Also, octamer‐binding transcription factor 4 (OCT4), an important regulator gene involved in the maintenance of self‐renewal properties in stem cells, was also found to bind to miR‐125b‐1 to increase miR‐125b levels, thereby suppressing apoptosis and promoting tumourigenesis in cervical cancer.64 The gene discussed is POU5F1; the disease is cervical carcinoma.
