Total RNA was extracted with a miRVana isolation kit (Thermo Fisher) and reverse-transcribed to cDNA with a QuantiTect reverse transcription kit (Qiagen) according to the manufacturer’s instructions. cDNA samples synthesized from 1 μg of total RNA were subjected to RT-qPCR with the Applied Biosystems Quant Studio 7 Flex instrument using the iTaq SYBR Green Supermix (Bio-Rad). Relative gene expression was calculated using the ΔΔCT method normalizing the expression to that of a stable reference gene (GAPDH or as stated). We assumed a primer efficiency of 100% (±10%), according to manufacturer’s guidelines. The primers are listed in Table S3.
TaqMan gene expression assays (Fig. 4) were conducted using probes from ThermoFisher listed in Table S4. They were used following manufacturer’s protocols and run on an Applied Biosystems Quant Studio 7 Flex instrument. Data were analyzed as described above.

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.
