CAPNS1 and neoplasm: It has also been reported that miR-9-3p suppresses the epithelial-mesenchymal transition (EMT) in NPC cells by downregulating fibronectin 1 (FN1), β1 integrin (ITGB1), and α5 integrin (ITGAV) [39], while miR-124 suppresses tumor growth by targeting calpain small subunit 1 (CAPN4) and signal transducer and activator of transcription 3 (STAT3) [40, 41].
