MTOR and lung carcinoma: LncRNAs mainly regulate the chemosensitivity of lung cancer cells through the following mechanisms: 1) MAPK/ERK signaling pathway, 2) PI3K/AKT/mTOR and NF‐κB signaling pathway, 3) mitochondrial pathway, 4) STAT3 signaling pathway, 5) affecting cancer cell stemness by regulating the Wnt/β‐catenin signaling pathway, 6) activating or inactivating Beclin‐1 through crosstalk between apoptosis and autophagy, 7) epithelial to mesenchymal transition (EMT), 8) autophagy, and 9) multidrug resistance (MDR) (Figure 1).
