SOX2 is one of the members of the SOX transcription factor family, which is believed to be an important transcription factor that plays a role in embryonic development, maintenance of stem cells, cancer progression, and resistance to cancer treatment. There is increasing evidence suggesting that SOX2 is crucial for the initiation, progression, invasion, metastasis, and treatment resistance of prostate cancer, therefore understanding the mechanism of SOX2 in prostate cancer can provide better targets for the treatment of prostate cancer. This article reviews the structural domains, normal physiological functions, and role in prostate cancer progression of SOX2, providing potential targets for prostate cancer treatment.
