In this context, most of the noncoding genome is transcribed into long noncoding RNAs (lncRNAs). 2. g. (2020) ncRNA-eQTL: a database to systematically evaluate the effects of SNPs on non-coding RNA expression across cancer types. The RNA polymerase II core. lncRNA discovery is still at an early stage and only a small proportion of lncRNAs have so far been investigated. 2019;19:459. Noncoding RNA (ncRNA) is defined as RNA that is not translated into protein, and there are many types of ncRNA with a variety of biological functions (1) (Figure 1, Table 1). mansoni atlas of single-cells comprising expression data of protein-coding and lncRNA genes. LncRNAs in plants were annotated using strict standards for assurance of high confidence. While many studies have exploited public resources such as RNA sequencing (RNA-Seq) data in The Cancer Genome Atlas to study lncRNAs in cancer, it is crucial to choose the optimal method for accurate expression.
