However, based on the current experimental settings, we cannot completely exclude that some of these changes are also due to impacts intrinsically connected to both negative control ASOs. Specificity of RNAi, LNA and CRISPRi as loss-of-function methods in transcriptional analysis. Since studies involving ASOs in characterizing lncRNA function are increasing [28, 29], future investigators must be aware of the potential challenges encountered when comparing their ASO knockdown data to negative control ASOs.

FastQC: a quality control tool for high throughput sequence data. Discovery and annotation of long noncoding RNAs. Genetic analysis of protein stability and function. During the last decades, the FANTOM (Functional Annotation of the Mammalian Genome) consortium made striking contributions to the discovery and characterization of the lncRNAs by demonstrating, through Cap Analysis of Gene Expression (CAGE-Seq), that the human genome is constitutively transcribed, producing various sense and antisense transcripts [3]. In the nucleus, lncRNA transcripts can act either locally (in cis) or on different chromosomes (in trans), primarily as a scaffold for various functional protein complexes involved in transcriptional regulation, chromatin remodeling, or RNA processing [11,12,13,14]. Esteller M. Non-coding RNAs in human disease. Nucleic Acids Res. 2021;49(4):182839. However, there is no sharp distinction between these two concepts. 2007;109(11):477785. E.S.

Moreover, some lncRNA genes do not function through their transcribed RNA molecules but rather through their simple act of transcription [11,12,13,14]. Plasticity of Blood- and Lymphatic Endothelial Cells and Marker Identification. 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). 2017;543(7644):199204.
