The experimental design and cell harvesting for RNAseq analysis were performed as described for the RT-qPCR analysis. Three biological replicates from each time point of control and induced cultures were ground to a powder in liquid N2. Total RNA was extracted using ReliaPrep RNA Miniprep System (Promega) followed by DNAse treatment (DNAse RQ1, Promega), according to manufacturer’s instructions. RNA integrity/quality and concentration were assessed using Agilent Bioanalyzer RNA 6000 pico kit in a Bioanalyzer 2100 (Agilent Technologies) and Qubit 2.0 (Thermo Fisher Scientific), respectively. RIN (RNA integrity number) scores of above 7 were used. Poly-A mRNA isolation and cDNA libraries construction were carried out using NEBNext Poly(A) mRNA Magnetic Isolation Module (New England Biolabs) and NEBNext Ultra II Directional RNA Library Prep kit for Illumina (New England Biolabs), respectively, according to manufacturer’s protocols and using unique barcode for each sample.

Right lung tissues were lysed for RNA extraction using the ReliaPrep RNA Miniprep System (Promega Corporation, Madison, WI) as per the manufacturer's protocol. The total RNA concentration and purity was measured by spectrophotometry using a Nanodrop ND‐1000 system (Thermo Fisher Scientific, Waltham, MA). Approximate A260/A230 and A260/A280 ratios of two were considered ideal for RNA purity.63 First‐strand cDNA was synthesized from 1 μg purified RNA using a high‐capacity cDNA reverse transcription kit (Thermo Fisher Scientific). The relative levels of mRNA were measured by SYBR Green detection (Promega) in a PCR Mastercycler Ep Realplex system (Eppendorf, Hamburg, Germany). All samples were measured in triplicate. The relative TGF‐β1 transcript level was calculated as the ratio of the levels of the target gene (i.e., TGF‐β1) over the control gene (ie, acidic ribosomal phosphoprotein P0, 36B4). The primer sequences used in this study were: forward CAACCCAGCTCTGGAGAAAC and reverse GTTCTGAGCTGGCACAGTGA for 36B4; forward CTAATGGTGGACCGCAACAAC and reverse GACAGCCACTCAGGCGTATC for TGF‐β1.

RNA-seq was performed in triplicates per condition, including three independently derived clonal lines per genetic knock-out, and two RGd2 lines as wild-type controls. Exception is RGd2-N16h samples for which only 2 replicates were sequenced, as one was lost during library preparation. RGd2-2 is a clonal line derived from the parental RGd2 line (RGd2-1). Total RNA was extracted with ReliaPrep RNA Miniprep System (Promega) and was processed with Ribo-Zero capture probes (Illumina). Libraries were produced using NEXTflex Rapid Directional qRNA-Seq Kit (Bioo Scientific). Libraries were sequenced in the Illumina platform in paired-end mode.

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.
