The authors uncover the cellular and molecular mechanisms, as well as the gene network regulated by Sox9 during the early steps of skin tumor initiation and demonstrates that Sox9 controls the long term maintenance and expansion of oncogene expressing cells by promoting self - renewing division and inhibiting differentiation.

In humans, cancer develops when genes that suppress cancer, known as tumor suppressors, are lost and when mutations or genes that promote cancer, known as oncogenes, are gained or activated.
