Transfection of cells was performed by using the FuGENE ® HD transfection reagent (Promega, Mannheim, Germany) according to the manufacturer's instructions.
For the luciferase reporter assay, HCT116 cells were seeded into a 24-well plate (62,500 cells per well) in a total volume of 0.5 ml/well of cell culture medium and cultured overnight. Cells were then transfected with FuGENE ® HD transfection reagent using a total of 0.5 g of plasmid DNA (transfection mixture per well: 0.05 g of promoter reporter plasmid, 0.45 g of expression plasmid(s), 1.25 l FuGENE ® HD transfection reagent and 25 l cell culture medium without FCS).
To measure luciferase activity, cells were collected at given time points after transfection by lysing in cell culture lysis reagent (Promega) and measured with the Luciferase Assay System (Promega) following the manufacturer's recommendations.
For Western blot analysis, cell lysates were centrifuged at 13,000 × g to remove cell debris. The protein content was determined with the Bradford method using the BioRad protein assay reagent (BioRad, Munich, Germany). Protein extracts were immediately used for Western blot analysis or stored at -20 • C.

Three different siRNA duplexes used for KLF2 knockdown (Table 2) were designed and synthesized by Genepharma company (Shanghai, China). The 152 pmol given siRNA duplexes or the mixtures of 152 pmol given siRNA duplexes and 2 μg pCMV-myc-KLF2 were transfected into the chicken preadipocytes cultured in one well of the 6-well culture plate using FuGENE HD transfection reagent (Promega). After transfection for 48 h, semi-quantitative RT-PCR and western blot was employed to detect the knockdown efficiency of these siRNA duplexes. Only the siRNA duplexes with the highest knockdown efficiency were used for subsequent studies. Briefly, an amount of 152 pmol given siRNA duplexes was transfected into the chicken preadipocytes cultured in each well of 6-well culture plate using FuGENE HD transfection reagent (Promega). After transfection for 48 h, western blot and real-time RT-PCR were recruited to study the effect of KLF2 knockdown on C/EBPZ expression.

HEK293 cells were used in the transient transfection system, as previously described64 . In brief, 20,000 cells per well were plated in 96-well flat-bottom plates. For the assessment of AhR agonistic activity, cells were transfected with pGud-Luc21 and pTK-Renilla (Renilla luciferase under control of constitutively active thymidine kinase promoter, Promega, Madison, WI) using Fugene-HD Transfection Reagent (Promega, #E2311) as suggested by the manufacturer 24 h after plating. After 24 h, transfected cells were incubated with DMEM supplemented with 10% of patient serum in duplicates. Luciferase activity was analyzed 24 hours later using the Dual Luciferase Reporter System (Promega, #E1980). Firefly luciferase activity was normalized to Luciferase activity to determine relative AhR activity. Results are represented as percent normalized AhR activity relative to control samples.
For the assessment of CD274 promoter activity, cells were transfected with pEZX-PF02 (eGFP under control of CD274 promoter) using Fugene-HD Transfection Reagent (Promega, #E2311) as suggested by the manufacturer. After 24 h, transfected cells were stimulated with the indicated stimuli.

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.
