Over 3000 studies have reported that lncRNAs function as sponges to interact with miRNAs; for example, lncRNA ZFAS1 can sponge miR-150-5p to upregulate VEGFA expression to contribute to the progression of colorectal cancer [37], yet other regulatory mechanisms of lncRNAs are few reported. The gene discussed is VEGFA; the disease is colorectal cancer.
