HNRNPK and gastric cancer: For instance, circFAM73A facilitates the cancer stem cell-like properties of GC via regulating the miR-490-3p/HMGA2 axis and β-catenin stabilization mediated by HNRNPK [7]; circLMO7 sponges miR-30a-3p to propel GC progression through the WNT2/β-catenin pathway [8]; and circFGD4 has been found to attenuate GC cell progression through regulation of the miR-532-3p/APC axis [9].
