In lung cancer cells, IFN‐γ triggered annexin A2 (ANXA2) exocytosis via a Rab11‐Rab8a and Rab27a mediated secretory autophagy pathway including the fusion of AP and MVB to form amphisome followed by migration to the plasmid membrane and exocytosis.18 This evidence concerns the gene RAB27A and lung carcinoma.
