RNA was extracted using trizol/chloroform isolation followed by Ambion mirVana kit (AM1560). Total RNA was reverse-transcribed using random primers (Amersham Biosciences), and β-actin primers were used to control for cDNA concentration in a separate PCR reactions for each sample. LightCycler Fast Start DNA Master SYBR Green Mix (Roche) was added to each PCR reaction along with cDNA and 1 pmol primer in a total volume of 10 µl. qPCR was performed on a eppendorf realplex2 mastercycler using the real-time primers provided, according to instructions. Ct values were converted to fold expression changes (2−ΔΔCt values) following normalization to β-actin. Primer sequences are listed below.

Quantitative Gene Expression Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
Quantitative reverse transcriptase polymerase chain reaction (qRT-PCR) was performed on genes of interest that were up-regulated via microarray analysis. Total RNA was reverse transcribed using random primers (Amersham Biosciences, Little Chalfont, UK), with GAPDH primers used to control for cDNA concentration in separate PCR reactions for each sample. Primers for GADPH, ADAMTS1, LOXL4, BMP2, SMAD7, ITGA2, and TRPV4 were designed using Primer3 and are shown in Supplemental Table 5. To each PCR reaction (triplicates), LightCycler Fast Start DNA Master SYBR Green Mix (Roche, Basel, Switzerland) was added, along with cDNA and 1pmol primer in a total reaction volume of 10μl. Ct values were converted to fold expression changes (2–ΔΔCt values) after normalization to GAPDH expression levels.

Quantifying DNA Methylation Cleavage

The extent of cleavage by MSREs was determined using qPCR detection of spiked-in controls. A master mixture (19 μL) containing 2 mM MgCl2,LightCycler FastStart DNA Master SYBR Green mix (Roche Diagnostics Canada, Laval, QC, Canada), 14.4 μL of nuclease-free water and 1 μL of cleaved sample (template) was divided into three fractions to which 0.25 μM of each forward and reverse primer designed to target the appropriate control template was added (see Additional file
2: Table S1). Each qPCR run also included a positive control (non-digested spiked-in, 1/1000 dilution) and negative control (no template). The qPCR conditions were as follows: initial denaturation was carried out at 95°C for 10 minutes, followed by 50 amplification cycles at 95°C for 5 seconds, 52°C for 5 seconds and 72°C for 20 seconds. Melting curve analysis was performed for 1 cycle with a ramp rate of 0.2°C per second, starting at 94°C for 5 seconds, 72°C for 30 seconds, and back to 94°C for 0 seconds, and cooling at 40°C.
Amplicon specificity was determined from the shape of the melting curve and the difference in cycle threshold (Δ Ct) between methylated (MSRE cleavage protected) and unmethylated (MSRE cleavage unprotected) templates was used to calculate cleavage efficiency. The DNA samples were then precipitated by ethanol, washed and dissolved in 10 μL of nuclease-free water.

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.
