Total RNAs were isolated from patient samples and human cells with Trizol reagent, and quantified using a NanoDrop spectrophotometer (Thermo Scientific, Rockford, IL). Regular and stem-loop reverse transcription of mature miR-1291 were conducted as described previously [30 (link), 60 (link)]. RT-qPCR was performed on a MyIQ real-time PCR system (Bio-Rad, Hercules, CA). The cycle number (CT) at which the amplicon concentration crossed a defined threshold was determined for each individual miRNA. The relative level of each analyte over internal standard (glyceraldehyde-3-phosphate dehydrogenase, or U6) was calculated as 2−ΔΔCT, where ΔΔCT = ΔCT treatment group (analyte – internal standard) – ΔCT control group (analyte – internal standard).

Total RNA was extracted from MCF-7 and MDA-MB-231 cells, respectively, using the RNeasy MinElute Cleanup Kit (Qiagen GmbH, Hilden, Germany). cDNA was synthesized with SuperScript III Reverse Transcriptase (Life Technologies) and random hexamer primers (200 ng; #SO142, Fisher Scientific GmbH, Schwerte, Germany). SYBR Green real time PCR was carried out with 13 μl SYBR Green Master mix (ABsolute QPCR SYBR Green Mix, Fisher Scientific), 10 nM primer and 15 ng cDNA in a final reaction volume of 20 μl. All samples were run in duplicate. RPL27 was used as a reference gene. The characteristics of the primers are shown in Table S1.
Thermal cycling was performed on a MyiQ™ real-time PCR system (Bio-Rad Laboratories GmbH, Munich, Germany) with the following protocol: 95 °C for 10 min, 45 cycles at 95 °C for 30 sec → 60 °C for 30 sec → 70 °C for 30 sec, and 72 °C for 5 min. To check for specificity of the primers the temperature was ramped up from 55 °C to 95 °C (at the rate of 0.5 °C/s). Melting curve analysis was performed according to the dissociation stage data and reactions with a single peak at the expected Tm were considered for further analysis. Calculation of the gene expression level was carried out with the program Rest 2005 (Corbett Research, Sydney, Australia and Technical University of Munich, Germany) using the comparative threshold method 2−ΔΔCT.

Cells were washed with ice-cold sterile PBS. Trizol® Ambion (Madrid, Spain) protocol was applied for RNA extraction (1 mL/plate sample) [28 (link)]. RNA was quantified by ND-1000 (Nanodrop Technologies; Madrid, Spain) and the RNA integrity number (RIN) was calculated. RNA was retrotranscripted to cDNA with Transcriptor First-Strand DNA cDNA Synthesis (Roche) following the manufacturer’s instructions. qPCR assays were carried out with 5 µL cDNA + 10 µL SYBR® Green PCR Master Mix cocktail (Applied Biosystems) + 250 nM forward and reverse primers (Table 2). RLPLP0 was chosen as a house-keeping endogenous control for normalization purposes. Three RNA pools of four donors each were evaluated for each condition, by triplicate. qPCR reaction was carried out in MyIQ RealTime PCR System (BioRad). Result analysis was conducted with IQ5 program (BioRad), following the ΔΔCt method.

For RT-qPCR analysis, we synthesized first-strand cDNAs from 5 μg total RNA using SuperScript III reverse transcriptase (Invitrogen, Carlsbad, CA, USA) using the provided protocol. A 1:40 dilution of the cDNAs was used for RT-qPCR. The amplification parameters were as follows: 15 min of denaturation and enzyme activation at 95 °C; followed by 40 cycles of 95 °C for 5 s, 60 °C for 15 s, and 72 °C for 30 s; with a final step performed at 65–95 °C (1 °C/s) for melting curve analysis. The amplified signals were detected using a MyiQ real-time PCR system (Bio-Rad Laboratories, Hercules, CA, USA) using SYBR Premix Ex TaqTM (TOPrealTM qPCR 2X PreMix, www.enzynomics.com, Yuseong-gu, Daejeon, Korea). The data were normalized based on the expression of rice UBIQUITIN5, and the relative gene expression was analyzed using the 2ΔΔCt method or the 2ΔCt method.

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.
