ECs were collected and total RNA was obtained with mirVANA miRNA kit. The RNA was transcribed using TaqMan® Advanced miRNA cDNA Synthesis Kit (Applied Biosystems; CA, EU) protocol. All assays were performed in duplicates for the differentially expressed miRNAs including miR-126-5p and -3p, let7g-5p, miR-103a-3p and miR-30b-5p (Life Technologies; CA, EU) (n = 5). For normalization miR-423-3p and let-7a-5p means were used as endogenous miRNA controls.26 (link) The amplification was performed in ABI PRISM 7900HT Sequence Detection System (Applied Biosystems; CA, EU) in 384-well plates. The amplification curves were analysed using the Applied Biosystems Sequence Detection System 2.4.1 software. Ct values were obtained and processed by the standard curve method and normalized with the endogen. To obtain fold difference vs. control the ratio sample/control was calculated. Networks, functional analyses, detection of miRNAs targets and interactions were generated by Ingenuity Pathway Analysis software (IPA) and RNA hybrid tool.

3T3-L1 cells were transfected with mirVana miR-106b (LifeTechnology MC10067), let 7g-5p (LifeTechnology MC11758), 330-3p (LifeTechnology MC10732), 19b-5p (LifeTechnology MC13042), 142-3p (LifeTechnology M C10398),125a-5p (LifeTechnology MC12561), 331-3p (LifeTechnology MC10881) mimics or miR-106b or Let7g antagomirs (AM10067, MH11758 respectively). 72 h after transfection, 3T3-L1 cells were evaluated for 2-DG uptake and mRNA expression in lysates by RT-qPCR. 3T3-L1 cells were also transfected with pre-miR-106b siRNA sense oligonucleotides 5’-CCU AAU GAC CCU CAA GCC GUU-3 and antisense 5’-CGG CUU GAG GGU CAU UAG GUU-3’ then exposed to VD( + ) HSC or VD(-) HSC-recipient peritoneal macrophage media for 72 h before assessment of pre-miR-106-5p or mature miR-106b-5p. Peritoneal macrophages from VD( + ) HSC or VD(-) HSC recipients were transduced with lentivirus containing sense either Jarid2-siRNA (LifeTechnology 4390771), Ppargc1a-siRNA (LifeTechnology, AM16708), or control-siRNA (LifeTechnology AM461) for 48 h and mRNA expression was determined as previously described81 (link).

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.
