Blood-cell mutations had opposite effects on breast tumors in mice

As mice aged, mutations in the Dnmt3a gene prevented breast cancer progression, while mutations in the Tet2 gene drove it.As mice aged, mutations in the Dnmt3a gene prevented breast cancer progression, while mutations in the Tet2 gene drove it.
