EMT is a key mechanism of tumour metastasis, regulated by different signalling pathways and various growth factors.34 TGFβ was the key EMT inducer and regulated various cellular responses.35, 36 In this study, SNAI3‐AS1 regulated EMT by targeting the TGFβ signalling pathway in two non‐mutually exclusive ways. Here, SNAI3 is linked to neoplasm.
