The mRNA fragmentation was performed using divalent cations and high temperature. Priming was performed using Random Primers. First strand cDNA and the second-strand cDNA were synthesized. The purified double-stranded cDNA was then treated to repair both ends and add a dA-tailing in one reaction, followed by a T-A ligation to add adaptors to both ends. Size selection of Adaptor-ligated DNA was then performed using DNA Clean Beads. Each sample was then amplified by PCR using P5 and P7 primers and the PCR products were validated.","Sequencing - Then libraries with different indexs were multiplexed and loaded on an Illumina HiSeq/ Illumina Novaseq/ MGI2000 instrument for sequencing using a 2x150 paired-end (PE) configuration according to manufacturer’s instructions.","Sample Collection - Tissue specimens were collected from surgically resected tumor samples of patients, snap-frozen at -80°C, and transferred in liquid nitrogen. This study was approved by the Ethics Committee.","Nucleic Acid Extraction - Total RNA was extracted from the samples using the [Insert Kit Name, e.g., TRIzol reagent / Qiagen RNeasy Mini Kit] according to the manufacturer's instructions. The concentration and purity of the RNA were determined by measuring the absorbance at 260 nm and 280 nm using a NanoDrop spectrophotometer (A260/A280 ratio). RNA integrity was assessed by agarose gel electrophoresis to verify the presence of intact 18S and 28S ribosomal RNA bands."],"figure_sub":["Organization","MINSEQE Score","Assays and Data","MAGE-TAB Files"],"pubmed_authors":["yi wei"],"additional_accession":[]},"is_claimable":false,"name":"Construction and Clinical Validation of a Colorectal Cancer OPISV Prognostic Model Integrating EPHB2 and ZNF346: Potential Regulatory Role of the Axon Guidance Pathway","description":"RNA-seq data were derived from tumor tissue samples of four colorectal cancer patients and quantified using STAR.
