Annotated lncRNA expression values do not differ significantly after storage for 1 year at − 80 °C. lncRNA expression levels were measured using a total RNA immediately isolated from PAXgene tubes at baseline or RNA isolated after PAXgene tubes were stored at − 80 °C for one year, b total RNA isolated at baseline compared to the same RNA stored at − 80 °C for one year, or c cDNA immediately prepared using baseline total RNA or the same cDNA sample stored for one year at − 80 °C. Student’s t-test with Welch’s correction was used to determine statistical significance. Bars represent mean Log2(ΔΔCt) with SD for n = 5 PAXgene tubes with pooled blood, RNA samples or cDNA samples in each experimental group
