EFNA3 and lung cancer: Conversely, LINC01270 exhibits competitive endogenous (ce)RNA functions, as seen in its ability to sponge miRNA (miR)-326 to modulate the mRNA levels of LA-related protein 1 (LARP1) and Ephrin A3 (EFNA3), thus exacerbating lung cancer and gastric cancer progression, respectively [12,13].
