The PIK3CA gene is mutated with high frequency in human breast cancers
Cancer biology & therapy, 2004•Taylor & Francis
The phosphatidylinositol 3-kinases (PI3Ks) are known regulators of cellular growth and
proliferation. It has recently been reported that somatic mutations within the PI3K subunit
p110?(PIK3CA) are present in human colorectal and other cancers. Here we show that
thirteen of fifty-three breast cancers (25%) contain somatic mutations in PIK3CA, with the
majority of mutations located in the kinase domain. These results demonstrate that PIK3CA
is the most mutated oncogene in breast cancer and support a role for PIK3CA in epithelial …
