Knockdown of Sirt1 and Trim72 in Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
Sirt1 siRNA (m) (sc-20987), Trim72 siRNA (m) (sc-154670), and control siRNA (sc-36869) were bought from Santa Cruz (Santa Cruz, CA, USA). Cells were transfected using LipofectamineTM 3000 (Thermo Fisher, USA) to knockdown the genes of Sirt1 and Trim72. After treating the cells with drugs, they were analyzed using Western blotting, immunofluorescence, β-galactosidase staining, ROS staining, and fluo-3AM staining.

siRNA Knockdown of Wnt Genes in MSCs

Check if the same lab product or an alternative is used in the 5 most similar protocols
siRNAs specific for mouse Wnt3a (sc-41109), Wnt5a (sc-41113) and control siRNA (sc-36869) with scrambled sequences were purchased from Santa Cruz. In each transfection, 0.1 to 0.2 μM siRNAs were introduced into MSCs using the Lipofectamine 2000 kit (Invitrogen, USA). The efficiency of transduction was determined by detecting the rate of FITC-positive cells and the mRNA expression of specific genes.

Silencing YY1 Transcription Factor in Ramos Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
Ramos cells were transfected with siRNA for YY1 and corresponding irrelevant controls by liposomes. Cells were treated with 30 nM siRNA YY1 (YY1 siRNA (h) SC-36863) or control siRNA (SC-36869) (Santa Cruz Biotechnology, Inc.) and transfected using Lipofectamine 2000 (Invitrogen, Thermo Fisher Scientific, USA) following the manufacturer's instructions. The transfected cells were incubated at 37° C and 5% CO2 for 48 hrs. Subsequently, a western blot was performed to determine the expression of YY1 and KLF4 in cells treated with siRNA.

Knockdown of iNOS and 15-LOX-2 in EOC 20 Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
A pool of three target-specific 19-25 nt siRNAs designed to knock down iNOS and 15-LOX-2 expression in the EOC 20 cells was utilized. Control siRNA (sc-36869) and iNOS- (NOS2 siRNA (m): sc-36092) and 15-LOX-2-siRNA (15-LOX-2 siRNA (m): sc-45627) were designed and synthesized by Santa Cruz Biotechnology, Inc. Transfection of the control-siRNA and the target-siRNA was performed using Lipofectamine RNAi Max (Invitrogen) following the manufacturer’s instructions. EOC 20 cells were seeded onto 6 well-plates at 1~2x105 cells /1 ml /well for incubations up 7 h, then the transfection mixture was removed and cells were switched to DMEM supplemented with 10% FBS for 24 h. Knock down efficiency was assessed by western blot analysis using the following antibodies: anti-iNOS (ab178945, Abcam, 1:500), anti-15-LOX-2 (sc-67143, Santa Cruz, 1:500), horseradish peroxidase (HRP)-conjugated anti-rabbit IgG H&L (Sigma, A0545, 1:2000) secondary antibody, and anti-β-actin-peroxidase antibody (ThermoFisher, Cat # A3854,1:5000). To assess the effect of KD on ferroptosis cells were plated in 24-well plate (15000 - 20000 cells per well), incubated with RSL3 and cell death was assessed by measuring released LDH activity.

In Vitro IDD Model Establishment

Check if the same lab product or an alternative is used in the 5 most similar protocols
Human NP cells were purchased from American Type Culture Collection (ATCC) and cultured in Dulbecco's Modified Eagle Medium (DMEM)/F12 medium (with 10% fetal bovine serum and 1% penicillin‐streptomycin) at 37°C using a 5% CO2 incubator. Cells were cultured in monolayer and the 2−3 generations of cells were used in the following experiments. Experiments were performed for three times.
To construct an in vitro model of IDD, we treated NP cells with 10 ng/ml of LPS for 24 h.
The lncRNA MAGI2‐AS3 sequence was synthesized based on the lncRNA MAGI2‐AS3 sequence and then subcloned into the pcDNA3.1 vector (MAGI2‐AS3‐plasmid; Shanghai GeneChem Co., Ltd.). The empty pcDNA3.1 vector was used as a control (control‐plasmid). For IL‐10 knockdown, the control‐siRNA (sc‐36869) and IL‐10‐siRNA (sc‐39634) were purchased from Santa Cruz Biotechnology. NP cells were transfected with control‐plasmid, MAGI2‐AS3‐plasmid, control‐siRNA, IL‐10‐siRNA, mimic control (Shanghai GenePharma), miR‐374‐5p mimic (Shanghai GenePharma), inhibitor control (Shanghai GenePharma), miR‐374‐5p inhibitor (Shanghai GenePharma), MAGI2‐AS3‐plasmid+mimic control, MAGI2‐AS3‐plasmid + miR‐374‐5p mimic, miR‐374‐5p inhibitor+control‐siRNA, or miR‐374‐5p inhibitor + IL‐10‐siRNA using Lipofectamine 2000 reagent (Thermo Fisher Scientific, Inc.) at 37°C for 24 h as per the manufacturer's protocol.

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.
