LECs and BECs were first transfected in duplicates with eight ASOs independently (negative control A and B and three ASO per lncRNA target; Additionalfile1). Robinson MD, Oshlack A. 1a). To investigate the potential roles of lncRNAs in vascular biology, we performed antisense oligonucleotide (ASO) knockdowns of lncRNA candidates specifically expressed either in human lymphatic or blood vascular endothelial cells (LECs or BECs) followed by Cap Analysis of Gene Expression (CAGE-Seq). Additional GO enrichment analysis revealed that negative control B-specific DE genes in LECs were enriched for various biological processes (Fig. Thus, we pinpoint the essential need to accurately examine multiple negative control ASOs in order to select a proper control set with no to minimal effects on the transcriptome of the targeted cell types. and S.A. designed the project, performed the in silico analyses and wet-lab experiments, and wrote the manuscript.

While Mic10 is part of a large hetero-oligomeric complex, it has been proposed that the protein itself might form homo-oligomers in the IM (Harner et al., 2011).Mic10 has two highly conserved elongated GxxxG motifs in its two transmembrane domains (Figure First, we recommend including not only libraries from untreated cells but also lipofectamine-only treated cells to evaluate the potential effects of the transfection reagent on the cell of interest [31]. Andrew S. FastQC: a quality control tool for high throughput sequence data. 1 Approved Answer. Keuschnigg J, Karinen S, Auvinen K, Irjala H, Mpindi JP, Kallioniemi O, et al. Next, we investigated whether the effects of ASO transfection on the general transcriptome of LECs or BECs were consistent between the two negative control ASOs by comparing them to the untransfected reference CAGE-Seq samples (Additional file 2, refer to the original study [18] for further details). However, we also observed that referencing to either negative control A or B led to slight differences in the degree of the KD efficiencies in our CAGE-Seq data compared to qPCR results (Fig. a) None, they remain the same b) Besides that, we also suggest including alternative negative control ASOs such as mismatched sequences that abrogate the binding to the target sequence.
