PIK3CA mutations in ovarian cancer.
To the Editor: In the April 15 issue of Clinical Cancer Research, Levine et al. (1) reported the frequent occurrence of somatic mutations in the phosphatidylinositol 3-kinase p110a catalytic subunit gene PIK3CA in breast and ovarian cancer. While their study broadly supports the conclusions of our previous report in these cancer types (2), there are some important differences. We observed a hig...
متن کاملOncogenic mutations of PIK3CA in human cancers.
Phosphatidylinositol 3-kinases (PI3Ks) are important regulators of signaling pathways. To determine whether PI3Ks are genetically altered in human cancers, we recently analyzed the sequences of the PI3K gene family and discovered that one member, the PIK3CA gene encoding the p110alpha catalytic subunit, was frequently mutated in cancers of the colon, breast, brain and lung. The majority of muta...
متن کاملFrequent mutation of the PIK3CA gene in ovarian and breast cancers.
PURPOSE Activation of the phosphatidylinositol 3-kinase (PI3K)-AKT pathway, resulting in increased cell proliferation, survival, and motility, is believed to play an oncogenic role in many cancer types. The PIK3CA gene encodes the p110alpha catalytic subunit of PI3K, and is amplified in some ovarian cancers, whereas the AKT2 gene is amplified in some ovarian, breast, and pancreatic cancers. Rec...
متن کاملA Review of Driver Genetic Alterations in Thyroid Cancers
Thyroid cancer is a frequent endocrine related malignancy with continuous increasing incidence. There has been moving development in understanding its molecular pathogenesis recently mainly through the explanation of the original role of several key signaling pathways and related molecular distributors. Central to these mechanisms are the genetic and epigenetic alterations in these pathways, su...
متن کاملPIK3CA mutations and copy number gains in human lung cancers.
We investigated the frequency and function of mutations and increased copy number of the PIK3CA gene in lung cancers. PIK3CA mutations are one of the most common gene changes present in human cancers. We analyzed the mutational status of exons 9 and 20 and gene copy number of PIK3CA using 86 non-small cell lung cancer (NSCLC) cell lines, 43 small cell lung cancer (SCLC) cell lines, 3 extrapulmo...
