For example, hsa_circ_0001020 serves as a potential biomarker for gastric cancer screening and prognosis;22 hsa_circ_0030998 promotes tumor proliferation and angiogenesis by sponging miR‐567 to regulate VEGFA in colorectal cancer;23 CircDIDO1 suppresses PRDX2 protein stability by encoding a novel DIDO1‐529aa protein and regulates PRDX2 protein stability to inhibit gastric cancer progression;24 Circular RNA circ β‐catenin aggravates the malignant phenotype of non‐small‐cell lung cancer via encoding a peptide,25 among other studies, confirming the broad biological functions of circRNAs. The gene discussed is VEGFA; the disease is neoplasm.
