RNA was extracted using the miRCURY™ RNA Isolation Kit – Cell & Plant (QIAGEN, Hilden, Germany) and miScript II RT Kit (QIAGEN) following the manufacturer's protocols. For cDNA synthesis 1 μg of RNA was used. Real-time PCR amplification and analysis was performed using a LightCycler 480 with DyNAmo ColorFlash SYBR Green (Roche, Mannheim, Germany) and the primers listed in Supplementary Table S2. For normalization, HPRT1, YWHAZ and RPS29 mRNAs were used as controls. miRNA quantification was performed by using the miRNA miScript Primer assay and miScript SYBR Green PCR Kit (QIAGEN). U6, SNORD61 and SNORD95 (QIAGEN) were used as controls. Calculations of relative changes in gene expression were done using the ΔΔ cycle threshold (Ct) method (25 (link)). For statistical analysis the unpaired two sample Student's t-test was applied, using the software GraphPad prism V 7.03 (GraphPad Software, San Diego, USA).

RNA from PBMCs was isolated with miRCURYTM RNA Isolation Kit-Cell & Plant (Exiqon, Aarhus, Denmark) following manufacturer’s instructions. RNA was quantified with a NanoDrop 2000 and integrity was assessed in a 2% agarose gel. A total of 500 µL of RNA were retro-transcribed with PrimeScript Reverse Transcription Kit (Takara, Saint-Germain-en-Laye, France) according to manufacturer’s protocol and resulting cDNA was used as a template for amplifying MDM2 and DENND5B genes by RT-qPCR with FastStart Universal SYBR Green Master. Primers used for MDM2 amplification were 5′-CCCAAGACAAAGAAGAGAGTGTGG-3′ and 5′-CTGGGCAGGGCTTATTCCTTTTCT-3′ forward and reverse primers, respectively. To amplify DENND5B, we used 5′-CTCCAGCGATACAACTCCTATGA-3′ and 5′-GTGGATATAGCTTTCAAGTGGCA-3′ forward and reverse primes, respectively. Relative gene expression was calculated with the 2−ΔΔCt method using the quadratic average of RN18S and RPLP0 CTs as references.

Total RNA was extracted using the miRCURYTM RNA Isolation Kit - Cell & Plant (Exiqon, Vedbæk, Denmark) according to the manufacturer′s protocol.
The concentration of isolated total RNA was determined using a NanoDrop Lite spectrophotometer (Thermo Scientific, Hudson, NH, USA). The total RNA profiles were
visualized by using an Agilent 2100 bioanalyzer (Agilent Technologies, Palo Alto, CA, USA) and Agilent RNA6000 Pico Kit (Agilent Technologies). In addition, the
miRNA (10–40 nt) concentrations were analyzed by using an Agilent 2100 bioanalyzer (Agilent Technologies) and Agilent Small RNA Kit (Agilent Technologies)
according to the manufacturer′s protocols.

EV RNA extraction was performed using the miRCURY RNA Isolation Kit - Cell & Plant (#300110, Exiqon) following the manufacturer’s instructions. In brief, exosome pellet was lysed with the provided lysis solution supplemented with 96–100% ethanol, and the mixture was loaded to the column. The EV RNA was washed and eluted with 15–50 µL of RNase-free water. The extracted RNA concentration was calculated by Quant-IT RiboGreen (Invitrogen; Thermo Fisher Scientific, Waltham, MA, USA). RNA size was confirmed using Agilent RNA 6000 Pico Kit and Small RNA Kit on Agilent 2100 Bioanalyzer (Agilent Technologies, Waldbronn, Germany).

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.
