RAB27A and pancreatic neoplasm: The protein Rab27a plays a crucial role in transporting lysosomes from the microtubule-organizing center (MTOC) to the plasma membrane, and enhanced Rab27a expression is closely associated with pancreatic cancer; furthermore, Rab27a-expressing hepatocellular carcinoma patients have poor survival, and invasive/metastatic potential of human breast cancer cells directly correlates with Rab27a expression [43, 44, 45, 46].Rab6 is located within the Golgi apparatus and it regulates protein trafficking; Rab6-mediated lung cancer growth is promoted by miR-5100 [47, 48].
