all breast cancer molecular subtypes, triple-negative breast cancer (TNBC) presents the poorest prognosis due to the lack of effective therapeutic options. TNBC, characterized by tumors that do not express estrogen receptor (ER), progesterone receptor (PR), or HER-2 genes, represents approximately 10%– 20% of invasive breast cancers and has been associated with African-American race, socioecono...

Familial breast and ovarian cancer prevalence was assessed among 1150 women of Mexican descent enrolled in a case-only, binational breast cancer study. Logistic regression was conducted to compare odds of triple negative breast cancer (TNBC) to non-TNBC according to family history of breast and breast or ovarian cancer among 914 of these women. Prevalence of breast cancer family history in a fi...

Triple-negative breast cancer (TNBC) is an aggressive disease with outcomes inferior to those of other breast cancer subtypes. No targeted therapies are currently approved for TNBC, and newer treatment approaches are critically needed. It is increasingly recognized that TNBC is a heterogeneous disease, and the role of androgen signaling in a subset of TNBC is emerging. Although the degree of an...

Triple-Negative Breast Cancer (TNBC) has poor prognosis and no approved targeted therapy. We previously showed that the enzyme fatty acid synthase (FASN) was largely expressed in a small TNBC patients' cohort and its inhibition synergized with cetuximab in TNBC preclinical mouse models. Here, we evaluated FASN and EGFR expression in a cohort of TNBC patients and we study their prognostic role a...

BACKGROUND No proven targeted therapy is currently available for the treatment of triple-negative breast cancer (TNBC). Epidermal growth factor receptor (EGFR) is frequently overexpressed in TNBC. We studied the activity of EGFR antagonists alone, and in combination with chemotherapy, in TNBC cell lines. MATERIALS AND METHODS EGFR and phosphorylated EGFR were measured by enzyme-linked immunos...

Triple-negative breast cancer (TNBC) is a subtype of breast cancer with a poor prognosis, accounting for approximately 12-24% of breast cancer cases. Accumulating evidence has indicated that there is no effective targeted therapy available for TNBC. Dipalmitoylphosphatidic acid (DPPA) is a bioactive phospholipid. However, the function of DPPA in the growth of TNBC has not yet been studied. In t...

PURPOSE Triple-negative breast cancer (TNBC) is a highly heterogeneous disease and has the worst outcome among all subtypes of breast cancers. Although PARP inhibitors represent a promising treatment in TNBC with BRCA1/BRCA2 mutations, there is great interest in identifying drug combinations that can extend the use of PARP inhibitors to a majority of TNBC patients with wild-type BRCA1/BRCA2 Her...

introduction: breast cancers are divided into at least 4 sub types on the basis of gene expression profiles and expression of receptors as measured by ihc (immunohistochemical). triple negative breast cancer (tnbc) is more chemosensitive yet, it is much harder to detect than other sub types. at present lack of highly effective therapeutic targets for tnbc, leaves standard chemotherapy, as the o...

Triple negative breast cancer (TNBC): challenges and solutions via the immune cells TNBC is one of the most complicated types of breast cancer to treat. It is generally diagnosed based on the absence of three receptors: estrogen, progesterone, and human epidermal growth factor receptor 2 (HER2) and is thus defined as a triple negative. TNBC is often more aggressive with lower survival rates...

BACKGROUND AHNAK, also known as desmoyokin, is a giant protein with the molecular size of approximately 700 kDa and exerts diverse functions in different types of cancer. RESULTS In the present study, we demonstrated that AHNAK mRNA levels were down-regulated in 7 out of 8 human breast cancer cell lines, especially in triple - negative breast cancer (TNBC) cell lines. Moreover, in patients wi...
