The members of the network (interactome) that controls cancer needs to be known. This network consists of proteins and non-coding, single-stranded RNAs, such as microRNAs (miRNAs), long non-coding RNAs (lncRNAs), circular RNAs (circRNAs), and transfer RNAs (tRNAs). miRNAs are 21-23 nucleotides-long, and degrade messenger RNAs (mRNAs) and lncRNAs. lncRNAs are longer than 200 nucleotides, and sponge (sequester) miRNAs.
