Furthermore, CaO2-MNPs inhibited autophagy and induced apoptosis in TNBC cells. Our animal studies with an orthotopic mouse model showed that CaO2- MNPs in combination with doxorubicin exhibited a stronger tumor-suppressive effect on TNBC,

Researchers have discovered that there are many variations of triple-negative breast cancer, and about 15-20% of breast cancer diagnoses in the U.S. are triple negative. Early-phase trials targeting the T-cell inhibitory molecule programmed cell death ligand 1 (PD-L1) have shown clinical efficacy in cancer. This study was undertaken to determine whether PD-L1 is overexpressed in triple-negative breast cancer (TNBC) and to investigate the loss of PTEN as a mechanism of PD-L1 regulation.

Jun 17, 2017 · Triple-negative breast cancer (TNBC) should be regarded as a working category that, although useful for current clinical decisions, might have only limited value as a defined biological category for future targeted therapy approaches, because of its triple-negative definition. Background: The significance of androgen receptor (AR) expression in triple-negative breast cancer (TNBC) is unclear, and published studies so far have been inconclusive. Methods: A tissue microarray was constructed using tissue obtained from 119 patients with primary TNBC and stained for AR expression. Triple-negative breast cancer (TNBC) is a highly diverse group of cancers, and subtyping is necessary to better identify molecular-based therapies. In this study, we analyzed gene expression (GE) profiles from 21 breast cancer data sets and identified 587 TNBC cases.

types are not synonymous [3, 12]. To gain more insight into the heterogeneity of TNBC, researchers from the Netherlands. †Co-first authors. ‡Co-last authors.

Subsequently, in the regulation of p53 protein, we also found that reducing LINP1 level could restore the sensitivity of 231-RO to Olaparib.

However, the anticancer mechanism of RSV on triple negative breast cancer (TNBC) remains unclear.

Background Triple-negative breast cancer (TNBC) is the most aggressive subtype of breast cancer that lacks expression of estrogen receptor (ER) and progesterone receptor (PR) and the human epidermal growth factor receptor 2 (HER2) gene. Chemotherapy remains the standard of care for TNBC treatment, but considerable patients are very resistant to chemotherapy. Mutations or aberrant upregulation

Unfortunately, up to 70% of patients with TNBC develop resistance to treatment. A known contributor to chemoresistance is dysfunctional mitochondrial apoptosis signaling.

Identification of human triple-negative breast cancer subtypes and preclinical models for selection of targeted therapies. J Clin Invest . 2011;121(7):2750-2767. Pathologic complete response (pCR) following neoadjuvant therapy has been associated with improved event-free survival (EFS) and overall survival (OS) in early-stage breast cancer. The magnitude of this association varies by breast cancer subtype, yet further research focusing on subtype-specific populations is limited.

Our animal studies with an orthotopic mouse model showed that CaO2- MNPs in combination with doxorubicin exhibited a stronger tumor-suppressive effect on TNBC, Background Triple-negative breast cancer (TNBC) treatment is currently restricted to chemotherapy. Hence, tumor-specific molecular targets and/or alternative therapeutic strategies for TNBC are urgently needed. Immunotherapy is emerging as an exciting treatment option for TNBC patients.

4 Burstein et al showed that basal-like immune-suppressed subtypes of TNBC have downregulation of B cell, T cell and natural killer in both cytokines and immune pathways, which results in worse prognosis for these subtypes. 6 Mostly, all cell lines harboring mutations in BRCA1 and BRCA2 have correlation with the Background Triple-negative breast cancer (TNBC) is the most aggressive subtype of breast cancer that lacks expression of estrogen receptor (ER) and progesterone receptor (PR) and the human epidermal growth factor receptor 2 (HER2) gene. Chemotherapy remains the standard of care for TNBC treatment, but considerable patients are very resistant to chemotherapy. Mutations or aberrant upregulation TNBC is characterized by chromosomal instability resulting from homologous recombination repair (HRR) pathway deficiency (HRD) (36). The common causes of HRD include germline BRCA1/2 mutations, BRCA gene promoter methylation, and any genetic mutations of the HRR pathway (37).

They concluded that eight lncRNAs and one mRNA could act as prognostic factors in TNBC, using survival analysis and receiver operating characteristic (ROC) curve creation in the network. 42 Additionally, they found that lncRNA OSTN‐AS1 was primarily related to immunologic function, including immune cell infiltration and immune‐related markers co‐expression. 42 Song et al also constructed

So far, the clinical management of TNBC is challenging because of its heterogeneity and paucity of specific targeted therapy. Triple negative breast cancer (TNBC) is a complex and aggressive subtype of breast cancer which lacks oestrogen receptors, progesterone receptors and HER2 amplification, thereby making it difficult to target therapeutically. Triple-negative breast cancer (TNBC) is associated with high histologic grade, aggressive phenotype, and poor prognosis. Even though triple-negative breast cancer patients benefit from standard chemotherapy, they still face high recurrence rates and are more likely to develop resistance to chemotherapeutic drugs. Background: Triple-negative breast cancers (TNBC) are defined as not having amplification of the estrogen receptor, progesterone receptor, or epidermal growth factor receptor 2. Recovery of patients is, currently, severely limited after diagnosis of metastatic TNBC, with fewer than 30 % of patients surviving more than 5 years.
