Another faulty gene linked to breast cancer
Yet another gene has been found that appears to be associated with the development of breast cancer.
Tip60 is a so-called tumor suppressor gene - it helps to hold the growth of cells in check. Low Tip60 activity appears to be particularly associated with aggressive tumors.
When we are born we inherit a copy of the gene from our mother and our father. Typically with tumor suppressor genes, both copies must be faulty for the function to be lost. However the Tip60 gene stops working if only one copy is faulty. This is unusual.
There’s still a long way to go in understanding the role Tip 60 plays in the development of breast cancer but this discovery all adds to the bigger picture of how breast cancer develops.
