LncRNA NNT antisense RNA 1 (NNT‐AS1) and small nucleolar RNA host gene 12 (SNHG12) have been shown to upregulate the EMT‐related transcription factor Slug through the MAPK/ERK signaling pathway to promote EMT, making lung cancer cells resistant to chemotherapy.62, 63. Here, SNHG12 is linked to lung cancer.
