Figure Lengend Snippet: Comparison of human rRNA removal specificity and efficiency between the RTR2D procedure and NEBNext® rRNA Depletion kit. Human total RNA (1.0 µg) was subjected to the RTR2D (R2D) (with the pooled rRNA probes) or the NEBNext® rRNA Depletion (NEB) protocol. The rRNA-depleted products were subjected to the Bioanalyzer. Representative gel image ( a ) and electropherograms ( b ) are shown. “Input” and “No probes (NP)” groups were used as controls. ( B ) TqPCR analysis of the residual rRNA species ( a ) and removal efficiency ( b ). “**” p < 0.001, compared with that of the NP group or the Input group. ( C ) Effect of rRNA removal protocols on the expression of housekeeping genes GAPDH and β-ACTIN ( a ) and genes/lncRNA with different abundances, c-MYC , TP53 and lncRNA HOTAIR ( b ). All qPCR reactions were done in triplicate.

Article Snippet: Commercially available pull-out kits include Ribo-Zero (Illumina, USA) and RiboMinus (Thermo Fisher, USA), while the RNase H-based rRNA degradation of oligo-DNA:RNA hybrids includes RiboErase (Kapa Biosystems, USA) and NEBNext rRNA Depletion (New England Biolabs, NEB), which depletes both cytoplasmic (5S rRNA, 5.8S rRNA, 18S rRNA and 28S rRNA) and mitochondrial ribosomal RNA (12S rRNA and 16S rRNA) from human, mouse and rat total RNA preparations.

Figure Lengend Snippet: Transcriptomic comparison of the RNA-seq libraries prepared with the RTR2D and the NEBNext rRNA Depletion protocols. Human total RNA (1.0 µg) was subjected to the rRNA removal process by using the RTR2D procedure (R2D) and the NEBNext rRNA Depletion kit (NEB). The rRNA-depleted samples were used for RNA-seq library preparations using the Illumina protocol and subjected to NGS analysis (in replicate). ( A ) The average valid reads (RPKM) for the RTR2D ( a ) and the NEB kit ( b ) are depicted in various categories of transcripts. ( B ) Scatter plots and correlations of mRNA transcripts between the RTR2D and the NEB protocols in two different batches of preparations ( a & b ). ( C ) Scatter plots and correlations of lncRNA transcripts between the RTR2D and the NEB protocols in two different batches of preparations ( a & b ).

Figure Lengend Snippet: Nutlin3A-induced transcriptomic changes determined by RNA-seq analysis of the NGS libraries prepared with the RTR2D and the NEBNext rRNA Depletion protocols . Exponentially growing human osteosarcoma line SJSA1 cells were treated with 2 µM Nutlin3A or DMSO control for 24 h and subjected to total RNA isolation. Human total RNA (1.0 µg) was subjected to rRNA removal by using the RTR2D procedure (R2D) and the NEBNext rRNA Depletion kit (NEB). The rRNA-depleted samples were used for RNA-seq library preparations using the Illumina protocol and subjected to NGS analysis. ( A ) Scatter plots of mRNA transcripts affected by DMSO (Y-axis) and Nutlin3A (X-axis) identified in the RNA-seq libraries prepared with the NEB protocol ( a ) or the RTR2D protocol ( b ). Venn diagrams were generated by using more stringent criteria for the differentially expressed transcripts for up-regulated ( c ) (total relative reads > 54) and down-regulated transcripts ( d ) (total relative reads > 13). ( B ) Scatter plots of lncRNA transcripts affected by DMSO (Y-axis) and Nutlin3A (X-axis) identified in the RNA-seq libraries prepared with the NEB protocol ( a ) or the RTR2D protocol ( b ). Significant up and down-regulated transcripts were defined as log2FoldChange > 1 and < −1, respectively, with a false detection rate (FDR) < 0.001. Venn diagrams were generated by using more stringent criteria for the differentially expressed transcripts for up-regulated ( c ) (total relative reads > 540) and down-regulated transcripts ( d ) (total relative reads > 20).
