Gene Expression Analysis in IFNγ, Bradykinin, and LPS-Treated HUVECs

Check if the same lab product or an alternative is used in the 5 most similar protocols
HUVECs were cultured in 24-well plates to 100% confluency in Comp-MCDB medium, then treated with IFNγ (20 ng/mL), bradykinin (20 μM), or LPS (100 ng/mL) for 2 or 24 h. RNA isolation was carried out using the illustra™ RNASpin RNA Isolation Kit (GE Healthcare, Chicago, CA, USA) according to the manufacturer’s protocol. RNA–cDNA transcription was performed with the Tetro cDNA Synthesis Kit (Bioline, Essex, UK). SensiFAST SYBR Master Mix—No ROX Kit (Bioline) was used for the quantification of cDNA using a Rotor-Gene Q (Qiagen, Hilden, Germany) real-time PCR cycler. Primers (Table 2) were designed using the NCBI Primer-BLAST primer design tool and synthetized using IDT (Coralville, IA, USA). The purity and size of PCR products were checked by sequencing (sequencing was performed by Biomi Ltd., Gödöllő, Hungary) after the first use of each primer pair and by high-resolution melting curve analysis for each measurement.
Quantification was performed using the Rotor-Gene Q Pure Detection 2.1.0 software (Qiagen, Hilden, Germany), and values of interest were normalized with that of β-actin.

DNA Genotyping from Blood and Saliva

DNA purification from whole blood and saliva samples was performed manually using a QIAamp® DNA Blood Mini Kit (Qiagen Ltd., Manchester, UK), following the manufacturer’s guidelines. DNA samples were then stored at 4°C until subsequent genotyping.
Real-time polymerase chain reaction was performed (Rotor-Gene Q, Qiagen) to establish the genotypes of each SNP for each participant. Each 10 μL reaction volume contained 5 μL Genotyping Master Mix (Applied Biosystems, Foster City, USA), 3.5 μL nuclease-free H2O (Qiagen), 0.5 μL genotyping assay (Applied Biosystems), plus 1 μL DNA sample. Both negative [1 μL nuclease-free H2O (Qiagen) replaced the DNA template] and positive controls were included in each RT-PCR run, which used the following protocol: denaturation at 95°C for 10 min, followed by 50 cycles of incubation at 92°C for 15 s, then annealing and extension at 60°C for 1 min. Genotypes were determined using Rotor-Gene Q Pure Detection 2.1.0 software (Qiagen). All samples were analysed in duplicate and there was 100% agreement between genotype calls for samples from the same participant. Genotyping was performed in accordance with published genotyping and quality control recommendations [44 (link)] and all SNPs were genotyped according to the forward DNA strand.

Genotyping of NOS3 Polymorphism from Whole Blood

Check if the same lab product or an alternative is used in the 5 most similar protocols
A blood sample was drawn into a 10‐ml EDTA vacutainer (BD Vacutainer Systems) from a superficial forearm vein. The whole blood was aliquoted into 2‐ml tubes (Eppendorf AG) and stored at −80°C until subsequent analysis. DNA purification from whole blood samples was performed manually using a QIAamp DNA Blood Mini Kit (Qiagen Ltd.), following the manufacturer's guidelines. DNA samples were then stored at 4°C until subsequent genotyping. Real‐time polymerase chain reaction was performed (Rotor‐Gene Q, Qiagen) to establish the genotypes of each SNP for each participant. Each 10 μl reaction volume contained 5 μl Genotyping Master Mix (Applied Biosystems), 3.5 μl nuclease‐free H2O (Qiagen), 0.5 μl NOS3 rs2070744 genotyping assay (Applied Biosystems), plus 1 μl DNA sample. Both negative [1 μl nuclease‐free H2O (Qiagen) replaced the DNA template] and positive controls were included in each RT‐PCR run, which used the following protocol: denaturation at 95°C for 10 min, followed by 50 cycles of incubation at 92°C for 15 s, then annealing and extension at 60°C for 1 min. Genotypes were determined using Rotor‐Gene Q Pure Detection 2.1.0 software (Qiagen). All samples were analyzed in duplicate, and there was 100% agreement between genotype calls for samples from the same participant.

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.
