, each RNA sample was reverse transcribed using a complementary DNA (cDNA) synthesis kit according to the manufacturer's protocol. qPCR analysis was performed using SYBR Green PCR Premix Ex Taq II reagents (Takara Bio Inc., Kusatsu, Japan) on a Light Cycler 480 II real-time system (Roche, Mannheim, Germany). Glyceraldehyde 3-phosphate dehydrogenase (GAPDH), a house-keeping gene, was used for normalising the result of qPCR.

Cartilages of the right knee were obtained and stored in liquid nitrogen. Total RNA of the cartilage cells was isolated using a commercial total RNA mini-prep kit (Axygen, USA) according to the manufacturer’s instructions. Each sample was reverse transcribed using a cDNA synthesis kit (TaKaRa, Japan) according to the manufacturer’s protocol. Real-time PCR (RT-PCR) analysis was performed using SYBR Green PCR Premix Ex Taq II reagents (TaKaRa, Japan) on a Light Cycler 480 II real-time system (Roche, USA). PCR primer sequences are listed in Table 1. The housekeeping gene GAPDH was used for normalisation.

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.
