BACKGROUND
Previous studies have shown that the poly (adenosine diphosphate-ribose) polymerase (PARP) level is a promising indicator of breast cancer. However, its prognostic value remains controversial. The present meta-analysis evaluated the prognostic value of PARP expression in breast
OBJECTIVE
Poly(adenosine diphosphate-ribose) polymerase (PARP) plays a key role in DNA repair and cellular stress response. Inhibitors of PARP show promising clinical activity in metastatic, triple-negative or BRCA-mutated breast cancer.
METHODS
We investigated cytoplasmic PARP (cPARP) and nuclear
Inhibitors of the poly(adenosine triphosphate-ribose) polymerase (PARP)-1 enzyme induce synthetic lethality in cancers with ineffective DNA (DNA) repair or homologous repair deficiency, and have shown promising clinical activity in cancers deficient in DNA repair due to germ-line mutation in BRCA1
The activities of NTPDase (EC 3.6.1.5, apyrase, CD39) and 5'-nucleotidase (EC 3.1.3.5, CD73) enzymes were analyzed in platelets from breast cancer patients. Initially, patients were compared in terms of length (years) of tamoxifen use. The following groups were studied: breast cancer patients who
Although preclinical and clinical studies on poly-(adenosine diphosphate ribose) polymerase (PARP) inhibitor alone or in combination with DNA-damaging agents have shown promising results, further research to improve and broaden the application scope of this therapeutic approach is needed. The main
Phytoestrogens have been demonstrated to inhibit tumor induction; however, their molecular mechanisms of action have remained elusive. The present study aimed to investigate the effects of a phytoestrogen, apigenin, on proliferation and apoptosis of the human epidermal growth factor receptor 2
OBJECTIVE
The interactions between cancer cells and platelets have been recognized to play an important role in cancer progress as well as metastasis, and interference with cancer-platelet interactions is an attractive strategy for cancer therapy. In the present study, two β-nitrostyrene
DNA repair is essential for the survival of both normal and cancer cells. An elaborate set of signaling pathways detect single-strand and double-strand DNA breaks and mediate either DNA repair or apoptosis if the damage is too great to repair. Poly(adenosine diphosphate [ADP]-ribose) polymerases
Metastatic triple-negative breast cancer (mTNBC) patients tend to have a poor overall survival. The primary goals of treatment focus on palliation of symptoms and improvement in overall survival (OS). Single-agent sequential chemotherapy with anthracycline or taxane has remained the cornerstone of
Alpha-tocopherol ether-linked acetic acid analog [2,5,7,8-tetramethyl-2R-(4R, 8R-12-trimethyltridecyl) chroman-6-yloxyacetic acid (alpha-TEA)] is a novel form of vitamin E effective at killing cancer cells but not normal cells. alpha -TEA alone and together with methylseleninic acid (MSA) and
Breast cancer is one of the most frequent tumors in women, and BRCA1 and BRCA2 genes play a major role in the hereditary susceptibility for this disease. Until the age of 70 women carrying a mutation in BRCA1 or BRCA2 gene have a 45-85% probability of developing breast cancer, and 11-62% probability
Triple-negative breast cancer (TNBC) is defined by the lack of immunohistochemical expression of the estrogen and progesterone receptors and human epidermal growth factor receptor 2 (EGFR2). Most TNBC has a basal-like molecular phenotype by gene expression profiling and shares clinical and
OBJECTIVE
The use of nanoparticles has seen exponential growth in the area of health care, due to the unique physicochemical properties of nanomaterials that make them desirable for medical applications. The aim of this study was to examine the effects of crystal phase-nanostructured titanium
