SPRY4 and cancer: The lncRNAs were selected according their potential to promote or influence the following processes: CRC progression in general (TUG1, GAS5 and MALAT1) [10,11,14,15], cell proliferation (SPRY4-IT1, GAS5 and CCAT-1) [10,12,16], cell migration (ANRIL) [17], apoptosis (PCAT1) [8], regulation of tumour suppressors such as p53 (linc-ROR) [18] and inhibition of epithelial-mesenchymal transition (EMT) in other cancer types (MIR155HG) [19] (references, full names and functions for each selected lncRNA are stated in Table S1).
