Nematodes were collected in 1 ml Trizol, and lysed by freeze-thawing. RNA was extracted from lysates with the Qiagen RNeasy Mini Kit (Qiagen), DNAse-treated (ThermoScientific), and used for cDNA synthesis with the Maxima H Minus First Strand cDNA Synthesis Kit (ThermoScientific). qRT-PCR was performed with the KAPA SYBR FAST qPCR Master Mix (KAPA Biosciences) on the LightCycler 480 II real-time thermocycler (Roche Applied Science). Raw values were normalized to each of three control genes (act-1, nhr-23, and ama-1); the average of the normalized values was then used for analysis [75 (link)]. Primer sequences used in qRT-PCR are presented in Additional file 3: Table S3.

RNA Extraction and cDNA Synthesis for Gene Expression Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
Prior to RNA extraction, cells were harvested, centrifuged and flash frozen as pellets. For measuring the expression of cell surface markers, cells were harvested at 70-80% confluency. For measuring expression of adipogenic genes, cells were harvested at the end of the differentiation assay. Total RNA was extracted using TRIzol Reagent (Life Technologies) according to the manufacturer’s instructions. RNA quality was confirmed via agarose gel electrophoresis, and 1 μg of total RNA was subsequently DNAse-treated (Thermo Scientific) and used for first-strand cDNA synthesis using Oligo(dT) primers and RevertAid First Strand cDNA Synthesis Kit (Thermo Scientific) according to the manufacturer’s instructions.

Quantitative Gene Expression Analysis

RNA was isolated from the cells using TRI Reagent (Sigma-Aldrich) and DNase treated (Thermo Fisher Scientific, USA) according to the manufacturer’s guidelines. RNA (250 ng-1.5 μg) was reverse transcribed (RT) using MMLV Reverse Transcriptase (Thermo Fisher Scientific, USA) using random decamers except in the case of directional-RT (sense or antisense pRNA) in which a gene specific primer (100 pM) was used.
Real-time RT-PCR (qRT-PCR) was done on Rotor-Gene 6000 real-time PCR machine (Corbett Research, Australia) using indicated gene specific primers (S2 Table). Multiple reference genes i.e. 18S, POLR2A, PPIA, and β-actin were used for accurate quantification of gene expression using the Relative Expression Software Tool which is available online at http://www.genequantification.de/rest.html. This software applies a mathematic model that takes into account the variable PCR efficiencies of the target gene and reference genes. Thus using multiple reference genes improves the reliability of the assay than using the conventional single reference gene normalization method[28 (link)].

The replicon was further modified by insertion of modified sequences in the nontranslated 3′ UTR as described in Table 1. Replicon plasmids were linearized using NotI, and RNA transcripts were synthesized in vitro using T7 RNA polymerase (MEGAscript T7; Thermo Fisher Scientific) for 4 h. pTK-Ren (Promega) expressing Renilla luciferase was cotransfected as a transfection control. pTK-Ren was linearized using XbaI. RNA transcripts were DNase treated (Thermo Fisher Scientific) and cleaned with a RNA Clean and Concentrator column (Qiagen). RNA integrity was confirmed on agarose gels, and the concentration was determined with Qubit fluorometric quantitation (Thermo Fisher Scientific).
Cells were seeded at 2 × 104 cells per well in 96-well plates and transfected with 50 ng of replicon and 10 ng of pTK-Ren using the transfection reagent Lipofectamine 2000 (Thermo Fisher Scientific). At the 6 h posttransfection, cells were washed with phosphate-buffered saline (PBS) and harvested in passive lysis buffer (Promega), and the luciferase activities were measured using the dual luciferase reagent kit and GloMax multidetection system (Promega). The firefly luciferase readings were normalized to the Renilla value for each sample. In some formats investigating effects of gene KO, luciferase expression was further normalized to that of the parental WT A549 cell line control.

Total RNA was extracted using Trizol (Invitrogen) following the manufacturer’s instructions. Four micrograms of total RNA was DNase treated (Ambion Inc., Austin, TX) and converted to cDNA by the High Capacity cDNA Archive Kit (Applied Biosystems, Foster City, CA). PCR was performed in 96-well plates. Assays-on-Demand Gene Expression Taqman primers (Applied Biosystems) were used for PCR (Mm99999915_g1 for Gapdh; Mm00443147_m1 for Sema4d; Mm00555359_m1 for Plxnb1). Gapdh served as endogenous control. All primers were checked for equal efficiency over a range of target gene concentrations. Each sample was amplified in duplicate. PCR reaction mixture was run in Applied Biosystems Prism 7300 Sequence Detection System instrument utilizing universal thermal cycling parameters. Data analysis was done using relative quantification (ΔΔCt) or the relative standard curve method. As per the manufacturer’s recommendation, any cycle threshold (Ct) values obtained below 33 were considered undetectable for that particular target gene.

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.
