For FFPE tissues, tumor-rich areas (>30-50% of neoplastic cells) were microdissected from three to six 4-μm unstained histologic sections under stereomicroscopic visualization with an Olympus SZ61 microscope (Olympus, Hamburg, Germany). Total nucleic acids were isolated from each target with the DNeasy Blood and Tissue kit on the automated QIAcube (Qiagen, Valencia, CA) instrument according to the manufacturer's instructions. Extracted DNA and RNA were quantitated on the Qubit 2.0 Fluorometer using the dsDNA HS Assay Kit and the RNA HS Assay Kit (Invitrogen, Carlsbad, CA).

Larvae were raised on NutriFly media and staged at 42 hr after the L2/L3 molt. 50 individual ring glands were collected per replicate, dissolved in Trizol, and stored at -80° for later qPCR analysis. RNA was extracted using Qiagen RNeasy extraction kit (74106) and concentrations were measured via the RNA HS assay kit (Invitrogen Q32852) in a Qubit 2.0 (Invitrogen Q10210). Extracted samples were reverse- transcribed via the ABI High capacity cDNA synthesis kit (ThermoFisher 4368814). Synthesized cDNAs were used for qPCR (QuantStudio 6 Flex, Applied Biosystems) using the Luna Universal qPCR master mix (NEB M3003S). Samples were normalized to rp49 by calculating fold changes via the ΔΔCT method.

Cytogenetic analysis was performed following standard procedure and G-banded karyotypes (7 ). FISH experiments on metaphase chromosomes were performed as previously described (8 (link)) using the following probes: Vysis CEP 1 (D1Z5, SpectrumOrange Probe, Abbott) for alphoid sequences of chromosome 1 and Vysis CEP 7 (D7Z1, SpectrumGreen Probe, Abbott) for chromosome 7 α-sat DNA (Fig. 1b). Analyses were carried out using a fluorescence microscope Olympus BX61 equipped with a highly sensitive camera JAI and driven by CytoVision 4.5.4 software. At least 7 abnormal metaphases were analyzed in each experiment.
Nucleic acids were extracted from unsorted bone marrow cells of patients using All Prep DNA/RNA Mini Kit (Qiagen), quantified with Qubit fluorimeter using Quant-i-T dsDNA HS Assay Kit and RNA HS Assay Kit (Invitrogen) respectively and samples quality was evaluated using Tapestation visualization (Agilent 2100 Bioanalyzer). Mutational diagnostic screening of 14 MDS-related genes was performed using DHPLC (Wavemaker software, Wave System, MD Transgenomic Inc., USA) and Sanger sequencing (3500 Genetic Analyzer, Applied Biosystems) (Table 1; Supplementary Table 1).

RNA Isolation and RNA-Seq Library Preparation

Check if the same lab product or an alternative is used in the 5 most similar protocols
Total RNA was isolated using the RNeasy Plant Mini Kit (Qiagen, USA) after grinding plant material (100–150 mg) in liquid nitrogen. The amount of RNA was determined using a Qubit fluorometer (Invitrogen, USA) using the Qubit RNA HS Assay Kit. To create barcoded RNA-Seq libraries, the NEBNext® Ultra II RNA Library Prep Kit for Illumina® (New England BioLabs, USA) was used according to the manufacturer’s protocol. Sequencing of the obtained libraries was performed on a high-performance sequencer NovaSeq 6000 (Illumina, USA) using the NovaSeq 6000 S1 Reagent Kit v1.5 (300 cycles).

The RNA from ventral roots were obtained using TRI Reagent (Sigma-Aldrich), following the recommendations of the manufacturer. Quality and quantity of RNA was evaluated using spectrophotometry (Nanodrop 1000, Thermo Scientific) and fluorimetry (Qubit 2.0 and RNA HS Assay kit, Invitrogen, ThermoFisher Scientific). To be in comparable concentration as the RNA extracted from axons, each ventral root RNA was diluted down to 500 pg and then reisolated with the RNAqueous-Micro Total RNA Isolation Kit, following the procedure detailed above.

For each plant species, four infected samples and one mock inoculated sample were randomly selected out of ten replicates for total RNA extraction and downstream analysis using the different quantification techniques. For N. tabacum, RNA was extracted from 100 μl of homogenised leaf tissue using the RNeasy Plant Mini Kit (Qiagen), following the manufacturer's protocol (with on-column DNAse digestion). For C. quinoa, RNA was extracted from 200 μl of homogenised leaf tissue using the Direct-zol RNA miniprep kit (Zymo), following the manufacturer's protocol. For N. benthamiana, RNA was extracted from 100 μl or 200 μl of homogenised leaf tissue using the Direct-zol RNA miniprep kit (Zymo), following the manufacturer's protocol. For all samples, RNA was eluted in 40 μl RNase free water, and yield and purity were determined using the Nanodrop spectrophotometer and Qubit3 fluorometer (RNA HS Assay kit, Invitrogen). After extraction, multiple aliquots of RNA were stored at −80 °C.

To investigate how treatment with the combination of CQ and 5-FU changes tumor cell gene expression, we performed a transcription analysis of these cells. Total RNA was extracted using a QIAGEN RNeasy Plus Micro Kit. RNA was quantified using an RNA HS Assay Kit (Invitrogen) and a QBIT® system. The quality of RNA was analyzed using an Agilent RNA 6000 chip in a Bioanalyzer 2100 system. Only samples with an RNA integrity number higher than 8.0 (optimal quality) were processed.
All indications and steps of the Sure Select Strand-Specific RNA Library Preparation Kit were followed, and the dsDNA libraries of each treatment group with the adapters and index were analyzed on the Illumina Miseq platform. After obtaining the data, the reads were assembled based on the sequences of each transcript of interest using the CLC Genomics Workbench program. The effect of the treatments on gene expression was evaluated by comparing the fold change in RNA expression of the samples with that of the untreated control.

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.
