ncRNA functions in tumor progression
miRNAs regulate gene expression by inducing RNA cleavage or degradation or blocking RNA translation. lncRNAs function as molecular signals, decoys, guides, or scaffolds to mediate gene expression by interacting with DNAs, mRNAs, proteins, or other ncRNAs. circRNAs mediate gene expression by acting as miRNA sponges and protein scaffolds. Both of those ncRNAs play important roles in cancer progression, such as tumor transformation, growth, and angiogenesis.
