LINC01567 can regulate the proliferation of colon cancer stem cells (CSCs) through sponging miR-9, resulting in the modulation of Cyclin D2 (CCND2) and the regulation of aquaporin 3 (AQP3), which can be regulated by the CREB molecule in the cAMP–PKA pathway [51]. The gene discussed is CCND2; the disease is malignant colon neoplasm.
