“…SRY‐box transcription factor 9 ( SOX9 ), as a member of SOX family, can keeps cells in undifferentiated state during development and is correlated with many signalling pathways such as NOTCH , transforming growth factor‐beta (TGF‐β)/Smad and Wnt/β‐catenin. 97 , 98 SOX9 has been reported to be implicated in regulating various cellular processes including proliferation, apoptosis, migration, invasion, chemoresistance, autophagy, angiogenesis, immune escape and metastasis by controlling the transcription of a multitude of genes. 99 , 100 Multiple lines of evidence support the suggestion that SOX9 is involved in the development of diverse types of malignancies such as bladder, brain, colon, cervical, gastric, endometrial, liver, and head and neck cancers.…”
