Breast Cancer Genetic and Molecular Subtype Impacts Response to Omega-3 Fatty Acid Ethyl Esters.

Only registered users can translate articles

Epidemiological studies have correlated frequent omega-3 (n-3) fatty acid consumption with a lower risk for breast cancer; however, recent prospective studies have been less conclusive. Efforts in the preventive setting have focused on the use of n-3 fatty acids, and the pharmaceutical ethyl esters

Omega-3-Acid Ethyl Esters Block the Protumorigenic Effects of Obesity in Mouse Models of Postmenopausal Basal-like and Claudin-Low Breast Cancer.

Only registered users can translate articles

Obesity induces chronic inflammation and is an established risk and progression factor for triple-negative breast cancers, including basal-like (BL) and claudin-low (CL) subtypes. We tested the effects of dietary supplementation with ethyl esters of the marine-derived anti-inflammatory omega-3 fatty

Modulation of Breast Cancer Risk Biomarkers by High-Dose Omega-3 Fatty Acids: Phase II Pilot Study in Premenopausal Women.

Only registered users can translate articles

Higher intakes of the omega-3 eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) relative to the omega-6 arachidonic acid (AA) have been variably associated with reduced risk of premenopausal breast cancer. The purpose of this pilot trial was to assess feasibility and explore the effects of

In vivo tumor accumulation of nanoparticles formed by ionic interaction of glycol chitosan and fatty acid ethyl ester.

Only registered users can translate articles

In this study, novel fatty acid ethyl ester (FAEE)-based glycol chitosan (GC) nanoparticles were prepared through an electrostatic interaction. Additionally, the tumor accumulation of the FAEE-GC nanoparticles was evaluated in order to determine the enhanced permeability and retention (EPR) effect

Synthesis and evaluation of amino acid-based radiotracer 99mTc-N4-AMT for breast cancer imaging.

Only registered users can translate articles

OBJECTIVE This study was to develop an efficient synthesis of (99m)Tc-O-[3-(1,4,8,11-tetraazabicyclohexadecane)-propyl]-α-methyl tyrosine ((99m)Tc-N4-AMT) and evaluate its potential in cancer imaging. METHODS N4-AMT was synthesized by reacting N4-oxalate and 3-bromopropyl AMT (N-BOC, ethyl ester).

Synthesis of (99m)Tc-EC-AMT as an imaging probe for amino acid transporter systems in breast cancer.

Only registered users can translate articles

OBJECTIVE This study was to develop a (99m)Tc-labeled alpha-methyl tyrosine (AMT) using L,L-ethylenedicysteine (EC) as a chelator and to evaluate its potential in breast tumor imaging in rodents. METHODS EC-AMT was synthesized by reacting EC and 3-bromopropyl AMT (N-BOC, ethyl ester) in

One-step synthesis of biodegradable curcumin-derived hydrogels as potential soft tissue fillers after breast cancer surgery.

Only registered users can translate articles

A one-step synthesis of a curcumin-derived hydrogel (curcumin content of 25-75 mol %) is reported. Curcumin is incorporated into the hydrogel backbone and cross-linked through biodegradable carbonate linkages. Curcumin as a part of the polymer backbone is protected from oxidation and degradation,

Antiproliferative and antiinflammatory coxib-combretastatin hybrids suppress cell cycle progression and induce apoptosis of MCF7 breast cancer cells

Only registered users can translate articles

In our study, some newly synthesized aryl-substituted pyrazole derivatives mimicking cis-diphenylethylene scaffold of two apoptotic inducing agents celecoxib and combretastatin A-4 were found to have strong antiproliferative as well as antiinflammatory activities. Among these coxib-combretastatin

Injectable delivery system of 2-methoxyestradiol for breast cancer therapy using biodegradable thermosensitive poly(organophosphazene) hydrogel.

Only registered users can translate articles

2-Methoxyestradiol (2-ME) has been reported to have antiangiogenic and antitumor activity. Its biomedical application is limited due to its poor water solubility resulting in its low bioavailability. Poly(organophosphazenes) containing l-isoleucine ethyl ester, ethyl-2-(O-glycyl)lactate, and

Glutathione elevation by gamma-glutamyl cysteine ethyl ester as a potential therapeutic strategy for preventing oxidative stress in brain mediated by in vivo administration of adriamycin: Implication for chemobrain.

Only registered users can translate articles

Oxidative stress in heart and brain by the cancer chemotherapeutic drug adriamycin (ADR), used for treating solid tumors, is well established. Long-term treatment with ADR in breast cancer patients has led to symptoms of cardiomyopathy. Less well recognized, but increasingly well documented, is

Chemopreventive and anti-breast cancer activity of compounds isolated from leaves of Abrus precatorius L.

Only registered users can translate articles

The present study focuses on isolation and evaluation of the anti-cancer activity of compounds from the leaves of Abrus precatorius. The bioassay-directed strategy was adopted using chromatographic, gas chromatographic-mass spectrum analysis, nuclear magnetic resonance and X-ray crystallography

Modulation of Breast Cancer Risk Biomarkers by High-Dose Omega-3 Fatty Acids: Phase II Pilot Study in Postmenopausal Women.

Only registered users can translate articles

Associational studies suggest higher intakes/blood levels of the omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) relative to the omega-6 arachidonic acid (AA) are associated with reduced breast cancer risk. We performed a pilot study of high-dose EPA + DHA in

Optical Imaging of Glucose Uptake and Mitochondrial Membrane Potential to Characterize Her2 Breast Tumor Metabolic Phenotypes.

Only registered users can translate articles

With the large number of women diagnosed and treated for breast cancer each year, the importance of studying recurrence has become evident due to most deaths from breast cancer resulting from tumor recurrence following therapy. To mitigate this, cellular and molecular pathways used by residual

Novel "ruthenium cyclopentadienyl"-peptide conjugate complexes against human FGFR(+) breast cancer.

Only registered users can translate articles

In this work we explored the possibility of improving the selectivity of a cytotoxic Ru complex [RuCp(PPh3)(2,2'-bipy)][CF3SO3] (where Cp = η5-cyclopentadienyl) TM34 towards FGFR(+) breast cancer cells. Molecular dynamics (MD) simulations of TM34 in a phosphatidylcholine membrane model pinpointed

In Vitro and In Vivo Anti-Breast Cancer Activities of Some Newly Synthesized 5-(thiophen-2-yl)thieno-[2,3-d]pyrimidin-4-one Candidates.

Only registered users can translate articles

In this study, some of new thiophenyl thienopyrimidinone derivatives 2-15 were prepared and tested as anti-cancer agents by using thiophenyl thieno[2,3-d]pyrimidinone derivative 2 as a starting material, which was prepared from cyclization of ethyl ester derivative 1 with
