Plant antioxidants protect cells against oxidative stress. Because oxidative stress (measured by different biomarkers) is observed in breast cancer patients, the aim of this study was to establish the effects of a polyphenol-rich extract of Aronia melanocarpa (final concentration of 50 microg/mL, 5
Since mechanisms involved in the relationship between oxidative stress and breast cancer are still unclear, the aim of our present study was to evaluate oxidative/nitrative modifications of blood platelet proteins by measuring the level of biomarkers of oxidative/nitrative stress such as carbonyl
The present study evaluates the antioxidant activity of two Aronia melanocarpa cultivars-Viking and Aron-and of Aronia prunifolia hybrid in relationship with their phytochemical composition regarding the contents of total phenolics, flavonoids, procyanidins, and monomeric anthocyanins. The
Consumption of berries and red fruits rich in polyphenols may contribute to the reduction of colon cancer through mechanisms not yet understood. In this study, we investigated the response of subconfluent Caco-2 cells (a human colon carcinoma model) to repetitive exposure (2 h a day for a 4-day
Since the extract from berries of Aronia melanocarpa presents antioxidative properties in plasma and in blood platelets, not only from healthy group, but also from patients with benign breast diseases and in patients with invasive breast cancer before surgery, the aim of our present study was to
OBJECTIVE
Extending work with brain tumours, the hypothesis that micronutrients may usefully augment anticancer regimens, chokeberry (Aronia melanocarpa) extract was tested to establish whether it has pro-apoptotic effects in AsPC-1, an established human pancreatic cell line, and whether it
In breast cancer patients (before and during anti-cancer therapy) oxidative/nitrative damage to various molecules is observed. Furthermore, anti-cancer treatments may also influence the hemostatic properties of blood platelets and plasma. The aim of our study was to assess the effect of
Cigarette smoke (CS) and dietary factors play a major role in cancer epidemiology. At the same time, however, the diet is the richest source of anticancer agents. Berries possess a broad array of health protective properties and were found to attenuate the yield of tumors induced by individual
Different low-molecular-weight thiols, including glutathione, cysteine, and cysteinylglycine are physiological free radical scavengers. On the other hand, homocysteine may play a role as an oxidant. The aim of our present study was to establish in vitro the effects of the commercial extract of
BACKGROUND
Berries contain several phytochemicals, such as phenolic acids, proanthocyanidins, anthocyanins and other flavonoids. There has been growing interest in a variety of potential chemopreventive activities of edible berries. The potential chemopreventive activity of a variety of small
The effects of 10 different extracts of fruits and berries on cell proliferation of colon cancer cells HT29 and breast cancer cells MCF-7 were investigated. The fruits and berries used were rosehips, blueberries, black currant, black chokeberries, apple, sea buckthorn, plum, lingonberries, cherries,
The aim of the present study was to evaluate the immunomodulatory activity of Aronia in combination with apple pectin in patients with breast cancer in the course of postoperative radiation therapy. Monoclonal antibodies were used to assay specific T cell subsets. Tests were performed prior to and
Cancer stem cells (CSCs) as a subpopulation of cancer cells are drug-resistant and radiation-resistant cancer cells to be responsible for tumor progress, maintenance and recurrence of cancer, and metastasis. This study isolated and investigated a new cancer stem cell (CSC) inhibitor derived from
Cancer stem cells (CSCs) are drug-resistant and radiation-resistant cancer cells that are responsible for tumor progression and maintenance, cancer recurrence, and metastasis. Targeting breast CSCs with phytochemicals is a new paradigm for cancer prevention and treatment. In this study,
Anthocyanin-rich extracts, potent antioxidants and commercially available food coloring agents, have been reported to inhibit growth of various cancer cell lines. We investigated the effect of semipurified anthocyanin-rich extract from fruits of Aronia meloncarpa, on normal colon and colon cancer
