Tamoxifen is widely used for the treatment of hormonally responsive breast cancers. However, some resistant breast cancers develop a growth proliferative response to this drug, as evidenced by tumor regression upon its withdrawal. To elucidate the molecular mediators of this paradox, tissue samples from a patient with tamoxifen-stimulated breast cancer were analyzed. These studies revealed that...
ErbB3 is a critical activator of phosphoinositide 3-kinase (PI3K) signaling in epidermal growth factor receptor (EGFR; ErbB1), ErbB2 [human epidermal growth factor receptor 2 (HER2)], and [hepatocyte growth factor receptor (MET)] addicted cancers, and reactivation of ErbB3 is a prominent method for cancers to become resistant to ErbB inhibitors. In this study, we evaluated the in vivo efficacy ...
HMGB1/RAGE is identified as a ligand-receptor pair that plays an important role in tumorogenesis. HMGB1 and RAGE levels are higher most human tumors their overexpression associated with tumor progression. The causes of breast cancer still poorly understood. One reason might be the existence subtypes within various cellular mechanisms hormone-dependent hormone -independent malignant processes. W...
PURPOSE About 50% of prostate cancers have TMPRSS2-ERG fusions with concurrent ERG overexpression. The aim of this study was to determine whether clinical differences exist between ERG-positive and ERG-negative cancers in surgically treated patients not exposed to antihormonal therapy. A secondary aim was to search for differences between these tumor classes. EXPERIMENTAL DESIGN A tissue micr...
Context: Breast cancer represents a significant public health problem concern the world, given its frequency (20% to 25% of female cancers) and diagnosis clinical stage with particular locally advanced cancers inflammatory forms. Objectives: To describe socio-demographic, histological characteristics breast at University Clinics Kinshasa. Methods: A descriptive retrospective study was completed...
In several human malignant tumors of the urogenital tract, including cancers of the endometrium, ovary, urinary bladder, and prostate, it has been possible to identify expression of gonadotropin-releasing hormone (GnRH) and its receptor as part of an autocrine system, which regulates cell proliferation. The expression of GnRH receptor has also been identified in breast cancers and non-reproduct...
Amplification of fibroblast growth factor receptor 1 (FGFR1) occurs in approximately 10% of breast cancers and is associated with poor prognosis. However, it is uncertain whether overexpression of FGFR1 is causally linked to the poor prognosis of amplified cancers. Here, we show that FGFR1 overexpression is robustly associated with FGFR1 amplification in two independent series of breast cancers...
Background: Breast cancer is the most common cancer in women, containing approximately one third of all illnesses in women. Assessment of molecular markers is valuable in predicting the outcome of disease and decision making for optimal treatment. The purpose of this study was to determine the relationship between estrogen and progesterone receptors with Her-2, Ki67, P53, and clinicopathologica...
