digoxin/breast neoplasms

The objective of this study was to determine the cytotoxicity, antiproliferative activity, and apoptosis induction activity of two modified glycosides - digoxin and proscillaridin A - conjugated to a generation 3 polyamidoamine dendrimer (G3 PAMAM-NH(2)) in human breast cancer cells. The results

We examined the effects of three cardiac glycosides, ouabain, digoxin and proscillaridin A, on the proliferation of estrogen independent MDA-MB-231 breast cancer cells. In terms of reduction in cell viability, the compounds rank for both 24 h and 48 h of incubation in MDA-MB-231 cells in the order

OBJECTIVE Digoxin resembles estrogen chemically and may have estrogenic effect. We hypothesized that digoxin use might increase breast cancer incidence and examined if use might be associated with risk of breast cancer, categorized by estrogen receptor (ER) status. To determine if being under care

Digoxin has been shown to have an estrogenic effect and is associated with increased risk of gynecomastia and estrogen-sensitive cancers such as breast and uterus cancer. These findings, particularly recent observations of increased breast cancer risk, raise questions about the safety of digoxin use

BACKGROUND Digoxin use is associated with increased incidence of breast and uterus cancers. We postulated that digoxin use might affect tumor characteristics and increase relapse risk in women with breast cancer. METHODS Incident breast cancer cases in Danish women (n = 49,312; 1995 to 2008) were

Despite preclinical evidence supporting anti-cancer effects of cardiac glycosides, epidemiologic studies consistently show elevated breast cancer risk in digoxin users. We studied this association in the Nurses' Health Study cohort to evaluate influences of screening mammography and

10 biopsy specimens of primary breast tumours from 10 patients were classified histopathologically into 8 ductal carcinomas and 2 lobular carcinomas. Portions of tumour of approximately 1 mm3 were cultured in Medium 199 buffered with 20 mM Hepes for 48 h with or without addition of digoxin at

Rolapitant is a selective and long-acting neurokinin-1 receptor antagonist approved in an oral formulation in combination with other antiemetic agents for the prevention of delayed chemotherapy-induced nausea and vomiting in adults. Four open-label phase 1 studies evaluated the safety and drug-drug

The aim of this study was to investigate the effects of digoxin on the chemoresistance of human breast cancer cell line MCF-7/adriamycin (ADR) and its underlying mechanism. MCF-7 and MCF-7/ADR cells were designated as control and ADR groups, respectively. MCF-7/ADR cells in ADR + digoxin group

Several epidemiological studies, some of which included several thousand women, have shown a link between digoxin exposure and the risk of breast cancer. A cohort study of women with angina, identified in the Danish Prescription Registry, showed a statistically significant increase in the risk of

BACKGROUND Laboratory and epidemiologic studies have suggested a modifying effect of cardiac glycosides (for example, digoxin and digitoxin) on cancer risk. We explored the association between digoxin treatment and invasive breast cancer incidence among postmenopausal Danish women. METHODS We used

OBJECTIVE Digoxin is a kind of plant-derived cardiac glycoside that is mainly used to treat heart diseases, especially in congestive heart failure or arrhythmia. However, its potentiality presented in anti-tumor remains unexplored. The purpose of this study was designed to investigate the beneficial

Three derivatives of ouabain, digoxin and proscillaridin A containing the carboxylic group instead of the lactone moiety were synthesized and examined for cytotoxicity in human breast cancer cells. Evaluation of the cytotoxicity of these compounds employing an MTT assay and inhibition of

We evaluated the cytotoxicity and underlying mechanisms of cardiac glycosides, including digoxin, ouabain and proscillaridin A, on the proliferation of breast cancer MCF-7 cells. In terms of inhibition of cell proliferation of MCF-7 cells, the compounds rank in the order proscillaridin
