Molecular pathways: PI3K pathway targets in triple-negative breast cancers.
The triple-negative breast cancer (TNBC) subtype, defined clinically by the lack of estrogen, progesterone, and Her2 receptor expression, accounts for 10% to 15% of annual breast cancer diagnoses. Currently, limited therapeutic options have shown clinical benefit beyond cytotoxic chemotherapy. Defining this clinical cohort and identifying subtype-specific molecular targets remain critical for n...

متن کاملMolecular stratification of triple-negative breast cancers.
Research focused on the analysis and classification of breast tumors, primarily using DNA microarrays and patterns of gene expression, has resulted in distinct tumor subtypes. Although no knowledge of patient survival or outcomes was used to derive these gene descriptions, these different classes based upon patterns of gene expression have important prognostic implications. Predictive markers i...
متن کاملTargeting mTOR pathway inhibits tumor growth in different molecular subtypes of triple-negative breast cancers
Triple-negative breast cancers (TNBC) are characterized by frequent alterations in the PI3K/AKT/mTOR signaling pathway. In this study, we analyzed PI3K pathway activation in 67 patient-derived xenografts (PDX) of breast cancer and investigated the anti-tumor activity of the mTOR inhibitor everolimus in 15 TNBC PDX with different expression and mutational status of PI3K pathway markers. Expressi...
متن کاملThe omics of triple-negative breast cancers.
BACKGROUND Triple-negative breast cancers (TNBC) do not represent a single disease subgroup and are often aggressive breast cancers with poor prognoses. Unlike estrogen/progesterone receptor and HER2 (human epidermal growth factor receptor 2) breast cancers, which are responsive to targeted treatments, there is no effective targeted therapy for TNBC, although approximately 50% of patients respo...
