Agene known to be active in fetal cells is also expressed in aggressive forms of breast cancer, pointing to a possible explanation for cancer cells’ ability to regain the potential to evolve into other types and metastasize to different regions in the body. The findings were published last month (August 30) in Cancer Cell.
The gene in question, Sox10, controls several processes, including cell development and movement, as a transcription factor.
The researchers noticed that breast cancer cells from humans and mice with abundant Sox10 reverted to undifferentiated variants that turned invasive and freely migrated. In a mouse experiment, they observed that disrupting Sox10 function stopped cancer formation ...
