ATG14 and neoplasm: Moving forward, research efforts ought to prioritise several critical areas: first, to systematically analyse the dual biological functions of autophagy at different stages of tumour evolution (primary foci formation, metastatic colonisation and therapeutic resistance), and second, to elucidate the spatial and temporal regulation of novel autophagy regulatory elements (e.g., ATG9 vesicle transport system, ATG14‐mediated PI3K complex assembly) by O‐GlcNAcylation.
