lncRNAs represent a large class of non-protein coding RNA molecules longer than 200 nucleotides. They can regulate gene expression through RNA-RNA interactions, however, which is one of the least studied aspects of lncRNA biology. CD Genomics provides sample-to-data RNA-seq, ChIRP-seq and ChIRP-MS services for identifying RNA targets of lncRNAs and determining the functions and action mechanisms of lncRNAs.
Long non-coding RNAs (lncRNAs) play many vital roles in multiple biological processes, but we have little knowledge about the function of the majority of lncRNAs. Every lncRNA mechanism involves lncRNA-RNA interaction and/or lncRNA-protein interaction. So one approach for modeling lncRNA mechanisms is to identify their interaction target. Recent studies have found that lncRNA-mRNA interactions can regulate biological processes, demonstrating that lncRNA-RNA interaction prediction is helpful for estimating the function of a lncRNA. Besides, the interaction of microRNA (miRNA) and lncRNA has been identified to be important for gene regulations. However, the number of known lncRNA-miRNA interactions is still very limited. Several experimental protocols, databases, web servers and computational tools have been developed for prediction of lncRNA functions based on lncRNA-mRNA interactions or in silico screening.
CD Genomics has strong expertise and rich experience in comprehensively predicting lncRNA-RNA interactions, including lncRNA-mRNA interactions, lncRNA-miRNA interactions and integrated analysis of mRNA-lncRNA-miRNA (MLMI) network. We provide whole transcriptome sequencing, ChIRP-MS and ChIRP-seq to comprehensively identify potential lncRNA-RNA interactions. ChIRP (Chromatin isolation by RNA purification) experiments can capture lncRNA-binding chromatin and transcripts, which can be identified by next-generation sequencing (NGS) or mass spectrometry (MS) in a high throughput and accurate manner. lncRNA-RNA interaction prediction can provide a detailed lncRNA-RNA interaction network and reveal lncRNA function.
